Abstract:
An experiment was conducted at Department of Vegetable Science, College of horticulture, Anantharajupeta to access the effect of foliar spray of plant growth regulators on the growth attributes. Among pinching treatments, P₃ (Pinching at 90 cm) recorded highest number of primary branches, stem girth, number of flowers per panicle, number of panicles per plant, pod set percentage, yield per plant. Here, un pinched plants recorded the highest plant height. Among growth regulators and chemicals, GA₃ @ 20 ppm (G₂) recorded highest plant height, number of primary branches and stem girth. KNO3 @ 0.5% (G₄) recorded highest number of flowers per panicle, number of panicles per plant, pod set percentage and yield per plant. Among interaction effects, P₁G₂ (No pinching along with GA₃ @ 20 ppm) recorded maximum plant height. P₃G₂ (Pinching at 90 cm plant height along with GA₃ @ 20 ppm) recorded highest number of primary branches, stem girth. P₃G₄ (Pinching at 90 cm along with KNO3 @ 0.5%) recorded highest number of flowers per panicle number of panicles per plant, pod set percentage and yield per plant.
