Analysis Of Different Levels of Composted Poultry Litter on Growth and Yield of Amaranthus in Owo. Ondo State
Abstract
This study evaluated the effects of different levels of compost manure on the growth and yield of Amaranthus hybridus in Owo, Ondo State, Nigeria. The experiment was conducted in 2025 at the Teaching and Research Farm of Rufus Giwa Polytechnic, using a Randomised Complete Block Design (RCBD) with four treatments: 0, 5, 10, and 15 t/ha of compost manure, each replicated three times. Proper soil analysis before planting indicated sandy clay loam, slightly acidic and low in essential nutrients. Data were collected on soil physical properties, plant height, number of leaves, number of nodes, stem girth, and fresh and dry weights, and analysed using Analysis of Variance (ANOVA) with Duncan Multiple Range Test (DMRT) at 5% significance level. Results showed that compost manure significantly improved soil physical properties by reducing bulk density and temperature while increasing porosity and moisture content. Growth and leaf yield of Amaranthus hybridus were significantly enhanced with increasing compost levels. The highest values for plant height, leaf number, number of nodes, stem girth, and biomass yield were recorded at 10 and 15 t/ha, with no significant difference between these two rates in most cases. The poor performance observed in the control treatment was attributed to low soil fertility. The study concludes that composted poultry manure at 10–15 t/ha optimises the growth and yield of Amaranthus hybridus under the agroecological conditions of Owo. The use of compost manure is therefore recommended as a sustainable and environmentally friendly soil fertility management practice for vegetable production.
