Effect of integrated use of molybdenum, vermicompost and combined inoculation of biofertilizers on yield and uptake of nutrients of Mungbean (Vigna radiata L. Wilzeck)

Abstract

A field experiment was conducted for three consecutive years to evaluate the effect of integrated use of molybdenum, vermicompost and inoculation of bio-fertilizers. In order to harness the maximum benefits the mung seeds were subjected to inoculation by rhizobium, PSB and PGPR. Three levels of molybdenum 01 and 2 kg MO ha-1 and three levels of vermicompost 0, 2.5 and 5.0 t V.C ha-1 were applied as treatments. All eighteen-treatment combinations were applied in Randomized block design with two replications. Three years pooled data revealed that the seed yield of mungbean significantly increased with the application of Mo and vermicompost with inoculation of biofertilizers. The increase in yield was 3.19 q ha-1, 1.21 q ha-1 and 2.34 q ha-1 due to biofertilizer, molybdenum and vermicompost application, respectively. The interactive effects of biofertilizers and vermicompost were found significant. The application of 2.5 t ha-1 vermicompost with biofertilizer was significantly higher than the application of vermicompost without biofertlizers and was at par with higher level of vermicompost application. The B:C ratio due to 2.5 t vc ha-1 with inoculation of biofertilizer was 2.61. Application of 1kg Mo ha-1 and 2.5 t ha-1 vermicompost were statistically superior over control and at par with higher level of nutrients application. The uptake of N, P, K and Mo were found significantly higher over control.
