Agricultural Sector and Marketing Reforms – eNAM, Model APMC Act, Eco Survey Reco, etc.

Structural issues in agri-marketing

Note4Students

From UPSC perspective, the following things are important :

Prelims level: APMC Act

Mains level: Paper 3- Structural issues in agri-marketing.

The article discusses the structural issues that may not go away with the reforms announced by the government recently. Issues like inadequacies in APMC infrastructure, regulation of APMCs need are discussed in detail.

What is the issue?

  • The Union government signalled the intention to enact a new central law.
  • The new law would override existing state regulations that restrict the farmer from legally selling to anyone other than a buyer licensed by the local Agricultural Produce Marketing Committee (APMC).
  • The decision to push for a central law comes after dissatisfaction with two decades of partial and uneven reforms by different states.

So, will the change in the law solve the marketing problem?

  •  This will be overstating the power of legal reform in guaranteeing economic freedom and outcomes.
  • The problems farmers face are of two type-
  • 1) Problems that are a result of vested, monopolistic interests.
  • 2) Problems that are rooted in larger structural conditions that significantly weaken their terms of engagement in agricultural markets.
  • Type 1 may be addressed by regulatory intervention.
  • But type 2 will need location-specific policies, well-directed investment, and well-functioning agricultural institutions.
  • So, solving either of these problems require consensus, coordination and capacity in which the states will need to play a major role.

Why do farmers sell their produce outside APMC mandis?

  • The dominant narrative is that farmers are forced to sell their produce only to licensed APMC traders.
  • But the reality is that even today the majority of Indian farmers sell their produce to small-scale and largely unlicensed traders and intermediaries.
  • This is true, especially of small and marginal cultivators.
  • But, if farmers are bound by law to sell in APMC mandis, why are so many of them selling outside?

But, do we have enough mandis?

  • At least part of the answer to the question of why farmers sell outside mandis is that India still doesn’t have enough mandis.
  • Over the decades, most states in general, and specific regions in particular, have hugely under-invested in the basic infrastructure required to create viable, primary wholesale markets within easy physical reach of farmers.
  • The 2017 Doubling Farmers Income Report estimates that in addition to the current 6,676 principal and sub-market yards under APMCs India needs over 3,500 additional wholesale markets.
  • Approximately 23,000 rural periodic markets (or haats) have also suffered long-standing neglect.
  • So, the new allocation towards market infrastructure must be fully utilised to build up an appropriately designed physical marketing ecosystem, especially in remote regions.
  • Most importantly, unlike in the past, this process should engage deeply with farmers and traders in each location to avoid misdirected and misplaced infrastructure and assets.

Regulatory reforms in mandis needed

  • Where APMC mandis do exist and have established themselves as dominant market sites, mandi committees have typically done everything in their power to restrict competition.
  • Obtaining a licence for a new entrant — has most often proved to be a bureaucratic nightmare and a costly affair.
  • This is where regulatory reform to remove conflicts of interests, enable the entry of new buyers, and facilitate the flow of trade both within and outside the mandi system is absolutely crucial.
  • No state has done enough in this direction, but here too there are cautionary lessons.

Perils of complete deregulation: Example of Bihar

  • Complete deregulation, as we have seen in the decade following Bihar’s repeal of its APMC Act in 2006, does not necessarily transform agricultural markets and spur competition.
  • Even after all restrictions were lifted, there was little uptake in direct procurement by formal players in the state.
  • When corporations entered the maize market in a big way, they chose to buy from larger traders and aggregators and not from farmers.
  • Most farmers have seen little change in marketing practice and continue to sell to village traders as they had done before the repeal.
  • Where private markets have emerged — mainly for horticultural produce — they are constituted and run by local traders and commission agents.
  • But across the system, traders complain about deteriorating infrastructure.
  • And the regulatory vacuum has led to the proliferation of brokers to deal with counter-party risk in growing and dynamic commodity markets such as maize.

Benefits of limited degree of regulation: MP and Karnataka example

  • Madhya Pradesh and Karnataka have undertaken some degree of regulatory reform instead of repeal.
  • In these states, we do observe, at least to some extent, the fruits of competition.
  • In the early 2000s, MP granted ITC a licence to set up procurement hubs outside mandi yards.
  • Establishment of ITC procurement hubs not only resulted in price competition, but also from electronic weighing and quick payments, as mandis upgraded in response.
  • But ITC’s procurement channel was understandably restricted to select commodities (and qualities), seasons and farms within its own commercial strategy.
  • These limitations revealed the mandi’s comparative advantage as a permanent multi-buyer, multi-commodity market for all local producers.
  • The key lesson to draw from studies of direct procurement and contracting is the need for a regulatory architecture that enables both new and existing systems to respond, adapt, and compete.

