Exploring farmer perceptions of agricultural innovations for maize-legume intensification in the mid-hills region of Nepal
(Taylor & Francis, 2018)Maize-legume intercropping is a fundamental component of mixed farming systems in the mid-hills of Nepal. However, its productivity is constrained by several biophysical and social factors, and limited adoption of proven ... -
Exploring gene networks in two sunflower lines with contrasting leaf senescence phenotype using a system biology approach
(BMC, 2019-10)Background: Leaf senescence is a complex process, controlled by multiple genetic and environmental variables. In sunflower, leaf senescence is triggered abruptly following anthesis thereby limiting the capacity of plants ... -
Exploring nitrogen limitation for historical and modern soybean genotypes
(American Society of Agronomy, 2018-10)The United States (USA) and Argentina (ARG) account for over 50% of the global soybean [Glycine max (L.) Merr.] production. Soybean N demand is partially met (50–60%) by the biological nitrogen fixation (BNF) process; ... -
Exploring nutrient-sensitive landscape configurations for rural communities in southern Mexico
(Elsevier, 2024-06)In Mexico, the traditional MILPA polycropping system is giving way to maize monocultures, impacting the nutritional diversity of smallholder farmers and diminishing ecosystem services. This study explores landscape ... -
Exploring opportunities for diversification of specialized tobacco farms in the Northwest of Argentina
(Wageningen University, 2012)In the Northwest of Argentina tobacco (Nicotiana tabacum L.) is economically and socially important. Tobacco mono-cropping, excessive tillage and inadequate irrigation management cause soil degradation. This and also tobacco ... -
Exploring Soil Bacterial Diversity in Relation to Edaphic Physicochemical Properties of High-altitude Wetlands from Argentine Puna
(Springer, 2024-01)High Andean wetlands, particularly those known as vegas or bofedales, are essential conservation ecosystems due to their significant contribution to ecosystem services. The soil microbial communities in these ecosystems ... -
Exploring solution spaces for nutrition-sensitive agriculture in Kenya and Vietnam
(Elsevier, 2020-04)Smallholder agriculture is an important source of livelihoods in South Asia and sub-Saharan Africa. In these regions the highest concentrations of nutritionally vulnerable populations are found. Agricultural development ... -
Exploring species composition and population dynamics of thrips (Thysanoptera: Thripidae) in peanut crops in Argentina
(Springer, 2021-04-26)Thrips (Thysanoptera: Thripidae) are major pests of peanut (Arachis hypogaea L.). They cause feeding damage and indirect injuries transmitting plant viruses. In Argentina, peanut is commonly affected by thrips. The crop ... -
Exploring sunflower responses to Sclerotinia head rot at early stages of infection using RNA‑seq analysis
(Springer Nature, 2020-08)Sclerotinia head rot (SHR), caused by the necrotrophic fungus Sclerotinia sclerotiorum, is one of the most devastating sunflower crop diseases. Despite its worldwide occurrence, the genetic determinants of plant resistance ... -
Exploring the ancestral mechanisms of regulation of horizontally acquired nitrogenases
(Springer, 2015-10)The vast majority of Pseudomonas species are unable to fix atmospheric nitrogen. Although several studies have demonstrated that some strains belonging to the genus Pseudomonas sensu stricto do have the ability to fix ... -
Exploring the association between polymorphisms at 3’UTR SLC11A1 gene microsatellites and resistance to tuberculosis: A case-control study in Bos taurus dairy cattle
(2018-04)Bovine tuberculosis is a contagious infectious disease that causes significant economic impact in dairy and meat farms throughout the world. Multiple factors, including host genome, determine the outcome of the infection. ... -
Exploring the biological activity of condensed tannins and nutritional value of tree and shrub leaves from native species of the Argentinean Dry Chaco
(2017)BACKGROUND: Tropical tree or shrub leaves are an important source of nutrients for ruminants and a potential source of biologically active compounds that may affect ruminalmetabolism of nutrients. Therefore, eightwoody ... -
Exploring the diversity of alfalfa within Brazil for tropical production
(Springer, 2020-04-15)Alfalfa (Medicago sativa L.) is a forage legume of great interest because of its role in milk production schemes. Although it has the potential to be cultivated in different edaphoclimatic regions, the fodder production ... -
Exploring the diversity of the root-associated microbiome of Ilex paraguariensis St. Hil. (Yerba Mate)
(2017)Ilex paraguariensis St. Hil. (Yerba Mate) is an important crop for which a decrease in yields associated to unsustainable agricultural practices is well documented. The aim of this study is to investigate the diversity of ... -
Exploring the ecological and evolutionary relationships between Rickettsia and hard ticks in the Neotropical region
(Elsevier, 2021-06)This study addresses a meta-analysis of the distribution of Rickettsia spp. in the Neotropical region, as well as their associations with ticks and vertebrates. A total of 219 published reports on Rickettsia in ticks in ... -
Exploring the factors involved in the absence of parasitism of Chaetosiphon fragaefolii by generalist parasitoids in strawberry
(Springer, 2020-08)Chaetosiphon fragaefolii Cockerell (Hemiptera: Aphididae) is a worldwide strawberry pest with scarce records of parasitoids for its control. The parasitization rate of two generalist parasitoids, Aphidius colemani Viereck ... -
