Growth and physiological characteristics of Narcissus pseudonarcissus at different nitrogen levels
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 2
Abstract
In this study, effects of various nitrogen treatments on growth and physiological characteristics of Narcissus pseudonarcissus were evaluated. The present study was carried out in Department of Horticulture, Faculty of Agriculture, Islamic Azad University of Isfahan (Khorasgan) branch. Flowers were grown in sandy soil containing with different levels of preservatives, including, ammonium nitrate (0, 100, 200 kg.ha-1). Completely Randomized Factorial Designs was applied to test the significance of treatments and means were compared using Duncan's multiple range test at P = 0.01. Results showed that using ammonium nitrate treatments significantly affected leaf longevity, bulb and bulblet diameter, concentration of carbohydrates and chlorophyll a, b and total chlorophyll contents. About of using ammonium nitratethe best dosage was 200 kg.ha-1. In conclusion, the best treatment to enhance growth and physiological characteristics of Narcissus pseudonarcissus, was the exact 200 kg.ha-1 ammonium nitrate. This treatment can be proposed as additional substance for Narcissus pseudonarcissus growth increasment.
