Author(s):

Abstract:
Growth and yield attributes of cotton were evaluated with the application of varying doses of plant growth regulators during kharif 2020. The experiment was laid out in Randomized Block Design and replicated thrice, conducted at Agricultural College Farm, Bapatla. The treatments comprised of T1: control, T2: Mepiquat chloride 50 ppm at 45 DAS; T3: Mepiquat chloride 50 ppm at 75 DAS; T4: Maleic hydrazide 30ppm at 45 DAS; T5: Maleic hydrazide 30ppm at 75 DAS; T6: Cycocel 60ppm at 45 DAS; T7: Cycocel 60ppm at 75 DAS; T8: Mepiquat chloride 50 ppm at 45 DAS and 75DAS; T9: Maleic hydrazide 30ppm at 45 DAS and 75 DAS; T10: Cycocel 60ppm at 45 DAS and 75 DAS. The results indicated that the highest drymatter accumulation at harvest and stalk yield were recorded in control plot. Maximum number of bolls plant-1, number of picked bolls plant-1 and seed cotton yield were noticed in Mepiquat chloride 50 ppm at 45 + 75 DAS which was on par with T9: Maleic hydrazide 30 ppm at 45 DAS and 75 DAS; T10: Cycocel 60 ppm at 45 DAS and 75 DAS.
