Optimization of agrochemical methods of cultivation of green beans

Русский. В исследованиях на дерново-подзолистой супесчаной почве применение минеральных удобрений N30-70P40K90 увеличило урожайность бобов фасоли овощной в фазу технологической спелости на 49,8–70,8 ц/га, микроудобрений (борная кислота, молибдат аммония, жидкое комплексное удобрение для бобовых) – на 9,6–14,2 ц/га, регуляторов роста (эпин, гидрогумат, мультамин) – на 9,9–10,4 ц/га, жидкого комплексного удобрения для бобовых и эпина (совместное внесение) – на 7,8–15,6 ц/га при общей урожайности бобов в удобренных вариантах 190,5–212,2 ц/га и содержании сырого протеина 15,4–16,4 %. Оптимизация агрохимических приемов при возделывании овощной фасоли обеспечила получение чистого дохода 6,5–89,5 USD/га с рентабельностью 16–61 %.

Английский. Green beans (Phaseolus vulgaris L.) appears one of the most spread vegetable crops in the conditions of the Republic of Belarus. Receiving of high-yielding cultivars requires application of scientifically based fertilizer system. In the course of the research application of mineral fertilizers N30-70P40K90, microelements (boric acid, ammonium molybdate, liquid complex fertilizer) and growth regulators (epin, hydrohumate, mаltamin) on sod-podzolic sandy loamy soil for the growing of green beans has been evaluated. Crop yield and quality of the green beans during the phase of technological ripeness depending on application of mineral fertilizers and growth regulators in the period of 2009-2011 has been measured. Content of the main nutritive substances in seedpods and leaves of green beans, % of dry matter, has been evaluated. Economic efficiency of application of mineral fertilizers and growth regulators during green beans cultivation has been analyzed. Utilization of above mentioned agrochemical measurements increases the yield of green beans by 19.05–21.22 dt/ha and raw protein content by 15.4–16.4%. The optimization of agrochemical methods while cultivating green beans ensures the net income 6,5–89,5 USD/ha with the profitability 16–61 %.
