Abstract

The Tver region is considered a region of the Central Federal District of the Russian Federation that has the largest amount of agricultural land (2,575.7 thousand ha). At the same time, the region traditionally occupies the last places in the structure and efficiency of their use, covering only 2% in the distribution of the agricultural significance of the regions from 17 entities comprising the Central Federal District. The main reasons for this condition are, first of all, the low efficiency of using farmland: in particular, only 39.3% of the arable land area is used for sowing. Consequently, the remaining area – more than 800 thousand ha – can be attributed to fallow or uncultivated lands without officially fixing their status and transferring them to other categories. To solve the tasks, in 2019, comprehensive scientific research on the development of individual techniques for growing seed crops of new varieties of long-stalked flax on fallow lands has been carried out based on the Tver State Agricultural Agricultural Academy by order of the Ministry of Agriculture of Russia. As a result of the development of separate methods for growing long-stalked flax on fallow lands, it has been found that for the optimal realization of the biological productivity potential of modern varieties, for the Tonus variety, a tank mixture of herbicides Agritox (1 l/ha) + Hunter (3 l/ha) + Sekator Turbo (0.1 l/ha) and foliar fertilizer with boron complexonate B-EDDYAK (381 g/ha) should be used in the herringbone phase and for the Nadezhda variety, Agritox (1 l/ha) + Fusilad Forte (1.5 l/ha) + Sekator Turbo (0.1 l/ha) and foliar fertilizer with zink complexonate Zn-EDDYAK (401 g/ha) should be used. The developed methods provide not only an increase in crop productivity but also an improvement in the sowing qualities of seeds of the cultivated flax varieties.
