Improving the productivity of onions by adjusting the elements of cultivation technology

The article deals with the influence of growth regulators used as foliar feeding on the production of high-quality products of commercial onions-turnips of Mars and candy F1 hybrids grown on irrigation in the conditions of Veselovsky Rostov region. It was determined that the highest yield of finished products per 1 thousand m2 of leaf area and 1 thousand units of FSF is observed in the treatment of plants and a hybrid of candy and a hybrid of Mars with Novosil – 3,9-4,1 t and 45,0-47,0 kg, respectively, under the influence of which the highest rates of NPF – 8,5-8,7 g/m2 per day are noted. A little more effective effect of the drug on the growth processes observed on the hybrid candy. Installed that application in technology of cultivation foliar application Novosela and Immunotsitofit allows to obtain for the hybrids and Mars candy harvest at the level of 49.0-50.1 per t/ha, to reduce the consumption of supplementary irrigation water per unit of production, improve the quality of marketable onions turnips and their safety during the long winter storage.
