Was designed using a completely randomized block design (CRBD) 4*4 with three replications. The arrangement of treatment is as follows, the first treatment was chemical fertilizer (NPK) consisting of four levels (0, 50, 75and 100) % of recommended application dose. The second treatment of two types of poultry manure (0, 4ton ha−1 domestic, 4ton ha−1 imported, and 2ton ha−1 from domestic and imported), results obtained from this study can conclude as follows. All parameters (Plant height, Number of leaves, Leaf area, Stem diameter, Biomass, and Chlorophyll content in heaves) significantly differ is by levels of chemical and organic fertilizers compared with control, the combination between 50% of recommended chemical fertilizer and 2 ton ha−1 of both organic fertilizer gave the highest value for all parameters.
