RESIDUAL EFFECTS OF DIFFERENT AMENDMENTS AND N LEVELS APPLIED TO THE PRECEDING RICE CROP ON THE SOIL PROPERTIES AND YIELD OF SUCCEEDING GREENGRAM CROP

Abstract

In a field study with different amendments and N levels applied to the preceding rice in a light textured soil under two irrigation regimes revealed that the residual effect of coir-pith significantly increased the available N, P and K and organic carbon contents in soil. The highest greengram grain yield was obtained under the residual effect of clayey soil under I, regime but on par with coir-pith treatment. The residual effect of N levels on soil properties and yield were non-significant.

Keywords: RESIDUAL EFFECT, AMENDMENTS, N LEVELS, GREENGRAM, YIELD
