Fruit production under arid conditions without irrigation implies the need to employ soil cultivation in the entire orchard with the aim of regulating the water-air regime of the soil, contributing to a favorable soil structure, breaking down the soil crust and successful weeds destruction. Contemporary fruit cultivation practices are compulsory in order to achieve high yields and profitability. Additional soil tillage in orchards has a major impact on the growth and development of plants, yield and fruit quality. Optimal parameters need to be determined when employing mechanization equipment in orchard cultivation in order to make the right choice. The objective of the study was to determine energetic and exploitation parameters of different tractor/machinery tools used in additional soil cultivation. Based on the analysis of the data obtained showing both advantages and disadvantages of some soil cultivation types, it was possible the choose the optimal tool for additional soil tillage. Field trials were carried out in apple (cv. Jonagold, Idared and Melrose) orchards using the two-row Pilar cultural practice at a planting distance 3.80-1.25 x 140–1.80 m. The following tools for additional soil cultivation were used: pseudo plow PP-220, plate cultivator VVT – 223, cultivator IMT-642 and vineyard plow VP-189. The following exploitation indices were monitored: traction force, labor speed, fuel consumption and traction resistance. Based on the results obtained the smallest fuel consumption was registered using pseudo plow (3.78 l/ha) whereby cultivation depth, speed and output registered were 6.31 cm, 7.29 km/ha and 9.07 ha/day respectively.
