It was studied that effects on three kinds of large amount elements (N .P .K), three kinds of middle amountelements (Ca .Mg .S)and six kinds of minor amount elements (B .Mo .Zn .Fe .Na .Cl)to the protein and oil contentsof the high protein content variety Dongnong 42 and the high oil contents variety Dongnong 163 .The results showed thatthe protein content of high protein content variety could be increased 1 .34 percentage and of high oil content variety couldbe increased 1 .44 percentage for using S .Applying Zn could make the protein content of high protein content soybean increase1 .07 percentage .The protein content of high oil content variety could be increased 2 .19 percentage when the B ,Mo , Zn were applied at the same treatment .N , P ,K could make significant effects on oil content of soybean .Using Kcould make oil content increase 1 .57 percentage , it was significant at level 0 .01 than CK .Oil content in treatment of P-K could be increased 1 .2 percentage , in treatment of N -K could be increased 1 .52 percentage and in N -P could beincreased 1 .11 %.The Ca ,Mo were valued for the increase of oil content of soybean .The using of fertilizer maybe havegreat value for the decrease of plant height and the increase of weight of harvest , pods and seeds .Particularly , the treatmentof N -K had significant effect on the plant height ,weight of harvest and yields .It was seemingly that Na ,Cl , Fe hadpositive effects on the protein content .The effect of Na was the most distinct , it made two varieties increase 2 .08 and 1 .85 percentage in the experiment .Cl made two varieties increase 1 .26 and 1 .65 percentage and Fe made two varieties increase1 .11 and 1 .43 percentage in the experiment.
