ABSTRACT

A field trial was conducted to standardize row spacing and suitable genotype at College of Agriculture, Shivamogga. Three guar genotypes viz., RGC-1003, RGC-936 and HG-365 were grown at four different spacing viz., 45 cm x 15 cm, 30 cm x 15 cm, 45 cm x 10 cm and 30 cm x 10 cm. Experiment was laid out in factorial Randomized complete block design with three replications. Among the genotypes, RGC-1003 recorded significantly higher growth parameters viz., plant height (53.06 cm), number of leaves (17.38), number of branches (8.28), number of clusters plant-1 (7.94), number of pods plant-1 (29.31), number of seeds    pod-1 (7.07), 100 grain weight (3.33 g), pod length (4.62 cm) and grain yield (898.18 kg ha-1), stover yield (1931.39 kg ha-1) with a harvest index (0.32) and quality parameters viz., Endosperm (33.96 %), Protein (31.68 %), Gum (31.09 %), Viscosity (245.75 cps-1) as compared to other genotypes. Among the spacing, plants grown at 30 cm x 10 cm recorded significantly higher plant height (49.51 cm), number of leaves (16.39), number of branches (8.07), number of clusters plant-1 (7.18), number of pods plant-1 (23.48), number of seeds pod-1 (6.76), 100 grain weight (3.22 g), pod length (4.47 cm) and grain yield (743.89 kg ha-1), stover yield (1629.94 kg ha-1) with a harvest index (0.34) and quality parameters viz., Endosperm (33.49 %), Protein (30.94 %), Gum (30.36 %), Viscosity (236.47 cps-1) as compared to other planting density.

Key words:Genotypes, Guar, Spacing, Yield, and Quality.
