Abstract:
A field experiment was conducted on medium black calcareous soil at the Instructional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh (Gujarat) during the summer season of 2019 in randomized block design with three replications, comprised with 10 treatments of three plant growth regulators spray at single stage as well as double stage. Foliar application of 100 ppm IAA at flowering as well as capsule formation stage recorded significantly higher values of growth parameters viz., plant height, number of branches/plant, dry matter accumulation, crop growth rate, early maturity and yield attributes viz., number of capsules/plant, number of healthy seeds/capsule, less number of chaffy seeds/capsule and test weight along with higher seed and stover yields as well as higher value of economics over rest of the treatments including Control.
