Department of Agriculture requests ryots to produce nutritious manure and apply it in the land to get high yields in groundnut crops.
According to A. N. Asaithambi, Deputy Director of Agriculture, Erode, Farmers Training Center, in rainfed agriculture, some techniques can be used to get a fairly stable income.
The most important of these is preparing nutritious manure. Of the nutrients in the soil, manichathu is the most important nutrient that crops need in large quantities.
It is essential for crops to take root and thrive. The sambalsathu in the soil is not readily available to the crop.
These nutrients can be applied to the crop immediately by applying them through nutrient-rich manure.
Research has shown that ‘fertilized crops have higher yields in rainfed fields’. In Tamil Nadu, only 10 per cent of the irrigated area is adequately fertilized.
More than 39000 acres of irrigated groundnut is cultivated annually in Erode district. Farmers are reluctant to fertilize rainfed groundnuts due to unpredictable rains and drought.
In addition, the use of natural fertilizers has declined due to the unavailability of adequate manure and its high cost. In this situation it is necessary to adopt a new technique of fertilizing the crop.
Applying this simple, nutritious manure, which is not expensive and very simple, can ensure huge yields even under rainfed conditions.
How to prepare? It should be prepared at least one month before sowing rainfed groundnut. One cart (about 300 kg) of compost (crow dung) should be mixed with 25 kg of super phosphate and 30 kg of potash per acre and covered with clay soil and kept in the shade.
Or spray water well and whip the pile tightly. It would check wastage of nutrients of the fertilizer in the air. When it is left for a month, the manure is nourished and supplemented. One month later mix 9 kg urea with this and spray in the field when sowing groundnut seeds.
When sowing the seed by tractor, this nourished manure should be sprayed evenly across the field before sowing and then sown. In this way, the nutrients required for rainfed groundnut are available to the crop without loss. The manure increases the growth of root, and yield.
The manure is available to the crop immediately without wastage, improves the physical properties of the soil and increases water retention capacity in the soil.
As the number of microorganisms in the soil increases, other nutrients are available to the crop and the yield increases. In addition, the risk of chemical fertilization during drought is reduced.
In addition, at least two bags (400 gms) per acre of groundnut ‘Rhizobium’; and two bags ‘Phosphobacteria’ bio-fertilizers can be mixed separately with manure to get extra yield.
Amidst the risks of increasing manure scarcity and rising input costs, farmers can instead produce good quality nutritious manure in their fields and get better yields under the method.
