Abstract
At the “Central Research Farm, Soil Science and Agricultural Chemistry Department, SHUATS, Prayagraj”, an experiment titled "Impact of various levels of Nitrogen, Potassium, Phosphorus and Biochar on Soil Physico-chemical Properties and Yield of Black gram(Vigna mungo L.)Var: Shekhar-2" was carried out during the Zaid season of 2023–2024. A randomized block design was used, consisting of three variables and three levels of NPK (at 0, 50, and 100% ha-1) and biochar (at 0, 50, and 100% ha-1). An excavated soil specimen from the experimental site prior to the start of study activities showed that the soil had a sandy loam texture, a neutral to alkaline reaction, and significantly higher treatment levels.
