Exploring the Relative Economics of Mustard Plant under Various Treatments

Abstract All the major plant nutrients viz., nitrogen, phosphorus and potassium play important role in increasing the production of mustard. A major part of fertilizer nitrogen applied is lost as NH³ through volatilization. The optimum supply of phosphorus to the plant stimulates root development and growth thereby helps to establish seedling quickly and also reduces the harmful effect of excess nitrogen in plants. Potassium helps in maintaining a normal balance between carbohydrates and proteins. Economics of each treatment in relation to fertilizers was worked out taking into account the current prices of produces, fertilizers and its expenditure involved in all kinds of operations as per treatment on per hectare basis in ha ₹-1 and the cost of cultivation is calculated where, gross returns, net returns and benefit cost ratio was considered. Economic returns were worked out by calculating operational cost of individual treatment. A field experiment was initiated during rabi, 2021-22 at Research Farm, Vivekananda Global University, Jaipur. The experiment was laid out in factorial randomized block design with three replications comprising of three fertilizer treatments viz. (F1) 0 kg ha-1, (F2) 60 kg N + 30 kg P2O5 ha-1 and (F3) 60 kg N + 30 kg P2O5 + 20 kg K2O ha-1 as first factor. On the basis of experimental finding summarized, Marked improvement in growth, yield traits and yield, quality and nutrient uptake of mustard were observed with application of (F3) 60 kg N + 30 kg P2O5 + 20 kg K2O ha-1. On the basis of B: C ratio, application of F3) 60 kg N + 30 kg P2O5 + 20 kg K2O ha-¹.