Issue of intermediation

  •  Small traders and intermediaries exist — and persist — because they are able to respond — in cash, credit, time and place — to the multiple needs of farmers and firms across the interconnected domains of production, marketing, processing and consumption.
  • This is not to say that they do not exploit farmers when the opportunity arises.
  • So, the organised and technologically driven procurement and marketing systems will only work if they manage to address the real constraints that farmers face on the ground, especially access to credit, inputs, storage, transport, and timely payments.
  • Most of these constraints originate in the relations of land ownership and access and the limits and exclusions they impose on smallholding farmers and landless cultivators.
  • Simply put, farmers will not be in a position to exercise any newly granted regulatory freedom in the market if they cannot overcome these constraints.
  • Equally, while increasing competition for intermediaries is desirable, their elimination is a misguided — and indeed dangerous — objective if one does not respect or replace the roles and risks that they cover.

Issue of re-regulation and new barriers to entry

  • Agriculture is at the very heart of the essential economy and our food system runs on the backs of small-scale producers, traders, commission agents, processors, wholesalers, retailers, and labourers.
  • Regulatory reform to increase competition must not degenerate into re-regulation that unduly favours large-scale consolidation and channel control by erecting new barriers to entry and operation for agro-commercial MSMEs.

The UPSC asked a direct question about the APMC Act in 2014- ” There is also a point of view that Agriculture Produce Market Committees (APMCs) set up under the State Acts have not only impeded the development of agriculture but also have been the cause of food inflation in India. Critically examine.”

Conclusion

While going for the reforms government must consider the issues underlying the problems and try to address them. We must recognise and strengthen the diversity, dynamism, enterprise, and resilience of India’s agricultural markets.

MGNREGA Scheme

Ensuring MGNREGA lives up to its potential

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Provisions of MGNREGA

Mains level: Paper 2- Issues and scope for improvement in MGNREGA

With migrant workers returning home, work demand under MGNREGA is bound to rise. Sensing that the government increased the allocation to MGNREGA. This article suggests some steps to make the MGNREGA more effective in catering to this surge in the wake of the pandemic. Some issues that plague the scheme are also examined at the end. So, what are the suggestion? and what are the issues? Read to know….

Acknowledgement of the importance of MGNREGA

  • The government made an allocation of an additional Rs 40,000 crore as part of the stimulus package.
  • This is an acknowledgement of the importance of MGNREGA.
  • The most important part of MGNREGA’s design is its legally-backed guarantee for any rural adult to get work within 15 days of demanding it.
  • This demand-based trigger enables the self-selection of workers and gives them an assurance of at least 100 days of wage employment.

Let’s put allocation in context of World Bank recommendations

  • Since 2012, an average of 18 per cent of the annual budgetary allocation for MGNREGA has been spent on clearing pending liabilities from the previous years.
  • Even this financial year began with pending wage and material liabilities of Rs 16,045 crore.
  • An allocation of Rs 1 lakh crore for FY 2020-21 would mean that approximately Rs 84,000 crore is available for employment generation this year.
  • This will still be the highest allocation for MGNREGA in any year since the passage of the law.
  • However, the allocation, which amounts to 0.47 per cent of the GDP continues to be much lower than the World Bank recommendations of 1.7 per cent for the optimal functioning of the programme.

