Abstract

The effect of dual cropping of green manure on productivity of semi-dry rice was studied during 2003 and 2004. The yield attributing parameters viz, productive tillers, panicle length, filled grains and 100 grain weight were significantly superior under paired row sowing (PRS) of rice with Sesbania aculeata under weed free condition. The highest yield (3.53 t ha−1) was recorded with paired row sowing (PRS) of rice with Sesbania aculeata under weed free condition and comparable with normal sowing of rice with herbicide application + hand weeding twice.
