Effect of spraying yeast and Urea fertilizer on some vegetative properties of rose plant

Abstract

This experiment conducted in Location of Horticulture department / Raparin university during 15 March to 5 May 2019, to study the effect of different level of Yeast and Urea some vegetative propertieson growth of Rose plant.This experiment included the study of four levels of dry yeast extraction (0, 2.5, 5 and 7.5 g/L), and four levels of Urea extraction (0, 2.5, 5 and 7.5 g/L) and their interaction, The plants were sprayed with dry yeast and Urea extractions just after the emergence of the second true leaf until beginning of flowering and every 10 days.Results showed that increasing of foliar application of active dry yeast concentration up to 5 g/l increased the vegetative growth characters of Rose plants in terms of plant length, leaf area and number of brunch of whole plant. Moreover, increasing of Urea concentration up to 5gmdecreased the vegetative growth characters as mentioned above. Addition of foliar spray of yeast at 7.5 g/l. along with foliar spray of Urea at 2.5gm resulted in the highest values of the above mentioned plant growth. The experiment was laid out in pots in a factorial completely randomized design (CRD) with three replications, means were compared using Duncan’s Multiple Range Test (P≤0.05).
