The field experiment was conducted on a sandy clay loam soil during summer season of 2018 at the Instructional Farm, Bidhan Chandra Krishi Viswavidyalaya, Jaguli lying in indo-Gangetic plains of West Bengal under humid subtropical climate to study the effect of three frequencies of irrigation at 7, 10 and 15 days interval and four nutrient management viz., 100% RDF, 75% RDF + biofertilizer, FYM + biofertilizer and 50% RDF + FYM + biofertilizers on growth, yield attributes and fruit yield bitter gourd (Momordica charantia L.) cv. Pusa vishesh. The results of the study showed that the seasonal crop evapotranspiration with maximum yield potential was 479.6 mm. Individual application of moderate frequency of irrigation at 10 day interval or 50% RDF + FYM @ 15 t/ha + bio-fertilizers recorded the highest number of vines per plant, maximum vine length, length of internodes, number of fruits per plant, fruit length, fruit girth, flesh thickness of fruit, fruit weight per plant and fruit yield. The coupling effect revealed that moderate frequency of irrigation at 10 days interval along with balanced nutrients application through 50% RDF (30:20:20 kg NPK/ha) + FYM + bio-fertilizers inoculation was found to be the best treatment combination for deriving maximum growth characters, yield augmenting parameters, fruit yield (17.79 t/ha) and moderate crop water productivity (3.71 kg/m3) which might be advocated to the resource poor farm regions. The developed predictive model on water-yield production function can serve as a good guideline for bitter gourd growers to yield potential allocation decision related to varying irrigation water supply.
