Morpho-physiological responses of tall wheatgrass populations to different levels of water stress
(Plos One, 2018-12)Tall wheatgrass [Elymus elongatus subsp. ponticus (Podp.) Melderis] is a perennial forage grass cultivated in dry, saline or alkaline environments. The morpho-physiological characteristics of four populations of tall ... -
Morpho‐physiological, biochemical and isotopic response of tall wheatgrass populations to salt stress
(Wiley, 2020-12)Tall wheatgrass [Elymus elongatus subsp. ponticus (Podp.) Melderis] is a C3 grass native from dry or saline habitats in SE Europe. The aim of this study was to better understand response mechanisms of populations from ... -
Persistencia de los efectos de la descompactación del suelo con paratill
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2020-07)En la Argentina predomina como sistema productivo la siembra directa donde la ausencia de remoción y el tránsito de máquinas cada vez más pesadas han incrementado los problemas de compactación. Para revertir este fenómeno ... -
Phosphorus fertilization of a grass-legume mixture: effect on plant growth, nutrients acquisition and symbiotic associations with soil microorganisms
(2015-09)Adding P on Lotus tenuis and Festuca arundinacea, pure or mixed, on growth, nitrogen (N) and phosphorus (P) acquisition and associations with soil microorganisms was studied to investigate the establishment of Lotus for ... -
Producción de biomasa, cobertura y calidad forrajera de Chloris gayana y Panicum coloratum en un suelo alcalino sódico de la Depresión del Salado
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2017-12)La expansión agrícola, que viene ocurriendo en la región durante las últimas dos décadas, no solo redujo considerablemente la superficie ganadera, sino que la desplazó hacia zonas marginales. En este contexto, la incorporación ... -
Promotion of Lotus tenuis and calf early weaning as a good management practice for breeding herds in marginal soils of the Flooding Pampa (Argentina)
(Ediciones INTA, 2020-08)The promotion of forage legumes in marginal environments for agriculture constitutes a major technological challenge for livestock farming. The legume Lotus tenuis (Waldst. & Kit.) is a good example of beneficial naturalization ... -
Promotion of Lotus tenuis in the flooding Pampa (Argentina) increases the soil fungal diversity
(2018-06)Forage promotion is an increasingly used agricultural practice that requires herbicide application to remove competing plant species. This work examined the effect of the forage legume Lotus tenuis on the fungal community ... -
Pureza física y germinación de cariopses de Chloris gayana Kunth y Panicum coloratum L. cosechados de plantas cultivadas en un suelo alcalino-sódico
(2018-04)El objetivo del estudio fue evaluar la pureza física, el porcentaje de germinación (G), la velocidad de germinación (VG) de cariopses de Chloris gayana cv. Finecut (Cg) y Panicum coloratum cv. Klein Verde (Pc) recolectados ... -
Respuesta de hongos benéficos del suelo asociados a Lotus tenuis a la aplicación de glifosato
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2017-12)En los últimos años se está adoptando la práctica de promoción de Lotus tenuis a través de la aplicación de glifosato en pastizales de La Pampa Deprimida debido a su importante aporte en cantidad y calidad de forraje. Sin ... -
Short-term plant community response to grassland management intended to improve forage quality for the endangered Pampas deer
(Elsevier, 2019-08)The Pampas deer is a medium-sized neotropical cervid whose population has been affected by the advancement of the agricultural frontier, poaching and depredation by introduced species. As a consequence, the population of ... -
Soil water availability and water absorption by maize in sodic soils with high water table
(Elsevier, 2023-05)Context: Because of the increasing prices of commodities over the last decades, crops like maize (Zea mays L.) are being cultivated in lowland sodic soils with physical-chemical constraints, such as those having natric ... -
Temporal Variation of Soil Physical Quality under Conventional and No-Till Systems
(2018-04)Determination of soil physical quality (SPQ) is very important because it is related to many important soil processes. However, it is not clear which indicators should be considered in this evaluation, and information about ... -
Temporal variation of soil sorptivity under conventional and no-till systems determined by a simple laboratory method
(2017-05)Soil water sorptivity (S) is an important property that measures the soil capacity to take water rapidly under capillary forces. Usually S is not included in soil laboratory routine experiments because there is not a widely ... -
The degree of maternal nutrient restriction during late gestation influences the growth and endocrine profiles of offspring from beef cows
(CSIRO, 2021)Context: Cow–calf operations in Argentina are managed under extensive grazing condition and the quality of forages is often poor during the second half of gestation. The severity of nutrient restriction in bovine gestation, ... -
The Effects of Age at Weaning and Length of Lipid Supplementation on Growth, Metabolites, and Marbling of Young Steers
(MDPI, 2020-10)The objective of this study was to determine how weaning age, days on supplements, and lipid supplementation affected the growth and marbling deposition of steers. Steers from a single sire were early weaned (n = 24) at ... -
The influence of protein restriction during mid- to late gestation on beef offspring growth, carcass characteristic and meat quality
(Elsevier, 2019-07)The objective of this study was to determine whether crude protein intake during the last three months of gestation affects growth performance, carcass characteristics and meat quality of steer progeny. At 134 ± 14 d of ... -
