According to official statistics, cabbage is annually cultivated in the area of 120-150 thousand ha in Kazakhstan, and there is still a demand for cabbage in local market. Therefore, there are high requirements to productivity and quality of cabbage. Due to a high demand for healthy food, including vegetables, the research on cultivation of cabbage by using biofertilizers and organic fertilizers promotes to increase a number of local farmers that grow ecologically safe products. The present study was conducted to investigate the effect of biofertilizers and organic fertilizers on yield, quality and ecological purity of cabbage crop. Data were collected for 3 consecutive years. Among different biofertilizer variants, variant with manure 60 t/ha + Straw 3 t/ha + N₃₀ produced the highest yield in cabbage followed by variant with manure 60 t/ha. Both of these variants produced significantly higher cabbage yield as compared to control variant. MERC 1 l/ha variant produced cabbage with maximum vitamin C while sugar content of cabbage was highest in variant with Biosok 5 l/ha. Overall, yield and quality of cabbage was higher in biofertilizers and organic fertilizers variants as compared to control. There was observed no negative effect of biofertilizers and organic fertilizers on cabbage storability.