Some immediate steps to ensure the MGNREGA lives up to its potential

  • First, state governments must ensure that public works are opened in every village.
  • Workers turning up at the worksite should be provided work immediately, without imposing on them the requirement of demanding work in advance.
  • Second, local bodies must proactively reach out to returned and quarantined migrant workers and help those in need to get job cards.
  • Third, at the worksite, adequate facilities such as soap, water, and masks for workers must be provided free of cost. For reasons of health safety, MGNREGA tools should not be shared between workers.
  • The government should provide a tool allowance to all workers — some states are already providing such an allowance.
  • Fourth, procedures for implementing MGNREGA must be simplified but not diluted.
  • The pandemic has demonstrated the importance of decentralised governance.
  • Gram panchayats and elected representatives need to be provided with adequate resources, powers, and responsibilities to sanction works, provide work on demand, and authorise wage payments to ensure there are no delays in payments.
  • Fifth, as per a study by the RBI, more than half the districts in the country are under-banked.
  • The density of bank branches in rural India is even more sparse.
  • At this time, payments need to not only reach bank accounts on time, but cash needs to reach the workers easily and efficiently.
  • The limited coverage of bank infrastructure in rural areas must not be made a hurdle.
  • Attempts to distribute wages in cash, sans biometric authentication, must be rolled out.
  • Sixth, there needs to be flexibility in the kinds of work to be undertaken, while ensuring that the community and the workers are the primary beneficiaries.

Issuse with MGNREGA

  • Over the last few years, MGNREGA had begun to face an existential crisis.
  • Successive governments capped its financial resources, and turning it into a supply-based programme.
  • Workers had begun to lose interest in working under it because of the inordinate delays in wage payments.
  • With very little autonomy, gram panchayats had begun to find implementation cumbersome.
  • Barring a few exceptions, state governments were only interested in running the programme to the extent funds were made available from the Centre.
  • Allocating work on demand, and not having enough funds to pay wages on time was bound to cause great distress amongst the workers and eventually for the state too.
  • As a result, state governments had begun to implement MGNREGA like a supply-driven scheme, instead of running it like a demand-based guarantee backed by law.

Consider the question “With migrant workers returning to villages in the wake of corona pandemic, demand for work is likely to increase. In light of this, discuss the utility of MGNREGA and challenges it may face.”

Conclusion

With nearly eight crore migrant workers returning to their villages, and with an additional allocation for the year, this could be a moment for the true revival of MGNREGA. A revival led by workers themselves.

Mahatma Gandhi National Rural Employment Guarantee Act, 2005

  • The Act aims at enhancing the livelihood security of people in rural areas by guaranteeing hundred days of wage employment in a financial year to a rural household whose adult members (at least 18 years of age) volunteer to do unskilled work.
  • The central government bears the full cost of unskilled labour, and 75% of the cost of material (the rest is borne by the states).
  • It is a demand-driven, social security and labour law that aims to enforce the ‘right to work’.
  • Ministry of Rural Development (MRD), Government of India in association with state governments, monitors the implementation of the scheme.

Explained: Contract Farming and its benefits

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Contract Farming

Mains level: Contract Farming and its feasibilty

The Odisha government has promulgated an ordinance allowing investors and farmers to enter into an agreement for contract farming in view of the continuing uncertainties due to the pandemic.

Practice question for mains:

Q. What is Contract Farming? Examine its potentials and feasibility from the perspective of farmers’ interests.

Moving on with Odisha’s law

  • The Odisha ordinance is aimed at facilitating both farmers and sponsors to develop mutually beneficial and efficient contract farming system.
  • It is argued that the new system will lead to improved production and marketing of agricultural produce and livestock while promoting farmers’ interest.
  • The agreement will be entered into between the contract farming sponsor, who offers to participate in any component or entire value chain including preproduction, and the contract farming producer (farmers), who agree to produce the crop or rear the livestock.
  • Both the loans and advances given by the sponsor to the producer can be recovered from the sale proceeds of the produce.
  • And in no case realized, recovery can be through the sale or mortgage or lease of the land in respect of which the agreement has been entered into.

What is Contract Farming?

  • Contract farming (CF) can be defined as agricultural production carried out according to an agreement between a buyer and farmers, which establishes conditions for the production and marketing of a farm product or products.
  • Typically, the farmer agrees to provide agreed quantities of a specific agricultural product.
  • These should meet the quality standards of the purchaser and be supplied at the time determined by the purchaser.
  • In turn, the buyer commits to purchase the product and, in some cases, to support production through, for example, the supply of farm inputs, land preparation and the provision of technical advice.

Some business models in CF

1) Informal model – This model is the most transient and speculative of all contract farming models, with a risk of default by both the promoter and the farmer. However, this depends on the situation: interdependence of contract parties or long-term trustful relationships may reduce the risk of opportunistic behaviour.

2) Intermediary model – In this model, the buyer subcontracts an intermediary (collector, aggregator or farmer organisation) who formally or informally contracts farmers (a combination of the centralised/ informal models).

