Response of rainfed lowland rice to green manuring with Sesbania rostrata

Abstract

A 56-day-old Sesbania rostrata pre-rice green manure crop accumulated >6 t above-ground dry biomass ha-1. Consequently, green manuring alone improved the grain yield of the subsequent rainfed lowland rice Oryza sativa crop by 1.8 t ha-1 over that of the control. This increase was the same as that of the 60 kg N ha-1 treatment. Under rainfed lowland conditions in a relatively fertile soil, it is possible that all N requirement of the rice crop other than that which could be obtained from the native soil N may be provided by S. rostrata. -from Authors
