Agrochemical methods for increasing the yield of root chicory

Relevance. The effectiveness of fertilizers depends on the need plants for nutrients and ability soil to meet this need. According Research Institute Raw Materials Alcohol Industry, responsiveness chicory individual substances changes dramatically during growing season. In first period its development, responds sharply positively only phosphorus. future, phosphorus efficiency remains stable two months by end season, attenuation begins. potash efficiency, contrary, is low in months, contrast action phosphorus, it gives a sharp rise. nitrogen season occupies an average position between potassium. Methodology. aim research was identify most effective doses macro- microelements methods their application (basic top dressing) ensure maximum yields root crops. experiments were carried out Nonchernozem zone Russian Federation Rostov district Yaroslavl region experimental field station chicory¬ – branch FSBSI FSVC. Results. As result conducted studies, found that increase dose nutrition against background phosphorus-potassium fertilizer increased yield crops, fractional mineral more compared main application, introduction boron cobalt content inulin sugars as increased.
