YIELDS OF SPRING BARLEY DEPENDING ON THE USE OF GROWTH STIMULATORS
Journal Title: Наукові доповіді НУБіП України - Year 2017, Vol 4, Issue 4
Abstract
Researched the influence of plant growth stimulants (Biolan, Biosil and Vermistim) on the grain productivity of spring barley varieties of Helios and Komandor with using them in incrustation of seeds, leaf-feeding at preplant stage and combined use. Emphasized high value of barley spring for economics. Empha-sized that further improvement of technologies should be focused on the transition to a broader use of biological means of increasing productivity. Established the effec-tiveness of plant growth promoters for barley crops, particularly through presowing seed by Biolan, Biosyn, Vermystym yield sort Helios grew respectively by 2.3; 5.7 and 8.0% and sort Commander - 3.8; 5.7 and 6.6%. Spraying the plants in the phase of tillering study drug provided a significant increase in grain - to 9.2% in Helios grade and 11.6% in sort Commander. The combined use of drugs (inlay seed + spraying in the phase of tillering) provided additional growth harvest of spring bar-ley sort Helios at 0,46-0,82 t / ha and a sort of Commander at 0,54-0,93 t / ha with compared control. Received substantial allowances, mathematically proven. Pro-posed for the improvement of agricultural technologies for greater use of biological agents to improve yields and product quality.
