| Abstract | ||
| This investigation was undertaken for two seasons 2005/2006 and 2006/2007 on Williams cultivar grown in loamy soil in a private orchard at Badaway, near Mansoura, Dakahlia governorate. Treatments included in the experiment were : the recommended nitrogen rate in the mineral form (ammonium nitrate 33 % N) as the control, 50 % mineral N + 50 % town refuse, 25 % mineral N + 75 % town refuse, 50 % mineral N + 50 % cattle manure and 25 % mineral N + 75 % cattle manure. Pseudostem length, circumference, suckers length, circumference, number of green leaves/ plant, finger length, diameter, size, weight, percentage of pulp, weight of bunch and hand, chlorophylls A and B in the finger peel, total carbohydrates, nitrate and nitrite in finger pulp and leaf mineral content (NPK) were monitored each season (2005/06 and 2006/07). The application of nitrogen requirements in the form of organic manure (cattle manure followed by town refuse at 75 % + 25 % mineral N) gave a good results in respect to the most of studied characters in comparison with the treatments which received the amount of nitrogen from mineral source only. Generally, increasing the rates of organic manure up to 75 % + 25 % mineral N, the obtained results were improved particularly the yield, fruit quality and vegetative properties. The highest nitrate and nitrite residues in the finger pulp were observed in mineral N fertilization alone, whereas the lowest values were gained from compost treatments (organic manure). | ||
