Abstract:
The present investigation entitled “Effect of plant growth regulators on growth, yield and quality parameters in sweet pepper (Capsicum annum L.) under naturally ventilated polyhouse” was conducted at Vegetable Research Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during two consecutive Rabi season 2020-21 and 2021-22 to find out the effect of PGRs and their spray schedules on sweet pepper under protected cultivation. The experiment was laid out in Factorial Randomized Block Design with 12 treatment combinations and replicated thrice. The experiment comprised four levels of plant growth regulators viz., NAA @ 50 ppm (P1), NAA @ 100 ppm (P2), Triacontanol @ 5 ppm (P3) and Triacontanol @ 10 ppm (P4) and three spray schedules viz., spray at 30 & 45 DAT (I1), spray at 30, 45 & 60 DAT (I2) and spray at 30, 45, 60 & 75 DAT (I3). higher monetary benefit (net return of Rs. 200102 and C:B ratio of 1:3.69) were observed with Triacontanol @ 10 ppm and spray schedule at 30, 45, 60 and 75 days after transplanting (DAT).
