This paper presents the results of the influence of applied agro-technical measures on yield and content of essential oil in basil (Ocimum basilicum) and reduce energy consumption during plowing, using a combination plow and subsoiler. Of technological operations, in addition to core processing, we applied the inter row cultivation of land to destroy weeds and maintain land in a loose condition which prevents drying and provides moisture retention. To the introduction of nutrients into the soil, which are needed for plant growth, feeding was carried out basil fertilizers. Applied two depth-plowing: 20 to 40 cm. Realized yields and essential oil contents were in the function of the depth of plowing. The results achieved show the highest yield of basil on the depth of plowing 40 cm (from 2900 kg/ha to 3200 kg/ha), while the actual return on the depth of plowing for 750 kg/ha greater than the highest yield of the plowing depth of 20 cm. Realized yields of basil is a measure of deep plowing effects on the development of plants and realized yield and increased economic efficiency of application of deep tillage in the production of basil. Essential oil content expressed as a percentage of the depth of plowing 20 cm ranged from 0.40% to 0.60%, and the plowing depth of 40 cm varied in the range of 0.63% to 0.87%, which is 0.23% and 0.27% over the plowing depth of 40 cm. The results concluded that increasing the depth of plowing increases the yield and content essential oil in basil production.
