Understanding the Diversity of the Angular Leaf Spot Pathogen to Improve Genetic Resistance in the Common Bean Host Crop

Common bean is an essential crop for food security in many regions of the world, but its production is constantly threatened by diseases such as angular leaf spot, caused by the fungus Pseudocercospora griseola. This pathogen is highly variable and has evolved alongside its host plant, the common bean, which makes its control and the development of resistant varieties more difficult. Understanding its genetic diversity is key to strengthening agricultural production.

Discovering the Life Cycle of Little-Known Insects

In tropical ecosystems, many species play key roles that we still do not fully understand. This is the case for some beetles, whose immature stages—larvae and pupae—have been little studied despite their ecological importance. Understanding their biology not only expands scientific knowledge, but also reveals connections with local practices and the sustainable use of natural resources.

Insects as a Sustainable Alternative in Poultry Feed

Given that production costs and input availability are increasingly affecting the poultry industry, there is a clear need to explore innovative and sustainable alternatives for animal feed. One of these options is the use of Hermetia illucens larval meal (black soldier fly), a highly nutritious ingredient that could partially replace traditional feed sources such as soybean and corn.

Coffee Innovation: Understanding Consumers Beyond What They Say

The coffee market is evolving rapidly, driven by new consumption trends and innovative products such as cold brew, a ready-to-drink beverage that has gained popularity for its smooth flavor and convenience. In this context, Eng. María Celeste Ortez, a graduate of the Agribusiness Engineering program, together with faculty members Martin Leal, M.Sc., Marvin Cálix, E.M.A., and Eng. Carlos Varela, conducted a study focused on analyzing the market potential of a Honduran cold brew coffee in Tegucigalpa by combining traditional tools and emerging technologies.

Attributes That Determine the Value of Specialty Coffee in Central America

In international markets, not all coffees are valued equally. Some achieve extraordinary prices at specialized auctions, while others are marketed as standard products. Understanding the factors that determine this value is key for producers, exporters, and consumers. In this context, Eng. Leopoldo Dimas, a graduate of the Agribusiness program at Zamorano, together with Marvin Cálix, E.M.A., Zamorano faculty member, and Dr. Luis Sandoval from Texas Tech University, conducted a study to analyze how specialty coffee prices are structured in Central America.

Data Intelligence to Understand Agricultural Markets

In a world where information is a key tool for decision-making, data analysis is transforming the way agricultural markets are understood. Eng. David Torres, a graduate of the Agribusiness Engineering program, under the supervision of Marvin Cálix, E.M.A., and Martin Leal, M.Sc., conducted a study focused on implementing business intelligence tools to analyze the behavior of agricultural products (commodities) in the United States market.

Combining soybean and tropical grasses to improve degraded soils 

Dr. Ricardo Peña, Associate Professor of Soils in the Department of Agricultural Science and Production, and his team of collaborators analyzed how different levels of nitrogen (N) applied to tropical pasture grasses and maize in a previous rotation affect the performance of a subsequent mixed cropping system of soybean with grasses in areas with degraded pastures.
