Effect of Different Levels of Macronutrients and Rhizobium on Soil Health and Yield Attributes of Field Pea (Pisum sativum L.)

The field experiment was carried out at the central research farm in the Department of Soil Science and Chemistry, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during Rabi season 2023-24. The soil texture in the experimental region was sandy loam. The design was set up using randomized block design, with two levels of sulphur (50 and 100%), Rhizobium, and NPK (20:60:40) at different levels. The treatment T9 (@100% NPKS +@100% Rhizobium+ 100% Sulphur) gave the best results in terms of plant height, number of pods plant-1, and total Field Pea yield. It also showed a slight decrease in pH, bulk density, and particle density; however, there was a significant increase in pore space, water holding capacity, EC, organic carbon, available nitrogen, phosphorus, and potassium, as well as plant growth and yield attributes. There was no discernible difference in the growth and production of Field Pea under control. The use of Biofertilizer, as well as their blend with complete NPK and S, significantly increased the characteristics of growth and total yield attributes of Field Pea.
