Response of clusterbean varieties to various inter and intra row spacings in rainfed alfisols

Abstract

A field experiment was conducted to study the influence of spacing on clusterbean varieties in alfisols of scarce rainfall zone under rainfed situation for consecutive three kharif seasons of 2013, 2014 and 2015 at the Agricultural Research Station, Ananthapuram of Andhra Pradesh. Pooled data revealed that higher yield was recorded with branched varieties (447 kg ha -1 ) than unbranched varieties (445 kg ha -1 ). Unbranched variety produced higher haulm yield. Among crop geometry, 22.5 x 10 cm recorded higher seed yield of 512 kg ha -1 while lowest seed yield of 393 kg ha -1 obtained with 45x10 cm. Among crop geometry tested, higher haulm yield was registered with 45x7.5 and 22.5x7.5 cm spacing resulted lowest haulm yield. Considering the economics and large scale availability of seed drills and planters with farmers sowing of cluster bean either branched or unbranched genotypes with 30 x 7.5 or 10 cm spacing was found optimum.
