Enhancement of plant growth, nodulation and yield of mungbean (Vigna radiate L.) by microbial preparations

A field experiment was conducted to study the effect of Rhizobium and PlantaStim preparations on plant growth, nodulation and yield of mungbean (Vigna radiate L.). Experimental treatments included of uninoculation control, inoculation with Rhizobium 3, Rhizobium 9 and PlantaStim preparations. The Rhizobium 3 and Rhizobium 9 preparations showed better results over control and PlantaStim. The results showed that Rhizobium 9 preparation inoculation rose plant height by 27%, root length by 77% and root dry weight by 78%. Inoculation with Rhizobium 3 preparation significantly increased the plant height, root length, shoot dry weight, root dry weight, pods length, number of nodules, number of pods per plant, number of seed per plant, number of seed per pod and 1000 seed weight of mungbean compared to control. PlantaStim preparation inoculation increased the number of pods per plant by 25%, number of seed per plant by 28% and weight of seed per plant by 34 % compared to control. It is concluded that a significant positive effect of inoculation with Rhizobium 3 and Rhizobium 9 on growth, nodulation and yield of mungbean plants compared to control and PlantaStim. | Enhancement of plant growth, nodulation and yield of mungbean (Vigna radiate L.) by microbial preparations
