| Abstract | ||||
| A field experiment was conducted on a sandy soil at Ismailia Agric. Res. Station, during the winter season of 2009/2010 to study the effect of phosphorus at the rates of 0, 30 and 60 kg P2O5/fed, sulphur (0, 150 and 300 kg S/fed) and zinc (0, 10 and 20 kg ZnSO4.7H2O/fed) as well as their interactions on canola yield (Serw 4 cv.), its components (i.e., plant height, number of branches plant-1, dry matter weight of shoots plant-1 at early flowering stage, number of pods plant-1 and 1000 seeds weight) and seed quality parameters (i.e., seed oil and protein contents). In general, the obtained results reveal that the application of phosphorus, sulphur and zinc as solely treatments at the different added rates display an effective role on increasing dry matter weight of shoots at early flowering stage, nutrient contents of plant tissues at 90 days after sowing, seed yield and its quality. However, applying such nutrient treatments (i.e., P, S and Zn) showed significant increases for canola yield and its components, which their values were maximized with increasing the applied rates up to the highest ones for each nutrient, with superiority for applied P treatment as compared to either S or Zn as a solely one. The application of the combined treatments, i.e., (P x S), (P x Zn) and (S x Zn) exhibited more pronounced increases for canola seed yield and its components, with significantly differences as compared to such solely ones. These increases were maximized in case of the triple treatments of P in combination with S and Zn as compared to the applied combined couple ones. Also, increasing the applied rates of P, S and Zn significantly increased the contents of N, P and S in canola plant tissues at 90 days after sowing. Meanwhile, Zn content in the plant tissues tended to decrease with the applied P, the reverse was true for both applied S and Zn that resulted in a significantly increased for Zn-content of plant tissues. The triple combination of P, S and Zn showed a synergistic relationship between them as well as the triple combined treatment 60, 300 and 20 kg fed-1 for P, S and ZnSO4, respectively, was the most appropriate one for canola nutrition. Under the current experiment conditions, it could be concluded that the applied P, S and Zn as solely treatments showed a beneficial effect on canola seed quality parameters, where seed oil and protein contents exhibited significantly increases, and in turn in case of the combined treatments. Actually, the applied triple combined treatment of P60 S300 Zn20 was optimal for obtaining the highest values in canola seed quality parameters, i.e., greatest seed oil and protein contents. | ||||
