Energy and Economic Efficiency of Muscle Growth Growing in the Southern Steppe of Ukraine Under Drop Irrigation

Abstract

In the article technological methods energy and economic evaluation of growing sage in southern steppe of Ukraine conditions have been analysed. The economists’ views on the raw medicinal herbs under drip irrigation formation of efficient production have been considered. The analysis of previous agronomic studies on the cultivation of crops under drip irrigation has allowed us to conclude that there are no such results on the plantations of Salvia sclarea. The yield level of Salvia sclarea inflorescences was stable during the first three years of using, on the average in the first year it was 9.51 t/ha, in the second year it was 9.38 t/ha, in the third year it was 9.69 t/ha. Only in the fourth year of crops using (the fifth year of life) the yield was decreasing sharply. On the basis of yield data, the calculation and analysis of such indicators as energy efficiency, energy intensity of growing 1 kg of inflorescences and the conditional net profit when growing sage in drip irrigation in southern Ukraine. The maximum values of energy efficiency ratio were obtained in the first year of using and sowing in the first decade of December against the background of N60P90 - 3,25 application. When the crops sowing was postponed to the first decade of April, this indicator decreased twice to 1.59. In our experiment the minimum values of energy ratio of Salvia sclarea growing technology were obtained in the fourth year of plantation using. The classical indicators which reflect the economic and energy efficiency level of inflorescences of nutmeg production at long-term use of a culture plantation culture have been analysed. The analysis of the factors which influence for efficiency change of cultivation of culture was carried out. The mechanism of efficiency increase of cultivation of sage nutmeg in the conditions of the southern Steppe of Ukraine has been offered.

Agroecological Transformation in the Salt Composition of Soil under the Phosphogypsum Influence on Irrigated Lands in Ukraine

“…For this purpose, calculations were carried out based on the results of experimental studies, including mean values; variances; mean square deviations; absolute errors; relative errors; coefficients of variation; correlation coefficients; regression coefficients; confidence intervals for the mean value; and least significant difference (LSD). To perform these calculations, the software-information complex "Agrostat (v01)" [47] was used as an add-on to the Microsoft Office Excel 2003 program.…”

Останні мають ряд методичних розрахунків: дози розраховані на приріст врожаю або на заплановану врожайність з урахуванням вмісту поживних речовин у ґрунті.…”
