INTEGRATED NUTRIENT MANAGEMENT IN MUNGBEAN (VIGNA RADIATA L.) THROUGH NPK AND BIOFERTILIZERS

Abstract

To study the effect of nutrient management in mungbean through NPK and bio-fertilizers, a field experiment was carried out during 2016 and 2017. The treatments contained along and combinations and two levels of control viz. control without rhizobium (T1) + Control with rhizobium (T2) with 3 replications in factorial RBD. Results indicated that application of treatment T8 (RII-4+NC) significantly increased the plant height (27.30 cm), primary branches (3.67), effective pods plant-1 (18.00), number of leaves per plant (8.33), 1000-grain wt. (36.31 g), seed and stover yield (13.05 and 30.93 q ha-1), nitrogen uptake (root 100.80 and shoot 159.04 g kg-1), phosphorus uptake (root 1.04 and shoot 1.14 g kg-1) and K uptake (root 58.15 and shoot 185.24 g kg-1) and growth parameters like dry weight of root (0.65 gm) dry weight of shoot (6.76 g). Application of T1 (Control without rhizobium) significantly and linearly decreased the growth parameters such as plant height (26.30 cm), number of leaves per plant (6.67), number of branch per plant (2.67) and number of pods per plant (13.67), seed weight of 1000 grains (33.24 g), seed yield (12.09 q ha-1), stover yield (23.21 qha-1 ). Combination treatments T6 (R I – 3 + RIII -4), T9 (RIII– 4 + NC-1) and T10 (RIII– 4 + NC-9) also showed significant response to all the parameters and showed better response.
