BIOLOGICAL FEATURES OF HYBRID FORMS OF CABBAGE IN THE RYAZAN REGION
The cultivation of cabbage goes to a new level. From year to year, the acreage of this vegetable decreases on an industrial scale, but the gross harvest remains the same. This indicates high-tech agricultural technology, including new irrigation systems, plant protection products and high-quality planting material. However, despite good harvests, the share of imports is still quite high and falls mainly in January-April. This indicates shortcomings or violations of storage technologies, or poor-quality material laid. In this regard, the purpose of the article is to study some phenological phases of seedlings that affect the safety of cabbage To achieve the goal, the following tasks were set: to study the phenological phases of development of cabbage and the influence of planting time on the formation of the head, to study the influence of planting time on the maturity of heads of hybrid cabbage form Aggressor F1 for storage.
