Abstract
A field experiment was carried to study the effect of fertilizations on growth,yield and econo-mic efficiency of spring oilseed rape.Under the application of nitrogen,phosphorous,potassium,organic fertilizer,boron and sulfur fertilizers to the field,the seedling biomass of root and shoot,effective branch,siliqua,yields of rapeseed seed and net income of the spring oilseed rape can be increased to33.5%-34.4%,14.3%-133.0%,18.9%-32.8%,13.1%-27%,6.7%-29.9% respectively.The value was higher than those in the treatment with only application of nitrogen and phosphorous fertilizers.Nitrogen and phosphorous fertilizers incorporated with potassium,boron and sulfur,organic fertilizer markedly improved the yield of rapeseed seed and net income of farmers in Qinghai.
