Nagirny V. Influence of sowing periods and microfertilizers on productivity of winter barley varieties in the Southern Ukraine

The object of research is the process of development of elements of agrotechnical methods of growing winter barley in the conditions of the South of Ukraine. The purpose of research is to study the reaction of new varieties of winter barley to the elements of cultivation technology, scientific substantiation and determination of practical efficiency of microfertilizer seed treatment and sowing dates of studied varieties in climate change of Southern Ukraine. Research methods - field; laboratory; statistical; computational, economic, mathematical. Research results - For theory: For the first time for the conditions of the south of Ukraine the influence of water-physical indicators of soil and efficiency of use of moisture and nutrients by plants of new grades of winter barley is investigated. For practice: As a result of research the elements of technology of cultivation of new grades of winter barley which can be recommended for arid conditions of the South of Ukraine are improved and offered to production. Scope - agricultural enterprises of southern Ukraine.
