N:P:S stoichiometry in grains and physiological attributes associated with grain yield in maize as affected by phosphorus and sulfur nutrition
(2017-03)Balanced nutrition is necessary to reduce yield gaps in maize. Simultaneous phosphorus (P) and sulfur (S) deficiencies may be present in soils, so a P × S interaction is expected. In maize, yield is closely related to grain ... -

(2014-01)The spectrum of entomophthoroid fungal species parasitising aphids on cereal crops and a study of the phenology and prevalence of these pathogens were investigated in Argentina. The studies were conducted at six different ... -
Natural occurrence of entomophthoroid fungi of aphid pests on Medicago sativa L. in Argentina = Ocurrencia natural de hongos entomophthorales de áfidos plaga de Medicago sativa L. en Argentina
(2014-03)Four species of entomophthoroid fungi, Pandora neoaphidis (Entomophthorales: Entomophthoraceae), Zoophthora radicans (Entomophthorales: Entomophthoraceae), Entomophthora planchoniana (Entomophthorales: Entomophthoraceae) ... -
Nellore cattle (Bos indicus) and ticks within the Brazilian Pantanal: ecological relationships
(2016-02)Pantanal is a huge floodplain mostly in Brazil, and its main economic activity is extensive cattle raising, in farms characterized by an extremely wildlife-rich environment. We herein describe tick infestations of cattle ... -
Neospora caninum truncated recombinant proteins formulated with liposomes and CpG-ODNs triggered a humoral immune response in cattle after immunisation and challenge
(Elsevier, 2021-06)Abortions caused by Neospora caninum are a serious problem in cattle production and require effective immunoprophylaxis. The objective of this work was to assess the humoral immune response to four recombinant (r) N. caninum ... -
Neosporosis bovina en Argentina: a 25 años del primer reporte en el país
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata, 2021)La neosporosis es una enfermedad de gran impacto en el ganado vacuno debido a que causa abortos en el segundo y último trimestre de la gestación. En esta revisión se resume y discute la información sobre la misma, recopilada ... -
New insights into soybean biological nitrogen fixation
(American Society of Agronomy, 2018-08)Soybean biological N2 fixation (BNF) relationships with fertilizer N and yield response have been comprehensively reviewed in the scientific literature. However, the study of the N-gap between N uptake and N supplied by ... -
New records and host associations of the tick Ixodes apronophorus and the first detection of Ehrlichia sp. HF in Romania
(2018-04)Ixodes (Ixodes) apronophorus is a neglected tick species and its geographical distribution, host associations, and role as a disease vector are not well known. We collected I. apronophorus from several locations in Romania. ... -
A new sunflower high oleic mutation confers stable oil grain fatty acid composition across environments
(2016)The oil industry demands sunflower oils with high oleic acid content. New varieties producing high oleicoils independently of the growing environment are needed as growers could receive an extra prime foroffering them. Oil ... -
Niche divergence among closely related taxa provides insight on evolutionary patterns of ticks
(Wiley, 2021-09)Aim: Understanding the degree to which closely related taxa diverge in their niche traits could provide insight on their evolutionary patterns, as well as shed some light on the mechanisms underpinning broad-scale biogeographic ... -
Nitrogen and sulfur interaction on nutrient use efficiencies and diagnostic tools in maize
(Elsevier, 2020-05)Nitrogen (N) and sulfur (S) critical dilution curves and the N:S stoichiometry are useful tools for evaluating nutrient status in maize (Zea mays L.). Nutrient supply for both N and S impact plant nutrient uptake, consequently ... -
Nitrogen balance in a plant-soil system under different cover crop-soybean cropping in Argentina
(2018-10-10)Cover crops (CC) provide many benefits for the soil and the following crop but their effects on nitrogen (N) release and balance in continuous no-tillage soybean (Glycine max L. Merr.) production are little known. Estimation ... -
Non-parasitic life cycle of the cattle tick Rhipicephalus (Boophilus) microplus in Panicum maximum pastures in northern Argentina
