Nitrogen content and uptake in leaves and stem of common bean (Phaseolus vulgaris L.) as influenced by application of various biofertilizers with different levels of phosphorus under intercropping system

The present study was conducted during kharif seasons of 2012 and 2013 at the Krishi Vigyan Kendra (KVK) of Shere-e-Kashmir University of Agricultural Sciences and Technology, Budgam, Jammu and Kashmir. The climate of the experimental site was temperate with mild summers and cold winters, showing wide variations in mean maximum and minimum temperatures. Common bean variety “Shalimar Rajmash-1” was used for the present study. The experiment was laid out in a complete randomized design (CRD) with each treatment replicated three times. Different levels of DAP (20 and 40 kg) along with different biofertilizer combinations like Rhizobium (Rhizobium leguminosarum), Azotobacter (Azotobacter vinelandi), VAM (Glomus mosseae) have been used during the research. The results of the experiment revealed that the nutrient content and uptake in leaves and stem of all the inoculated common bean plants was higher as compared to control plants. Rhizobium + VAM @ 20 kg P/ha in the present research showed significant impact on nitrogen content in leaves and stem of common bean as compared to all treatments. Significant increase in nitrogen uptake was recorded when plants were inoculated with Rhizobium + VAM @ 20 kg P/ha. Overall the significant increase in nitrogen content and uptake of common bean was due to positive interactions among different microorganisms leading to healthy and vigorously growing plants.
