Abstract:The main aim of this work is to compare organically and conventionally grown cabbage plants with regard to plant growth, nitrate and vitamin C concentrations during two successive seasons (spring and autumn). Farmyard manure (FM), chicken manure (CM) and blood meal (BM) and its mixtures (organic applications), one chemical fertilizer (conventional application) and one control, collectively 19 applications were investigated. At first glance, organic application responded well in the autumn season than that of the spring season. Plant growth, higher vitamin C and lower nitrate concentrations were obtained from 3.5 CM, 15.0 FM and 5.0 FM+1.2CM+0.4 BM applications in the spring season; and 10.0 FM+1.2 CM, 3.5 CM and 2.5 CM+0.3 BM applications in the autumn season, respectively. It is tempting to assume that the applications containing CM were superior to the others; therefore; having integrated the results in term of plant growth, yield, vitamin C and nitrate concentrations; 3.5 CM in the spring and 10.0 FM+1.2 CM in the autumn season could be recommended and be used successfully in growing organic cabbage, and also be substituted by chemical fertilizer.