3) Multipartite model – This model can develop from the centralised or nucleus estate models. It involves various organisations such as governmental statutory bodies alongside private companies and sometimes financial institutions.

4) Centralized model – In this model, the buyers’ involvement may vary from minimal input provision (e.g. specific varieties) to control of most production aspects (e.g. from land preparation to harvesting). This is the most common CF model.

Advantages of Contract Farming:

To the farmers:

  • It helps in skilling of farmers as they learn to use various resources efficiently like fertilizer, pesticides and get in touch with new technology in some cases.
  • Farmers get the opportunity for diversification of crops.
  • Price risk is drastically reduced as many contracts specify prices in advance.
  • Contract farming can open up new markets which would otherwise have been unavailable to small farmers. The farmers can also get easy credit from the Bank under contractual agreements.
  • In the case of agri-processing level, it ensures a consistent supply of agricultural produce with quality, at the right time and lesser cost.

To the Client:

  • They get uninterrupted & regular flow of raw material of high quality which helps in protection from fluctuation in market pricing.
  • Long term planning of business is possible as they have a dedicated supplier base of raw material.
  • Concept of contract farming can be extended to other crops also which helps to generate goodwill for the organisation.

Limitations

  • Contract farming arrangements are often criticized for being biased in favour of firms or large farmers while exploiting the poor bargaining power of small farmers.
  • Problems faced by growers like an undue quality cut on produce by firms delayed deliveries at the factory, delayed payments, low price and pest attack on the contract crop which raised the cost of production.
  • Contracting agreements are often verbal or informal in nature, and even written contracts often do not provide legal protection in India that may be observed in other countries. Lack of enforceability of contractual provisions can result in a breach of contracts by either party.
  • Single Buyer – Multiple Sellers (Monopsony).
  • Adverse gender effects – Women have less access to contract farming than men.

Foreign Policy Watch: India-China

Rising incidences of Chinese Transgressions

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Not Much

Mains level: India-China border disputes

As tensions remain high between Indian and Chinese soldiers, the number of recorded Chinese transgressions across the disputed India-China border surged by 75 per cent in Ladakh in 2019, and the Chinese forays into Indian Territory in the first four months of the current year have also witnessed an increase compared to the same period last year.

Chinese Transgression:

    • The border between India and China is not fully demarcated and the Line of Actual Control (LAC) is neither clarified nor confirmed by the two countries.
    • This leads to different perceptions of the LAC for the two sides while soldiers from either side try to patrol the area.
    • Observation Methods: Use of surveillance equipment, face-offs by patrols, reliable indications by locals, or evidence left by the Chinese in the form of wrappers, biscuit packets etc. in an unmanned area.
    • Official data shows that 80% of Chinese transgressions across the LAC since 2015 have taken place in four locations of which three are in eastern Ladakh in the western sector.
      • These areas of eastern Ladakh are Pangong Tso, Trig Heights and Burtse.
      • The fourth area is the Dichu Area/Madan Ridge area (Arunachal Pradesh) of the Eastern sector.
  •  Implications of Increased Number of Transgressions:

    • It is an indicator of increased Chinese assertiveness.
    • Even if there are no major incidents, it should not be taken lightly.
    • So far, there has been no major standoff between the two sides after the 73-day Doklam standoff on Sikkim-Bhutan border in 2017.

Concerns

  • India is worried about the tensions at Naku La in Sikkim and at Galwan river and Pangong Tso in Ladakh.
  • The increased transgressions lead to more tensions between both countries which are already struggling to contain the Covid-19 pandemic.
  • Nepal’s recent behaviour on the Mansarovar Link Road raising the border map issue also raises Indian concerns.
  • The constant accusations on each other also cause tensions and disrupt the peace on borders.
    • Recently, Chinese media accused India of building defence facilities in the Galwan Valley region of the contested Aksai Chin area.
  • India and China are both nuclear-armed countries with strong militaries and the constant border conflicts are not a desirable thing.

Way Forward

  • In the Wuhan and Mahabalipuram summits, both China and India had reaffirmed that they will make efforts to ensure peace and tranquility in the border areas.
  • On 1st April, 2020 India and China completed their 70 years of diplomatic relations.
  • Both countries have resolved border issues peacefully in the past four decades which gives the hope that the tensions will subside soon.
  • Establishment of peace between the two big powers of such an important geopolitical region is essential for their own growth and development as well as for maintenance of global peace.

