To study the effect of bio-organics and varieties on the growth and yield of black gram, an experiment was conducted at the instructional farm of the Department of Agronomy, Faculty of Agriculture, AKS University, Sherganj, Satna (M.P.) during the Kharif season of 2020-21. The experiment consisted of a randomized block design having a Factorial arrangement with three replications. In this experiment, 12 treatment combinations including four levels of bio-organics and treatments were B₁- PSB 10 ml/kg seed, B₂- ZSB 10 ml/kg seed, B₃- Rhizobium10 ml/kg seed and B₄- Vermicompost @ 3 t/ ha, while three black gram varieties were tested are V₁- IPU-2-43, V₂- PU-31 and V₃- Pratap-1. During the course of the study, it was found that bio-organics and different varieties significantly affected plant height, number of branches per plant, number of pods per plant, number of grains per pod, test weight, grain & Stover yield and protein content of black gram. Higher plant height (41.01 cm) and the number of branches per plant (6.53) at the maximum crop growth stage of 60 DAS were recorded under the application of Vermicompost @ 3 t/ha in combination with black gram variety of IPU- 2-43. Similarly, it resulted in the maximum number of pods per plant (26.67), the number of grains per pod (6.33), test weight (37.43 g), grain yield (11.30 q/ha), stover yield (29.70 q/ha) and protein content (23.83 %) recorded under same treatment combination of an application of Vermicompost @ 3 t/ha in combination with black gram variety of IPU- 2-43.
