Influence of Organic Nutrient Sources on Yield and Economics of Vegetable Cluster Bean (Cyamopsis tetragonoloba (L.) Taub.) Variety – MDU1

Cluster bean is one of the important industrial legume crop, favoured semi-arid and arid farmers by its drought tolerance nitrogen fixation capacity. A investigation was carried out to study impact various organic nutrient sources on yield economics vegetable cluster bean. The experiment conducted in randomized complete block design with 12 treatments three replications at wetland farms, Agricultural College Research Institute, Tamil Nadu University, Coimbatore, during Kharif season, 2018. parameters were recorded after each picking from five tagged plants averaged for statistical analysis. net plot area noted. harvest index, gross returns, returns benefit-cost ratio calculated treatment. Significantly higher pod length, weight, yield, index (11.6 cm, 2.4 g, 11084 kg/ha, 2.4, Rs. 1,66,254/ha, respectively) under recommended dose fertilizer (50:50:40-N:P:K) addition foliar spray TNAU pulse wonder. However, all these statistically par such as farmer’s practice 25 t/ha Farm yard manure (FYM) along a 3% Panchagavya. But humic acid @ 6 l/ha banana pseudostem sap 2% followed Humic Panchagavya practice. Considering safer environment, human health economic feasibility applying FYM 10 Jeevamruth 500l/ha found provide yields profits
