Headed Chinese cabbage growth and yield influenced?by different manure types in organic farming system

摘要

Chinese cabbage is a less known, cultivated and consumed vegetable species in Transylvania, although previous studies have shown that it can be grown successfully in this area. The main purpose of the present research was to underline the effectiveness of various treatments on Chinese cabbage growth, yield and quality of the final product in organic farming system. The treatments included: different fertilisation types, place of the culture and several hybrids. Results showed that all the studied factors had a high influence on cabbage heads characteristics such as length, diameter, and weight, on the number of leaves and also on yield. The best yields were registered when horse manure was used (between 76.50 and 99.30 t/ha), followed by cattle manure (between 76.80 and 93.75 t/ha). A higher yield of better quality cabbage was obtained in a polyethylene tunnel (89.27 t/ha) compared to the open field culture (77.50 t/ha). Hybrid Super provided the highest yield (92.70 t/ha), followed by hybrid Vitimo (86.09 t/ha).
