(Ediciones INTA, 2018-06-11)El propósito de esta publicación es exponer las tecnologías disponibles para mejorar los índices productivos de los sistemas de cría en la región NEA. Contiene 10 capítulos, donde se desarrollan las experiencias que ... -
Crop and tillage effect on water productivity of dryland agriculture in Argentina
(2013)Rising demands for food and uncertainties about climate change call for a paradigm shift in water management with a stronger focus on rainfed agriculture. The objective here was to estimate water productivity of different ... -
Crop diversification effects on soil organic carbon and nitrogen storage and stabilization is mediated by soil management practices in semiarid woody crops
(Elsevier, 2023-09)Crop diversification is a promising strategy to mitigate climate change through soil carbon sequestration while ensuring soil fertility maintenance and food security. Here, we assess the impact of different inter-cropping ... -
Crop diversity improves carbon, nitrogen and soil biological functions in an agroecological system = Diversidad de cultivos mejora el carbono, nitrógeno y las funciones biológicas del suelo en un sistema agroecológico
(Asociación Argentina de la Ciencia del Suelo, 2023-09-23)El manejo agroecológico está surgiendo como una alternativa prometedora al manejo agrícola actual, que se asocia con el deterioro de la calidad ambiental y la fertilidad del suelo. Por lo tanto, el objetivo de este estudio ... -
Crop intensification with sustainable practices did not increase N2O emissions
(Elsevier, 2020-04-15)Nitrous oxide (N2O) is the most important greenhouse gas produced by agricultural soils and is a byproduct of microbial nitrification and denitrification processes. The N2O emission rates depend on soil, climatic ... -
Crop management affects dry-milling quality of flint maize kernels
(Elsevier, 2011-05)Dry-milling performance of maize (Zea mays, L.) kernels primarily depends on their hardness. The flint type is harder than the dent and semi-dent maize, yielding a higher proportion of big endosperm pieces in the mill. ... -
Crop metabolomics : from diagnostics to assisted breeding
(Springer, 2018-11)Background Until recently, plant metabolomics have provided a deep understanding on the metabolic regulation in individual plants as experimental units. The application of these techniques to agricultural systems subjected ... -
Crop nitrogen status of early- and late-sown maize at different plant densities
(Elsevier, 2020)In maize (Zea mays L.) crops, nitrogen (N) status at silking (R1) has been used to predict grain yield (GY) response to N fertilization and to develop strategies to manage crop nutrition in order to match N supply with ... -
Crop rotations in the Rolling Pampas: characterization, spatial pattern and its potential controls
(Elsevier, 2020-04-30)One of the most important decisions made by farmers every year involves land allocation to different crops. Accurate information on crop sequences over large areas is a key prerequisite to address social concerns as soybean ... -
Crop sequence and P fertilization effects on soil P fractions under no-tillage
(Springer, 2021-05-27)Increasing cropping intensity may affect phosphorus (P) recycling through crop residue inputs, which may differ in soils with different productivity, P adsorption capacity, and P fertilization level. In three crop sequences: ... -
Crop species transferability of G-SSR and EST-SSR markers to Neltuma affinis spreng
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2024-03-18)Aim of study: To examine the transferability of G-SSR (genomic simple sequence repeats) and EST-SSR (expressed sequence tag simple sequence repeats) markers developed for several Neltuma species to N. affinis, a species ... -
Crop type and management are key filtering factors of functional traits in the weed communities of regions with contrasting soils and climates
(Wiley, 2021-11)Questions: Weed community composition responds to the interactions between environmental and management factors at different scales. The aim of this study was to disentangle the relative contributions of factors defining ... -
Crop-wild sunflower hybridization can mediate weediness throughout growth-stress tolerance trade-offs
(2017-11)Agricultural weeds are plants well-adapted to agricultural environments interfering directly and indirectly with crop production and causing important economic losses worldwide. Crop-wild hybridization is one of the main ... -
Cropland Net Ecosystem Exchange Estimation for the Inland Pampas (Argentina) Using EVI, Land Cover Maps, and Eddy Covariance Fluxes
(Frontiers Media, 2022-06-23)Estimations of Net Ecosystem Exchange (NEE) are crucial to assess the carbon sequestration/carbon source capacity of agricultural systems. Although several global models have been built to describe carbon flux patterns ... -
Cross transferability of SSR markers to endangered Cedrela species that grow in Argentinean subtropical forests, as a valuable tool for population genetic studies
(Elsevier, 2014-04)Species of Cedrela with a high economic value from Northwest and Northeastern Argentina are severely exploited. This work evaluates whether 51 nuclear SSRs, developed to study phylogenetically close species in the Meliaceae ... -
Cross transferability of SSRs to five species of Araucariaceae: a useful tool for population genetic studies in Araucaria araucana
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA) (España), 2011)Cross-species amplification of microsatellites is a common procedure to obtain suitable markers to be used in population genetic studies. Primers designed for one (source) species are used to amplify homologous loci in ... -
