A socioeconomic and cost benefit analysis of Tropical Race 4 (TR4) prevention methods among banana producers in Colombia
https://hdl.handle.net/10568/158486
Abstract
The global banana industry faces a significant threat from Fusarium oxysporum f. sp. cubense Tropical Race 4 (TR4). While prior research has concentrated on TR4’s dissemination, reproductive conditions, and resistant banana varieties, this study employs a socioeconomic and cost-benefit analysis to explore the vulnerability of banana producers to TR4 in Colombia. It…

Simulating herbage and soil organic carbon under Urochloa hybrid cv. Cayman in Tanzania using the Decision Support System for Agrotechnology Transfer CROPGRO-Perennial Forage Model
https://hdl.handle.net/10568/179927
Abstract
The Cropping System CROPGRO-Perennial Forage Model (CROPGRO-PFM) within the Decision Support System for Agrotechnology Transfer (DSSAT) framework is among the few models that simulate and evaluate perennial forages. However, its application to systems in East Africa remains limited. To address this gap, this…

Virus‐inducible activation of hypersensitive response confers broad‐spectrum resistance to diverse viruses in plants
https://hdl.handle.net/10568/180226
Abstract
The hypersensitive response (HR) is a powerful plant defence mechanism that restricts pathogen spread through localised cell death. However, constitutive activation of HR can impair growth and development, limiting its utility in crop breeding and protection. In the study, we developed a virus‐inducible HR system by coupling an Avirulence/Resistance ( Avr/R ) gene pair, Avr4…

Proximity to natural habitat is not consistently associated with pollination services in tropical smallholder farms: A systematic review and meta‐analysis
https://hdl.handle.net/10568/178737
Abstract
ABSTRACT Proximity to natural habitat is known to enhance pollination services in large‐scale agriculture, but it remains unclear whether this holds in tropical smallholder farms. These systems are embedded in ecologically complex landscapes, central to global food security, and depend heavily on biodiversity‐derived ecosystem services.…

Long‐term cropping system and manure effects on soil health parameters and associated soil‐borne pathogens
https://hdl.handle.net/10568/179876
Abstract
Soil‐borne pathogens reduce the performance of key food crops in sub‐Saharan Africa. Diversified cropping and nutrient management can enhance soil and plant health, limiting pathogen damage. To examine how management and soil health changes influence soil‐borne pathogens, we leveraged an 18‐year field trial in western Kenya, evaluating cropping systems typical of smallholder farms. We…

Abstract
This article reviews the geographical distribution of wild common and lima beans in the Neotropics, their morphological and ecological attributes, and their biochemical and molecular variation along their ranges. These facts reveal the organization of the genetic diversity into three major gene pools, with one being…

Planthopper-rice interactions: unequal stresses on pure-line and hybrid rice under similar experimental conditions
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/51436
Abstract
Hybrid and pure‐line (inbred) rice [Oryza sativa L. (Poaceae)] varieties have distinct physiologies, particularly as related to their nutrient requirements. These differences could confound the results and interpretation of experiments that compare rice varieties grown in pots for their resistance and…

Abstract
Endophytic fungi often develop a systemic and mutually beneficial association with their hosts. A wide range of economically important plants have been reported to harbor endophytes. In these symbiotic mutualisms, both host and symbiont gain benefits from the association. The fungus obtains nutrients form its host and in return it provides…

Abstract
Digital soil mapping (DSM) permits continuous mapping soil types and properties through raster formats considering variation within soil class, in contrast to the traditional mapping that only considers spatial variation of soils at the boundaries of delineated polygons. The objective of this study was to compare the performance of SoLIM (Soil Land Inference Model) for…

Abstract
Tepary bean (<em>Phaseolus acutifolius</em> A. Gray) is more heat and drought tolerant than common bean (<em>P. vulgaris L.</em>). Four hundred mutant lines of two tepary accessions (G40068 and G40159) were generated by ethyl methane sulfonate (EMS) treatment. In preliminary studies of the M5 mutant lines under abiotic stress, three mutant lines (CMT…

Abstract
In an increasingly globalized world, invasive species cause major human, financial, and environmental costs. A cosmopolitan pest of great concern is the cassava mealybug Phenacoccus manihoti (Hemiptera: Pseudococcidae), which invaded Asia in 2008. Following its arrival, P. manihoti inflicted measurable yield losses and a 27% drop in…
