Greengram was raised immediately 1 week after the harvest of rabirice in the same undisturbed lay out for two consecutive years, to find out the residual effect of puddling, water and weed management practices imposed to preceding rice on growth and yield of succeeding greengram. Germination percentage, root and shoot length, dry matter production, seed and haulm yields of succeeding greengram were recorded the highest values in normal puddling plots with irrigation at 1 day after disappearance of ponded water or continuous submergence imposed to preceding rice and both the treatments were on par with each other. Significantly the lowest values of the above growth parameters and yield of post rice greengram were recorded in intensive puddling plots with continuous submergence or irrigation at 1 day after disapperance of ponded water imposed to preceding rice due incresed bulk density on dying of the soil,which may restrict the root growth eventhough these intensive puddling plots recorded lower weed dry weight in greengram. Weed management practices employed for preceding rice were not statistically traceable with respect to bulk density of the soil, growth and yield of succeeding greengram. It was concluded that normal puddling treatments imposed to preceding rice recorded the better growth parameters and yield of succeeding greengram than intensive puddling treatments, irrespective of the water management practices followed for preceding rice, however the highest rice grain yield and rice equivalent yieds were recorded with intensive puddling treatments.
