To study the relative performance of three genotypes of cluster bean under different row spacing and fertility levels on quality, yield and yield attributes in cluster bean (Cyamops tetragonoloba
L.) field experiment was conducted during kharif 2012. Results from the experiment indicated that genotype HG100 recorded the highest number of pods/ plant (48.65) followed by HGS 8-1 (46.50) and least by HG 563 (C) (40.17). Genotype HGS 8-1 recorded the highest number of seeds/ pods (7.93), 100 seed weight (3.35 g), grain yield (8.85q/ha) and gum % (32.52%) followed by HGS 100 (7.65), (3.16 g), grain yield (8.78qha-1) and gum % (30.98%) followed by HG 563 (C) (6.29), (3.08 g) grain yield (7.17 q/ha) and gum % (30.61%). Highest content of crude protein (29.57%) was recorded by HG 563 (C) followed by HGS 8-1 (28.73%) and closely followed by HG100 (28.71 %). Row spacing 45 cm found better over 30 cm with respect to gum and protein content. Application of 20 kg N + 40 kg P2O5 /ha significantly increased the pods/ plant, grain yield, gum and protein content from 40.36 to 49.84, 7.38 to 9.15 q/ha, 30.67 to 32.07 % and 28.62 to 29.35 % respectively over 10 kg N + 20 kg P2O5 /ha.
Key words:Genotype, pod/ plant, seeds/plant, pod length, seed weight, grain yield, gum and protein content.
