Productivity of onion by using the regulator of the growth energy-m

Abstract

The effect of plant growth regulator on onion is studied. It is shown that the silicon-organic preparation Energia- M stimulates the growth and development of plants, increases the productivity of onions. The most promising for the soil and climatic conditions of the Lower Volga region are hybrids of onion, which have high adaptive capacity and significant potential yield, in combination with the optimal level of water consumption. In the field experiment, phenological observations were carried out, water consumption and biological yields were taken into account with the determination of the crop structure, the weight of the commodity fruit and the marketability. The increment of the onion yield from the Energia-M treatments ranged from 14.5% to 50.5%. At the same time, a minimal increase in yield was observed in the version where only presowing soaking of onion seeds on the Octant F1 hybrid was used. The maximum increase in yield caused the complex use of the preparation for soaking seeds and spraying plants twice in recommended doses on the Valero F1 variant.
