Abstract
The effectiveness the use of new nutrient complexes is studied. It is set that a combination of nutrient complexes with organic and organicmineral nutrition background promotes to good growth and development of plants during the growing season, provides the best parameters of crop yield structure and the crop yield and economic efficiency of spring barley cultivation in the condition of the Eastern Steppe of Ukraine.
Highlights
Throughout its humankind history has sought to improvement of agricultural production, including plant growing
We studied the effect of new nutrient complexes with using three of backgrounds nutrition by grown variety Shidniy spring barley
On the mineral nutrition background best biometric parameters were obtained with biological crop protection and new nutrient complexes
Summary
Throughout its humankind history has sought to improvement of agricultural production, including plant growing. The purpose of the improvement was possibility of obtaining more of products from a smaller area of farmland. Starting with the second half of the twentieth century, the agricultural producers began intensive use of fertilizers. This allowed access to intensive grain production. The use of fertilizers contributed to increasing crop yield by 20–25% (Бурбела 1995). The balance of nutrients in the soil was maintained through industrially produced agrochemicals
