Influence of growth regulators on nutrient concentrations, nutrient uptake and quality parameters of cluster bean varieties

Abstract

A field experiment was conducted during the season kharif 2008 and 2009 to find out response of cluster bean varieties to growth regulators. RGC-936 recorded in significantly higher amount of total nitrogen (N), phosphorus (P) uptake and protein content during both the years over RGC-1017, RGC-1003 and RGC-1002. Seed + foliar application with thiourea @ 500 ppm recorded maximum total N and P uptake. Quality parameters viz. gum and protein in seed, were found highest in cultivar RGC 1017 which was at par with RGC-1002 and RGC-1003 and all these three varieties were significantly superior over RGC 936. Variety RGC-1017 recorded 15.3% higher gum content over RGC-936. Among the growth regulators. maximum gum content in seed were recorded with the seed + foliar application of thiourea @ 500 ppm. However, it was found statistically at par with the seed + foliar application of TGA @ 100 ppm and significantly superior to rest of the treatments in current study.
