Cover crop species can increase or decrease the fertilizer-nitrogen requirement in maize
(American Society of Agronomy; Estados Unidos, 2021-07-03)Cover crop species and termination date could affect fertilizer-N management and N diagnostic methods traditionally used in bare fallow-maize (Zea mays L.) systems. Our objectives were to (a) assess the impact of cover ... -
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 ... -
Dinámica del crecimiento de una pastura de agropiro alargado de acuerdo con la época de fertilización nitrogenada
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2013-08)Las pasturas de agropiro alargado Thinopyrum ponticum (Bark. y Dewey) en la Pampa Deprimida bonaerense, en términos generales, son considerados cultivos con pobre producción de forraje, de escaso valor nutricional para la ... -
Does nitrogen fertilization rate, timing and splitting affect sunflower yield and grain quality?
(Wiley, 2023-02)Nitrogen (N) deficiency could have a negative effect on sunflower (Helianthus annuus L.) yield and grain quality. Therefore, it is necessary to adjust the optimum rate, timing, and frequency of N fertilization to improve ... -
Economic optimum nitrogen rate analysis for feed and malting barley
(Wiley, 2022-07-10)The malt industry has specific requirements for malting barley (Hordeum vulgare L.) grain protein concentration (from 9.5 to 13%) and size (>85%), which could be affected by nitrogen (N) fertilization. We aimed to (a) ... -
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 the intensification of cropping sequences on soil organic carbon and its stratification ratio in contrasting environments
(Elsevier, 2021-01-19)In environments where continuous agriculture leads to soil organic carbon (SOC) depletion, intensification practices (i.e. polyculture, cover crops (CC), and crop fertilization) have been suggested as strategies to improve ... -
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 ... -
Indigenous mycorrhizal fungi from Argentina increase Zn nutrition of maize modulated by Zn fertilization
(Soil Science Society of Pakistan, 2014-06)The effect of nitrogen (N), phosphorous (P), sulfur (S) and zinc (Zn) fertilization on arbuscular mycorrhizal colonization (AMC), nutrition and growth of maize under contrasting tillage management was assessed in a field ... -
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 ... -
Nitrato en pecíolo e índice verde en estratos del canopeo del cultivo de papa
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-08)La concentración de nitrato en los pecíolos (NBS) y el Índice Verde (IV) medidos en las hojas inferiores del canopeo de papa podrían usarse como alternativa de los métodos tradicionales de evaluación del estado nutricional ... -
Nitrogen balance for potato crops in the southeast pampas region, Argentina
(Springer, 2013-01)The aim of this work was to build an N mass balance for the potato crop under irrigation conditions in the southeast pampas (Argentina) as a function of N rate and gravitational water. The experiment was developed in a ... -
Nitrogen Recovery Efficiency from Urea Treated with NSN Co-Polymer Applied to No-Till Corn
(MDPI, 2018-08-19)Nitrogen (N) rate increases used by many farmers produce a reduced or null effect on N recovery efficiency (RE) by crops. Therefore, management practices to reduce N losses and increase RE are necessary. Co-polymer maleic ... -
Prognosis and diagnosis of sulfur status in maize by plant analysis
(Elsevier, 2019-05)The analysis of sulfur concentration (SC) and nitrogen to S ratio (N/S) in plant tissue are some of the suggested tools to evaluate S deficiency in maize (Zea mays L.). However, the convenience of one over the other and ... -
Revisiting the relationship between nitrogen nutrition index and yield across major species
(Elsevier, 2024-03)Crop nitrogen (N) fertilization diagnoses via the N nutrition index (NNI)-yield relationship have been tested for several crop species, but a cross-species comparison of that relationship has not been performed yet. This ... -
Soil organic carbon in cropping sequences with predominance of soya bean in the argentinean humid Pampas
(Wiley, 2020-01)Soya bean (Glycine max (L.) Merr.) monoculture can lead to a decrease in labile fractions of soil organic carbon (SOC). This study sought to evaluate the effects of cover crops (CC), application of fertilizer, and crop ... -
Use of a critical phosphorus dilution curve to improve potato crop nutritional management
