A Comparison of indexes to estimate corn S uptake and S mineralization in the field
(2018-04)The development of simple predictors of sulfur (S) mineralization and its correlation with field-derived data may help improving corn S availability diagnosis. The objectives of this study were (1) to compare methods to ... -
Cold sweetening diversity in Andean potato germplasm from Argentina
(Wiley Online Library, 2018-04-02)BACKGROUND: Cold induced sweetening (CIS) is the accumulation of sucrose and reducing sugars in potato tubers at low temperatures. This process is central for the potato processing industry. During potato chip and French ... -

Effects of photoperiod sensitivity genes Ppd‐B1 and Ppd‐D1 on spike fertility and related traits in bread wheat
(Wiley Online Library, 2018-04-27)Increasing grain yield is a key breeding goal in bread wheat. Several authors have suggested that a spike fertility index (SF), that is the quotient between grain number per unit spike (GNS) and spikechaff dry weight (SCDW), ... -
Indicaciones Geográficas en Argentina: aportes metodológicos para el estudio de sus potencialidades y limitantes
(Instituto de Estudios Avanzados (IDEA), Universidad de Santiago de Chile, 2018-05)The Geographical Indications (GI) are signs of territorial quality that may contribute to producers organization, the introduction of innovations and the valuing of differential quality. In this sense, the GIs are regarded ... -
Development of the enhanced halsey model to predict equilibrium moisture content (EMC) of sunflower seeds with different oil contents
(American Society of Agricultural and Biological Engineers, 2018-05)Using the right equilibrium moisture content (EMC) relationship is critical for implementing successful aeration strategies and for determining the safe storage moisture content of grains and oilseeds. The oil content of ... -
