n order to increase the production of the mangel-wurzel-beet, the improvement of the quality of the crops is expected, which will be achieved using genetic engineering techniques and modern technologies, such as the usage of vegetal bio-stimulators with the purpose of influencing the growth and the development of the plants. Nowadays the bio-stimulators are very often used in biological agriculture not only for lawns, but also for fodder cultivation, successfully replacing some polluting products. The agro fond and the crop-rotation have had a direct influence on the level of production of the studied mangel-wurzel genotypes in Timisoara (2007-2008). To the two factors mentioned above, the positive influence of the products with a bio-stimulating role was added. The beet capitalizes on manure. At all doses of manure applied, increases of production are obtained in comparison with the untreated sample. The greatest increases of production are obtained at the mangel-wurzel breed Kyros, at a dose of 80 t manure/ha. (132,9 kg/ha). Analyzing these measurements from the point of view of the increase in production for 1 kg of used manure, one can notice that at the doses of 40 and 60 t/ha, the increases in production are higher than at the maximum dose for the mangel-wurzel.