Indian Air Force Updates

What is the ‘Sonic Boom’ that rattled Bengaluru city?

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Sonic Boom, Mach Number

Mains level: India's missile programme

The ‘loud sound’ heard in Bengaluru a few days back, which puzzled lakhs of city dwellers, was revealed to have emanated from an IAF test flight involving a supersonic profile. The sonic boom was probably heard while the IAF aircraft was decelerating from supersonic to subsonic speed between 36,000 and 40000 feet altitude.

Note:

We often get to hear about updates in  India’s missile programme. UPSC may ask a basic physics question asking fundamental differences between various Mach number and its differences.

What is a ‘sonic boom’?

  • Sound travels in the form of waves which are emitted outwards from its source.
  • In air, the speed of these waves depends on a number of factors, such as the temperature of the air and altitude.
  • When an aircraft travels at supersonic speed – meaning faster than sound (>1225 kmph at sea level) – the field of sound waves moves to the back of the craft.
  • A stationary observer thus hears no sound when a supersonic flight approaches since the sound waves are at the rear of the latter.
  • At such speeds, both newly created as well as old waves, are forced into a region at the aircraft’s rear called a ‘Mach cone’, which extends from the craft and intercepts the Earth in a hyperbola-shaped curve, and leaves a trail called the ‘boom carpet’.
  • The loud sound that is heard on the Earth when this happens is called a ‘sonic boom’ (resembles bomb-blast sound).

Impacts

  • When such aircraft fly at a low altitude, the sonic boom can become intense enough to cause the glass to crack or cause health hazards.
  • Overland supersonic flights have thus been banned in many countries.

Supersonic flights

  • In 1947, the American military pilot Chuck Yeager became the first to breach the sound barrier, flying the Bell X-1 aircraft at 1127 kmph.
  • Since then, many supersonic flights have followed, with advanced designs allowing speeds of over Mach 3, or three times the speed of sound.
  • According to the IAF website, India’s fastest jets include the Sukhoi SU-30 MKI (Mach 2.35) and the Mirage-2000 (Mach 2.3).

Back2Basics: Traverse of sound

  • From a stationary source, such as a television set, sound waves travel outwards in concentric spheres of growing radii.
  • When the source of sound is moving – e.g, a truck– the successive waves in front of the truck get closer together, and the ones behind it spread out.
  • This is also the cause of the Doppler effect– in which bunched waves at the front appear at a higher frequency to a stationary observer, and spread out waves that are behind are observed at a lower frequency.
  • As long as the source of the sound keeps moving slower than the speed of sound itself, this source– say a truck or a plane – remains nested within the sound waves that are travelling in all directions.

Mach number

  • The ratio of the speed of the aircraft to the speed of sound in the gas determines the magnitude of many of the compressibility effects.
  • Because of the importance of this speed ratio, aerodynamicists have designated it with a special parameter called the Mach number in honour of Ernst Mach, a late 19th-century physicist who studied gas dynamics.
  • Subsonic conditions occur for Mach numbers less than one, M < 1.
  • As the speed of the object approaches the speed of sound, the flight Mach number is nearly equal to one, M = 1, and the flow is said to be transonic.
  • Supersonic conditions occur for Mach numbers greater than one, 1 < M < 3.
  • For speeds greater than five times the speed of sound, M > 5, the flow is said to be hypersonic.
  • The Space Shuttle re-enters the atmosphere at high hypersonic speeds, M ~ 25. Under these conditions, the heated air becomes ionized plasma of gas and the spacecraft must be insulated from the high temperatures.

Promoting Science and Technology – Missions,Policies & Schemes

[pib] Certification of ‘Quantum Entanglement’

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Quantum Entanglement (QE)

Mains level: Quantum mechanics and its applications

Indian scientists have developed a novel protocol to find out whether a pair of electrons are in an entangled state so that they can be safely used as resources for facilitating quantum information processing tasks.

Trending in news this year is the Quantum Technology, (As it used to be until last year were- the Internet of Things (IoT) CSP 2019, Artificial Intelligence (AI) etc.)

Must read all this news in a loop:

National Mission on QC

Quantum Coin

Quantum Supremacy

What is Quantum Entanglement (QE)?

