K. L. Alekseeva | N. I. Bernaz | O. A. Razin
The comparative analysis of different ways of application of the growth regulators “Obereg” and “Zavyazy” for white head cabbage has been conducted. The most effective was the double spraying by the mixed growth regulators at the stage of 6-8 leaves and the stage of the beginning of the forming of head of cabbage (400 g/ha and 60 ml/ha). The time step between the treatments is 30 days. The treatments have speeded up the stage of the industrial ripeness on 5-6 days as compared to control and have increased yield of cabbage. The increasing of the content of dry atter up to 1%, sugars up to 0.5%, nd vitamin C up to 1.9% mg% was recorded. The nitrate content in all variants was in range of the maximum permissible concentration.
