The results of research on increasing resistance of winter wheat varieties of different geographical origins to adverse weather conditions in the zone of unstable moistening in the North-Eastern Forest Steppe of Ukraine have been summarized. Rational use of agrometeorological resources made it possible to determine optimal terms of work on the elements of cultivation technology, taking into account weather conditions of the current year nd on their basis, to improve adaptive technologies for growing winter wheat varieties. This contributed to increase of yielding capacity, quality of grain and sustainability of agriculture. Such conditions were favorable for winter wheat crops of late sowing periods, the plants of which reached tillering phase on a significant part already in winter period. Yielding capacity of winter wheat by sowing dates (on average by varieties) was: September 1 – 5.72 t ha-1, September 10 – 5.54 t ha-1, September 20 – 5.41 t ha-1, October 1 – 5.45 t ha-1, October 10 – 4.87 t ha-1, October 20 – 5.11 t ha-1, November 1 – 5.06 t ha-1. Kraevyd and Pylypivka were the most productive among winter wheat varieties under conditions of 2020. Their yielding capacity varied between 6.18–6.88 t ha-1 and 5.53–6.30 t ha-1 depending on sowing dates. The highest level of profitability was provided by Kraevyd variety (120.0–131.2%) at late sowing dates (October 1 – November 1).
The article presents the question of the effect of the effectiveness of various elements of cultivation technologies on the competitiveness of Camelina sativa and the profitability of its cultivation on acidic, low–fertility sod-podzolic soils. Fertilizers are one of the fast-acting and effective factors in increasing the yield of Camelina sativa. It was established that introduction of mineral fertilizers had a significant impact on competitiveness of Camelina sativa seeds. Dependence of productivity elements and yielding capacity on crops has been determined. It was established that spring cruciferous crops had different seed productivity. According to the results of conducted research, it was found that the highest seed yielding capacity among spring cruciferous crops had spring Brassica napus L., but the oil content in Camelina sativa seeds was 46.53%, which is 4.08% more than in Brassica napus L. Therefore, oil outcome from the yield of Brassica napus L. and Camelina sativa was almost the same.
