Influence of technology elements on achievement the biological potential of the oat variety Korifey

Abstract

In world agriculture, the Russian Federation occupies one of the leading places among oat growing countries and it is one of the five main suppliers of oat grain to the world agricultural markets. In the Siberian region, oat is considered one of the main and important fodder-grain crops. One of the most effective and cost-effective elements of crop production is the variety. A variety that is correctly selected for agricultural technology and crop production conditions, adapted to production conditions and maximally capable of achieving its biological potential under given conditions is one of the main criteria for the success of a crop grower. The research goal is to evaluate the elements of agricultural technology and identify the most effective ones that influence on the formation of the yielding capacity of the oat variety Korifey. The field experimental research was carried out on the experimental field of the Federal Altai Scientific Center of Agro-Biotechnologies from 2020 through 2022. Related studies and processing of research findings were carried out at the Altai State Agricultural University. Field trial establishment, observations, and statistical processing of the research findings obtained were carried out in accordance with methodological guidelines. There were 12 variants altogether. Spring wheat was a preceding crop. Three-year average yield in the trial made 2.83 t ha. In the variant without any tillage, the yield made 2.5 t ha; yield gain of 0.4 t ha to 2.9 t ha was obtained in the variants with minimal tillage. The highest yields compared to the variants with minimal tillage and without tillage were obtained in the variants with deep tillage - 3.1 t ha; the advantage was 16.0% and 24%, respectively. Depending on additional elements of agricultural technology, the yields in the variants were different. The maximum yields in groups with different tillage were obtained in the variants with the application of fertilizers and plant protection products – 4; 8; 12-2.8; 2.9; and 3.4 t ha.
