Methods of researches are the field researches with the use of such methods - calculation, visual, instrumentation gravimetric, chemical, matematiko-statistichney. The purpose of work consists in a scientific ground and perfection of technology of growing of corn on grain by complex combination of chemical and agrotechnical measures of fight against weeds, optimization of the system of fertilizer and till of soil and determination of their influence on the productivity and efficiency of growing of this culture in the conditions of western Forest-steppe of Ukraine. Technology of growing of corn on grain with the leadthrough of doschodovogo and pislyaschodovogo harrowing, richleny sowing on a depth 6-8 and 4-5 see in a phase 6-7 leaves in complex combination with preparation of Milagro of 040SC(1,25 л/hectare) provide the productivity of grain of 8,35 т/hectare. A chistiy profit is 1472 Uah/hectare and level of profitability 38,4%. For the study of influence of basic till of soil and efficiency of syderativ and straw in the system of fertilizer of corn it is set on grain, that the greatest productivity of 10,04 т/га is got for ploughings on 20-22 see under an intermediate culture (mustard is white) and discuvannya on 10-12 see under a corn for bringing on a background N120Р90К120 of straw with the compensative dose of nitrogen from the calculation of N10 on 1 т of straw, chistiy profit 3647 Uah/hectare. For the study of different methods of establishment of norms of fertilizer of corn the greatest harvest of grain of 11,83 т/hectare is got for bringing of mineral fertilizers in obedience to a calculation-balance method, chustuy profit 2869 Uah/hectare Product Description popup.authors Малиновська Світлана Петрівна popup.nrat_date 2020-04-02 Close
