OPTIMIZATION OF MINERAL FEED OF WHEAT WINTER-ANNUAL IS IN CROP ROTATIONS OF SOUTH STEPPE OF UKRAINE
Journal Title: Наукові доповіді НУБіП України - Year 2018, Vol 6, Issue 6
Abstract
The results of researches, got in the protracted field stationary experience during 46, are represented in the article. The aim of researches was determination of the productivity and quality of grain of wheat winter-annual at the different systems of fertilizer. Researches executed in the protracted field stationary experience of department of agricultural chemistry and fertility of soils of the Odessa state agricultural experimental station of NААS on the southern black soil humus wakeupinterval on the forest breed, founded in 1971. The analysis of results of the protracted field stationary experience provided the receipt of objective data of action of fertilizers on the productivity and quality of grain of wheat winter-annual and recoupment of basic elements of feed and systems of fertilizer of the productivity increases during six rotary presses of crop rotation. It is set that the protracted use on black earth south of the organic-mineral system of fertilizer provided the high productivity and the best quality of grain of wheat, content squirrel and gluten in that answered the requirements of the second class. The greatest productivity of wheat winter-annual was got then pair black and sideration, that presented according to 5,29-6,75 t/ha and 4,71-6,37 t/ha. It is marked, that stopping of top-dressing during ten years resulted in the decline of the productivity of wheat winter-annual on 13,5%, intensity of dynamics of that depended on the system of fertilizer.
