In the single factoranalyzes, It shows a negative related line to Nitrogen dosage andoil-content. The relation of Phosphate dosage and oil-content is curverelated. To some extent, the using of Phosphate will raise the oil-contentof rape, but it will be lower if Phosphate is too much. The Kainite dosageand oil-content is curve related. The relation of Sulphur dosage andoil-content is related to the experiment place. The oil-content is higherwhen the Nitrogen dosage at low level, the Phosphate dosage at middle level,the Kainite dosage at middle level in this condition.
