Multi-environment trials (METs) of crop genotypes are costly and require efficient test sites for cost effectiveness. This study aimed to identify efficient test sites for METs of sugarcane (Saccharum spp.) genotypes in Thailand, utilizing data from 10 sugarcane genotypes conducted at nine locations covering different sugarcane growing regions of the country for two crop-classes. Cluster an...

This study proposes an innovative two-sta-ge approach, using Data Envelopment Analysis and Biplot, to evaluate the techni-cal efficiency of 30 academic departments a Chilean university, identify main factors affecting their performan-ces. Public higher education worldwide is under growing pressure increase improve quality edu-cation with limited governmental funds given state-owned universities...

In cotton crops, the seed yield significantly contributes with success of any cultivar. However, other traits are considered when an ideotype is pointed out in selection, such as fiber quality traits. The aim this study was to applied genotype by yield*trait (GYT) biplot a multi-environment trial data genotypes and selected best genotypes. For end, thirteen from nineteen trials were assessed. S...

In an earlier investigation (Burger et al., 2000) five sediment cores near the Rodrigues Triple Junction in the Indian Ocean were studied applying classical statistical methods (fuzzy c-means clustering, linear mixing model, principal component analysis) for the extraction of endmembers and evaluating the spatial and temporal variation of geochemical signals. Three main factors of sedimentation...

There is an ever-increasing need to identify new feed resources in developing countries and the types of forages used tend to be more complex in terms of chemical composition. Near infrared re ̄ectance spectroscopy (NIRS) has the potential to aid the evaluation of forages and in this study was employed to compare and classify Gliricidia spp. provenances. Multivariate statistical techniques, incl...
