Abstract

Spacing of plants and nitrogen availability are the two most important factors affecting the quality and quantity of tuberose. In this study, a field experiment was carried out as a factorial in a Randomized Complete Block Design (RCBD) format with 3 replications at MNOPRS. Different levels of nitrogen (0, 50, 100, 150, 200, 250 Kg/ha), in the form of ammonium nitrate was the first factor and the second factor was the different plant spacing of (10 x 10, 15 x 15, 20 x 20, 25 x 25 cm x cm). The spacing between plants of 25 x 25 cm had a significant effect on flower stalk height, flowering stem diameter, spike length, floret diameter, floret weight, vase life, bulb number and weight. Nitrogen levels affected stem diameter, stem and spike length. The results showed that an application of 200 Kg/ha N can improve growth and yield of tuberose in terms of flower stalk height, stem diameter and bulb weight. Data showed that the plant spacing of 25 x 25 cm with nitrogen application of 200 Kg/ha N obtained the maximum qualitative and quantitative characteristics of flowers.
