Research studies the impacts of multiple pest injuries on rice crop health and yield grown under irrigated ecosystem with different cultural practices in Surin province. Data sets were collected from 75 farmers' fields and analysed using non-parametric multivariate statistical method, probability, cluster analysis, Chi-square distance analysis, and correspondence analysis. Data sets included soil properties, irrigation system, rice cultivars, cultural practices, yields, crop damages due to insects, diseases, and weeds. The results from a cluster analysis based on multiple pest injury profiles (IP), farmer fields could be classified into 4 groups; IP1, IP2, IP3, and IP4, with the number of members of 71, 2, 1, and 1, respectively.
