(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste (UNNE), 2022-12)Con el objetivo de asociar el tamaño de los ornamentos sexuales con caracteres reproductivos y productivos en gallinas del cruzamiento de tres vías Campero Casilda se calcularon, en 97 aves de 30 semanas, los índices de ... -
OSTRICH-CROPGRO multi-objective optimization methodology for calibration of the growing dynamics of a second-generation transgenic soybean tolerant to high temperatures and dry growing conditions
(Elsevier, 2023-02)Current estimates show that the impact of climate change on agriculture will result in yield losses in major crops of 8–43%, mainly due to a combination of drought and heat. Second-generation transgenic crops are expected ... -
Diallel analysis of kernel weight and grain-filling traits in maize grown under contrasting nitrogen supply
(Wiley, 2023-02)Understanding the inheritance of maize (Zea mays L.) kernel weight (KW) under contrasting nitrogen (N) supply is crucial for obtaining high KW across diverse N conditions. This work evaluated broad-sense heritability (H2), ... -
Overcoming seed dormancy of junglerice (Echinochloa colona)
(Universidad de Concepción (Chile), 2022-08)Junglerice (Echinochloa colona L. Link) seed dormancy can persist 8 months after harvest and, once overcome, seeds can germinate over a long period of time. Light or high temperatures could overcome seed dormancy, while ... -
Genetic gains in grain yield and related physiological attributes in Argentine maize hybrids
(Elsevier, 2006-02)Genetic gains in grain yield and related phenotypic attributes have been extensively documented in maize (Zea mays L.), but the effect of breeding on the physiological determinants of grain yield is yet poorly understood. ... -
Fracciones de fósforo edáfico bajo diferentes manejos = Phosphorus fractions under different managements
(Asociación Argentina de la Ciencia del Suelo, 2022-12)El fósforo (P) es uno de los nutrientes que más limita la producción agrícola. A nivel mundial, la región pampeana presenta los mayores déficits de P edáfico. Como su existencia en el suelo varía desde iones en solución a ... -
Physicochemical transformations of corn-based snacks with underexploited grains addition during storage: multi-analytical assessment
(Wiley, 2022-11)Corn-based snacks were prepared with the addition of 25% of millet, sorghum, quinoa, and canary seed flours, which are scarcely used grains for human food and can grow in low-fertility soils. GuggenheimAnderson-de Boer (GAB) ... -
Crossing strategy for breeding campero chickens. An inta-university collaborative project
(Sociedad Argentina de Genética, 2021-12)Campero chicken is a bird destined to production systems alternative to the industrial one. Campero INTA is a two-way cross between synthetic populations generated by INTA in Pergamino. These populations have remained ... -
Relación yema: albumen en huevos de tres genotipos de gallinas ponedoras destinadas a sistemas semi intensivos
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata, 2022-08-06)Se estudió el comportamiento dinámico de la relación yema:albumen en huevos del cruzamiento de tres vías Campero Casilda en comparación con Negra INTA y Rhode Island Red. Se trabajó con muestras aleatorias de 15 huevos de ... -
Variabilidad, tendencia y eventos extremos en los rendimientos agrícolas a nivel de partidos en la Provincia de Buenos Aires
(Facultad de Ciencias Económicas, Universidad de Buenos Aires, 2022-06-09)Climate variability is the main determinant of fluctuations in the productive and economic results of agriculture. Due to Climate Change, extreme events are expected to occur with greater frequency and intensity in the ... -
Fin de las reservas de fertilizantes fosfatados: ¿realidad o restricciones geopolíticas?
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2022-08-30)El fósforo (P) es un elemento fundamental para toda la vida en la tierra, y no presenta un sustituto en la producción de alimentos. El suministro de P desde las reservas de rocas fosfóricas está concentrado en unos pocos ... -
Efecto del secado y manejo agronómico sobre propiedades físicas asociadas a la dureza del grano en híbridos de maíz
(Universidad Tecnológica Nacional, Argentina, 2022-06-22)Se evaluó el efecto de distintos tratamientos de secado (natural, 50 y 70 °C) y manejo agronómico (sin y con re-fertilización en pre-floración) sobre la dureza endospérmica en cuatro híbridos de maíz (AW 190, NK 940, Cóndor ... -
Artificial selection for grain yield has increased net CO2 exchange of the ear leaf in maize crops
(Oxford University Press, 2021-03)Identifying the physiological traits indirectly selected during the search for high-yielding maize hybrids is useful for guiding further improvements. To investigate such traits, in this study we focused on the critical ... -
