Effect Of Some Treatments On Growth, Flowering, And Bulb Yield In Hyacinth Plant.

Abstract

The experiment was carried out inside the wooden canopy of the Department of Horticulture and Landscape Design, College of Agriculture and Forestry, University of Mosul, during the period from 1/11/2023 to 1/6/2024, the aim is to study the effect of the best types of natural waste (yeast powder, orange peel powder, potato peel powder, eggshell powder) at two concentrations (5 and 10 g per pot) on the growth and flowering of Hyacinthus orientalis L bulbs, variety (Carnegie)white flower Natural waste was added in powdered form in three batches: the first at planting, the second after bulb emergence, and the third one month after bulb emergence. The experiment was carried out in a completely randomized block design (RCBD) with three replicates, the results showed that yeast powder at a concentration of 5 gm was superior in the characteristics of plant height cm, number of leaves, length of leaves cm, weight of bulb g, and reached 30.133, 6.1000, 23.507, 49.4667 respectively, while yeast powder at a concentration of 10 gm was superior in the characteristics of number of days to flowering, number of bulbs, and reached 77.900, 1.2767, respectively, while eggshell powder at a concentration of 5 gm was superior in the characteristics of flower stalk weight 39.600 gm and orange peel powder at a concentration of 5 gm was superior in the characteristics of bulb volume 58.4667 cm³.
