Influence of Nitrogen and Phosphorus Application on Crop Productivity and Profitability of Gobhi Sarson (Brassica napus L.)

The field experiment was conducted at Agriculture Research Farm, RIMT University, Mandi Gobindgarh (Punjab) during the rabi season of 2023-24 to study the “Influence of nitrogen and phosphorus application on crop productivity and profitability of Gobhi sarson (Brassica napus L.)”. The experiment consisted of nine treatments combination with nitrogen and phosphorus levels. The experiment comprised of three level of nitrogen viz., (75 kg, 100 kg and 125 kg N/ha) and three levels of phosphorus viz., (20 kg, 30 kg and 40 kg P2O5/ha) were tested in Randomized Block Design (RBD) with three replications. Observation concerning growth parameters, yield attributes and seed yield of Gobhi sarson was recorded. The application of 125 kg/ha N + 40 kg/ha P2O5 treatment had the highest values for growth characteristics like plant population, plant height, number of branches/plants, chlorophyll content, yield characteristics like number of siliqua/plants, number of seed/siliqua, siliqua length (cm), test weight, grain yield, straw yield and also economically viable like net return and B:C ratio over rest of the treatments.
