Influence of methods of basic tillage on the yield of spring barley varieties in the zone of influence of field-protective plantations

Abstract

The article discusses the results of studies on the study of modern released varieties of spring barley in the conditions of an agroforestry landscape and their response to various methods of basic tillage. It was found that in years with different climatic characteristics, there are differences in varieties in the duration of phenological phases. The longest vegetation was observed in the Bulat variety, and the shortest in the Prairie variety. The best results in terms of germination and preservation of plants were obtained in the variant with the Bulat variety, while in all varieties it was noted that these indicators were higher in the forested area than in the agrolandscape without forest belts. Analysis of the productivity of varieties showed that the studied varieties had different yields depending on the methods of tillage and the type of agricultural landscape. On the reclaimed territory and without protective plantings, the Bulat variety can be distinguished. The yield of this variety was the highest in all studied tillage options compared to other varieties. In the variant with flat-cut tillage to a depth of 0.25-0.27 m, it amounted to 2.63 t/ha under the conditions of the agricultural landscape without forest belts, and 2.89 t/ha under the protection of forest belts. Thus, it can be recommended for agricultural producers to cultivate the Bulat variety, and to carry out the main processing of light chestnut soil with a tool with flat-cutting working bodies to a depth of 0.25-0.27 m.
