Abstract
Cauliflower cv. Snowball Y Improved plants were treated with seven treatments (80 kg N fed", 60 kg N fed-' + 2 kg Nitrobin fed", 60 kg N fed-' + 10 m3 chicken manure fed-', 60 kg N fed" + 2 kg Nitrobin fed-' + 10m3 chicken manure fed-', 40 k~ N fed" + 2 kg Nitrobin fed", 40 kg N fed" + 20 m3 chicken manure fed", 40 kg N fed- + 2 kg Nitrobin fed-' + 20 m3 chicken manure fed-') in two field experiment conducted at Baramoon Experimental Farm, Oakahlia Governorate during 2002/2003 and 2003/2004 seasons. These treatments had significant effects on all traits under study. Using 60 kg N fed" + 2 kg Nitrobin fed" + 10 m3 chicken manure fed-" and 40 kg N fed" + 2 kg Nitrobin fed-' + 20 m3 chicken manure fed" gave the highest values for leaves weight I plant, curd weight and diameter, protein (%) and curd yield per feddan as well as N, P and K accumulation in leaves and curd. The same treatments reduced vitamin C (VC) content, protein (%), dry matter (OM) (%) and mean time from transplanting to maturity. Treatment with 40 kg N fed" + 2 kg Nitrobin fed" recorded the highest values for VC content and OM%. Treatment with 80. kg N fed" recorded the highest values for N03 accumulation in curd and mean time from transplanting to maturity. So, application of 60 kg N fed-' + 2 kg Nitrobin fed" + 10m3 chicken manure fed" or 40 kg N fed-' + 2 kg Nitrobin fed" + 20 m3 chicken manure fed-' was sufficient and could be recommended for good yield and quality of cauliflower under similar conditions of this work.
