Abstract
The present investigation entitled “Effect of plant growth retardants on growth seed yield and quality of okra.” was carried out during the year 2019-20 at Instructional cum demonstration Farm, Department of Vegetable Science, Faculty of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, to ascertain the effect of different growth retardants and their concentrations on growth, seed yield and quality, with a view to find out the suitable growth retardant and its concentration on better growth, seed yield and quality of okra. The experiment was laid out in Randomized Block Design with three replications. The experiment consist of growth retardants viz. CCC (400, 500, 600 ppm), MH (200, 300, 400 ppm), Ethrel (200, 300 400 ppm), and one treatment of control. The experiment was thus conducted with ten treatments.
The treatment having foliar application of Cycocel 500 ppm at 30 and 50 days after sowing was found significantly better in term of vegetative growth parameters viz. dwarfness in plant, minimum in internodal length, maximum number of leaves plant-1, internodes plant-1, branches plant-1 and leaf area, reproductive growth parameters like minimum days required to flower initiation, days required to 50 percent flowering, days required for first fruiting and days required for first and last harvesting; maximum in yield and yield attributes viz. number of fruits plant-1, length of fruit, diameter of fruit, number of seeds fruit-1, weight of seeds fruit-1, Seed yield plant-1, Seed yield plot-1 and Seed yield hectare-1 (13.41q ha-1) as well as quality parameters viz. test weight of seed, graded seed yield percentage and germination percentage in okra.
Description
The present experiment was carried out during Kharif season of academic year 2019-20, at Instructional Farm, Department of Vegetable Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.). The experiment was conducted in Randomized Block Design with three replications and ten treatment combinations. Methods of foliar application of PGRs (three) used as plant growth retardants and their concentrations viz. Cycocel (400, 500 and 600 ppm), Maleic Hydrazide (200, 300 and 400 ppm), Ethrel (200, 300 and 400 ppm).
