Observations Concerning the Effect of Agryl on Environmental Factors of Cabbage Cultivated in Plastic Tunnel and Field

Abstract. The white head cabbage (Brassica oleracea L.), was cultivated including the Stone Age and gained a spread in almost all of the region of temperate climate on Earth, even the warm climate areas, having a large ecological plasticity (Apahidean, 2007). It is cultivated for a large spectrum of use, mostly in culinary art, it is eaten uncooked, preserved in salt, with or without meat, refrigerated or dehydrated (Chilom, 1991), but is also a basic material for canned use, especially for vitamin juice, usually mixed with carrot juice. This vegetable is used not only for human alimentation, but for natural medicine, too. To obtain extra early cabbage productions in our country represents a large interest, mostly concerning the regions of the Transylvanian Plateau, because of the cool climate, the crops are gathered later, also in the Danube’s Plane, or the country’s western Planes. The research objective was to study of the effect of Agryl P-19 on the environmental factors on early cabbage cultivated in plastic tunnel and field. The main line was, to obtain an early, but quality production. In the experiment it was used six hybrids and one early cabbage cultivar, the non-woven agrotextile Agryl P-19, to cover directly of cultures in plastic tunnel and field as well
