Effect of nitrogen, sulphur and boron fertilization on growth, yield and quality of canola

Abstract: A field experiment was conducted on sandy soil at Ismailia Agric. Res.Station, Egypt, to study the effect of either the separate application of nitrogen (60 kg/fed), sulphur (500 kg/fed) and boron (0.5 kg/fed) fertilizers or their combined application on plant growth, seed and stover yields, yield components and chemical composition of grain and stover.
Generally, it could be cocluded from the present investigation that individual application of nitrogen, sulphur and boron caused a 36, 22 and 6.5% increase in seed yield, respectively over control. At the same time, the application of nitrogen in combination with sulphur and boron showed a more pronounced effect in increasing crop yield and its components when compared with control. This treatment recorded the highest seed yield of 0.84 ton/fed. (50% increase over control) and was significantly superior to other treatments. The increase in seed yield was mainly due to the increase in capsule number/plant, number of seed/capsule and test weight of seed. As for seed quality of canola, it was also found that protein content was increased by both N and s application. Oil content was decreased slightly by nitrogen application but increased with addition of sulphur and boron. Seed protein and oil content were significantly increased by a combination N and B increased oil content and decreased protein content. Also, application of N decreased S content of seed and stover in the absence of applied S, but increased it when S was applied. application of S or B did not affect P and K content of both grain and stover significantly. P concentration in seed and stover decreased whereas K content increased with application of nitrogen
