Assessing soil P fractions changes with long‐term phosphorus fertilization related to crop yield of soybean and maize
(Wiley, 2020-02)Long-term P fertilization increases soil phosphorus (P) labile fractions, which can be associated with crop P uptake and grain yield and are useful to improve fertilizer recommendations. Research aims were to evaluate in ... -
Contribution of honeybees to soybean yield
(Springer, 2018-02)Despite the economic importance of soybean [Glycine max (L.) Merr.], knowledge on the contribution of entomological pollination on seed yield is scarce. This study estimates the production of soybean resulting from pollination ... -
Conyza bonariensis as an alternative host for Colletotrichum species in Argentina
(Wiley, 2020-10)Aims: This study investigated the diversity of Colletotrichum isolates recovered from Conyza bonariensis leaves through the use of morphological characteristics, growth rate, carbon sources utilization and phylogenetic ... -
Current status of soybean anthracnose associated with Colletotrichum truncatum in Brazil and Argentina
(MDPI, 2019-10)Brazil and Argentina have a combined soybean area of 53.6 million hectares, which accounts for over half of the total global production. The soybean crop in South America extends from latitude 8–10 S to 32–36 S. Such a ... -
Defining soybean maturity group options for contrasting weather scenarios in the American Southern Cone
(Elsevier, 2022-10)Soybean genotypes are grouped in maturity groups (MG) based on the response to photoperiod, and a genotype belonging to a particular MG is recommended according to latitude and planting date. From an agronomic viewpoint, ... -
Defoliation affects soybean yield depending on time and level of light interception reduction
(Southern Cross Publishing, 2012-07)Light interception (mainly due to defoliation) during the critical growth periods of soybean may be a suitable index for calculating the economic injury level (ELI) rather than measuring the insect population or percentage ... -
Desarrollo de un método para evaluar el daño ocasionado por aves en cultivos comerciales de soja recién emergida = Development of a method for assessing damage caused by birds in sprouting soybean in commercial crops
(Facultad de Ciencias Agronómicas, Universidad de Tarapacá, Chile, 2016-12)El cultivo de soja (Glycine max) es uno de los principales rubros productivos en Sudamérica. Algunas especies de aves pueden consumir los cotiledones de las plántulas de soja recién emergidas causando daño al cultivo. Con ... -
¿Eligen las palomas y cotorras los lotes de soja (Glycine max) enemergencia? Un caso de estudio en agroecosistemas de Entre Ríos, Argentina = Do pigeons and parakeets choose soybean (Glycine max) crops during the emergence? A case studyon agroecosystems in Entre Ríos, Argentina
(Instituto de Biología, Universidad Nacional Autónoma de México, 2016-12)Las palomas y cotorras pueden resultar perjudiciales para cultivos anuales en algunas regiones de Sudamérica. En este estudio analizamospatrones de uso de hábitat de las palomas torcaza (Zenaida auriculata), manchada ... -
Field availability and avoidance of imidacloprid-treated soybean seeds and cotyledons by birds
(Wiley, 2023-02)Treated seeds and their cotyledons can present a toxicological risk to seed-eating birds. To assess whether avoidance behavior limits exposure and consequently the risk to birds, three fields were sown with soybeans. Half ... -
Highly diverse and rapidly spreading: Melanagromyza sojae threatens the soybean belt of South America
(Springer, 2021-02)The soybean stem fly, Melanagromyza sojae, an Asian native insect, has successfully established in Brazil, Argentina, Paraguay and Bolivia. These countries are among the lead global soybean producing nations, being ... -
Identification of Molecular Markers and Candidate Genes Associated with Time to Flowering and Length of Reproductive Period in Soybean Through Association Mapping
(Springer, 2023-06)Adaptation to temporal stress can be achieved by modifying flowering time and lengthening the reproductive period. To identify genotypes, molecular markers, and genes related with these traits, a set of 94 soybeans were ... -
Improving resource productivity at a crop sequence level
(Elsevier, 2019-04)The challenge to increase agricultural production with a minimum environmental impact requires to reach the maximum efficiency in the capture and use of resources such as photosynthetically active radiation (PAR), water, ... -
Long-term fertilizer application and cover crops improve soil quality and soybean yield in the Northeastern Pampas region of Argentina
(Elsevier, 2021-03)Long-term improvements in soil quality through cover crops (CC) and fertilizer management may provide resilience for temporal water stresses in cropping sequences based on soybean [Glycine max (L.) Merr.]. The objectives ... -
Modelling long-term effects of cropping intensification reveals increased water and radiation productivity in the South-eastern Pampas
(Elsevier, 2013-08)Wheat/soybean double crop provides a reliable platform for cropping intensification in many subtropical and temperate areas, even in those with a short growing season as the South-eastern Pampas of Argentina. However, the ... -
Optimizing resource productivity in soybean-based sequences through long-term crop intensification
(Elsevier, 2023-10)Context: Cropping systems based on a single crop per year, such as soybean monoculture, result in an inefficient use of available resources and low productivity, and are usually related with a negative environmental impact. ... -
Pathogenicity of Fusarium graminearum and F. meridionale on soybean pod blight and trichothecene accumulation
(Wiley, 2016-12)Soybean (Glycine max) is the most important crop in Argentina. At present Fusarium graminearum is recognized as a primary pathogen of soybean in several countries in the Americas, mainly causing seed and root rot and pre‐ ...
