Abstract

The methods of increasing productivity of sunflower hybrids using fertilizers and a micronutrient mixture Agromineral in the forest-steppe of the Middle Volga were described. The results of 2017–2018 studies are presented. The leaf area, the photosynthetic potential, the crop structure and the yield at different doses of fertilizers were assessed. The maximum value of the photosynthetic potential is formed by crops of the mid-season hybrid 8H477KLDM (4.386 million m2/ha per day). The use of fertilizers and micronutrient mixtures increases the photosynthetic potential and productivity by 9.09 ... 9.36 c/ha with an absolute value of 29.46 ... 31.83 c/ha.

Highlights

In Russia, the main oilseed crop is sunflower which is determined by climatic conditions, peculiarities of the raw material and production base, and consumption traditions
The yield per unit area is determined by the number of plants and the mass of one plant
Safety of crops is the most important indicator that directly affects the size of the future crop

Summary

Introduction

In Russia, the main oilseed crop is sunflower which is determined by climatic conditions, peculiarities of the raw material and production base, and consumption traditions. The area of sunflower crops is 7.3 million hectares. The demand for this crop has always been and remains high. One of the main factors increasing the economic potential of sunflower is the widespread use of highly productive varieties and hybrids and improvement of cultivation technologies [1, 2]. The main advantage of sunflower is oil. The oil is of high quality, usually sold in the world market at a higher price compared to soybean, rapeseed, cotton and peanut. Confectionery and bakery products are enriched with sunflower seeds ; they are used in the production of animal feed as a protein component [3, 4]
