Abstract
Relevance. Trace elements are of great importance in plant life. Due to their catalytic action, they allow plants to more effectively use the main elements of nutrition-solar energy, water and macronutrients — nitrogen (N), phosphorus (P) and potassium (K), which in turn has a positive effect on plant productivity and crop quality. Rape is very sensitive to the lack of boron, zinc. Trace elements are currently presented in various forms, and therefore the purpose of the research was to identify the effectiveness of boronand zinc-containing trace elements in the processing of seed material.Methods. Theobjectofstudyisspringrape(Brassicanapus) variety Yubileiny. Field experiments and studies were carried out in 2015–2017 in the Birsky district of the Republic of Bashkortostan. Tested options using micronutrient fertilizers: zinc sulfate, 21.5%; Ultramag chelate Zn, 15%; boric acid, 17.5%; Ultramag doron, 11%.Results. According to the results of studies, an increase in field germination by 6.5%, the yield of oilseeds by 37.1% and oilseeds by 1.7% when treated with Ultramag chelate Zn at a dose of 1 kg/ha was found.

Весной при физической спелости почвы провели закрытие влаги и через 3–4 дня локальным способом сеялкой ССЗ-2,1 на глубину 8–10 см с последующим прикатыванием
Summary
Ключевые слова: рапс яровой, микроудобрения, масличность, урожайность. Формирование урожайности маслосемян рапса ярового при обработке посевного материала микроудобрениями // Аграрная наука. Микроэлементы имеют большое значение в жизнедеятельности растений. Рапс очень чувствительный к недостатку бора, цинка. Микроэлементы в настоящее время представлены в различных формах, в этой связи целью исследований являлось выявление эффективности бор- и цинк-содержащих микроудобрений при обработке посевного материала. Объект исследования – рапс яровой (Brassica napus), сорт Юбилейный. Испытывали варианты с использованием микроудобрений: сульфат цинка, 21,5%; Ультрамаг хелат Zn, 15%; борная кислота, 17,5%; Ультрамаг бор, 11%. По результатам исследований установлено повышение полевой всхожести на 6,5%, урожайности маслосемян — на 37,1% и масличности семян — на 1,7% при обработке Ультрамаг хелат Zn в дозе 1 кг/га.
