The field experiment was conducted during Rabi, 2018 in randomized block design on clayey soils to
study the effect of organic manures and inorganic phosphorus fertilizers on available nutrient status of soil
under chickpea (variety JG-11) cultivation. Application of 100% RDP through BGD + Microbial Consortium
significantly increased the availability of nitrogen, phosphorus content of the soil. However, there was no
significant increase in the availability of potassium, sulphur, iron, copper and manganese. The availability of
zinc increased significantly at all the stages of the crop.
