RESIDUAL INFLUENCE OF FYM, FYM+UREA AND UREA ON CROP YIELD AND SOIL FERTILITY STATUS IN ASHWAGANDHA AS SEQUENCE CROP

ABSTRACT
The residual effect of fertilizer provides favourable response of crops and helps to supply major nutrients to the sequential crop. The secondary and minor nutrients may also remain available after first crop which offers beneficial effects to the second (sequential) crop. Soluble nitrogen fertilizers offer maximum residual effects in the high yields of second crop. The uses of fertilizers for two crop in sequencing manner one after another reduces excessive utilization of fertilizers thus decreases chances of adverse effects associated with high amount of fertilizers. The approach of sequencing or residual fertilizers also reduces cost of cultivation and maintains soil fertility. Considering these all facts we planned a study to observe effects of FYM, FYM+Urea and Urea on the Uraria picta and then the remaining residual fertilizer on the growth and yield of the Withania somnifera which grew as second crop. Study observed appreciable response of residual fertilizers (FYM, FYM+Urea and Urea) on the growth and yield of sequential crop of Withania somnifera
