The effect of different sources (KNO3, K2SO4 or KCl) and rates of K (4, 8 or 12 g K/m2) on the quality and vase life of gladiolus was studied in field experiments in West Bengal in 1993 and 1994. Application of K2SO4 at 4 g/m2 produced the greatest number of flowers per spike, while flower diameter was greatest with 8 mg K/m2. After harvest the spikes were placed in 4% sucrose solution. Longevity was greatest following application of 8 mg K/m2 as K2SO4. The application of K2SO4 at low and KNO3 and K2SO4 at intermediate rates gave the greatest number of flowers opening at one time. However, field application of KNO3 at 12 g/m2 gave the longest period of prime quality.
