Abstract
The field experiment was conducted during rabi season during 2017-18 and 2018-19 at the AICRP-LTFE project of Research Farm, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, India chosen for this study. The impact of continuous application of fertilizer and organic manure on physical properties of a Vertisol. The experiment was conducted in a randomized block design with ten treatments in four replications. The treatments viz., 50% NPK, 100% NPK, 150% NPK, 100% NPK+Hand weeding, 100% NPK+Zn, 100% NP, 100% N, 100% NPK+FYM, 100% NPK-S and Control. The response of various treatment on physical properties of soil at harvest of wheat crop were studied. The representative soil samples were collected at crop harvest from surface soil (0-15 cm) depth and analysed for soil bulk density, soil moisture content (0.33 and 15 bar), mean weight diameter and water stable aggregates. The results revealed that, the soil water retention at 0.33 and 15bar, MWD and WSA were signi
