Genetic improvement of peanut in Argentina between 1948 and 2004: links between phenology and grain yield determinants por Haro Juarez, Ricardo Javier, Baldessari, Jorge Javier, Otegui, Maria Elena

“…However, there is no information on (i) the partitioning of thermal time(TT) requirements between vegetative and reproductive phases, as well as between reproductive sub-phases representative of the seed set and seed-filling periods, and (ii) the effect of developmental changeson growth traits. Field experiments were performed to compute TT, grain yield determinants (i.e., seednumber and seed weight), and other related physiological traits. …”

The natural pest control potential of different landscapes por Peitz, Charlotte

“…While the relationship between these landscape structures and specific insects is relatively well explored, up-scaling these findings from field experiments to larger areas is difficult. This thesis aims to contribute to a better understanding of this issue by mapping the natural pest control potential of three agricultural landscapes in Sweden, based on the presence of specific landscape factors. …”

Nitrogen–sulfur fertilisation effects on gluten composition and industrial quality in Argentinean bread wheat cultivars differing in apparent sulfur recovery por Arata, Agustin Francisco, Rogers, Willian, Tranquilli, Gabriela, Arrigoni, Adriana C., Rondanini, Deborah Paola

“…The aim of this work was to analyse the responses of grain quality to N and S fertilisation and relate them to the relative quantitative composition of different subunits of gliadins and glutenins in 24 Argentinean bread wheat cultivars differing in apparent S recovery (ASR), cycle length and protein pattern. Two field experiments were conducted in the Humid Pampas of Argentina. …”

“…The study aimed to assess the inclusion of winter crops (WC) with different amounts of residues and different C:N ratios on the following: (i) the response to N fertilisation in the following late-maize (Zea mays L.), and to carry that comparison into a subsequent wheat crop (Triticum aestivum L.), and (ii) identify soil N indicators associated with these responses. Two field experiments (E1 and E2) were conducted in the Argentinean Pampas during two growing seasons to evaluate a WC/late-maize-wheat sequence under no-tillage. …”
