Latin Square Design: Basic Concept, Example, Demonstration in Agri Analyze and Quiz
This blog explains Latin Square Design basics like when to use design, how to perform randomization, ANOVA structure, solved example and demonstration in Agri Analyze platform. Link of quiz is given at the end. (Reading time 15-20 mins.) Latin Square Design (LSD) In agricultural field experiments, fertility gradients often run parallel to one side of the field. Occasionally, these gradients run parallel to both sides and in a new field, the predominant gradient direction may be unknown. In other words, when the experimental field is divided into smaller plots (experimental units), variation can occur in one direction, two directions, or exhibit cyclic variation in the case of a new field. In animal experiments, variation among experimental units can be influenced by characteristics such as age, growth, body weight, or lactation number. When variation is known for a single characteristic, local control can be applied by grouping experimental units into blocks or replicati...
