Investigation of the effect of a biological stimulator on morphometric indicators and yield data of winter wheat and spring barley

The aim of the research was to study the effect of the new biological agent Nigor ++ on the morphometric parameters and structure of the yield of winter wheat and spring barley under the conditions of a semi-production experiment. The work was carried out in the conditions of the Research and Educational Production Center "Integration" of the Orel State Agrarian University named after N.V. Parakhin in the conditions of semi-production experiments on winter wheat Moskovskaya 39 and spring barley Ataman. The influence of a new biological preparation with a protective and stimulating property with the working name Nigor ++ on the yield data of winter wheat Moskovskaya 39 and spring barley Ataman was studied. It was found that the biostimulator treatment of grain plants during the tillering and earing phase has a positive effect on morphometric indicators and yield data, regardless of whether the plants belong to different species and forms. The biostimulator Nigor++ promotes greater accumulation of biomass, plant height in both crops, and root length. The root mass under the influence of a stimulant in winter wheat increased by 11.36%, and in spring barley by 2.44%. The leaf area of winter wheat under the influence of Nigor++ increased by 21.26%, and in spring barley - by 16.64%. The number of assimilates increased in spring barley - by 36.12% and slightly less in winter wheat. The established fact of an increase in the water content of leaves in both cereals (in winter wheat by 15.31%, and in spring barley - by 5.77%) is very important. Morphometric indicators were reflected in an increase in the yield of grain crops by 8.4 - 9.1%. It is due to an increase in the mass of ears and the number of grains in the ear. The work was carried out by order of the Ministry of Agriculture of the Russian Federation R&D No. 121091400023-3 dated 14.09.2021.
