Although the application of inorganic fertilizers to plants boosts their growth and yield, their persistent apply impacts soil heath and engenders environmental pollution. On the other side, plant organic fertilization and bio stimulants upgrade nutrients absorption, growth, yield and fruit quality as well as are environment-friendly. Thus, the current experiment was devised during 2022/2023 and 2023/2024 to explore the influence of composted filter mud (CFM), recommended fertilizer doses (RFD) and seaweed extract (SW) on the performance of the banana CV. Williams, planted in a clay loam soil at Dandara, Qena governorate, Egypt. Banana plants were planted at a distance of 3.5x3.5 m and three suckers were selected for each hole in a completely randomized block design consisting of three replicates. The quantities of RDF or half RDF were added twice monthly from April to October for both seasons. The CFM is added once around plants at a depth of 15 cm and covered with soil in mid-December for both seasons. Seaweed extract (SW) is added as soil drench three times per season from March to May. Seven treatments were applied i.e. 1) Control (RFD), 2) 10 ton/fed CFM+1/2 RFD, 3) 5 ton/fed CFM + 1/2 RFD, 4) 10 ton/fed CFM+1/2 RFD+ 0.1% SW, 5) 10 ton/fed CFM+1/2 RFD+ 0.2% SW, 6) 5 ton/fed CFM+1/2 RFD+ 0.1% SW and 7) 5 ton/fed CFM+1/2 RFD+ 0.2% SW. Results elucidated that applying 10 ton/fed CFM+1/2 RFD+0.2% SW, followed by 10 ton/fed CFM+1/2 RFD+0.1% SW positively improved the growth parameters, fruit yield and fruit quality.
