To improve the efficacy of experiments, various aspects of efficient experimental field design, analysis and data management with the aid of modern statistical software was the focus of a five-day training course that was specially designed for National Agricultural Research System (NARS) partners in Nigeria.
Topics covered included generation and analysis of replicated and non-replicated trials, data cleaning, curation, single site and genotype-environment interaction (GxE) analysis and interpretation. Participants were trained to use GenStat 17th edition and introduced to Breeding Management System of Integrated Breeding Platform.
Participants were oriented on principles of experimental design, such as blocking, randomization, replication and other practical field applications such as field gradient control, controlling border effect and appropriate data recording mechanism using Android-based handheld devices. Participants worked with their own data sets and discussed results with the whole group.
A half-day field visit to experimental fields at Minjibir research station located 45 km north of Kano was organized to understand practical aspects of good experimental design.
The course on Design of Experiments and Statistical Analysis of Multi-Environment Trials (GxE) and Use of GenStat was organized at ICRISAT from 27 to 31 July. The course was attended by 26 participants including NARS scientists, scientific officers, technicians and research scholars from Nigeria. The course was organized by Breeding Informatics Unit, ICRISAT.
The training was part of the Nigeria Sorghum and Groundnut Value Chain project supported by Federal Government of Nigeria. The activity was undertaken as part of CGIAR Research Programs on Dryland Cereals and on Grain Legumes
