Effect of spacing and nitrogen on flowering and vase life of Asiatic lily cv. Tressor under shade net condition

Abstract

The present investigation was carried out at College of Horticulture, Dr. Y.S.R. Horticultural University, Venkataramannagudem, West Godavari district, Andhra Pradesh during the crop season of 2016-17. Three levels of spacing (15 cm x 15 cm, 25 cm x 15 cm and 30 cm x 15 cm) with three nitrogen levels (100, 150 and 200 kg ha-1) were used in present study. The experiment compromising of 9 treatment combinations was laid out as factorial randomized block design with three replications. Results showed that the 30 cm x 15 cm and 200 kg N ha-1 had a significant effect on days to flower bud emergence, days to colour visibility in bud, days to 50 % flowering, days taken for harvesting of flowers, number of flowering shoots per umbel, flower diameter, flower weight, field vase life and postharvest vase life. Among interaction effects, treatment combination of 30 cm x 15 cm with application of 200 kg N ha-1 was found more effective in enhancement of floral attributes.
