Abstract
Investigation on “Response of Pruning and Application of Micronutrient on Growth and Yield of Sweet Pepper (Capsicum annuum) cv. Raja” was undertaken with objective to increase the number of fruit and fruit weight of sweet pepper and to identify the days of pruning in shade net of sweet pepper. Present experiment conducted at Department of Horticulture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during the year 2019-2020 on sweet pepper cv. Raja. The experiment was conducted on well-established shade net with Factorial Randomized Block Design having two factor the Factor A consisted six levels of micronutrients viz. M1 chelated Zn 0.2%, M2 chelated Fe 0.2%, M3 chelated Bo 0.1%, M4 chelated Cu 0.1%, M5 chelated Mn 0.2%. M6 chelated Mix 0.2% and Factor B consisted two levels of pruning viz. P1 pruning 20 DAT. P2 pruning 30 DAT. Foliar applications of micronutrients were sprayed at two times, first spraying was done at 20 days after transplanting and second spraying was done at 30 days after transplanting. It was ensure that plant was sprayed in all directions. Pruning was done manually in all direction after counting number of branches per plant. The observation was recorded on growth parameter, fruit parameter, yield and quality parameter. With respect to foliar application of micronutrient chelated zinc M1 0.2% recorded significantly highest leaf area, fruit weight, fruit set percentage, diameter, length, plant height, ascorbic acid (mg/100 ml). Among the different pruning, treatment P2 i.e. pruning at 30 days after transplanting recorded significantly maximum fruit set, fruit weight, fruit diameter, yield per plant, ascorbic acid (mg / 100 ml). However minimum values were found in treatment P1 i.e. pruning at 20 days after transplanting. The treatment combination M1P2 (Chelated Zinc 0.2% + Pruning at 30 days after transplanting ) recorded significantly highest plant height, leaf area, maximum weight, fruit set, number of flower, chlorophyll content, number of fruit. Similarly, fruit chemical parameters i.e. ascorbic acid (mg/100 ml) was found better into M1P2 (Chelated Zinc 0.2 %+ Pruning at 20 days after transplanting).
