Photosynthetic productivity of winter wheat cultivated using No-till technology

Abstract

The article presents studies of photosynthetic productivity of winter wheat plants cultivated using No-till technology and traditional technology, conducted in 2016-2019 at the North Caucasus Federal research agricultural center. As a result of research, it was found that the cultivation of winter wheat using No-till technology contributes to the formation of a more developed photosynthetic apparatus with a high content of photosynthetic pigments ( on average, 36.9% higher than in plants grown using traditional technology), while a higher concentration of chlorophyll is preserved at later stages of plant development, which indicates a longer operation of the photosynthetic apparatus, this is confirmed by the value of the chlorophyll photosynthetic potential (CFS is 9.2% higher, than crops according to the traditional technology). A high level of mineral nutrition with the use of No-till technology reduces the load on the photosynthetic apparatus, and the net productivity of photosynthesis is 7.8 % lower than with traditional technology. An increase in the photosynthetic productivity of winter wheat plants cultivated using No-till technology ultimately leads to an increase in yield, on average over three years by 14.4% compared to traditional technology applications.
