Residual effect of integrated nutrient management on growth, yield and quality of vegetable Cluster Bean

A field experiment was conducted during year 2006–2009, at Horticulture farm, college of Agriculture, Bikaner (Rajasthan) to evaluate the residual effect of organic and inorganic sources of nutrients on growth, yield and quality of vegetable cluster bean var. Pusa Navbahar. The results showed that among different growth parameters viz. average plant height (17.41cm) and leaf chlorophyll content (2.74 mg/g), were recorded maximum under vermicompost. Among different levels of organic manures, level of 21 tonnes ha-1 produced maximum plant height (20.17cm) and leaf chlorophyll content (2.49 mg/g). Among different fertilizer doses, application of 100 per cent RD produced maximum average plant height (17.26 cm) and leaf cholorophyll content (2.47 mg/g). Among yield attributing parameters, average pod length (8.40cm), pod yield per plot (2.954 kg), pod yield q/ha-1 (41.03) were recorded maximum under vermicompost. Among different levels of organic manures, level of 21 tonnes ha-1 produced maximum average pod length (8.78cm), average pod weight (8.99 g), pod yield per plot (3.039 kg), pod yield q/ha-1 (42.21). Among different fertilizer doses, maximum average pod length (8.17cm), average pod weight (7.94 g), pod yield per plot (2.983kg), pod yield q/ha-1 (41.43) were found under the treatment of 100 per cent RD. Quality parameters, viz. nitrogen content in pod (1.94%), protein content (12.12%) and fibre content (9.61%), iron content (87.86 ppm), copper content (6.81ppm) and zinc content (32.68 ppm) were recorded maximum under vermicompost. Phosphorous content (0.289%) was recorded maximum under PROM. However, potassium content showed non significant differences with respect to different sources of organic manures. Among its various levels, treatment consisting of 21 tonnes ha-1 produced maximum nitrogen content (1.96%), phosphorous content (0.279%), potassium content (0.211%), iron content (88.71 ppm), copper content (6.82 ppm), and zinc content (32.45 ppm) in pods of cluster bean
