Assessing the mechanisms underlying sunflower grain weight and oil content responses to temperature during grain filling
Angeloni, Patricia; Aguirrezabal, Luis; Echarte, María Mercedes (Elsevier, 2021-03)Temperature and solar radiation during grain filling are the main drivers of grain weight and composition in several crops. While significant progress has been done on the effect of solar radiation intercepted by the plants ... -
Contribution of incident solar radiation on leaves and pods to soybeanseed weight and composition
Bianculli, Mariana Lujan; Aguirrezábal, Luis Adolfo Nazareno; Pereyra Irujo, Gustavo Adrian; Echarte, María Mercedes (2017-07)The weight and composition of soybean seeds (Glycine Max L. Merrill) depend on changes in carbonand nitrogen assimilate supply during grain filling. Soybean pods and seeds are green, evidencing theircapacity to capture ... -
Eco-physiological processes underlying maize water use efficiency response to plant density under contrasting water regimes
Hernandez, Mariano Daniel; Alfonso, Carla Susana; Cerrudo, Aníbal Alejandro; Cambareri, Matias; Della Maggiora, Aida; Barbieri, Pablo; Echarte, María Mercedes; Echarte, Laura (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 ... -
Influence of management practices on water-related grain yield determinants
Echarte, Laura; Alfonso, Carla; Gonzalez, Víctor Hugo; Hernández, Mariano; Lewczuk, Nuria; Nagore, María Luján; Echarte, María Mercedes (Oxford University Press, 2023-07-25)Adequate management of N supply, plant density, row spacing, and/or soil cover has proved useful to increase grain yields and/or grain yield stability across years of rainfed crops. We reviewed the impact of these management ... -
Maize transpiration efficiency increases with N supply or higher plant densities
Hernandez, Mariano Daniel; Alfonso, Cecilia; Echarte, María Mercedes; Cerrudo, Aníbal Alejandro; Echarte, Laura (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 ... -
Las multifacéticas remolachas: una reevaluación de sus posibilidades productivas a la luz de los conocimientos actuales
Rattin, Jorge Edgardo; Echarte, María Mercedes; Barrera, L.; Tognetti, Jorge; Di Benedetto, Adalberto (Ediciones INTA, 2022-04)La especie Beta vulgaris subsp. vulgaris comprende a las comúnmente llamadas remolachas, de las que existen tres tipos: hortícola, azucarera y forrajera. Aunque el principal órgano de interés es en todos los casos la raíz ... -
Un proyecto inspirador en el marco de la economía circular para el desarrollo territorial rural
Echarte, María Mercedes; Ischia, Claudia María (Estación Experimental Agropecuaria Balcarce, INTA, 2022-09)En el marco de un proyecto interdisciplinario e interinstitucional, la localidad rural de Los Pinos tiene una Unidad Demostrativa de Biogás que apuesta al desarrollo rural de la mano de la transformación de biomasa en energía. -
Soil respiration response to reductions in maize plant density and increased row spacing (Southeast pampas, Argentina)
Lewczuk, Nuria; Picone, Liliana; Echarte, María Mercedes; Alfonso, Cecilia; Rizzalli, Roberto Héctor; Echarte, Laura (Elsevier, 2024-09)Previous studies have recognized the influence of crop cover and agricultural management on variables (soil temperature, soil moisture, and root biomass) that influence soil respiration. However, despite the influence of ... -
Sorghum biomass yield and allocation as affected by the combination of photoperiod sensitivity, sweet-stalk and brown midrib traits
Erbetta, Elisa; Echarte, Laura; Sanz Smachetti, María Eugenia; Gabbanelli, Nadia; Echarte, María Mercedes (Elsevier, 2024-01)Context or problem: Traits like photoperiod sensitivity, sweet-stalk and brown midrib (bmr) have been introgressed to increase the biomass yield and quality of sorghum (Sorghum bicolor (L.) Moench) towards bioenergy yield ... -
Stover biogas potential of corn crops grown under contrasting water availability and nitrogen supply
Erbetta, Elisa; Echarte, Laura; Rodríguez Elizagaray, Consuelo; Depetris, Gustavo; Gabbanelli, Nadia; Echarte, María Mercedes (Elsevier, 2020-12-31)Corn stover is a biogas feedstock capable of enhancing agriculture bioenergy potential. Although the influence of growing conditions on biogas yield of corn stover has been reported, the joint effects of water and nitrogen ... -
Towards an ideotype for food-fuel dual-purpose wheat in Argentina with focus on biogas production
Gabbanelli, Nadia; Erbetta, Elisa; Sanz Smachetti, María Eugenia; Lorenzo, Maximo; Talia, Paola Mónica; Ramirez, Ignacio; Vera, Magdalena; Durruty, Ignacio; Pontaroli, Ana Clara; Echarte, María Mercedes (BioMed Central, 2021-04-05)Wheat straw, one of the most abundant agricultural residues worldwide, can be used to produce biogas, which is considered one of the most efficiently produced renewable energies. Wheat grown with the dual-purpose of producing ... -
