A modification of the arcsine–log calibration curve for analysing soil test value–relative yield relationships
(2017-03)This article aims to discuss the arcsine–log calibration curve (ALCC) method designed for the Better Fertiliser Decisions for Cropping Systems (BFDC) to calibrate relationships between relative yield (RY) and soil test ... -
Assessing the impact of high-input management for reducing soybean yield gaps on high-productivity farms
(Elsevier, 2022-03)To increase soybean actual yields (Ya), modern farmers are interested in exploring novel intensification options. We hypothesize that the inclusion of a high-input treatment in high-productivity systems may potentially ... -
Comportamiento de inoculantes para soja en la zona sur de la provincia de Santa Fe, Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2007)La soja fija el nitrógeno atmosférico en simbiosis mutualista con Bradyrhizobium japonicum y/o Sinorhizobium, mediante la Fijación Biológica del Nitrógeno (FBN). El uso de especies capaces de nodular vigorosamente y de ... -
Efectos de cultivos de cobertura sobre el agua del suelo, el aporte de carbono al sistema y el rendimiento de soja en diferentes ambientes
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2022-02)La sustentabilidad de los ambientes agrícolas en la región pampeana húmeda argentina es afectada por el monocultivo de soja (Glycine max (L.) Merr.). La baja eficiencia en el uso de los recursos del ambiente durante los ... -
Intensive Soybean Management : an Integrated Systems Approach
(2017)Ecological intensification impacted soybean yield, biomass and N uptake. Narrow row spacing, high seeding rate, other best production practices, and balanced nutrition increased partitioning effi ciency for biomass, measured ... -
Maize nitrogen management in soils with influencing water tables within optimum depth
(Wiley, 2020-10)The central temperate Argentinean region is currently affected by rising water tables, allowing higher and more stable maize yields (Zea mays L) when they fluctuate within optimum depth. However, limited information was ... -
Masas de aire y patrones de circulación asociados a la ocurrencia de deficiencias hídricas severas durante el período crítico de maíz
(Ediciones INTA, 2020-12)En estudios referentes a fenómenos meteorológicos asociados a una región, la Climatología Sinóptica permite analizar las interacciones existentes entre la circulación atmosférica y las condiciones presentes en superficie. ... -
N:P:S stoichiometry in grains and physiological attributes associated with grain yield in maize as affected by phosphorus and sulfur nutrition
(2017-03)Balanced nutrition is necessary to reduce yield gaps in maize. Simultaneous phosphorus (P) and sulfur (S) deficiencies may be present in soils, so a P × S interaction is expected. In maize, yield is closely related to grain ... -
New insights into soybean biological nitrogen fixation
(American Society of Agronomy, 2018-08)Soybean biological N2 fixation (BNF) relationships with fertilizer N and yield response have been comprehensively reviewed in the scientific literature. However, the study of the N-gap between N uptake and N supplied by ... -
Nutrient partitioning and stoichiometry in soybean: A synthesis-analysis
(2017-01)On-farm attainable soybean yields are primarily limited by nutrient and water supply. High-yielding soybeans is related to high nutrient uptake. A proposed theoretical framework underpinning yield formation includes plant ... -
Plant stand, nodulation and seed yield in soybean as affected by phosphate fertilizer placement, source and application method
(2013-11)Establishing an optimum plant population at planting is the start-point for assuring seed yield in crops. In addition to plant establishment, the onset of a fully functional nodule system is crucial for nitrogen nutrition ... -
Relación estadística entre los rendimientos de maíz y la ocurrencia de deficiencias hídricas en el departamento Rosario
(Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2018)Las condiciones ambientales de temperatura, radiación y agua son factores determinantes en el crecimiento, desarrollo y en la producción final del cultivo. El agua disponible es generalmente el principal factor que limita ... -
Relative importance of biological nitrogen fixation and mineral uptake in high yielding soybean cultivars
(2017-09)Backgrounds and aims: Soybean yield depends on total N uptake, N use efficiency, and harvest index. Nitrogen uptake relays on biological fixation (BNF) and soil absorption. Usually, BNF is considered a yield-related process. ... -
Soja de alto rendimiento: ganancia genética y limitación por nitrógeno
(IPNI, 2017-12)La mejora genética del rendimiento de soja desde la década de 1980 hasta la del 2010 representó 30% promediando en sitios ubicados en los Estados Unidos y Argentina. Para todas las pocas de liberación, la fertilización ...
