ABSTRACT

Field experiments were conducted during rabi seasons of 1997–98 and 1998–99 to find out the response of groundnut (Arachis hypogaea L.) to the residual effect of different nitrogen management practices adopted to preceding khari! rice. Residual effect of khari! rice treatments altered the yield attributes, yield and nitrogen uptake of groundnut. Application of 50%GMN +50%FVMN 10 preceding rice crop resulted in the highest tota1 dry matter, pods plantl, pod weight, shelling percentage, pod and kernel yields haulm yield as well as nitrogen uptake of groundnut. The increase In pod yield of groundnut with application of 50% GM N + 50% FVM N to preceding rice crop was 39.53% and 18.2496 over no nitrogen to rice and 30.6296 and 15.98116 over 100% fertilizer N to rice during 1997–98 and 1998–99, respectively.
