Abstract
The experiment was conducted on Rawa area at AL-Anbar Governorate- Iraq, during the 2021 and 2022 seasons by using 72 olive trees (cultivar Ashrasi) treated with 0, 15, and 25 kg per olive tree from composted of common reed waste + cow, sheep, and poultry manure, also tree treated with 0 and 50 liters from aqueous extract of compost. The results of the statistical analysis showed that: The treatment of 25 kg.tree−1 from compost consisting of 80% common reed waste with 20% poultry manure with 50 liters of aqueous extract of the compost led to a highly significant improvement in vegetative growth traits (shoots length, number of leaves per shoots and leaf area), concentration of chlorophyll and leaf mineral content (N, P, and K) compared with control treatment during 2021 and 2022 seasons.
