Irrigation equal to replenishing 120% of panevaporation (Epan) showed the maximum average growth and flower yield (7240.8 kg/ha) and actual evapo-transpiration (527.5 mm). However, the average water use efficiency was the highest (15.59 kg/ha-mm) with the irrigation replenishment of 40% Epan. Nitrogen levels had significant influence on the growth, dry matter production, flower yield and floral parameters. Nitrogen at higher level had marginal effect on the water use efficiency.
