Influence of agrotechnical measures on seed productivity of the winter wheat varieties in the conditions of South Ukraine
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 99, Issue
Abstract
The article reflects the results of studies on the seed productivity of winter wheat varieties depending on the protection of plants and microfertilizers during cultivation in the southern Ukraine. It was established that the photosynthetic productivity of seed crops of winter wheat depended significantly on the phases of plant development, grade composition, protection schemes against pathogens and microfertilizers. The largest area of the leaf surface 42.5 thousand m2/ha was on the variant with the Konka variety in the joint protection of plants with Trichodermine and Gaupsin preparations, the introduction of microfertilizer Avatar, and on the grade Kherson 99 with the chemical protection and without the introduction of microfertilizers, this indicator decreased by 38.3%. The average daily growth in the area of the leaf surface reached its maximum in the interphase period r"enewal of vegetation – outlet into the tube."The Konka variety produced a yield of 3.59 t/ha, which is 8.2% more than the Kherson 99 variety. The use of chemical and biological protection in different ways affected the seed productivity of the crop, the most effective being the joint use of biochemicals Trichodermine and Gaupsin.
