Abstract

Effects of nitrogen, Phosphorus, and interaction of these nutrients on grain yield of CANOLA variety (Brassica napus L.), hyola 308 was studied under RAINFED conditions ( mean annual rainfall of 450 mm) in a calcareous soil (Fine loamy, Carbonatic, Hyperthermic, Typic Calciusteps). The experiment was carried out in a factorial CRB design with three replications for two years (2003-2005). The content of organic matter, available Phosphorus and Potassium in soil was 0.78%, 10 and 252 mg.kg-1, respectively. Treatments included four rates of nitrogen (0, 30, 60 and 90 Kg N ha-1) and three rates of P (0, 45 and 90 Kg P2O5 ha-1). The results showed that the effects of N, P and N*P interaction was significant on grain yield at a=1%. It can be concluded that application of N, P increase grain yield. N and P application increased significant thousands kernel weight (TKW). According to the results of this experiment, application of 90 Kg N ha-1 and 45 Kg P2O5 ha-1 for similar conditions is recommendable.
