Abstract:
Water use efficiency in Vaishali is very poor and could be improved. Pollution of ground water through inefficient use of fertilizers, pesticides and other chemicals and poor disposal mechanism for waste is also on the rise and needs to be minimized. Therefore, a study was conducted in four blocks of Vaishali district namely Vaishali, Lalganj, Patepur and Jandaha by taking six farmers fields in each block. Thus altogether experiment was conducted on the fields of twenty four farmers regarding wheat sowing by RCT and Conventional methods. For the experiment in case of effect on soil fertility by zero tillage wheat as compared to conventional method of sowing mainly three methods were usedie first the sowing was done on surface seeding which is nothing but the simples of the zero tillage system in which soil is not disturbed and the wheat is placed on the soil surface. In the second method, wheat was sown by zero tillage machine in which wheat was placed in a narrow ground in the soil in V shape along with fertilizer and the third experiment was conducted by combining tillage done by a rotavator with seeding and planting was done in a single pass. Thus, the final results of the effect of soil fertility in case of zero tillage and conventional method was observed. Six farmers field sample from five points were collected for this and it has been observed that soil fertility significantly increased in both the methods except phosphorus. It was due to inadequate use of phosphorus fertilizer after harvesting of the rice crop stubbles were earlier decomposed in zero tillage technique and added adequate organic matter in depth by 43.6% and 66.7% as compared to 21.0% as compared to 21.0% and 36.0% in both depth by conventional method. Nitrogen was added about 10% more in upper soil layer and 21% more is 15-30 cm soil layer. Potassium was also 9% more in upper soil layer. Therefore zero tillage can improve the soil fertility.
