Abstract
Amaranthus sp. is an important African indigenous vegetable that contributes to food security and income generation for small-scale farmers. However, its growth is often limited by soil fertility and water availability. This study investigated the effects of sawdust biochar and watering regimes on the growth and yield of Amaranthus. A 5 x 3 factorial experiment was conducted in a screenhouse, with five levels of sawdust biochar (0, 1, 2, 3, and 4 t/ha) and three watering regimes (200 ml of fresh water added once, twice, and thrice a week). The results showed that biochar application significantly increased plant height, stem diameter, number of leaves, and dry matter yield. The optimal watering regime also increased plant growth and yield parameters. The interaction between biochar and watering regimes was significant for some plant growth measurements. The study demonstrated that sawdust biochar can improve soil fertility and structure, and its application can be used to promote plant growth and yield in tropical regions. The findings of this study provide valuable insights into the potential of biochar as a soil amendment for improving soil fertility and promoting plant growth.
