EFFECT OF PHOSPHORUS AND PHOSPHATE SOLUBILIZING MICROORGANISM ON GROWTH AND YIELD OF BLACKGRAM (VIGNA MUNGO L.) UNDER THE ALFISOLS OF TELANGANA INDIA

A field experiment was conducted at the farmer's field in Nakrekal Village of Nalgonda district of Telangana state during the period of December 2020 to March 2021 to make a study on "Effect of Phosphorus and Phosphate Solubilizing Microorganism on Growth and Yield of Blackgram [Vigna mungo L.] under the Alfisols of Telangana".In this field experiment with 12 treatments and three replications, the experiment was designed using Randomized Block Design (RBD).The study found that varied doses of fertiliser had a significant impact on plant growth, yield attributes, and quality parameters such as protein content, nutrient availability in soil after harvest of blackgram.The crop growth attributes such as plant height, number of leaves plant -1 and number of branches plant -1 were significantly influenced by its application.The highest seed yield of 1161.33 kg ha -1 and stover yield of 2495.24kg ha -1 was recorded with the treatment of 50 Kg P 2 O 5 ha -1 + PSM and was significantly superior over all the other treatments.The highest nutrient content was also recorded with the treatment of 50 Kg P 2 O 5 ha -1 + PSM.The available nutrient in soil was also found to be significantly improved with the application of treatment 50 Kg P 2 O 5 ha -1 + PSM.
