Економічна та біоенергетична ефективність вирощування ріпаку ярого гібриду Юра

Abstract

The highest profit was obtained by applying fertilizer (N90P75K120) - 4828 UAH / ha for a profitability of 102%, the lowest - at the lowest dose of fertilizers N45P30K45 - 2008 UAH / ha, while the profitability was 63%. In terms of fertilizer N60P45K60 profit was 3616 UAH / ha with a profitability of 97%, and the value of gross output amounted to 7336 UAH. The use of fertilizer borers N120P75K120 slightly increased the cost compared to the option with the highest profit - from 4720 to 4947 UAH / ha, but the profitability dropped to 71%. Thus, according to economic indicators of profit per hectare and profitability, the best result was the fertilizer variant N90P75K120, where the value of gross output was UAH 9548. A further increase in fertilizer rates led to a decrease in these indicators and in this case it was not economically feasible. The lowest energy consumption was in the experiment without fertilizer application (28952 MJ), while the energy efficiency ratio was 4.99. At the same time, the highest energy consumption was characterized by the use of mineral fertilizers in the amount of N90P75K120 and nitrogen feed (30 kg / ha) - 56095 MJ, with an energy efficiency ratio of 2.96. With further increase in fertilizer rates, the energy output with the harvest decreased. Hybrid Yura is recommended to grow according to the technology, which provides for the introduction of mineral fertilizers at the rate of N90P75K120 kg / ha d. P. For the seed rate of 1.0 million similar seeds. It is proved that such a fertilizer rate is economically advantageous and expedient from the standpoint of economic and energy efficiency under the given growing conditions.
