(Springer, 2013-06)This work estimates the economic losses due to Neospora abortions in the humid pampa region of Argentina. The total dairy and beef cattle population at risk of abortion is 1,771,326 and 9,726,684 head, respectively. In ... -
Neospora caninum serostatus is affected by age and species variables in cohabiting water buffaloes and beef cattle
(Elsevier, 2014-07-14)The aim of this study was to investigate how Neospora caninum serostatus may be affected by variables such as host species (water buffaloes or cattle) and age in animals cohabiting in the same ranch. A convenience ... -
Neosporosis epidémica y endémica: descripción de dos eventos en bovinos para cría = Endemic and epidemic bovine neosporosis: description of two events in beef cattle
(Elsevier, 2014-12)El objetivo de este trabajo es describir dos eventos producidos en la provincia de Buenos Aires en los cuales Neospora caninum estuvo asociado a la ocurrencia de abortos en bovinos de cría para carne. En uno de ellos se ... -
New insights into wood anatomy and function relationships: how Eucalyptus challenges what we already know
(Elsevier, 2019-12-15)Multispecies surveys have shown that there is a weak but significant trade-off between xylem efficiency and safety in woody species, with no species maximizing both attributes at the same time. Relationships between xylem ... -
Nitrato en pecíolo e índice verde en estratos del canopeo del cultivo de papa
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-08)La concentración de nitrato en los pecíolos (NBS) y el Índice Verde (IV) medidos en las hojas inferiores del canopeo de papa podrían usarse como alternativa de los métodos tradicionales de evaluación del estado nutricional ... -
Nitrogen balance for potato crops in the southeast pampas region, Argentina
(Springer, 2013-01)The aim of this work was to build an N mass balance for the potato crop under irrigation conditions in the southeast pampas (Argentina) as a function of N rate and gravitational water. The experiment was developed in a ... -
Nitrogen Recovery Efficiency from Urea Treated with NSN Co-Polymer Applied to No-Till Corn
(MDPI, 2018-08-19)Nitrogen (N) rate increases used by many farmers produce a reduced or null effect on N recovery efficiency (RE) by crops. Therefore, management practices to reduce N losses and increase RE are necessary. Co-polymer maleic ... -
