Mains Paper 3: Agriculture| Major crops cropping patterns in various parts of the country, different types of irrigation and irrigation systems
From UPSC perspective, the following things are important:
Prelims level: Zero Tillage
Mains level: Benefits of Zero tillage
Tillage is Labour intensive
- Most farmers do not own bullocks and can’t afford to hire a tractor for tilling to grow cotton
- It involves deployment of extra labourers for sowing in place of a bullock drawn plough.
- This will be slightly costly but it gets compensated as seed germination percentage is quite high and the crop stays healthy.
- Farmers in Telangana have dozen-year experience in sowing cotton in the zero tillage method and suggest that it is best suited for the cash crop and yields good results.
- Zero tillage involves sowing of seeds along the markers on the string which is held by two male labourers on either end of the land.
- The seeds sown in this fashion do not encounter the crust in the soil the way it happens in the tilling method.
- Also, the seeds encounter least resistance to take roots unlike the hardened crust.
- While sowing seeds in furrows made by a plough requires administration of fertilisers at that stage, there is no need for Diammonium Phosphate to be administered to the seeds which are directly sown through zero tillage.
- The germination and health of the plant is as good as those seeds which had a fertiliser booster.
- The soil retains moisture which is quite beneficial for cotton plant growth.
- It retains organic matter and improves soil biological fertility.
