Use of a critical phosphorus dilution curve to improve potato crop nutritional management
(Springer, 2016-08)Plant diagnostic methods to determine P deficiencies need the definition of a critical concentration value which represents the minimum P concentration required to achieve maximum growth. The critical P concentration (Pc) ... -
Use of easy measurable phenotypic traits as a complementary approach to evaluate the population structure and diversity in a high heterozygous panel of tetraploid clones and cultivars
(Springer Nature, 2018-01-16)Background: Diversity in crops is fundamental for plant breeding efforts. An accurate assessment of genetic diversity, using molecular markers, such as single nucleotide polymorphism (SNP), must be able to reveal the ... -
Use of geophysical survey as a predictor of the edaphic properties variability in soils used for livestock production
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), España, 2015)The spatial variability in soils used for livestock production (i.e. Natraquoll and Natraqualf) at farm and paddock scale is usually very high. Understanding this spatial variation within a field is the first step for ... -

(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2016)Se estudió el efecto del uso de la atmósfera controlada (AC), 1-metilciclopropeno (1-MCP) y su combinación, sobre la maduración del kiwi ‘Hayward’. Frutos cosechados con 16,6% de materia seca y 9% de sólidos solubles totales ... -
Uso del índice de verdor para determinar la dosis optima económica de nitrógeno en maíz
(Asociación Argentina de la Ciencia del Suelo, 2019-06)En regiones con excesos hídricos al comienzo de la estación de crecimiento, la aplicación de nitrógeno (N) en estadíos tempranos del maíz no es la mejor estrategia para maximizar la eficiencia de uso de dicho nutriente. ... -
Usos de la cianamida de hidrógeno y alternativos en kiwi (Actinidia sp.) y su potencial aplicación en Argentina
(Ediciones INTA, 2019-12)El kiwi (Actinidia sp.) es un frutal de hoja caduca que requiere acumular un determinado número de horas de frío menores a 7,2 ºC para lograr una óptima brotación, floración y contribuir a una adecuada fructificación. ... -
Utilization of fluorescence spectroscopy as a novel approach to evaluate the oxidative stability in beef retail displayed
(Elsevier, 2016-09)Beef samples from grazing steers finished with different seed-supplemented diets were vacuum packaged for 3, 14 and 56 days (VC) and subsequently exposed to aerobic conditions (AE) for 0 and 5 days. Different fluorescent ... -
Vaccination of pigs with the S48 strain of Toxoplasma gondii – safer meat for human consumption
(2015)As clinical toxoplasmosis is not considered a problem in pigs, the main reason to implement a control strategy against Toxoplasma gondii (T. gondii) in this species is to reduce the establishment of T. gondii tissue cysts ... -
Vaginal histological changes after using intravaginal sponges for oestrous synchronization in anoestrous ewes
(Wiley, 2015-04)To characterize the histological and cytological vaginal changes generated by the use of intravaginal sponge (IS) applied in oestrous synchronization treatments in ewes during mid‐non‐breeding season. Thirty‐five multiparous ... -
Vaginal mucus from ewes treated with progestogen sponges affects quality of ram spermatozoa
(2016)The use of intravaginal sponges (IS) to synchronize estrous onset in ewes provokes vaginitis, an increase in the vaginal bacterial load, and growth of bacterial species that are not present during spontaneous estrous ... -
Validation of a heat, moisture and gas concentration transfer model for soybean (Glycine max) grains stored in plastic bags (silo bags)
(2017-06)A two dimensional finite element model that predicts temperature distribution and moisture content of soybean stored in silo bags due to seasonal variation of climatic conditions is described. The model includes grain ... -
Variabilidad espacial de suelo a escala de lote y su relación con los rendimientos
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2016-03-23)El manejo sitio-específico dentro de un lote requiere delimitar zonas homogéneas.
