La biodiversidad es un recurso indispensable ya que está íntimamente ligada a las actividades y necesidades cotidianas delhombre como la alimentación, salud, vivienda y protección, transporte, entre otros aspectos, por lo cual la conservacióny el manejo del entorno natural son claves para el desarrollo de una sociedad y su cultura. Actualmente existen grandesproblemas ambientales que afectan la biodiversidad en el planeta, entre ellos el tráfico y comercio ilegal de animalessilvestres, reducción y fragmentación de hábitats, sobreexplotación de los recursos, especies exóticas y la polución. Todosestos factores representan un riesgo para la fauna y la biodiversidad global en los países megadiversos, de los cuales lamayoría pertenecen al continente americano. En este artículo de revisión se hace un recuento de los esfuerzos del hombrepara manejar de manera sostenible la faun...

Strawberry cultivation holds significant economic and social promise within Peruvian fruit production. However, conventional management practices have led to the excessive use of agrochemicals in this crop. This study proposes an organic approach to strawberry production, integrating less environmentally harmful technologies. The aim was to assess microbial inoculation by using Trichoderma sp. and Pseudomonas putida and the application of organic amendments on strawberry seedlings of the commercial cultivar “San Andreas”. A field experiment was established with evaluations in the vegetative and productive stages. Results indicate that the co-inoculation of Trichoderma sp. and Pseudomonas putida increased leaf area by 7%, and enhanced the aerial part’s fresh and dry biomass by 13% and 28%, respectively, compared to treatment without microbial inoculation. Concurrently, compost appli...

Durum wheat (Triticum durum Desf.) underpins semolina value chains in water-limited regions, yet Peru remains import-dependent due to constrained local adaptation. We evaluated eleven elite lines plus the commercial variety 'INIA 412 Atahualpa' across three contrasting semi-arid sites in Arequipa (Santa Elena, San Francisco de Paula, Santa Rita) during 2023–2024 to identify genotypes maximizing performance and stability. Grain yield, thousand-kernel weight (TKW), hectoliter weight, and plant height were analyzed with combined analysis of variance (ANOVA), the additive main effects and multiplicative interaction (AMMI) and genotype and genotype-by-environment (GGE) biplots, complemented by AMMI stability value (ASV) and weighted average of absolute scores and best yield index (WAASBY). Grain yield and hectoliter weight showed significant genotype × environment (G × E) interaction, whi...

Strawberry cultivation requires strategies that maintain or improve its yield within a scheme in which reducing fertilizers and other chemical products can make its consumption safer and more environmentally friendly. This study aims to evaluate the effect of Bacillus subtilis and Rhizophagus intraradices on strawberry growth, yield, and fruit quality. B. subtilis and R. intraradices were inoculated and co-inoculated under three fertilization levels of 225-100-250, 112-50-125, and 0-0-0 kg・ha−1 of N, P2O5 and K2O. Vegetative growth was evaluated in plant height (cm), leaf area (cm2), aerial fresh weight (g), aerial dry weight (g), and plant coverage (%) variables. Fruit quality parameters such as total acidity (g・100 mL−1), soluble solids (Brix◦), and firmness (kg) were also determined, as well as the number of fruits per m2 and yield (t・ha−1). The results showed that the p...

Potato production in the Andean highlands demands strategies that reduce dependence on synthetic inputs without sacrificing yield. We evaluated two microbial bioinputs—Bacillus subtilis and Trichoderma viride—applied once pre-plant to seed tubers, under three organo-mineral fertilization regimes (0%, 50%, and 100% of the recommended NPK rate) in two cultivars (INIA 303-Canchán and Yungay) in field conditions in Ayacucho, Peru, using a randomized complete block, split-plot design (three replicates). Agronomic traits (plant height, root dry weight, stems per plant, tubers per plant, and plot-level yield) were analyzed with robust two-way ANOVA and multivariate methods. Combining microbial inoculation with 50% NPK sustained growth responses comparable to 100% NPK for key traits: in Yungay with T. viride, plant height at 50% NPK (≈96.15 ± 1.71 cm) was not different from 100% NPK (≈...
