Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date
(2016-02-01)It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ... -
Spatial and temporal variation in the migration of Ruddy-headed Goose in southern South America using satellite tagging
(Cambridge University Press, 2020-04-30)Ruddy-headed Goose Chloephaga rubidiceps is the smallest of the five South American sheldgeese and has two separate populations: one sedentary, which resides in the Malvinas/Falkland Islands and one migratory that overwinters ... -
Spatial–temporal trends and economic losses associated with bovine abortifacients in central Argentina
(Springer, 2022-07-30)The aims of this work are, firstly, to provide the geolocalization of cases of bovine abortion with definitive diagnosis and, secondly, to estimate the economic losses due to the most frequent abortifacients diagnosed ... -
Spike architecture traits associated with type II resistance to fusarium head blight in bread wheat
(Springer, 2021-11-05)Fusarium head blight (FHB) remains a devastating disease in bread wheat (Triticum aestivum L.). Genetic resistance to FHB is complex; aside from active physiological resistance, plant developmental and morphological traits ... -

(Universidade Federal de Lavras, 2019-12-13)Stand density management diagrams (SDMD) provide a guide for forest density management taking into account stands attributes such as trees´ diameter or volume. One of the most common species planted in Pampean plains of ... -
Standard methods for fungal brood disease research = Métodos estándar para la investigación de enfermedades fúngicas de la cría
(Taylor & Francis, 2013)Chalkbrood and stonebrood are two fungal diseases associated with honey bee brood. Chalkbrood, caused by Ascosphaera apis, is a common and widespread disease that can result in severe reduction of emerging worker bees and ... -
Storage of WDGS under hermetic and non-hermetic conditions : effect on sensory properties, microorganisms, mycotoxins and nutritional value.
(Elsevier, 2019-01)WDGS production in Argentina substantially increased in the last 5 years and become a frequent constituent for feed diets. However, due to the extremely high moisture content of the product, quality deterioration occurs ... -
Storing soybeans (Glycine max) in silo bags: economic outcomes and grain loss risk
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020-12-01)Silo bags have the potential to increase grain marketing efficiency and to give farmers additional bargaining power. However, silo bags are prone to tearing that can cause grain losses. This article assesses the economic ... -
