Biofertilizer with phosphorus; a sustainable and eco-friendly approach for enhancing mungbean growth, productivity and protein content in changing climatic scenario

摘要

The current agro-climatic scenario is full of environmental hazards due to warm and harmful effects of changing climate. Therefore, the application of biofertilizers with phosphorous application is playing a key role in such a harsh conditions for enhancing legumes productivity. Low productivity of grain legumes is generally associated with reduced soil fertility and limited NSUB2/SUB-fixation. In order to assess the influence of rhizobium inoculation and phosphorus application on growth and yield of mung bean, an experiment was conducted at Agronomy Research Farm, the University of Agriculture, and Peshawar-Pakistanduring summer 2018. The experiment was laid out in randomized complete block design having three replications with Two factors i.e. seed inoculation (inoculated and un-inoculated) and phosphorus levels (20, 40, 60 and 80 kg haSUP-1/SUP). The experimental results showed that seed inoculation with rhizobium performed better than un-inoculated seed in terms of different growth and yield parameters. Rhizobium inoculation significantly enhanced leaves plantSUP-1/SUP, plant height, nodules plant, grain yield, and harvest index and protein contents up to (21 %). Regarding phosphorus levels, maximum leaves plantSUP-1/SUP, nodules plantSUP-1/SUP, plant height, grain yield, harvest index and protein contents were found superior with the application of phosphorus at the rate of 80 kg haSUP-1/SUP. From the experimental results it is concluded that seed inoculation with rhizobium and phosphorus at the rate of 80 kg haSUP-1/SUP showed prominent increase in growth and yield and therefore recommended for higher production of mung bean in the agro-climatic condition of Peshawar-Pakistan.
