| Objective of this study is to characterize the impact of different injury profiles due to multiple pests and cultural practices on rice crop health and yields under irrigated conditions. The survey was conducted in NongKhai and Bueng Kan. The data sets collected from 96 fields included (I) nominal data set, which consists of soil types, rice varieties, and cultural practices, and (ii) ordinal data set, which consists of crop injuries due to insects, diseases and weeds, and rice yield. The data was analysed using various methods, i.e. non-parametric, multivariate statistic method, probability, cluster analysis, Chi-square distance and correspondence analysis. The results from cluster analysis based on multiple pest injury profiles (IP), farmer fields can be... |
