Abstract:
The present investigation entitled, “Soil fertility, nutrient uptake and yield of soybean as influenced by various levels of phosphorus in Vertisols” was undertaken during 2019-20 at Research Farm, Department of Soil Science and Agricultural Chemistry, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra. The experiment was laid out in Randomized Block Design with five treatments randomized in four replications. Among the various treatments, the significantly higher soybean yield was recorded with the application of 30:90:30 kg N, P
