Abstract

We studied the growth, biological yield and nutrient uptake of Indian mustard under residual effect of different green leaf manuring and nitrogen levels applied to preceding rice crop. The results indicated that residual effect of Gliricidia sepium green leaf manuring @ 10 t ha-1 resulted in significantly higher growth characters at 60 days after sowing, biological yield and nutrient uptake at harvest. However, it was found statistically at par with Leucaena leucocephala and Sesbania aculeata regarding growth and biological yield while, with Leucaena leucocephala for nutrients uptake. Among N levels, the residual fertility of 100% RDN fetched significantly higher growth, biological yield and nutrients uptake by succeeding mustard crop. It was remained statistically at par with lower N levels i.e. 75 and 50% RDN in terms of growth and biological yield. Green leaf manuring maintained gradually high N mineralization rates throughout the rice-mustard sequence and it is the best alternative
