Abstract

Effects of organic manure (FYM) on yield of pearl millet, efficiency of applied nitrogen and soil fertility were studied under rainfed farming for seven years (1983-1989) in Jodhpur. Pearl millet yield was strongly dependent on the distribution of rainfall, particularly at the reproductive phase. Total biomass yield (grain +straw) was highest for plots receiving FYM @ 10 t ha-1 ,annum-1, in good rainfall as well as drought years. Fertilizer nitrogen upto 80 kg ha-1 increased yield in good rainfall years, but in drought years, no significant effect was observed beyond 40 kg N ha-1. Application of fertilizer N along with FYM further increased yield. Yield with 40 kg N ha-1 + FYM was nearly equal to that obtained with 80 kg fertilizer N ha-1 alone. FYM significantly increased the utilization efficiency of fertilizer N by crop and status of organic carbon, available N, P and micro·nutrients in soil. Residual N effects were observed for plots receiving FYM but no such residual effects were observed for fertilizer N.
