Growth and Yield Response of Amaranthus (Amaranthus caudatus) to Organic Manure (Cow Dung) in Anyigba, Dekina LGA of Kogi State, Nigeria

The study was conducted at Prince Abubakar Audu University Research and Demonstration Farm, Anyigba, during the 2022 rainy season. The objective of the study was to evaluate the effects of rate of cow dung manure application on the growth and yield of Amaranthus. (Amaranthus caudatus). Randomized Complete Block Design (RCBD) was used in the experiment and was replicated three (3) times. The treatment consisted of six (6) varying levels of organic manure, i.e. six (6) treatments and three (3) replications which resulted to a total of eighteen (18) plots. The parameters measured includes: plant height (cm), number of leaves per plant, leaf area per plant (cm), shoot weight (g) and root weight (g). From the result obtained, it was obvious that Amaranthus was influenced by Application of cow dung manure at of (648 g/plot) gave the highest yield for almost all the growth and yield characters such as plant height, number of leaves, leaf area and root weight of plant. While (324 g) also have the highest for shoot weight alone. Since (648 g) and (324 g) of cow dung had the highest growth and yield results, Amaranthus farmers in Anyigba environment should lay their hands on cow dung as their nutrient source for application to Amaranthus crop to influences the growth and yield.
