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 ... -
Analysis of storage conditions of a wheat silo-bag for different weather conditions by computer simulation
(Elsevier, 2013-12)A validated mathematical model was used to analyse grain storage condition and determine the change in concentration of CO2 in a silo-bag holding wheat from summer to winter for a typical productive region with sub-tropical ... -
Delineation of management zones to improve nitrogen management of wheat
(2015-01)Site-specific management of N (NSSM) is an attractive and intuitive approach to increasing N fertilizer use efficiency (NUE) of agricultural systems by adjusting fertilizer rates to the soil characteristics. The objective ... -
Denitrification in a Soil under Wheat Crop in the Humid Pampas of Argentina
(Scientific Research, 2014-09)The need to accurately estimate gaseous nitrogen losses from soils is required to have a better understanding of the processes involved as well as soil and environmental conditions, and management practices contributing ... -
Efecto de la fertilización nitrogenada en soja intersembrada en trigo en Balcarce
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-04)Es sabido que la soja intersembrada en trigo tiene bajo crecimiento inicial, lo cual podría afectar negativamente la formación de nódulos fijadores de nitrógeno (N) y limitar el crecimiento de la soja luego de la cosecha ... -
Effect of hydrocolloids on the properties of wheat/potato starch mixtures
(Wiley, 2016-07)The physicochemical, pasting, thermal, viscoelastic, and syneresis properties of nine formulations prepared with wheat starch, potato starch, and hydrocolloids (pectin, HPMC, arabic gum, and konjac glucomannan (KG)) were ... -
Evaluating the impacts and benefits of sheldgeese on crop yields in the Pampas region of Argentina: a contribution for mitigating the conflicts with agriculture
(Elsevier, 2019-07-01)Conflicts between waterfowl and agriculture are common in many nations around the world. However, these birds can also provide a variety of benefits that humanity can obtain from nature. There are three migratory and endemic ... -
Field methods for making productivity classes for site-specific management of wheat
(Springer, 2022-02-02)Reducing the decision-making unit to classes within fields can improve yields, efficiency in the use of nutrients and profitability of crops. The objectives were to compare methods for class delimitation in wheat (Triticum ... -
Frost damage on grain number in wheat at different spike developmental stages and its modeling
(Elsevier, 2019-02)Frosts may damage wheat (Triticum aestivum L.) spikes and severely reduce their yield. The objective of this study was (i) to quantify the level of susceptibility to frost at different spike developmental stages, and (ii) ... -
Labranza y fertilización como moduladores de la dinámica de comunidades microbianas asociadas a un cultivo de trigo en el sudeste bonaerense (Argentina)
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2017)El objetivo del trabajo fue evaluar a campo el efecto de la labranza y la fertilización con macro y micronutrientes, sobre el crecimiento y la colonización de raíces por hongos micorrícicos arbusculares y la abundancia de ... -
Low temperature differentially affects tillering in spring and winter wheat in association with changes in plant carbon status
(Wiley, 2015-03)The higher tillering potential of winter wheat cultivars as compared to spring ones has been attributed to an earlier tillering onset in the former. Tillering in grasses is known to depend on temperature and light environment, ... -
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, ... -
¿El Nan mejora el diagnóstico de nitrógeno en trigo?
(2013-06)El aporte de nitrógeno (N) por mineralización es una de las principales fuentes de N para los cultivos, particularmente en suelos con altos contenidos de materia orgánica (MO) (Echeverría y Ferrari, 1993). En general, el ... -
Phosphorus placement effects on phosphorous recovery efficiency and grain yield of wheat under no-tillage in the Humid Pampas of Argentina
(2014)No-till (NT) affects dynamics of phosphorus (P) applied. Wheat response to P fertilization can be affected by available soil P, grain yield, placement, rate, and timing of fertilization. Furthermore, mycorrhizal associations ... -
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 ... -
Soybean and wheat response to lime in no-till Argentinean mollisols
(Elsevier, 2015-09)Crop production in Argentina has significantly increased over the past few years; this increase was consequence of better management practices which included P and N fertilization and, occasionally, S fertilization. Commonly ... -
Sulfur affects root growth and improves nitrogen recovery and internal efficiency in wheat
(2017)Wheat plants were cultivated in pots with the objective of evaluate the effect of two sulfurrates (+S and -S) on i) shoot growth, S and nitrogen uptake and nitrogen use efficiency(NUE) and ii) root growth and architecture ... -
Sulfur Mineralization: A Key Process for Diagnosing Its Deficiency in Wheat
