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.
