Why in the News?
The combination of assured government support and scientific advancements in breeding technologies has made rice and wheat the most preferred crops among Indian farmers, while other crops lag due to lack of similar incentives and innovations.
Why do farmers prefer rice and wheat?
- Assured Procurement at MSP: The government provides near-guaranteed purchases of rice and wheat at Minimum Support Prices (MSP), reducing market risk. Eg: In Punjab, rice area increased from 29.8 lakh hectares in 2015-16 to 32.4 lakh hectares in 2024-25 due to consistent MSP support.
- Lower Yield Risk Due to Irrigation and Research Support: Rice and wheat are mostly grown under irrigated conditions and benefit from superior public research, leading to more stable yields. Eg: Wheat variety HD-3385, released in 2023, offers 6 tonnes/hectare yield with resistance to rust diseases and adaptability to different sowing times.
- Continuous Breeding Innovations and Higher Returns: These crops have seen regular improvements through breeding, enhancing productivity, stress tolerance, and input efficiency. Eg: Genetically-edited rice variety Kamala yields up to 9 tonnes/hectare and matures faster, saving water and fertilizer costs.
What drives yield growth in these crops?
- Genetic Improvements and Breeding Innovations: Continuous breeding has led to development of high-yielding, stress-resistant varieties. Eg: Wheat variety HD-3385, released in 2023 by ICAR, yields an average of 6 tonnes/hectare with a potential of 7.3 tonnes, and is resistant to all three major rusts (yellow, brown, and black).
- Improved Agronomic Practices and Technology Adoption: Advanced farming practices like early sowing, use of fertiliser-responsive varieties, and direct seeding have boosted productivity. Eg: Direct-Seeded Rice (DSR) technology eliminates the need for nursery and transplanting, saving water and labour, and supporting yield levels up to 10 tonnes/hectare in some hybrid varieties.
- Public Research and Extension Support: Rice and wheat receive consistent support from government research institutions, unlike many other crops. Eg: The CRISPR-Cas edited rice variety Kamala, developed by ICAR in 2024, produces 450-500 grains per panicle (vs. 200-250 in parent variety), yields up to 9 tonnes/hectare, matures 15-20 days earlier, and requires less fertiliser and water.
How has government policy influenced the cropping patterns in states?
- Minimum Support Price (MSP) and Procurement Assurances: Farmers prefer crops with assured government procurement at MSP, reducing market risk. Eg: In Punjab, rice area increased from 29.8 lakh hectares in 2015-16 to 32.4 lh in 2024-25 due to near-guaranteed MSP procurement, while cotton area declined from 3.4 lh to 1 lh.
- Skewed Research and Input Support: Rice and wheat have received consistent research and extension support, unlike pulses or oilseeds. Eg: ICAR has developed multiple improved wheat and rice varieties (e.g., HD-3385, Kamala), while no major breakthrough has happened in cotton since Bt cotton (2002-06).
- Irrigation Infrastructure Bias: Government investment in irrigation has favoured crops like rice and wheat, making them less yield-risk prone. Eg: In Madhya Pradesh, wheat area rose from 59.1 lh to 78.1 lh and rice from 20.2 lh to 38.7 lh, as irrigation expansion supported these water-reliant crops.
Which innovations improved rice varieties?
- Semi-Dwarf and High-Yielding Varieties: Introduction of semi-dwarf varieties reduced lodging and increased fertiliser response and yields. Eg: IR-8, released in 1966, was the first semi-dwarf rice variety, yielding 4.5–5 tonnes/hectare in just 130 days, compared to 1–3 tonnes in traditional varieties over 160–180 days.
- Gene Editing using CRISPR-Cas Technology: Advanced gene-editing allows precision improvements in yield and stress tolerance. Eg: Kamala, a GE mutant of Samba Mahsuri developed by ICAR in 2024, yields up to 9 tonnes/hectare, matures earlier, and has 450–500 grains per panicle (vs. 200–250 in the original).
- Abiotic Stress Tolerance Breeding: Development of varieties tolerant to drought, salinity, and heat stress for resilience in changing climates. Eg: Pusa DST Rice 1, a GE version of Cottondora Sannalu, with edited DST gene, shows improved tolerance to drought and salt stress, enabling cultivation in marginal soils.
Way forward:
- Diversify MSP and R&D Focus: Extend assured procurement and research support to pulses, oilseeds, and millets to reduce over-reliance on rice and wheat.
- Promote Sustainable Practices: Encourage water-saving technologies like direct-seeded rice, crop rotation, and climate-resilient varieties to ensure long-term agricultural sustainability.
Mains PYQ:
[UPSC 2024] What are the major challenges faced by Indian irrigation system in recent times? State the measures taken by the government for efficient irrigation management.
Linkage: Farmers prefer rice and wheat partly because of access to irrigation which reduces yield risk. Challenges and management of irrigation systems directly impact this aspect of their decision-making.
