Abstract
A pot experiment with acid yellow-brown soil was conducted to assess the interactive effects of molybdenum (Mo) and phosphorus (P) fertilizers on the grain yield and quality of Brassica napus which is sensitive to soil P and Mo deficiencies. Both Mo and P fertilizers were applied at three levels (0, 0.15, and 0.30 mg Mo kg -1 soil; 0, 80, and 160 mg P kg -1 soil). The results indicated that application of P fertilizer increased grain and oil yields in the absence or presence of Mo fertilizer, while Mo fertilizer application increased the two parameters only in the presence of P fertilizer. P impacted grain yield mainly through increasing branches and pods of each plant while Mo through increasing pods for each plant. Oil contents, oleic and linoleic acid contents, and Mo concentrations in seeds were increased while glucosinolates and stearic acid contents were decreased by application of Mo fertilizer. P fertilizer application resulted in increases in linoleic acid contents and decreases in erucic acid contents and Mo concentrations in seeds. The highest grain yield and best quality were observed in the treatments of Mo and P fertilizers co-application, indicating a synergetic effect on grain yield and quality of Brassica napus between Mo and P fertilizers. The results obtained in this study suggest that co-application of Mo and P fertilizers is conducive for the improvement of grain yield and quality of Brassica napus.
