Abstract: An experiment was conducted during winter 2012 at Department of Horticulture, Faculty of Agriculture, Annamalai University, Tamil Nadu. The Experiment was conducted in Randomized Block Design (RBD) with 12 treatments and 3 replications in the inorganic (NPK) and organic (vermicompost) were allotted to 7 different combinations of biofertilzers (Rhizobium + Pseudomonas fluorescence) and micronutrients (Zn and Fe). Results showed super imposition of 25% N organic (recommended dose of N through vermicompost) to 100% NPK (recommended dose of NPK through fertilizers), being at par with 100% NPK + 50% N organic resulted in significant improvement in growth character, plant height, branches plant^-1, and yield attributes (pod length, pods plant ^-1 and grains pod^-1) and nutrient (N, P, K, S, Zn and Fe) uptake was higher under 100% NPK + 25% N organic level. The combined effect of biofertilizers and micronutrients (biofertilizer + Zn + Fe treatment) was significantly better than their individual effects as this treatment significantly improved growth characters, yield attributes and integration of 100% NPK +25% N organic and biofertilizer + Zn + Fe was conducive for getting significantly optimum yield.
