Abstract

The intensive development of the assimilation apparatus of spring wheat in the tillering phase ensured the accumulation of the amount of plant biomass - up to 19.6 thousand m2/ha. During this period, the development of wheat vegetation index was an average of 0.184-0.471 units. The large deviation of the NDVI index during this period shows the need to pay attention to the adoption of an optimal decision to combat weed vegetation. The intensive development of the leaf surface of wheat to the headingflowering phase ensured a large accumulation of the leaf surface of plants - up to 35.11 thousand m 2/ha and the net productivity of photosynthesis reached 8.1 g/m2 per day, accordingly, the vegetation index increased to 0.74 units, coverage of green mass of wheat amounted to more than 86.4%.The optimal soil and climatic conditions during the study period provided from 35.38 to 77.42 kg/ha of spring soft wheat grain yield, the deviation of the yield between experimental plots was up to 204%. Uneven field ripening (deviation of the vegetation index (NDVI) - 0.12) and the number of harvests up to - 2.75 c/ha show
the images obtained from the remote sensing data (RSD) and the vegetation index (NDVI) of ground-based observations.
