Andhra Pradesh
Sangareddy: The Agriculture Department wants to encourage ‘zero tillage’ technique in some parts of the district to reduce soil erosion and the cost of cultivation. The method is in vogue in the East and West Godavari, Guntur and Krishna districts where farmers recorded yield of 8 to 10 quintals of black and green gram per acre. Zero tillage involves broadcasting of seed on the lands with the stubble of kharif paddy left intact in the field. The leftover paddy stubble acts as natural manure and reduces the need for inorganic manure. The pulses which have the inherent quality of fixing nitrogen help the soil gain natural fertilizer in return. Contrary to the common belief that ‘fine tillage’ would add to soil fertility the new method which is being experimented in Mahabubnagar and by Kaveri Seeds Company in Medak district proved that ‘no tillage’ is good as it does not disturb top soil. The unstable and dry land soil in Telangana region gets eroded if it is ploughed too deep. Moreover farmers could save at least 15 to 20 days of precious time by not tilling the soil. Mahabubnagar gainsMr. Rao said the experiment in Mahabubnagar resulted in the yield of almost 15 quintals per acre of maize by adopting zero tillage method. The farmers there have recognised the advantage of the early maturity of the zero tillage crops reducing the risk of power shortage in the month of April. Shortage of water in the tassel and milking stage could lead to a loss of almost 20 to 40 per cent of the yield. The time saved by not tilling the land helps the pulses or maize to mature earlier saving them from power shortage.
