    An experiment was conducted beside the central research laboratory of the University of Ilorin to study the effects of water hyacinth-derived biochar (WHB) and/or cow dung (CD) on the growth, yield, and chlorophyll content of Cucumis sativus. The treatment includes: 20 g WHB; 40 g WHB; 60 g WHB; 20 g CD; 40 g CD; 60 g CD; 10 g WHB+10 g CD; 20 g WHB+20 g CD; 30 g WHB+30 g CD. The treatments were laid out as a randomized complete block design with three replicates. Parameters assessed were plant height, leaf area, number of leaves, chlorophyll content (chlorophyll A, chlorophyll B, total chlorophyll, and carotenoids), fresh leaf weight, and dry leaf weight. Application of 60 g CD gave the highest leaf number (11.0 leaves/plants) and plant height (27.00 cm), and 40 g CD gave the highest leaf area (50.75 cm2). There is no significant difference among the treatments on the effects on chlorophyll content, but the highest value was recorded in 20 g CD (CHL A-1.31 mg/g; CHL B-0.84 mg/g; total CHL21.58 mg/g; carotenoids: 4.24 mg/g). However, 60 g WHB produced the highest fresh leaf and dry weight (35.94 g and 13.47 g). It was concluded that using CD only has a promising effect on the plant growth and leaf area of Cucumis sativus. At the same time, the co-application of WHB and CD shows little or no enhancement, especially at high dosages when compared with the control and other treatment groups. 60 g WHB shows a promising effect on the fresh and dry weight of the Cucumis sativus leaf.
