ABSTRACT

Residual effect of phosphorus on the growth, yield and economics of succeeding greengram to cotton hybrids was stuched in imgated cotton-greengram sequence. Results indicated that higher drymatter production and higher grain yield were obtained from greengram when greengram was grown after the harvest of hybrid cotton (TCHB 213) when cotton was applied with mussoorie rockphosphate [(MRP) (100% PP, requirementll enriched with FYM + phosphobacteria application + application of 100 per cent recommended phosphorus to greengram as single superphosphate (SSP). However, higher benefit: cost ratio was observed when greengram was grown after the harvest of hybrid cotton, when cotton was manured with 100 per cent PZ0 5 requirement through MRP enriched with FYM + phosphobaeteria + 50 per cent PzOs requirement through SSP to greengram.
