(2016-08)El cultivo de maíz, ocupa los primeros lugares en la producción mundial de granos, está sujeto al ataque de plagas de los granos almacenados, cuyas infestaciones se realizan tanto en cultivo en pie como en almacenamiento. ... -
Age at First Gestation in Beef Heifers Affects Fetal and Postnatal Growth, Glucose Metabolism and IGF1 Concentration
(MDPI, 2021-11)This study aimed to determine the effects of age at first gestation on offspring growth performance, glucose metabolism, and IGF1 concentration. Heifers impregnated by AI from a single bull at 15 months of age (15 M, n = ... -
¿Cuánto importa la frecuencia con la que monitoreamos el crecimiento y biomasa de las pasturas y verdeos?
(Ediciones INTA, 2020-11)Incrementar el consumo del forraje de alta calidad producido por las pasturas es una de las vías más eficientes para aumentar la productividad y la renta de las empresas ganaderas pastoriles. Este trabajo intenta cuantificar, ... -
Cultivos anuales y bianuales de frutilla en el Sudeste de la provincia de Buenos Aires: modificaciones en los parámetros de crecimiento.
(Universidad Nacional del Litoral, Facultad de Ciencias Agrarias, Esperanza, Santa Fé, Argentina., 2016)A nivel mundial se producen 800.0000 toneladas de frutilla (Fragaria ananassa Duch.) y en Argentina 50.000 t en aproximadamente 1.300 hectáreas. El comportamiento productivo de la frutilla varía entre el primer y segundo ... -
Curvas de crecimiento de forrajeras templadas irrigadas
(Asociación Latinoamericana de Producción Animal, 2001)Con el objetivo de construir y comparar las curvas de distribución estacional de forraje de 15 gramíneas y leguminosas se realizaron cuatro ensayos entre 1996 y 1999. Cada uno constó de dos repeticiones compuestas cada una ... -
Does the photo-thermal environment limit post-flowering maize growth?
(Elsevier, 2020-07-01)After canopy closure and in the absence of limitations by water or nutrient availability, crop growth rate (CGR) of maize (Zea mays L.) is ultimately constrained by the daily incident radiation and temperature of the ... -
Effect of different gamma radiation doses on the germination and seedling growth of wheat and triticale cultivars
(Southern Cross Publishing, 2018-12)Plant breeding of wheat and triticale in Argentina is based on the objective of improving an individual crop, with respect to resistance to drought stress. The use of gamma radiation holds promise for physiological crop ... -
Effect of Protein Restriction During Mid-to Late Gestation of Beef Cows on Female Offspring Fertility, Lactation Performance and Calves Development
(E-Cronicon, 2019-12)Cow calf operation in Argentina are managed under extensive grazing condition and the quality of forages is often poor during second half of gestation. Protein restriction in bovine gestation affects production traits in ... -
Effects on soybean growth and yield of wheat-soybean intercropping system
(Khalsa Publications, India, 2018)It has been demonstrated that soybean (Glycine max) produces lower yields at relay intercropping with wheat (Triticum aestivum) than if it is sown as a sole crop. However, most studies considered wider or irregular soybean ... -
Growth of the wild potato Solanum commersonii (Solanaceae) among grass tussocks under different defoliation intensities = Crecimiento de la papa silvestre Solanum commersonii (Solanaceae) entre matas de gramíneas bajo diferentes intensidades de defoliación
(Asociación Argentina de Ecología, 2018)Solanum commersonii is a wild potato, valuable as a socioeconomic resource for a breeding program of feeding crops. In grasslands, this species grows associated to Paspalum quadrifarium, a forage grass managed under ... -
Growth, nutrient uptake and symbiosis with rhizobia and arbuscular mycorrhizal fungi in Lotus tenuis plants fertilized with different phosphate sources and inoculated with the phosphate-solubilizing bacterium Pantoea eucalypti M91
(2014-12)Background and aims: The aim of this work was to evaluate the ability of P fertilization and phosphate-solubilizing bacteria (PSB) inoculation to promote the growth of L. tenuis in typical soils of the Salado River Basin ... -
Morpho-physiological response to vertically heterogeneous soil salinity of two glycophyte woody taxa, Salix matsudana x S. alba and Eucalyptus camaldulensis Dehnh
(Springer International, 2017-07)Aims Growth and physiology of Salix matsudana x S. alba and E. camaldulensis were evaluated in vertical saline gradients to test whether growth is determined by the mean salinity of rhizosphere, the average salinity weighed ... -
N and S concentration and stoichiometry in soybean during vegetative growth: Dynamics of indices for diagnosing the S status
(Elsevier, 2016-11)Information regarding the pattern of sulphur (S) accumulation in shoots is scarce for field crops and few comprehensive analysis were performed on N:S stoichiometry. Particularly, the need to study the patterns of uptake, ... -
