Effect of GA3 and NAA on growth and yield parameters of broccoli (Brassica oleracea var. italica) var. Pusa KTS-1

Abstract

The present investigation was carried out on “Effect of GA3 and NAA on growth and yield parameters of broccoli (Brassica oleracea var. italica) var. Pusa KTS -1” at Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand during Rabi season of the year 2019-20. The experiment was laid out in Randomized Block Design replicated thrice with nine treatments. Among all the different treatments foliar application of GA3 50 mg/l recorded significantly, maximum plant height (52.65 cm) at 45 days ATP, plant height (67.20 cm) at harvesting time, number of leaves (27.30) at harvest, diameter of stem at harvest (46.11 mm), leaf length (33.77 cm), leaf width (24.41 cm), early curd initiation (40 days), significantly the highest curd diameter (18.93 cm), maximum main curd weight (626 g), maximum volume of curd (466 cm3), minimum days to final harvesting (49.67), highest yield 671.67 g/plant, 19.31 kg/plot and 22.35 t/ha was found in treatment GA3 50 mg/l.
