Abstract. The study refers to the production results and the volatile oil content obtained in the majoram and thyme culture under the climatic conditions of 2016-2017. Research has been conducted in the experimental field in southern Madrid. Dry herb (Herba Mojoranae) contains 0.8-1.1% volatile oil with a production of 2260-2360 kg/ha. Dry herb (Herba Thymi) contains 0.78-0.80% volatile oil with a yield of 1228-1440 kg/ha. In the experimental field to ensure the water need of aromatic plants, four irrigation norms were applied, including the first flood with a norm of 120l/m2, followed by 3 drip irrigation with a norm of 30l/m2 per irrigation. The precipitation recorded in the year 2017 were close to the needs of aromatic crops. Regarding the temperature regime no difference is observed compared to 2016. With 0.23 ml of oil obtained from 100g of dried herb, Origanum majorana L with 0.13 of oil obtained from 100g of dried herb and Origanum vulgare L., with 0.14 ml of oil obtained from 100g of dried herb.( C.
