Abstract

Response of cabbage plantsto different rates of chicken manure (00, 10 and 20 m³/fed.), levels of mineral N (00, 60 and 120 kg N/fed. as ammonium nitrate) and humic acid foliar treatments (0, 1 and 2 g/l) as well as their interactions was studied at the Experimental Station Farm, Faculty of Agriculture, Alexandria University during two growing seasons of 2007/2008 and 2008/2009. The obtained results indicated that application of 20 m3/fed. of chicken manure showed more superior effect on vegetative growth characters (plant weight, non wrapper leaves weight and number, as well as total head yield and its component (net head weight, head length and diameter), and N content of inner edible leaves. Addition of 120 kg N/fed. mineral N fertilizer increased plant weight, head weight, head diameter and total head yield; increased N content and decreased total sugar content of inner leaves. Foliar application of humic acid improved plant weight, stem diameter, total head yield and its component (head- weight, length and diameter). Nitrogen content of inner edible leaves was also increased while total sugar content was decreased. Application of the highest rate of chicken manure (20 m3/fed.) combined with the highest level of mineral N (120 kg N/fed.) or humic acid (2 g/l) was found to be favorable for the cabbage to express their best performance on plant weight, net head weight and total head yield. In general, the obtained results reflected high response of cabbage plants cv. "Brunswick" for fertilization with organic and mineral N fertilizers with humic acid, reflected as promoted plant growth and increased head yield and quality under the conditions of the present study.
