Yield and yield components of sorghum (Sorghum bicolor) as influenced by integrated nutrient management system and its residual effect on chickpea (Cicer arietinum)

摘要

A field experiment was conducted to study the effect of integrated nutrient management system in sorghum-chickpea cropping sequence in the vertisols of Rahuri, Maharashtra under irrigated conditions. Application of 75 per cent RDF+FYM+biofertilizer to sorghum proved beneficial in significantly improving the yield components over inorganics alone resulting in increase in the grain yield of sorghum. The residual effect of INMS to sorghum was not significant in respect of yield component and yield of chickpea. However, the treatment 50 per cent RDF+FYM was numerically better than rest of the treatments. The nodule count of chickpea showed higher values where FYM was combined with reduced levels of RDF. The graded levels of RDF to chickpea resulted in significantly higher values of yield components and yield of chickpea due to 100 per cent RDF. However, 50 per cent RDF was at par with that of 100 per cent RDF in respect of yield components and grain yield..
