Evaluation efficiency of severity of angular leaf spot in common bean based on diseased and healthy leaf area.

This study compared severity of angular leaf spot in common bean lines, based on the healthy and diseased leaf area, and the graded scale. We used 12 common bean lines in the dry and rainy seasons. Two contiguous experiments were conducted in each season, with and without chemical control of the pathogen. We evaluated the percentage of the healthy and diseased leaf area; severity based on a graded scale and the area under the disease progress curve; and yield. The diseased or healthy leaf area is efficient to evaluate the severity of angular leaf spot with a sample of 20 to 30 leaflets per plot. For all traits, the results of central and border areas did not differ, indicating that the evaluation of border rows is unnecessary and, finally, the severity assessment of the upper plant half can discriminate the lines more efficiently

Exploring the Applicability of the Science Communication Research Agenda to Agricultural Communications Scholarship

Agricultural communications scholars do not use a national research agenda to guide their research, which could be limiting the impact and rigor of the discipline. In this commentary, we argue that agricultural communications scholars should adopt the science communication research agenda published by the National Academies of Sciences, Engineering, and Medicine in 2017 because the goals of science communication, outlined in the agenda, are relevant to agriculture. Members of the committee who developed the agenda study science communication in contexts of food, agriculture, life sciences, the environment, political science, health, nutrition, and psychology, among others. They developed the agenda with the intent for it to inform and guide research in all science communication sub-disciplines or areas involving contentious public issues. We provide examples of studies that have used the agenda to inform research in agricultural and natural resources communications. We also explain how research priorities outlined in the science communication research agenda align with agricultural communications scholarship. Recognizing there are challenges unique to agriculture, we recommend agricultural communications scholars use the science communication research agenda as a research guide and adapt the relevant research recommendations for agricultural communications
