| A FIELD experiment was conducted at the Experimental FarmFaculty of Agriculture, (Saba-Basha) - Alexandria University, during 2011 growing season to study the effect of four organic fertilizers (control, chicken manure, cattle manure and compost) and four rates of sulphur (0, 100, 200 and 400 kg S Fed-1) and their interactions on the yield (dry mass), quality (T.S.S, sugar and protein contents) and uptake of micronutrients (Fe, Cu, Mn, and Zn) of carrot (Daucus carota L.). After plant harvest, the soil pH, EC and availability of Fe, Cu, Zn and Mn in soil were determined. These results showed that organic fertilizers increased significantly the dry mass and T.S.S, sugar, nitrogen concentrations and protein contents of carrots than that plants not received any fertilizer. The highest response was obtained with chicken manure followed by cattle manure and then compost. The organic fertilizers increased Fe and Cu uptake and the amounts of available Fe, Cu, Zn and Mn in soil compared with the control soil.On the other hand, organic fertilizers decreased Mn and Zn of carrot plant compared with control. Also, application of cattle manure and compost decreased significantly pH andEC of soil except with chicken manure. Increasing sulphur application rates increased significantly the dry mass, T.S.S, sugar and protein content and micronutrients uptake by the carrot. Also, application of elemental sulphur increased the soil EC, available micronutrients and decreased soil pH. The highest response of carrot depends substantially on the interactions of sulphur and organic fertilizer. The highest values of dry mass, total soluble solid, sugar and protein content and Fe and Cu uptake by plant roots were observed with application of chicken manure combined with sulphur at a rate 400 kg fed-1. Also, Cu, Mn and Zn availability in soil was observed with application of chicken manure combined with sulphur at a rate 400 kg fed-1,while Fe available was observed with application of chicken manure combined with sulphur at a rate 100 kg fed-1.Correlation analyses showed the influence oforganic fertilizers and sulphur as important materials for improving the uptake of the Cu, Fe, Mn and Zn in carrot plant. | ||||
