The formation productivity of maize sowing under the application of herbicide trophy 90

The formation of productivity maize sowing hybrid Kharkovskiy 295 MV under the applications of different norms of herbicide Trophy 90 was studied. It is found that the net productivity of photosynthesis of corn and the value of yield has a tendency to increase under the applications of 2.5 l/ha herbicide Trophy 90. Application of 1.5 and 3.5 l/ha has a smallest active effect on these index productivity of maize sowing.