  • QE is the name given to a special connection between pairs or groups of quantum systems, or any objects described by quantum mechanics.
  • It is one of the biggest parts of quantum mechanics that makes it hard to understand in terms of the everyday world.
  • When we look at particles, we usually say that each particle has its own quantum state. Sometimes, two particles can act on one another and become an entangled system.
  • When a pair or group of particles can only be described by the quantum state for the system, and not by individual quantum states, we say the particles are “entangled”.

Going bit technical here-

  • It is the physical phenomenon that occurs when a pair or group of particles is generated; interact, in a way such that the quantum state of each particle of the pair or group cannot be described independently of the state of the others.
  • Entangled states are key resources to facilitate many quantum information processing tasks and quantum cryptographic protocols.

Why decode the Entanglement?

  • Entanglement is fragile and is easily lost during the transit of photons through the environment.
  • Hence it is extremely important to know whether a pair of photons are entangled, in order to use them as a resource.
  • Verification of entanglement requires the use of measurement devices, but such devices may be hacked or compromised.

How to secure QE?

  • Device-independent self-testing (DIST) is a method that can be used in order to overcome such a possibility.
  • This method enables the verification of entanglement in an unknown quantum state of two photons without having direct access to the state, or complete trust in the measurement devices.
  • The theory relies on the application of the quantum uncertainty principle while implementing full device independence is a difficult task.

Back2Basics: Quantum Mechanics

  • Quantum mechanics (QM) is a fundamental theory in physics which describes nature at the smallest scales of energy levels of atoms and subatomic particles.
  • It is the body of scientific laws that describe the wacky behaviour of photons, electrons and the other particles that make up the universe.

Genetically Modified (GM) crops – cotton, mustards, etc.

[pib] Alternative Dwarfing Genes in Wheat

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Rht14 and Rht18

Mains level: Alternatives to stubble burning

Scientists at Pune based Agharkar Research Institute (ARI) an autonomous institute of the Department of Science and Technology has mapped two dwarfing genes Rht14 and Rht18 in wheat that can reduce stubble volume.

Note: One may wonder why the name of research institution has not been skipped here!

Q. With reference to the Genetically Modified mustard (GM mustard) developed in India, consider the following statements:

  1. GM mustard has the genes of a soil bacterium that give the plant the property of pest-resistance to a wide variety of pests.
  2. GM mustard has the genes that allow the plant cross-pollination and hybridization.
  3. GM mustard has been developed jointly by the IARI and Punjab Agricultural University.

Which of the statements given above is/are correct? (CSP 2018)

(a) 1 and 3 only

(b) 2 only

(c) 2 and 3 only

(d) 1, 2 and 3

Rht14 and Rht18

  • The researchers have mapped the dwarfing genes on chromosome 6A in durum wheat, and DNA-based markers were developed for a better selection of these genes in wheat breeding lines.
  • These genes are associated with better seedling vigour and longer coleoptiles (sheath protecting the young shoot tip).
  • These DNA based markers are being used at ARI for marker-assisted transfer of these genes in Indian wheat varieties, so as to make them suitable for sowing under rice stubble-retained conditions and dry environments.
  • Wheat lines with these alternative dwarfing genes, apart from reducing crop residue burning, can allow deeper sowing of wheat seeds to avail advantage of residual moisture in the soil under dry environments.
  • Wheat lines with these alternative dwarfing genes, apart from reducing crop residue burning, can allow deeper sowing of wheat seeds to avail advantage of residual moisture in the soil under dry environments.

Significance

  • In India, close to twenty-three million tonnes of leftover rice residues are annually burnt by farmers to get rid of the straw and prepare their fields for sowing wheat, which is the next crop, resulting in air pollution.
  • Burning of leftover rice crop residue has serious implications for the environment, soil, and human health.
  • Therefore, there is a need to include alternative dwarfing genes in wheat improvement programs.
  • The dwarfing genes Rht14 and Rht18 in wheat conferred a plant height reduction comparable to the Rht1 alleles while retaining early vigour in wheat seedlings, but do not affect coleoptile length and seedling shoot length.
  • These can, therefore, be utilized as an alternative dwarfing gene to Rht1 for deep sowing conditions or in fields with retained stubble.
  • The improved wheat lines which are being developed at ARI will help reducing stubble burning incidences under the rice-wheat cropping system.
  • These lines will also allow deeper sowing of wheat seeds to avail advantage of residual moisture in the soil, therefore, saving valuable water resources and reduce the cost of cultivation to farmers.
