Operational planning of herbicide-based weed management
(2013-10)Weeds cause crop yield loss due to competition, interfere with agricultural activities and reduce grain quality due to seed contamination. Among the numerous methods for weed control, the use of herbicides is the most ... -
Modeling seed dormancy release and germination for predicting Avena fatua L. field emergence: A genetic algorithm approach
(2014-01-24)Avena fatua is a cosmopolite weed species which produces severe yield losses in small-grain production systems in temperate and semiarid climates. In the semiarid region of Argentina, A. fatua field emergence patterns show ... -
Feeding value of whole raw soya beans as a protein supplement for beef cattle consuming low‐quality forages
(2018-02)Experiments (Exp) I and II were conducted to compare raw whole soya beans (WSB), roasted (rWSB) or other protein sources as supplements of low‐quality forages fed ad libitum to beef cattle, upon DM intake (DMI), ruminal ... -
How leaf rust disease and its control with fungicides affect dough properties, gluten quality and loaf volume under different N rates in wheat
(2018-03)The unique viscoelastic properties of gluten make bread wheat (Triticum aestivum L.) a staple food. The specific balance between gluten fractions, together with grain protein content (GPC), defines nutritional and end-use ... -
Soil physical properties under different cattle stocking rates on Mollisols in the Buenos Aires Province, Argentina
(2018-09)This study evaluated the impact of different cattle stocking rates on different soil physical properties in different soils in an integrated livestock no-till agricultural system. We evaluated three stocking rates ... -
Efecto de los cultivos de cobertura otoño invernales, sobre el rendimiento y acumulación de N en maíz en el Sudoeste Bonaerense
(2014-12)La utilización de cultivos de cobertura (CC) tiene efecto sobre la acumulación de N y rendimiento de los cultivos sucesores. El objetivo de este trabajo fue evaluar la producción, los componentes del rendimiento y acumulación ... -
Changes in Weed Communities of Spring Wheat Crops of Buenos Aires Province of Argentina
(2014-03)During 2004 to 2008, weed surveys were conducted in 373 wheat fields of two different cropped areas (southwest [SW] and southeast [SE]) of the southern region of Buenos Aires Province of Argentina where different weed ... -
A new formulation of oxalic acid for Varroa destructor control applied in Apis mellifera colonies in the presence of brood
(2016-07)An organic product based on oxalic acid was evaluated for use in Varroa control under spring/summer climatic conditions in Argentina. The formulation consists of four strips made of cellulose impregnated with a solution ... -
A flexible and practical approach for real-time weed emergence prediction based on Artificial Neural Networks
(2018-06)Most popular emergence prediction models require species-specific population-based parameters to modulate thermal/hydrothermal accumulation. Such parameters are frequently unknown and difficult to estimate. Moreover, such ... -
El cultivo de trigo en la región semiárida bonaerense: impacto sobre algunas propiedades químicas del suelo
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2013-08)La intensificación de la agricultura en la región semiárida se caracterizó por una disminución del área destinada a pasturas, a favor de la superficie con monocultivo de trigo. En este contexto, la rotación de cultivos, ... -
Variabilidad espacial de la profundidad del suelo. Métodos de interpolación para el sudoeste bonaerense
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-12)La presencia de tosca es una de las principales limitantes de la producción agropecuaria del sudoeste bonaerense. La elaboración de mapas de profundidad de suelo resulta un paso previo a su manejo por ambientes. Se realizaron ...
