Abstract
The article presents research on improving the elements of agricultural technology for the production of oilseed flax seeds and the selection of highly productive varieties of culture for the region. The experiments were conducted under the conditions of Ryazan oblast, on gray forest soil, in 2016–2019. It was established that oil flax sown on the first term of sowing in the first 10 days of May showed high productivity under the conditions of the southern part of the Non-Chernozem Earth Zone of Russia. This pattern was observed in all studied varieties of culture. The highest productivity was noted in 2016 for all studied flax varieties; maximum yield can be traced for the Istok variety in sowing time I (26.3 с/ ha). The maximum average yield for the Istok variety, according to the years of research, was 22.1 с/ha in sowing time I and 9.6 с/ha in sowing time II. Higher oil content was noted in the seeds obtained during sowing in the first 10 days of May for the VNIIMK-620, Istok, and Santin varieties and for the LM-98 variety sowing during the second 10 days of May. In the experiment, the Istok variety was late ripening, the average vegetation period was 126 days (sowing time I) and 118–119 days (sowing time II), while this index was 115 and 111 days, respectively, for the VNIIMK-620 variety.
