Abstract : Experiments were conducted to study the effect of fertilizer levels on vegetative growth, flowering and corm production characteristics of gladiolus cv. White Friendship under mango orchard conditions in Raipur, Chhattisgarh, India, during 2004/05 and 2005/06. The maximum number of leaves per plant and number of florets per spike remaining open at a time, were recorded with N50P25K25 g/m2, whereas significantly maximum plant height was obtained by application of N40P20K20 g/m2. N10P5K5 g/m2 advanced the time for showing colour in the first floret. Application of N40P20K20 g/m2 significantly increased spike length, number of florets per spike, diameter of first floret, life of spike including durability of the whole spike under field conditions. A gradual, steady and significant increase in corms produced per plant, corm size and weight including the number of cormels per plant was observed with increasing fertilizer levels recording highest values at N50P25K25 g/m2.
