A field experiment was conducted during kharif season (2016) to study the “Effect of different level of N P K and Gypsum on Soil properties and yield of Groundnut var. Jyoti (Arachis hypogaea L.)” at the research farm of department of Soil Science and Agricultural Chemistry Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad, Experiment laid out in randomized block design with three levels of N P K [0% N P K = No application of N P K, 50% N P K = (10:30:20kg ha-1), 100% N P K = (20:60:40kg ha-1)] and three levels of Gypsum [0% Gypsum = No application of Gypsum, 50% Gypsum = (250kg ha-1), 100% Gypsum = (500kg ha-1)].The result shows that application of different levels combination of N P K fertilizers increased growth and yield of groundnut. It was recorded from the application of chemical fertilizers in treatment T7 [(@ 100% N P &K + 50%. Gypsum)] increased pH 7.37, EC 0.714 dS m-1, Organic carbon 0.79%.Whereas available Nitrogen, Phosphorus, Potassium, Sulphur and Calcium were found more in T8 [(@ 100% N P K + 100% Gypsum)], followed by T7 [(@ 100% N P K + 50%. Gypsum) EC decreased. The physical parameters of soil such as bulk density g/cc, particle density g/cc and pore spaces % increased. It was also concluded from trail that the application of fertilizers in treatment T8 [(@ 100% N P K + 100% Gypsum)] was found in increasing Plant height, No. of leaves per plant, No. of branch, length of pod (cm), number of grain per pod, seed index (g.plot-1) and grain yield and as well as yield.
