GROWTH, FLOWERING, CORM YIELD AND CORM-ROT INCIDENCE AS AFFECTED BY LEVEL AND FREQUENCY OF POTASSIUM APPLICATION IN GLADIOLUS (GLADIOLUS-GRANDIFLORUS)

Significantly higher corm weight and less incidence of corm rot were n oticed when potassium was applied @ 100 kg/ha to 'Pink Friendship' gla diolus (Gladiolus grandiflorus L.). But significantly higher number an d weight of cornels/plant were obtained when K was applied @ 200 kg/ha . Other parameters like vegetative growth and floral characters were n ot significantly influenced by graded levels and their methods of pota ssium application. The interactions between graded levels and methods of potassium application were non-significant for all the parameters s tudied.
