Two experiments were carried out on garlic clone Sids 40, in the vegetable private farm at Tawila village Dakahila Governorate during two successive seasons 2003/2004 and 2004/2005 to study the effect of chicken manure (10 and 20 m³/fed), three phosphorus levels (25, 50 and 75 kg P₂O₅/fed), phosphorien (with 3 kg/fed and without) and potassium fertilization (soil fertilization 72 kg K₂O/fed and 60 kg K₂O/fed + 1% K₂O/fed as foliar fertilization) on growth, yield and its components, chemical composition and storability of garlic. The results indicated that treatment of 20 m³ chicken manure/fed + 50 kg P₂O₅/fed + with phosphorien (3 kg/fed) + 60 kg K₂O/fed + 1% K₂O/fed foliar fertilization gave the best results for (fresh weight/plant, dry weight /plant, leaf area/plant, bulb diameter at 160 days after planting, weight of bulb/plant, bulb yield/fed, N, P and K percentage and total chlorophyll content) during the two seasons. But, it had the lowest values of bulbing ratio at 120 and 160 days after planting at the two seasons, the same treatment had the lowest value of total weight of loss percentage of bulbs in the second season. While the treatment of 20 m³ chicken manure/fed + 75 kg P₂O₅/fed + without phosphorien + 60 kg K₂O/fed + 1% K₂O/fed foliar fertilization gave lowest value of total weight of loss percentage of bulbs in the first season. Therefore, the treatment of 20 m³ chicken manure/ fed + 50 kg P₂O₅/fed + with phosphorien ( 3 kg/fed) + 60 kg K₂O/fed + 1% K₂O/fed foliar fertilization could be recommended for raising garlic yield with good quality bulbs.
