Abstract
A Field experiment was conducted to compare the effect of urea as a fertilizer on growth, yield and post harvest life of cauliflower ( Brassica oleracea L). Four levels of urea were compared with the recommendation of the Department of Agriculture (DOA), using a Randomized Complete Block Design. Other cultural practices and crop protection were done according to the recommendations of the DOA. The plant height at one week after transplanting and 50% flowering, number of leaves at 50% flowering, total leaf area at time of flowering, total number of days to flowering, and time period for curd maturity were recorded in each treatment. The average cauliflower curd yield in the field varied between 90 - 125 g/plant (3.6 – 5.0 t/ha). The results revealed the possibility of increasing N dosage up to 125% of the DOA recommendation for obtaining larger curds and a higher curd yield. Significant difference was not observed (p>0.05) among the treatments in any of the curd quality parameters measured. Even though no significant difference was observed among the post harvest quality, curds of the 50% nitrogen fertilizer treatment stored at room condition and in polythene bags could be kept 6 days & 9 days longer than other treatments, without decay.
