The response of bio-fertilizers (Rhizobium and phosphate solubilizing bacteria) and inorganic fertilizer application on yield and yield contributing attributes of black gram (Vigna mungo) under rain fed condition of Chitrakoot region

Abstract

A field experiment was conducted at the Nanaji agricultural research farm, faculty of agriculture, Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M.P.) to study the response of rhizobium and Phosphate solubilizing bacteria along with inorganic fertilizers on yield and yield contributing attributes of “IPU-243” variety of black gram (Vigna mungo) crop. The experiment was conducted during the kharif season of the session 2021-22 in the dryland area of Chitrakoot. The experiment was consisted of three replications along with thirteen treatments laid out in randomized block design (RBD). The treatment was composed of bio-fertilizers incorporated with inorganic fertilizers to see the difference between absolute control and combined treatments. The seed treatment was done with rhizobium and phosphate solubilizing bacteria (PSB) was given along with soil by mixing it with finely powdered farmyard manure. The yield contributing factors that were taken into account for the purpose of study was number of pods per plant, number of seed per pod, test weight, grain yield per plot and grain yield per hectare. The results indicated that treatment with 100% RDF + rhizobium + PSB showed the best results amongst all the treatment was statistically significant over control and rest all other treatments.
