An architectural analysis of the elongation of field-grown sunflower root systems. Elements for modelling the effects of temperature and intercepted radiation
(Society for Experimental Biology, 1996-03)The effects of photosynthetic photon flux density (PPFD) and soil temperature on root system elongation rate have been analysed by using an architectural framework. Root elongation rate was analysed by considering three ... -
Eco-physiological processes underlying maize water use efficiency response to plant density under contrasting water regimes
(Elsevier, 2020-09)This study quantified maize (Zea mays L.) water use efficiency for grain yield (WUEg) in response to plant density under contrasting water regimes; and focused on relevant eco-physiologial processes underlying the responses ... -
Grupos funcionales de plantas, producción de forraje y eficiencia de uso de radiación de pastizales naturales en condiciones potenciales y limitadas de agua y nitrógeno
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)Con el objetivo de analizar el efecto de la disponibilidad hídrica y nitrogenada sobre el crecimiento primavero estival de forraje, se condujo un experimento en un pastizal natural de la Pampa Deprimida (Argentina) con ... -
Maize grain yield components and source-sink relationship as affected by the delay in sowing date
(Elsevier, 2016-11)Delaying maize (Zea mays L.) sowing date can diminish grain yields through reductions in the number, size and activity of growing grains (sink strength) and/or reductions in the assimilate supply (source capacity) to grains ... -
Maize transpiration efficiency increases with N supply or higher plant densities
(Elsevier, 2021-03-08)Most of the studies addressing the influence of management practices on seasonal crop water use efficiency (i.e., the ratio between shoot biomass and evapotranspiration in a seasonal scale, WUE(B, ET, s)) have focused on ...
