Impact of Nitrogen and Phosphorus on Cormel Production in Gladiolus grandiflorus L. Cv. White Prosperity

Gladiolus occupies an important place among the most popular bulbous ornamental plants. To optimize the production technology for this important plant, a field experiment was conducted at the Horticulture Experimental Farm, School of Agricultural sciences and Rural Development, Nagaland University, Medziphema Campus to study the effect of nitrogen and phosphorus on cormel production in Gladiolus grandiflorus Cv. White Prosperity. The experiment was laid out in Randomized Block Design with two factors viz. nitrogen (0, 250, 300 and 350 kg/ha) and phosphorus (0, 150, 200 and 250 kg/ha), replicated thrice. Data was recorded for different parameters including cormel per plant and plot during the course of the study and statistically analyzed. Application of nitrogen and phosphorus @ 300 and 200 kg ha-1 respectively results in better production of cormel. For better cormel production, nitrogen and phosphorus can be applied @ 300 and 200 kg ha-1 respectively.
