Correlation studies in clusterbean as influenced by varieties and foliar appplication

Abstract

A field experiment was conducted during the rainy season 2014-15 to assess effect of foliar application of iron and to evaluate performance of clusterbean [Cyamopsis tetragonoloba (L.) Taub] varieties. The twenty treatment combinations consisting of five clusterbean varieties (RGC-986, RGC-1003, RGC-1033 RGC-1055 and RGC-1066) and foliar sprays treatment of 0.5% FeSO4 (control branching, flowering and branching + flowering) were tested in randomized block design with three replications. Results revealed that variety RGC-1033 proved significantly superior and economically profitable compared to rest of varieties in respect of dry matter accumulation, growth indices like CGR, RGR and LAI, pods/plant, seeds/pod and test weight. Similar, the seed yield (1816 kg/ha), stover yield (3787 kg/ha) and biologicalyield (5602 kg/ha) were also significantly higher with variety RGC-1033. Among the correlation studies the maximum correlation found between N uptake and seed yield.
