Analysis of sink/source relations in bread wheat recombinant inbred lines and commercial cultivars under a high yield potential environment
(2018-02)Grain yield in wheat is generally considered to be sink-limited during grain filling. But is this limitation inherent to the crop species or a consequence of the breeding process? A way to ascertain this is by using genetic ... -
Evaluation of the agricultural production systems simulator simulating Lucerne and annual ryegrass dry matter yield in the Argentine Pampas and south-eastern Australia
(2016)Modelling plant growth provides a tool for evaluating interactions between environment and management of forage crops for pasture-based livestock systems. Consequently, biophysical and farm systems models are becoming ... -
Improving Yield and Quality of Processing Potato Crops Grown in the Argentinian Pampas: the Role of N, P and S and Their Impact on CO2 Emissions
(Springer Netherlands, 2018-03-17)The area grown with processing potato crops in the Argentinian Pampas has been increasing steadily since 1995. The aim of this work was to assess the effects of N, P and S upon yield and tuber quality and their impact on ... -
Inclusion of cover crops in cropping sequences with soybean predominance in the southeast of the Humid Argentine Pampa
(2013)The incorporation of a cover crop (CC) may be an alternative to increase soil carbon (C) and nitrogen (N) supply in crop sequences with a high frequency of soybean. The aims of this study were (i) to determine shoot biomass ... -
Incorporación de cultivos de cobertura previos a soja en el sudeste bonaerense
(2013-06)En la zona del sudeste bonaerense existe escasa información sobre las eventuales ventajas de la incorporación de los CC en los planteos productivos actuales, la cual sería de suma utilidad para evaluar la factibilidad de ... -
Kernel number response to plant density in tropical, temperate, and tropical × temperate maize hybrids
(Crop Science Society of America, 2020-02-07)Kernel set response to plant density was examined in terms of physiological processes underlying kernel set in temperate (Te), tropical (Tr), and temperate × tropical (TeTr) maize (Zea mays L.) hybrids. Four field experiments ... -
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 ... -
Métodos de colocación de fósforo en trigo y maíz bajo siembra directa en el sudeste bonaerense
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2018-12)La siembra directa (SD) produce cambios físicos, químicos y biológicos en el suelo que pueden afectar la disponibilidad de P para los cultivos. El uso eficiente de fertilizantes debe combinar factores como dosis, momento, ... -
Mid-Season High-Resolution Satellite Imagery for Forecasting Site-Specific Corn Yield
(MDPI, 2016-10)A timely and accurate crop yield forecast is crucial to make better decisions on crop management, marketing, and storage by assessing ahead and implementing based on expected crop performance. The objective of this study ... -
Potential for crop production increase in Argentina through closure of existing yield gaps
(Elsevier, 2015-12)Favorable climate and soils for rainfed crop production, together with a relatively low population density, results in 70–90% of Argentina grain production being exported. No assessment to date has tried to estimate the ... -
Predicting maize phenology: intercomparison of functions for developmental response to temperature
(American Society of Agronomy, 2014-12)Accurate prediction of phenological development in maize (Zea mays L.) is fundamental to determining crop adaptation and yield potential. A number of thermal functions are used in crop models, but their relative precision ... -
Producción potencial de semillas por planta en especies de Bromus (Sección Ceratochloa), en el sudeste de la provincia de Buenos Aires = Potential seed production per plant in species of Bromus (Section Ceratochloa) at southeast of Buenos Aires province
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2016)En Argentina crecen varias especies de la Sección Ceratochloa del género Bromus, que se destacan por su producción de forraje inverno-primaveral. El valor de estos recursos nativos ha incentivado la colecta de semillas de ... -
Reproductive development of Lotus tenuis (fabaceae) crop defoliated at different times and intensities
(Scientific Research Publishing, 2016)Lotus tenuis forage yield has been quantified under defoliation conditions in pastures, grasslands and under dual-purpose production of both livestock forage and seeds. However, little is known about the effects of defoliation ... -
Selection for high spike fertility index increases genetic progress in grain yield and stability in bread wheat
(Springer Netherlands, 2018-07-18)Spike fertility index (SF) has been proposed as a promising trait to be used as a selection criterion in wheat breeding programs aimed at increasing grain yield, but no actual evidence of its successful application has ... -
Variabilidad espacial de suelo a escala de lote y su relación con los rendimientos
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2016-03-23)El manejo sitio-específico dentro de un lote requiere delimitar zonas homogéneas. Múltiples variables, tales como algunas propiedades del suelo, son usadas para la zonificación. El análisis de “cluster fuzzy k-means” (CFK) ... -
Yield potential and yield stability of Argentine maize hybrids over 45 years of breeding
(Elsevier, 2016-10)Maize (Zea Mays L.) grain yield have increased during the last decades and there is an ample range of rates of grain yield increments reported in the literature. Maize hybrids comparison at their optimum plant density might ...
