Effect of Integrated Nutrients and Foliar Spray of Bio-regulators On Growth, Yield, and Quality of Okra [abelmoschus Esculentus (L.) Moench] Under Western Plains Zones of Utter Pradesh

Abstract

An investigation was carried out at HRC of SVP University of Agriculture & Technology, Meerut (UP) during the year 2019 to examine the “Effect of integrated nutrient management and foliar spray of bio- regulators on growth, yield and quality of Okra [Abelmoschus esculentus (L.) Moench] under Western Plains Zones of Uttar Pradesh”. A total of nine treatments consisted twenty seven treatment combinations with inorganic, organic and bio regulators were used in the study. The field experiment was conducted out in factorial Randomized Block Design (FRBD) and replicated thrice. The maximum plant height 45 Days and at harvesting stage, number of branches, leaf area, and chlorophyll content was noted with 75 per cent inorganic fertilizers and 6.0 t/ha FYM , whereas foliar application of bioregulators viz. 5 ppm brassinoids and 150 ppm salicylic acid resulted maximum growth in okra. Maximum fruit length, fruit diameter, number of fruits per plant, yield per plant, yield per plot, yield per ha, protein content, crude fiber content, available nitrogen, phosphorus and potassium, soil bacteria, fungi and actinomycetes were observed with 50 per cent inorganic fertilizers and 12.0 t/ha FYM along with foliar spray of 5 ppm brassinoids and 150 ppm salicylic acid. Among the treatment combinations, treatment combination 75 per cent inorganic fertilizers and 6.0 t/ha FYM, whereas foliar application of bioregulators viz. 5 ppm brassinoids and 150 ppm salicylic acid showed maximum yield, quality, soil parameters and economic yield of okra. Among the treatment combinations, 75 per cent inorganic fertilizers and 6.0 t/ha FYM along with bioregulators 5 ppm brassinoids and 150 ppm salicylic acid produced maximum growth while 50 per cent inorganic fertilizers and 12.0 t/ha FYM along with foliar spray of 5 ppm brassinoids and 150 ppm salicylic acid showed maximum yield, quality, soil health and net return, benefit cost ratio in okra.
