Special Issue Information

Dear Colleagues,

Scientific research in biological sciences, and especially, in agriculture, is a field that requires up-to-date methodological schemes both at the design and the statistical analysis stages of the experiments and studies. The efficient use of resources in agricultural research, as well as valid statistical analyses and inductive inferences, is always an important and “hot” issue that offers challenges for new research opportunities. Back in the early twentieth century, Sir Ronald Fisher, with his work at the Rothamsted Experimental Station (1919-1933), introduced the principles of experimentation in all applied sciences and created the foundations for modern statistical science. Nowadays, in the big data era, there is a plethora of multivariate and multidimensional data, data “cubes”, and a broad range of statistical and data analysis methods for managing and analyzing data arising in different branches of agricultural research. Thus, the aim of this Special Issue of Agronomy is to highlight the importance of and the opportunities for applied statistics in agricultural, biological, and environmental sciences. In addition, applications with new or improved methodological schemes and novel strategies in planning research, managing, analyzing, interpreting and visualizing data are currently of primary importance in the field. We welcome original research papers with methodological and/or statistical and/or data analysis orientation and content, systematic reviews, scoping reviews, and meta-analyses. We believe that there must be a balance between design and analysis, since both are equally important.

The Honeycomb Selection Design (HSD) is an innovative experimental method whose main feature is the even and systematic entry arrangement. Its systematicity, if combined with the absence of inter-plant competition that maximizes the phenotypic expression and differentiation of individual plants, enables the implementation of single-plant selection as early as the initial generations of genetic segregation, facilitating plant breeders to identify superior genotypes. Due to the specificity of entry allocation and the complexity of statistical data analysis, a specialized software becomes necessary. This article provides a detailed presentation of the ‘rhoneycomb’, a free and open-source R package concerning the construction, visualization, and analysis of HSDs. Full article

Technical efficiency is considered a useful advisory tool for managers whose main goal is to maximize profit and minimize costs. Data envelopment analysis is a widely accepted methodology for technical efficiency estimation in the sector of agriculture. For that reason and with the view to extract useful conclusions regarding farmers’ effective management of inputs, this study aims to present the DEA method through its implementation in a set of farms located in the regional unit of Pieria. To conduct this analysis, relevant data were collected through a survey in which 40 farms participated. The output variable was chosen to be each farm’s total amount of sales, while the inputs were selected in a way to represent the main factors of production, such as (1) land in acres, (2) labor in hours, and (3) variable costs in EUR. The results showed that the examined farms need to reduce the inputs used by 34.6% to operate more efficiently from the point of view of the CRS model. Therefore, farmers should be motivated to reduce the inputs used, something that can be done through the provision of specialized advisory services. This will, of course, be helped by both the local authorities and the policies of the country in which the rational use of inputs seems to be necessary. This study may contribute to the relevant literature, agriculture, and the area since management suggestions are formulated for the farmers of Pieria’s regional unit. Full article

Block Kriging (a spatial interpolation method) and log10 transformation were compared for their effectiveness in reducing relative variance (coefficient of variance: CV) and estimate mean values in all harvested maize plants grown in three randomly taken field plots and for harvested plants after removing the “edge or margin” ones. The results showed that log10 transformation reduced CVs of all harvested original fresh weight (FW) plant data in the three plots from 35.6–41.6% (original data) to 6.0–7.5%, while the respective CVs due to Block Kriging were reduced to 14.5–19.9%. The back-log10-transformed means of all harvested FW plant data were reduced by 6.8–9.4%, while the respective reduction for plants excluding the margin ones was 1.3–8.3%. The Block Kriging means for all harvested FW plant data were reduced only by 0.3–0.4%, while the respective means of the harvested plants excluding margin ones were increased by 0.4–4.3%. These findings strongly suggest that Block Kriging should be preferred over the log10 transformation method (used so far by agroscientists) as it managed to effectively reduce variability in crop data and estimate missing values that provide more precise and reliable estimates of corn yield for farmers.
