Effect of NPK, Humic Acid, Biofertilizer and Light Intensity on Vegetative Growth and Bulb Production of Narcissus trilandrus L. and Hyacinthus orientalis L.

This research was carried out in order to compare among three different fertilizers: bio, chemical, and organic. on two plants selected conduct this were (Narcissus Hyacinths), which cultivated shaded non-shaded locations from Autumn 2020 Spring 2021 Gerdarash field at the college campus. The vegetative traits of plants, as well production bulblets, measured properly. Regarding Narcissus, bio-fertilizer showed most promising result when it came number leaves bulblets (3.67, 1.67 per plant respectively). chemical fertilizer better results height (32.67 cm) diameter flowers (11 cm). organic compared control. For Hyacinth proved its superiority (27 cm), flower petiole length (12.33 (32.33), (6.33cm), new with ones another treatment Whereas for lighting, we recommend planting ornamental bulbs open places obtained best floral both plants.
