Performance of cluster bean cultivars under the application of various agrochemicals in Sub-Humid area of Rajasthan, India

A field experiment was conducted during the kharif season 2008 and 2009 to find out response of clusterbean to various growth regulators. The experiment was laid out under spit plot design where four varieties (RGC-936, RGC-1002, RGC-1003 AND RGC-1017 are taken as main plot treatment and seven growth substance (control, seed treatment with thiourea 500 ppm, foliar application of thiourea 500 ppm, seed+foliar application of thiourea 500 ppm, seed treatment with TGA 100ppm, foliar application of TGA 100 ppm and seed+foliar application of TGA 100ppm) as sub plot treatment and with three replications. Application of seed + foliar application with thiourea 500ppm on yield attributes viz., pods plant⁻¹, seeds pod⁻¹, weight of seeds pod⁻¹, test weight, seed yield plant⁻¹ showed significant increase i.e. 24.88g, 6.97g, 0.187g, 26.82g, 5.04g on pooled basis. The results revealed that the variety RGC-936 gave significantly higher number of pods per plant (24.85.00), seeds per pod (6.67), weight of seed per pod (0.179 g), test weight (26.09 g), and seed yield per plant (4.67 g). Seed+foliar application of thiourea 500ppm recorded significant improvement in yield and yield attributes on the pooled basis. The maximum net returns (Rs.2873/-) and B: C ratio (3.82) were recorded with the variety RGC-936.
