| Abstract | The article gives the results of investigation of the influence of azote, phosphorus and potassium mineral fertilizers in different doses on the hump humus of the Right-Bank Forest-Steppe of Ukraine with the holding of before-sowing campaign inoculation as well as without it, on the carrying out of the main elements of nutrition and the harvest of chick-pea grain. Besides, scientists grounded the amount of carrying out the main elements of nutrition by grain and straw harvest under the influence of the system of fertilization of mineral fertilizers together with inoculation of chick-pea seeds. The investigation of studying the following thematic was held under the terms of temporary experiment on the experimental field of Uman National University of Horticulture on the hump humus heavily loamy on loess. The soil of investigated areas was characterized by the content of humus – increased (3,5 %), the content of azote of alkaline hydrolytic combinations – low, movable combinations of phosphorus and potassium – medium, the reaction of soil solution – low acid. They studied the action and interaction: fertilization and inoculation. Fertilizers were used in such forms as: ammonia saltpeter, carbamide, sulphate ammonium, double superphosphate, potassium chlorus, molybdate ammonium. They used a two-year defecate with the content of CaCO3 70 % as a chalking material, the norm of insertion of which was calculated according to the hydrolytic acidity. They sowed the sort of chick-pea Rozanna after winter wheat. Two hours before sowing chick-pea seeds were treated by the substance of rhysobophyt. They defined that carrying out elements of nutrition of overground mass of chick-pea was higher in case of higher dose of mineral fertilizers. On the basis of use of N30P60K60, comparing with non-fertilized areas, carrying out the azote increased to 15,6 kg/hectare, P2O5 – to 4,9, K2O – to 14,5 kg/hectare, under the terms of insertion of N90P60K60 – according to 24; 7 and 20 kg/hectare more for control. Maximal carrying out of the main elements of nutrition by the overground mass was in case of investigation CaCO3 + basis + Mo + N30 + N30 and the use of inoculation of chick-pea seeds. By the way, comparing with non-fertilized control, carrying out of the azote by grain increased to 82 kg/hectare, P2O5 – to 31, and K2O – to 37 kg/hectare. Carrying out the elements of nutrition by chick-pea plants increased together with the increase of dose of azote fertilizers. The highest indexes of carrying out were at the insertion of phosphorus and potassium fertilizers, 60 kg/hectare, azote – 30 kg/hectare in early spring and molybdate ammonium on the basis of chaking the soil and inoculation of seeds: azote – 232 kg/hectare, P2O5 – 79, K2O – 130 kg/hectare. Weather conditions during the vegetation period and agro technological means, which were studied in the investigation, also influenced the harvest of chick-pea. | ||
