Effect of Nitrogen, Phosphorus and Zinc Nutrition on Spike and Floret Development in Gladiolus

Gladiolus (Gladiolus grandiflorus L.) cv. Eurovision was studied in respect of N, P, Zn nutrition for spike growth and development and florets number at K.A.D. College, Allahabad, C.S.J.M. University during 2006-07 and 2007-08. Single application of N, P, Zn, N2, P2, Zn2 produced 36.85, 32.86, 32.17 cm and 35.73, 32.84, 32.36 cm spike length during 2006-07 and 2007-08, respectively. Combined treatments of N2xP2, N2xZn2 revealed considerable effects for spike length. Application of N2xP2xZn2 treatment showed best effect with maximum spike length 47.16 and 48.26 cm in 2006-07 and 2007-08, respectively. Application of N, P, Zn treatments were found to have favorable response to number of florets/spike in gladiolus.
