Abstract

Plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. In this study, field experiment carried out as factorial Randomized Completely Block Design (RCBD) in 3 replications. Different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. Second factor was different plant spaces (10, 15, 20 and 25 cm). Results showed that the 25 cm plant space had a significant effect on flower stalk height, stem diameter, spike length, floret diameter, floret weight, vase life and nutrient uptake. Nitrogen levels affected on stem diameter, spike length and nitrogen uptake. The results show that using 200 kg/ha N can improves growth and yield of tuberose as flower stalk height, stem diameter and bulb weight. Data showed that the maximum quality and quantity of flower obtained in 25 cm plant spacing plus 200 kg/ha N.
