The mains physiological indexes which were followed through the present research were: the leaf area at the soya plants as well the determination of azote and phosphorus from the plant. In the conditions in which the plants are treated with differentially nutritional solutions, it is observed that both in the transgenic plants case and in the intransgenic one the leaf surface in higer at the variants with complete nutritional solution than with the solution without azote or without phosphorus, and the quantity of azote, in plants increases in the same conditions. The phosphory from the plants increases both at the plants treated with complete solution and incomplete thanks to the fact that the phosphorus is easily accessible to the plants in the both conditions.
