Impact of different levels of nitrogen, phosphorous and sulphur on Physico-chemical properties of soil on mustard crop

Abstract

An experiment was conducted on “Effect of different level of Nitrogen, Phosphorus and Sulphur on physico-chemical properties of soil on mustard (Brassica juncea L.) Var. Varuna during rabi season 2019-2020 at the Research farm Department of Soil Science, Naini Agriculture Institute, SHUATS, PRAYAGRAJ, trial was laid out in randomized block design (RBD) with three replications on sandy loam soil (sand 70%, silt 16.50%, clay 13.50%) consisting of nine treatment. Treatment T9 (N:P:S @ 100:60:40 kg/ha) was found to be the best in all treatment combinations. Data have been recorded in pre harvested crop in different days intervals at 30, 60, 90, and 120 days. Data have been recorded in post-harvest soil for pH, EC (dsm-1), Organic carbon (%), available nitrogen (kg ha-1), available phosphorus (kg ha-1) and available sulphur (ppm) were as 7.76, 0.6, 0.76%, 258.15, 22.75 and 22.75 respectively. Soil chemical properties like EC, available nitrogen, available phosphorus, available sulphur and % organic carbon found to be significant but soil pH found to be non-significant. Data have been recorded for soil physical properties like Bulk density (Mg m-3), Particle density (Mg m-3), % pore space and water holding capacity (%) were as 1.69, 2.78, 55.85% and 45% respectively and all were found to be significant.
