Effect of Microbial Inoculants on Crop Growth, Yield, Biochemical and Phyiological Parameters of Blackgram [Vigna mungo (L.) Hepper]

A field experiment was carried out in randomized block design with 10 treatments and 3 replications at the Department of Seed Science and Technology, S.V. Agricultural College, Tirupati during 2022. The blackgram variety TBG-104 differed for field, biochemical, and physiological parameters in response to different treatments of microbial inoculants. The influence of the treatments in the field was significant with respect to crop growth, phenological and yield parameters, seed quality attributes, biochemical and physiological parameters. In case of crop growth parameters which include field emergence (%), plant height (cm) highest performance was seen in T9(91.67%,27.47cm) over control and other treatments. While all the treatments recorded values that are at par with the highest performed treatment. In case of phenological parameters which include days to first flowering, 50% flowering and maturity, The treatment T9 and T8 were the best performed over the other treatments and control. Similar trend was observed with respect to yield and yield parameters where T9(929.63 kg/ha) treatment showed the highest performance. Our results revealed that that the co-inoculation of 4 or 5 microbial inoculants showed better results over individual treatments during the period of storage.
