FORMATION OF THE CASTOR CROP IN THE CONDITIONS OF TRANSITION SOUTHERN PART OF THE POLTAVA REGION

Abstract

Castor-oil plant seeds value stimulates expanding this plant growing area due to significant climate warming in Ukraine. Five-year indices of climatic conditions of castor-oil plant vegetation period in the transitional south part of Poltava region are analyzed. It is established that high temperature and adequate moisturizing during castor plant vegetation under seeding rate of 40000 items per hectare facilitated forming crop productivity of nearly 31,5 centners per hectare with oil content of more than 52 %. Obtained data confirm advisability and possibility of growing castor-oil plant in Poltava region.
