Economic efficiency of applying mineral fertilizers on crops of white burkun (Mellilotus albus)

Abstract

Goal. To determine the indicators of economic efficiency of cultivation of white annual burkun (Mellilotus albus) depending on the variety composition, the width of the rows, and the doses of nitrogen fertilizer in the conditions of the South of Ukraine. Methods. Field — to study the interaction of the research object with the biotic and abiotic factors of the Steppe; mathematical and statistical — for conducting dispersion analysis and statistical processing of data to assess the reliability of research results; comparative calculation — for the economic assessment of crop cultivation. Results. To objectively justify the most rational combination of agricultural measures, calculations of the economic efficiency of growing white annual burkun were carried out. It was established that non-observance of the optimal width of rows and the dose of nitrogen fertilizer significantly affected the economic indicators of crop cultivation and led to losses of gross production and its value. The difference in the cost of the gross production of Pivdennyi and Donetskyi annual varieties was 3.8 thousand hrn/ha. The analysis of economic indicators of cultivation of different crop varieties showed that the highest cost of gross production — UAH 55,600/ha — was typical for sowing of Pivdennyi variety of burkun with the use of a row width of 45 cm and the application of nitrogen fertilizer in a dose of N60. The combination of the above factors contributed to obtaining the lowest cost per ton of seed material, namely UAH 21,174. The final indicator of economic efficiency — the level of profitability — at the same time was the maximum and amounted to 372.0%. Conclusions. Optimizing the elements of agrotechniques for the cultivation of white burkun contributes to ensuring the highest value of gross products, the lowest cost, and the maximum level of profitability of growing seeds of the crop.
