Description An experiment was conducted during the winter season (October to February) of 1989-90 and 1990-91 to study the effect ofdifferent irrigation frequencies and N levels on dry-matter production, curd yield and wateruse or 'Snow Ball' caulifiower(Brassica oleracea L. var botrytis L. subvar cauliflora DC. ).lrrigations of 30 mm were given at frequencies to replenish85.50, 75 and 100% of the accumulated evaporation from a USWB class A pan (Epan) in combinations with N @ 0, 60, 120 and 180kg/ha. Significant increase in plant height, number of leaves and leaf area /plant was observed upto 50% Epan replenishmentlevel, beyond which the increase was marginal. Crop receiving most frequent irrigations accumulated the highest dry matter inleaf(85.2 g/plant), stem (28.4 g/plant) and curd (31 g/plant), leading to maximum total dry-matter production (144.6g/plant). An increase in irrigation water applied from 25 to 100% of Epan linearly increased the curd yield (8.06-16.22tonnes/ha) along with increase in crop evapo-transpiration (238-541 mm). However, irrigation regimes did not affect the fieldwater-use efficiency. N @ 180 kg/ha gave maximum dry-matter production (162.4 g/plant) and curd yield (18.61 tonnes/ha) butwas at par with 120 kg N/ha. The N fertilization did not greatly affect the crop evapo-transpiration. N @ 180 kg/ha gave 4.48kg curd yield and 2.2 kg dry biomass for every mm of water consumed. Decrease in N level from 180 to 60 kg N/ha reduced thewater-use etfficiency by 33%. The differences in water-use efficiency were caused by an effect of N nutrition on the curdyield rather than on the water use by the crop.
