THE FERTILIZERS EFFECT ON CLEAN PRODUCTIVITY OF PHOTOSYNTHESIS OF SOYABEAN IN CONDITIONS OF DIRECT SOWING (NO-TILL)

The effect of fertilizers on clean productivity of photosynthesis of soybean in conditions of direct sowing was researched. The fertilizers rate N60P60K60has positive effect on plant growth and plant development of soybean during its vegetation. Leave index was 2.83 and maximal. The content of dry matter in plants was 5.77 t/ha and clean productivity of plant photosynthesis was 9.22 g/m2. Therefore, the soybean yield was 3.21 t per ha in variant with fertilizers rate N60P60K60. The yield surplus was 0.86 t/ha compared to control. In a variant of traditional tillage application, yield surplus was 0.44?1.07 t/ha compared to to direct sowing
