Juniper Publishers-Open Access Journal of Environmental Sciences & Natural Resources Influence of Spike Removal and NPK Levels on Corm Growth and Development of Gladiolus Authored by Shafiullah Abstract An experiment to evaluate the influence of spike removal and NPK (mix fertilizer) levels on corm growth and development of gladiolus were conducted at Horticultural Research Farms, Department of Horticulture, The University of Agriculture Peshawar, Pakistan. The experiment was laid-out in Randomized complete block Design in split plot arrangement with two factors i.e. NPK (mix fertilizer) levels at the rate of 0, 50, 100 and 150 kg ha -1 and spike removal that is control (no removal), spike removal at spike emergence stages and spike removal at flower opening stages. Different growth and yield parameters were observed. Data analysis showed that NPK (mix fertilizer) levels, spike removal stages and their interaction had a significant influence on almost all the studied parameters
