Poisk Agro Holding offers domestic vegetable growers hybrids of white cabbage, allowing to organize a conveyor for the production of vegetable products. At the same time, there is a development and improvement of technologies for their growing on the basis of ARRIVG – branch of FSBSI FSCVG and close corporation Kulikovo. The technology for growing a number of hybrids was proposed to vegetable growers in 2019 using the example of close corporation Kulikovo, which allows you to get a crop at the level of the best foreign analogues. The results are presented in this article on the testing of domestic hybrids in the Moscow region on the basis of ARRIVG – branch of FSBSI FSCVG on various backgrounds of mineral nutrition: control without fertilizers, N120P120K180, N180P180K270. The soil of the experimental plot is alluvial meadow saturated soils: medium loamy, cultivated. Weather conditions during the years of research were not entirely favorable for the growth and development of white cabbage, especially in 2018, which is characterized by hot summers and low rainfall. The moisture deficit was compensated by additional watering. In 2015–2019, the following hybrids were studied: F1 Knyaginya, F1 Gertsoginya, F1 Kontinent (selection of Poisk Agro Holding); F1 Idillya, F1 Dmitrovsky (joint selection achievements of the FSCVG and Poisk Agro Holding), F1 Flagman (selection of Poisk Agro Holding and Breeding Station after N.N. Timofeev Ltd) F1 Bоmond Agro (a hybrid of Poisk Agro Holding, FSCVG and Breeding station after N.N. Timofeev Ltd). Productivity of marketable products varied against 53 to 57.3 t/ha without fertilizers; the maximum yield was observed for the F1 Bomond Agro hybrid 57.3 t/ha. Hybrids provide this yield due to their genetic potential. Productivity of marketable products ranged from 61.6 to 76.8 t/ha when fertilizers were applied at a dose of N120P120K180, yield increase was 16.23–35.21%. The maximum value was observed for the F1 Gertsoginya hybrid of 76.8 t/ha. Hybrids of F1 Idillya and F1 Gertsoginya possess the highest yield of marketable products with an increase in the rate of full mineral fertilizer to N180P180K270 – 89.3 t/ha and 84.9 t/ha, respectively. In 2019, the F1 Kontinent hybrid had the maximum yield among hybrids of – 91.2 t/ha, the increase due to the application of fertilizers was 70.79%. High productivity is explained by high morphological uniformity, a strong root system and high standard production of 100% for all variants of experience.
Key words: white cabbage, hybrid, fertilizers, fertilizer rate, yield, yield increase.
