During October 2003 to August 2004 has been study with winter common vetch Vicia sativa L. cv. NS Sirmium. Early spring plowing of plots and green manure practicing enabled soil organic fertilization. On the same plots were set up carrot cv. Nantes compared with control. Soil samples were taken before common vetch sowing, after its decomposition and the first carrot gathering. Carrot quality is evaluated through chemical analyzing of carbohydrates, protein and vitamin C content. Resulted of green manuring soil humus, nitrogen, light available phosphorus and potassium were larger. Number of carrot plants (39.27), dimensions (20.75 cm x 2.07 cm), weight (59.88 g) and extracted sap (22.18 ml per plant) after the 1st gathering are an average increased and yield per plant as well yield in total. Except extracted sap all investigated mentioned parameters were continue gained after the 2nd gathering (23.22 cm x 2.69 - dimensions, 62.44 g - weight, 18.45 - extracted sap). Carbohydrate content is higher at organic produced carrot (20.15% /100 g d.m. - total; 7.48%/100 g d.m.), protein either less as well (10.56%/100 g d.m.) and vitamin C significantly 3.41%/100 g f.m. then control 2.47%/100 g f.m.
