Effects of urea and sunn hemp on nitrogen use efficiency and physiological traits related to Japonica rice yield
Main Article Content
Abstract
Application of sunn hemp as a sole fertilizer could provide nitrogen use efficiency (NUE), tiller number, leaf area index (LAI), crop growth rate (CGR), biomass and grain yield higher than application of urea as a sole fertilizer. Correlation coefficients (r) among some physiological traits including LAI, CGR, NUE, NUE for grain yield (NUEg) and agronomic traits consisting of tiller number, biomass and grain yield were significantly positive resulted which ranged between 0.65 and 1.00. The results indicated that application of sunn hemp as green manure can promote growth and yield of Japonica rice and tend to be a good choice for supplying nitrogen in Japonica rice production.
