abstract
The field experiments were conducted at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during rabi 2007-08 and 2008-09 to ascertain the effect of nipping growth regulators spray on chickpea varieties A-1 and ICCV-2. The varieties, A-1 recorded lower plant height, higher number of branches, number of pods (47.75) per plant, seed yield per plant and per ha (28.75 q) compared to ICCV-2 (25.52 q/ha). The seed quality parameters viz., 100 seed weight, seedling length (27.54 cm), dry weight (180.37 mg), vigour index (2301) were more in ICCV-2 compared to A-1. Among foliar sprays of growth regulators, the plants sprayed with NAA 50 ppm resulted in increase of plant height, number of productive branches (26.13), number of pods per pant (46.76), seed yield per ha (29.91 q) and was followed by triacontanol(1 ml/lit) with higher seed quality parameters. The interaction effect of varieties and growth regulators (VxS) indicated that, A-1 variety sprayed with 50 ppm NAA (V₁S₁)recorded relatively higher number of branches, pods per plant, pod weight per pant and seed yield per ha (32.29) and the other parameters were no significant.
