Response of NPK, Vermicompost and FYM on Physical and chemical Properties of Soil Under Cluster Bean (Cyamopsis tetragonoloba L.)

The development and application of organic fertiliser is now regarded as an essential method in the field of soil science that is in the attention of investors worldwide due to the advancement of environmental contamination and health effects caused by the incorrect use of inorganic fertiliser. On the central research farm of the department of soil science and agricultural chemistry, (NAI) SHUATS, Prayagraj, research was carried out during the Kharif season of 2023. Field trial was designed on Randomized Block Design with three replications and nine treatments. It may be concluded from the trial that the different level of NPK, Vermicompost and FYM in the experiment gave the greatest value. The best results were resulted the greatest Pore Space, Water Holding Capacity, Electrical Conductivity, Available Nitrogen, Phosphorus and Potassium significantly in T9 [@100% NPK + @ VC 4 t ha-1 + @FYM 10 t ha-1]. In contrast, the control treatment T1 [Absolute Control] had the least results in all categories.
