The effects of planting transgenic soybean on the yield, quality and other agronomic traits were determined. No marked differences on yield were found between the succeeding crops planted on field where transgenic soybean were planted in the previously year and those planted on field where non-transgenic control soybean were planted in the last year. In parallel with this similarity, dry mass accumulation of wheat and maize showed no differences for those crops growing on the two different fields. The height, spike length and the gluten content of wheat planted on the two different fields were also investigated and no difference was found. In addition, the sugar content of beet was not affected by planting them on field where transgenic soybean was previously planted.
