In this short video, Ric Coe introduces the concepts of options by context interactions by describing the more standard “genotype by environment” interactions that plant breeders use, and then generalising the idea.
This video discusses some of the issues surrounding the design of experiments when considering options by context interactions, including how to decide what ‘options’ to test, and the contexts in which to test them.
Communication is vital when conducting experiments with farmers. This video discusses some of the issues of how, why and particularly what to communicate when working with farmers. We also make the case for a detailed written protocol to communicate the details of the design to yourself and others. Written by Ric Coe Designed by Emma […]
Replication is often a point of confusion for researchers. Often, researchers conducting on-farm trials will simply say “the farms / farmers are my replicates” and leave it at that. This video discusses why this is not a good idea, and why you need to think more carefully about where your replicates are in your design […]
This video gives some examples of how to look at data from on-farm trials in a slightly different way, enabling you to get more information from the data. We also discuss how to design your trial to make it as easy as possible to get useful and relevant information from the results. Written by Ric […]
Enset (Ensete ventricosum (Welw.) Chessman is a perennial, herbaceous and monocarpic crop belonging to the family Musaceae. Enset is an orphan and little researched food crop cultivated only in Ethiopia. The project was initiated with the overall objective of improving food security, income and livelihood of enset farmers through integrated enset bacterial wilt management and […]
