Effect of Sulphur and Sowing Date on Soil Fertility, Growth, and Yield of Rapeseeds (Brassica napus L.)

<p><strong><span>Abstract:</span></strong><span> <span>Rapeseed (Brassica napus L.) is one of the most important oil seed crops globally, contributing significantly to edible oil production and animal fodder. The present study, conducted during the rabi season of 2022-23 at the Institute of Agriculture Training & Research, Prem Nagar, Dehradun, Uttarakhand, aimed to assess the impact of different sulfur doses and sowing dates on soil fertility, growth, and yield of rapeseed. The research evaluated key agronomic parameters, including plant height, number of leaves, seed yield, and soil nutrient status. Findings revealed that Sulphur application positively influenced crop performance, enhancing biomass production and oil content. Similarly, the optimal sowing date ensured maximum yield by mitigating temperature stress and synchronizing the reproductive phase with favorable climatic conditions. The study underscores the significance of Sulphur nutrition and appropriate sowing schedules in improving rapeseed productivity, thus contributing to sustainable agricultural practices.</span></span></p>
