Influence of organic, inorganic and bio-fertilizers on growth, flowering, yield and quality attributes of bitter gourd (Momordica charantia L.) var. green long

Abstract

The present investigation entitled “Influence of organic, inorganic and bio-fertilizers on growth, flowering, yield and quality attributes of bitter gourd (Momordica charantia L) var. Green Long” was carried out during the year 2019-2020 in the Department of Horticulture, Sam Higginbottom University of Agriculture Technology & Sciences Prayagraj in the months of Feb 2019 to May 2019. The experiment was laid out in Randomized Block Design (RBD) with 11th treatments combinations with control. The results revealed that T10 50% RDF + FYM@20 tonnes/ha + Vermicompost@10 tonnes/ha was found suitable for application in winter season bitter gourd cultivation for better flowering, growth, fruit yield and quality viz., The maximum average vine length (cm) at 30, 60, 90 DAS were recorded 124.65cm, 243.77cm, 368.61cm respectively, number of branches per plant at 30, 60, 90 DAS were recorded 4.34, 8.56, 14.56 respectively, number of leaves per plant at 30, 60, 90 DAS were recorded 80.86, 128.58, 288.76 respectively, Days to first female flower emergence were recorded at 33.17days respectively, Days to first male flower emergence were recorded at 30.41days respectively, Node. No. to which 1st male flower appearance were recorded at 13.46 respectively, Node. No. to which 1st female flower appearance were recorded at 24.87 respectively, Days to first fruit picking were recorded at 45.88 days respectively, No. fruit per plant were recorded at 42.20 respectively, length of fruit were observed 25.47cm and width of fruit were observed 17.24cm, Average fruit weight were observed 69.52gm, total yield per plant were recorded 2.934kg, fruit yield were recorded 52.81(t ha-1), total soluble solids were observed 4.81(0Brix), ascorbic acid were observed 84.52 (mg100g-1) and Shelf life were recorded 8.74 days respectively. The highest yield benefit cost ratio (4.38) were obtained in treatment T7 50% RDF + Azotobacter under Prayagraj agro climatic condition.
