SCIENTIFIC BASES WAYS OF INCREASING (CICER ARIETINUM L.) PRODUCTIVITY IN UKRAINE

Based on long-term reviews of specialized sources literature concerning spreading of peculiarities of modern cultivation technology and productivity of Cicer arietinum L. in different natural and climatic conditions of Ukraine, it was found, that crop capacity varies from 1.4-2.7, but due to proper agrotechnics and weather conditions it could be 2.5-4.2 t/ha. Under extreme conditions of cultivation (drought, etc.), crops are reduced to 0.7-1.0 t/ha. There are increasing of demand for expantion of the area under Cicer arietinum L. cultivation in Ukraine: in recent years the area of crops has increased significantly and amounts for more than 100 thousand hectares. Seeds of this culture contains 28-32% protein and up to 7% oil. Cicer protein according to the amino acid composition is very close to the ideal FAO protein, with its biological value of 52-78%, and the digestibility coefficient is 80-83%. In symbiosis with nitrogen-fixing bacteria, pinholes can absorb 80-150 kg/ha of nitrogen in the active substance. Cicer arietinum L. crop capacity primary depend on terms keeping and methods of sowing, seed rates, biological characteristics of the variety, fertilization, application of biopreparations, integrated plant protection system, weather and climatic conditions, etc.
