Three winter wheat growing seasons were compared in order to analyse crop development, CO2 fluxes and inter-annual variability in productivity. Crop development monitoring, leaf scale measurements and continuous eddy-covariance measurements were conducted in a production crop at the Lonzée experimental site in Belgium. The 3 years were characterised by similar soil proprieties (same site), similar management (sowing, harvesting, plant protection and nitrogen application, adhering to regional standards), and the use of recommended cultivars (the most productive ones for this region). The comparison of carbon fluxes, growth and productivity in the three growing seasons highlighted mechanisms affected by meteorological conditions and, in some cases, modulated by a cultivar effect. In particular, it was shown that (a) precociousness or lateness in stage development was triggered mainly by cumulated temperature during winter and early spring; (b) early development in one season could explain the larger ecosystem net carbon sequestration that year, but had no impact on grain yield; (c) low grain yield in one season was the result of a complex mechanism including drought in early spring, which hindered flag leaf development, and moist conditions in late spring, which restrained radiation and favoured the development of fungal diseases. In all cases, it was found that grain yield could not be related to gross primary productivity or net ecosystem exchange, suggesting that reallocation and translocation processes play a substantial role in grain filling.

Black-grass crossings were conducted outdoor for two successive years in a way to determine the percentage of resistant black-grass that can be engendered in one generation, after the introduction of one Target-Site resistant individual. After germination, plants were genotyped and couples of resistant and susceptible individuals were formed, then planted outdoor and enclosed with a pollen-proof cloth to avoid any external pollen contamination. Seeds were collected and tested in glasshouses with herbicide spraying. DNA analyses were also performed on surviving plants to distinguish hetero- from homozygotes. The resistance level of the progeny seems to be fairly high and Mendelean distribution is generally confirmed. The offspring of self-crossings was also observed to assess the facultative autogamy ability, according to the genotype and the presence of mutant ALS alleles (position W-574). [less ▲]

An experimental system combining an eddy covariance system, a micrometeorological station and soil chambers placed in planted areas and in root exclusion zones was installed during three successive years in a production crop managed in a traditional way at the Lonzée experimental site (Belgium). Measurements were made successively on seed potato, winter wheat and sugar beet. The general objectives of the study were, first to evaluate the relative contributions to total ecosystem respiration (TER) of heterotrophic, above ground autotrophic and below ground autotrophic respiration over a succession of three agricultural crops (seed potato, winter wheat and sugar beet) cultivated on successive years at the same location and, secondly, to identify the driving variables of these contributions. Results showed that, during the observation periods, TER was dominated by autotrophic respiration (AR) (60–90%) and that AR was dominated by its above ground component (60–80%). HR was found to increase with temperature and to be independent of Gross Primary Production (GPP), whereas AR was driven by GPP and was mostly independent of temperature. The AR response to GPP was specific to the crop: not only AR intensity but also AR distribution between its above- (ARa) and below- (ARb) ground components were found to differ from one crop to another and, in the winter wheat, from one development stage to another. Generally, ARb contribution to AR was found larger when carbon allocation towards roots was more important. An uncertainty analysis was made and showed that the main sources of uncertainties on the estimates were the spatial variability for soil chamber measurements and uncertainties linked to the data gap filling method for eddy covariance measurements.

Target-site resistance heredity in black-grass was assessed by observing the percentage of resistant individuals engendered by crossings. After germination, plants were genotyped as homo- or heterozygote for the W574 mutation on the ALS gene, which induces herbicide resistance. Individuals were then transplanted outdoor and crossed between one another and with other individuals issued from a population known as susceptible. To avoid an external pollen contamination, plants were enclosed within pollen-proof clothing during flowering time. Allogamy rate was also tested, by isolating heads one by one. Seeds issued from these crossings were collected and tested in glasshouses. Their DNA was also analysed. [less ▲]

This paper presents the results of a one year preliminary study in which a real-time monitoring system was used to feed the STICS soil crop model. The monitoring system was made of a self-organising wireless network within which microsensors collected and stored microclimatic and environmental data. As indicated by the statistical criteria (RMSE, normalized deviation and model efficiency), the optimisation of some wheat crop parameters allows the STICS model to predict the yields with good accuracy for three different soil types and seven different nitrogen application rates.
