Economic and energy efficiency of growing pea seeds depending on varietal composition, inoculants and plant protection

Abstract

Goal. The aim is to determine the economic and energyefficiency of growing pea seeds depending on the varietalcomposition, inoculants and plant protection in non-irrigatedconditions of the Southern Steppe of Ukraine. Methods.Field, economic, energy. Results. It was establishedthat the value of gross output when growing pea seedsincreased to 33.3 thousand UAH/ha in the variety DarunokStepu, and in other varieties its decrease was recorded,on average, by 5.1-24.6%. The cost of productionof seeds of the studied crop reached the maximum levelin the variety Svit - 7.5 thousand UAH/t. In the variantwithout plant protection, an increase in this indicatorwas recorded, and in the case of chemical protection itincreased by 23.4%, and in the case of biological protection- by 19.7%. The conditional net profit of the highest levelreached in the variant with the variety Tsarevich, whereit amounted to an average of 21.8 thousand UAH/ha.and in the varieties Oplot and Svit it significantly decreasedby 44.3-52.4%. Biological protection of plants led toan increase in profitability to 147.2%, and chemical - to153.8%. The minimum energy yield with pea seed yieldwas in the varieties Oplot (35.6 GJ/ha) and Svit (36.7 GJ/ha). The use of biological protection system contributed toa significant increase in this indicator, on average, by 61.5%,and chemical - by 82.7%. Conclusions. Production coststended to increase in the varieties Otaman, Darunok Stepuand Tsarevich, and the minimum rate - 12.8 thousand UAH/ha, obtained in the version with the variety Oplot. The useof inoculants had no effect on this indicator. For chemicalprotection received the maximum level of productioncosts - 13.7 thousand UAH/ha. Chemical plant protection contributed to the highest profit (21.1 thousand UAH/ha),which is 64.8% more than the control. Biological protectionwas also highly effective and exceeded control by 50.8%.The maximum level of profitability of pea seed cultivation, onaverage, 163.9 and 153.4% was provided by the varietiesTsarevich and Darunok Stepu. The use of inoculants AKMand Biogel contributed to the growth of this indicator by18.6-33.3%. The increase reached the maximum values,on average, 23.8 and 25.8 GJ/ha for the cultivationof Darunok Stepu and Tsarevich varieties. The coefficientof energy efficiency had maximum values of 2.18-2.28 forthe cultivation of varieties Darunok Stepu and Tsarevich.
