Effect of the next-generation stimulants on the yielding capacity of winter wheat in moisture deficit conditions

In the conditions of Stavropol Krai arid region single nutrient fertilizer treatment winter wheat does not always justify costs expended due to moisture deficit during growing season. this regard, one current promising areas is additional combined use chemical fertilizers, growth-stimulating agents and micronutrients intended for seed vegetative plant treatment. 2018–2020 a research was conducted into effect VL 77 growth stimulants Orakul Semena, Multikompleks, Sera Activ micronutrient complexes at different development stages cultivation in volatile weather region. The establishes effectiveness next-generation on chestnut soils highest yield Idilliya variety (4.68 t/ha) achieved by initially dressing seeds with Semena complex treating combination Multikompleks spring resumption period. second plants flag leaf stage stimulated their growth, but reduced yields 2.3%. Still, obtained exceeded test 4.3%. On average, three years stimulant boosted yielding capacity 4.6–5.1%. cost concurrently increased from 66.0% 89.0%.
