Areas homogéneas de producción agrícola en la provincia de Buenos Aires, Argentina
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 1996)Al considerarse los registros históricos de rendimientos de granos de girasol, maíz, trigo y soja, durante el período 1970-1993, se delimitaron 22 áreas homogéneas de producción agrícola en la provincia de Buenos Aires. ... -
Áreas homogéneas de producción agrícola en el este de la provincia de La Pampa
(Facultad de Agronomía, Universidad Nacional de La Pampa, 1999)El objetivo de este trabajo fue delimitar áreas con comportamientos homogéneos en la producción agrícola del este de la provincia de La Pampa (Argentina). Para ello se aplicaron técnicas de análisis multivariado (análisis ... -
Effect of slow-release urea inclusion in diets containing modified corn distillers grains on total tract digestibility and ruminal fermentation in feedlot cattle
(American Society of Animal Science, 2015-08)Ruminal degradable intake protein (DIP) deficit may result when cattle are fed diets containing a greater inclusion of processed corn grain and small to moderate inclusion of corn distillers grains (DG). This deficit may ... -
Effect of urea inclusion in diets containing corn dried distillers grains on feedlot cattle performance, carcass characteristics, ruminal fermentation, total tract digestibility, and purine derivatives-to-creatinine index
(American Society of Animal Science, 2015-01)Increased availability of rapidly fermentable carbohydrates and a great proportion of corn-derived CP in the diet may result in a degradable intake protein (DIP) deficit. Therefore, ruminal DIP deficit may result from high ... -
Impacts of vegetative and reproductive plasticity associated with tillering in maize crops in low-yielding environments: a physiological framework
(Elsevier, 2021-05)Selection for maize (Zea mays L.) grain yield in high-yielding environments at high population densities has favored a compact phenotype tolerant to crowding stress, bearing a single, well-grained ear. However, by contributing ... -
Leaf protein allocation across the canopy and during senescence in earlier and later senescing maize hybrids, and implications for the use of chlorophyll as a proxy of leaf N
(Springer, 2019-09)Leaf chlorophyll (chl) and protein distribution were analyzed throughout grain filling in four modern maize hybrids with contrasting senescence behavior, at three different canopy levels and at low-N (LN, 18 kg N ha−1) and ...
