Economía agraria [PDF]

open access: yes, 2010
La producción agropecuaria en Nicaragua, tanto para consumo interno, como para la exportación se ha estancado en los últimos veinte años. Ello indica que los niveles de productividad se han deteriorado en ese importante sector de la economía nacional.

High phylogenetic turnover magnifies evolutionary relatedness along bacterial primary succession

open access: yesEcology, Volume 107, Issue 6, June 2026.
Abstract Current models of microbial primary succession postulate that stochasticity dominates the early stages of soil community assembly, generating phylogenetically random patterns that are lost as abiotic and biotic filters gain relevance. We hypothesized that, under severe environmental stress, abiotic filters may override stochasticity from early

Morphological, Culinary, and Nutritional Diversity of Common Bean (Phaseolus vulgaris) Accessions in the Northern Andean Region of Peru

open access: yesLegume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Common bean (Phaseolus vulgaris L.) grains represent a major source of plant‐based protein and essential micronutrients; however, their consumption is constrained by prolonged cooking times and variable nutritional profiles. This study characterized the morphological, culinary, and nutritional diversity of 36 common bean accessions collected ...

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

open access: yesPest Management Science, Volume 82, Issue 6, Page 5184-5194, June 2026.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

open access: yesPest Management Science, Volume 82, Issue 6, Page 5757-5766, June 2026.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Association of Agro‐Morphological Traits With Cup Quality in Accessions of Coffea arabica L. From the INIA Germplasm Bank, Peru

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT In recent years, Peruvian coffee production has increasingly focused on specialty coffees, with cup quality (CQ) as a key criterion. While previous studies have characterized the Coffee Germplasm Collection of the National Institute of Agrarian Innovation (CGC‐INIA), few studies have analyzed coffee cup quality.

Genetic control of wheat flour end‐use quality and rheology by genome‐wide association studies

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Improving end‐use quality in bread wheat (Triticum aestivum) requires dissecting the genetic basis of complex processing traits and deploying robust prediction pipelines in breeding. We performed genome‐wide association studies (GWASs) using 1767 high‐quality single‐nucleotide polymorphisms generated by genotyping‐by‐sequencing in a diverse ...

Phenotypic and genetic resistance to Septoria blotch disease in European wheat varieties

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Zymoseptoria tritici, the causal agent of Septoria tritici blotch (STB), poses a critical threat to wheat (Triticum aestivum L.) production in temperate Europe, underscoring the need for durable genetic resistance. Here, we screened 151 winter wheat varieties at the seedling stage using a mixed inoculum of five virulent isolates.
