Potential for crop production increase in Argentina through closure of existing yield gaps
(Elsevier, 2015-12)Favorable climate and soils for rainfed crop production, together with a relatively low population density, results in 70–90% of Argentina grain production being exported. No assessment to date has tried to estimate the ... -
Potential of rhizobacteria native to Argentina for the control of Meloidogyne javanica.
(Asociación Argentina de Microbiología, 2021-05-02)Biocontrol of the nematode Meloidogyne javanica was studied using the Argentinean strains Pseudomonas fluorescens MME3, TAE4, TAR5 and ZME4 and Bacillus sp. B7S, B9T and B19S. Pseudomonas protegens CHA0 was used as a ... -
Potential, attainable, and current levels of global crop diversity
(IOP Publishing, 2022-04-04)High levels of crop species diversity are considered beneficial. However, increasing diversity might be difficult because of environmental constraints and the reliance on a few major crops for most food supply. Here we ... -
Pre-harvest strategy for reducing aflatoxin accumulation during storage of maize in Argentina
(Elsevier, 2022-08-27)Maize (Zea mays L.) is an important crop in Argentina. Aspergillus flavus may infect this crop at growing stage and the harvested kernels can be contaminated with aflatoxins (AFs), whose levels may increase during storage. ... -
Predicción de contenido de arcilla superficial utilizando conductividad eléctrica aparente y esquemas de muestreo basados en modelos
(2017)La predicción espacial del contenido de arcillas (As) a escala de lote es requerida para la implementación de agricultura de precisión y modelos de simulación hidrológica. Sin embargo, la brecha de técnicas de cartografía ... -
Predicting maize phenology: intercomparison of functions for developmental response to temperature
(American Society of Agronomy, 2014-12)Accurate prediction of phenological development in maize (Zea mays L.) is fundamental to determining crop adaptation and yield potential. A number of thermal functions are used in crop models, but their relative precision ... -
Predicting soybean losses using carbon dioxide monitoring during storage in silo bags
(Elsevier, 2019-06)The rapid increase of the overall grain production of Argentina resulted with a storage capacity deficit in permanent structures of 40–50 million tons, and this context favored the rapid adoption of the silo bag technology. ... -
Prediction of topsoil properties at field-scale by using C-band SAR data
