Вивчався вплив мінеральних добрив та норм висіву насіння на врожайність і якість зерна пшениці твердої ярої. Зі збільшенням доз азотного добрива ( до ) збільшується склоподібність зерна, вміст білка та клейковини в ньому, максимальна врожайність зерна формувалась за норми висіву 5-6 млн схожих насінин на гектар.

Impact of mineral fertilizers and seedling rates on the crop yield and seed quality of spring durum wheat grains. With the increase of mineral fertilizers amounts ( up to ) glassiness of grains is increasing, as well as protein and cellulose content in it, maximum wheat yield was achieved at seedling rates of 5-6 mln. germinable wheat per hectare. | Изучалось влияние минеральных удобрений и норм высева семян на урожайность и качество зерна пшеницы твердой яровой. С увеличением доз азотных удобрений ( до ) увеличивается  стекловидность зерна, содержание белка и клейковины в нем, максимальная урожайность семян формировалась при норме высева 5-6 млн всхожих семян на гектар. | Вивчався вплив мінеральних добрив та норм висіву насіння на врожайність і якість зерна пшениці твердої ярої.

Created in Nikitskyi botanical garden Remote hybrids of nectarine and peach with almond ordinary can be used in Breeding of nectarine and peach fok high resistauce to fundi, as wengs for creation of varieties of nectarine with high drought resistance, sweet seed kernels, high contents of organic substance, and other important Breeding characteristics. Late blossoming hybrid forms can be used in Breeding of almond fok late time of flowering and selfcompatibility.

Analysis of the existing methods for earliness group determination of maize varieties and hybrids according to the FAO indices was conducted. Influence of the abiotic factors on earliness of 16 standard maize hybrids in all agroclimatic zones of Ukraine at nine State Canters for Plant Variety Examination and State Variety Testing Stations during 1999-2006 was analyzed. On the base of the research results, a new method of earliness group determination for varieties (hybrids) of maize without comparison with the standard hybrids has been developed.
