The experiment’s goal was to ascertain how mulching materials affected soil temperature and moisture levels, which in turn affected the growth and yield of amaranthus (Amaranths cruentus). The Agronomy Research Farm at Delta State University’s Asaba campus conducted this study. There are various ways to mulch amaranth plants. The five mulching materials (grass, control, white poly bag, black poly bag, and almond leaves) as treatments were utilized in an RCBD (randomize full block design).For every treatment, the following parameters were measured: plant height, leaf count, soil temperature, soil moisture content, and plant yield. Every treatment was carried out in three replications. Plant height optimization was achieved by using treatment (black and white poly bag) mulching materials with measurements of 105.10 cm and 103.20 cm, leaf area (54.72 cm2 and 46.09 cm2), soil temperature (31.87 ℃ and 31.90 ℃), soil moisture (8.10% and 8.27%), and plant yield (450 g,450 g). Rehabilitation (Control) Mulching material yielded the lowest results for plant height (83.10 cm), leaf number (71.50), leaf area (32.41 cm2), plant yield (200 g), soil temperature (31.16 ℃), and soil moisture (6.98%). In order to maximize crop output, growers of amaranthus in the research region are recommended to use either black or white poly bags.
