Abstract

The purpose of the study was to estimate the effect of sunflower and pea on the amount of productivity, protein and gluten percentage in grain. The objects of the study were 13 winter bread wheat varieties (Triticum aestivum L.) developed by the Agricultural Research Center “Donskoy”. The study was carried out in 2018-2020 on the fields of the department of winter wheat breeding and seed production. The forecrops were peas and sunflower. The study results showed that the varieties ‘Volny Don’ (6.1 t / ha), ‘Krasa Dona’ (6.1 t / ha) and ‘Lidiya’ (6.0 t / ha), when sown after peas, gave the largest yields. The varieties ‘Volny Don’ (4.9 t / ha) and ‘Polina’ (4.8 t / ha) which were sown after sunflower, showed the best productivity. The analysis of qualitative indicators established that the maximum percentage of protein and gluten in grain was identified in the varieties ‘Podarok Krymu’ (16.3%; 28.3%) and ‘Volnitsa’ (16.1%; 28.5%), which were sown after peas; and the same varieties showed good results (‘Podarok Krymu’ (16.2%; 27.4%) and ‘Volnitsa’ (15.7%; 27.8%)), when sown after sunflower.

Highlights

Grain production is the basis for the entire agricultural sector of the Russian Federation
The maximum productivity of the studied varieties when sown after peas on average was given by the varieties ‘Volny Don’ (6.1 t / ha), ‘Krasa Dona’ (6.1 t / ha) and ‘Lidiya’ (6.0 t / ha)
The study results showed that the varieties ‘Volny Don’ (6.1 t / ha), ‘Krasa Dona’ (6.1 t / ha) and ‘Lidiya’ (6.0 t / ha), when sown after peas, gave the largest yields

Summary

Introduction

Grain production is the basis for the entire agricultural sector of the Russian Federation. In winter bread wheat breeding an important direction is to improve the indicators of technological and biochemical properties of grain and maintain its high quality under various soil and climatic conditions [3,4,5,6]. The combination of these directions can ensure the development of the most productive and adaptive varieties. It is common knowledge that a variety is a basis for the production of any crop It largely determines the regional cultivation technologies, the amount of productivity, the chemical composition of grain and the energy efficiency of the obtained products [7,8]
