TL;DR: A set of qualitative and quantitative questionnaires on perceived risks and foreseen impacts of climate and climate change on agriculture in Europe was distributed to agro-climatic and agronomy experts in 26 countries as mentioned in this paper.

TL;DR: Five additional avenues that agronomic research could follow to strengthen the ecological intensification of current farming systems are proposed, assuming that progress in plant sciences over the last two decades provides new insight of potential use to agronomists.

TL;DR: In this article, the authors compared the performance of eight widely used, easily accessible and well-documented crop growth simulation models (APES, CROPSYST, DAISY, DSSAT, FASSET, HERMES, STICS and WOFOST) for winter wheat (Triticum aestivum L.) during 49 growing seasons at eight sites in northwestern, Central and southeastern Europe.

TL;DR: In this paper, a large volume application of Biochar (30 and 60 t −1 ) on durum wheat in the Mediterranean climate condition, showing the viability of BC application for carbon sequestration on this crop.

TL;DR: Alfalfa is a potential forage resource for the improvement of hilly areas of Mediterranean environment and the combination of early and late harvest times would allow a better distribution of the forage production between the months of June and September as well as a fair useful forage regrowth during the weeks of October and November.

TL;DR: In this paper, the influence of tillage and mulch practices on economics, energy requirement, soil physical properties and performance of maize and wheat was investigated. But, the results revealed that mulch significantly affected the soil physical property and growth of maize.

TL;DR: In this paper, the performance of intercrops of pea (Pisum arvense L.), a popular legume used in intercropping systems with winter cereals for forage and silage production, with wheat (Triticum aestivum L.), rye (Secale cereale L.), and triticale (×-Triticosecale Wittmack) in two seeding ratios (60:40 and 80:20) were compared with monocrops of Pea and cereals, for two growing seasons.

TL;DR: In this paper, a crop simulation model, SALUS, was used to select optimal nitrogen fertilizer rates using strategic and tactical approaches in a spatially variable field where three distinct management zones had been previously identified.

TL;DR: Reduction in soil N min in vetch and bare fallow treatments was similar, showing that N losses can be reduced in this cropping system, either by replacebare fallow with barley or smaller N fertiliser application to maize.

TL;DR: The results suggest that allocating more N to PBA should increase cotton biomass, harvest index, and yield.

TL;DR: In this article, the authors present the crop rotation model CropRota, which integrates agronomic criteria and observed land use data to generate typical crop rotations for farms and regions.

TL;DR: The authors used the WOFOST crop growth simulation model to examine crop yield responses to a set of plausible scenarios of climate change for Finland up to 2100, including some that exceed 4°C global mean temperature increase relative to pre-industrial.

TL;DR: In this paper, the main factors affecting yield variability and the farmer management strategies used to sustain crop productivity while reducing input use were identified and categorised using classification and regression trees to describe management strategies under conventional and organic systems and to identify and categorise the main variables associated with rice yield variability.

TL;DR: The results of this study show that it is indeed possible to both detect CWM and discriminate between groups of hybrids using non-destructive high throughput phenotyping, and that this technology presents a potentially useful application for breeding in the future.

TL;DR: In this paper, the effects of nitrogen availability related to fertilizer type, catch crop management, and rotation composition on cereal yield and grain N were investigated in four organic and one conventional cropping systems in Denmark using the FASSET model.

TL;DR: Analysis of leaf and storage root growth of sugar beet plants sown in autumn or very early in spring with regard to possible yield increases forms a basis to predict yield with models for bolting resistant sugar beet varieties.

TL;DR: In this article, the authors used Expert-N to investigate the ability of four generic-mechanistic crop models that were originally developed under field conditions to simulate the plant growth of spring wheat grown in open-top chambers (OTC) under different environmental conditions.

TL;DR: In this paper, an integrated agronomic, environmental and economic assessment of arable and dairy farming using indicators was conducted, based on periodic interviews over a 3-year period in seven representative farms.

TL;DR: It was shown that CTTP could be replaced with NTDS to maintain yield and save labor for super hybrid rice production in rice–oilseed rape cropping system.

TL;DR: In this paper, a methodological approach for the definition of the most reliable index is proposed and the adopted procedure allows to define the NIR/R560, even with some degrees of incertitude, as the most suitable index for the evaluation of tomato crop nutritional status.

TL;DR: In this paper, a decision support system, called dosavina, is developed as a tool to calculate the optimal volume rate for spray applications in vineyards. But the system is not suitable for large plantations.

TL;DR: The results suggest that future breeding of B. napus should be based on old cultivars, since more modern varieties seem to have lower potentials to respond to CO 2 and thus counteract the detrimental effects of yield reducing environmental factors such as temperature and O 3.

TL;DR: Soil salinity levels equal to or higher than 6.5 dS m −1 affected the plants by reducing the grain number but not the straw weight, confirming an interaction between the salinity and drought effects on faba bean productivity.

TL;DR: In this article, the authors investigated the farm economic net return of three conservation tillage practices (NIT - Non-Inversion Tillage, MT - Minimum Tillage and NT - No-Tillage) performed at variable intensity within predefined management zones.

TL;DR: SPACSYS, a model of C and N cycling in the soil–plant–atmosphere continuum that incorporates a detailed three-dimensional root growth sub-model, was tested for its ability to predict the growth and root length density (RLD) distribution of winter wheat.

TL;DR: Compared physiological responses of fully irrigated seedling and regrowth lucerne crops grown under similar environmental field conditions can be used as guidelines to develop differential management strategies and improve the parameterization ofLucerne simulation models.

TL;DR: Differences in grain quality parameters were maintained through years, indicating that these traits are under strong genetic control and significantly affected grain yield and N and S content of grain, but did not affect quality parameters.

TL;DR: In this article, direct drilling into zero tilled (ZT) soil of two spring barley ( Hordeum vulgare L.) cultivars (six-rowed Rolfi and tworowed Saana), spring oats ( Avena sativa L., cultivar Roope), and spring wheat ( Triticum aestivum L, cultivar Kruunu) was compared with conventional tillage (CT) and drilling into ploughed soil.

TL;DR: In organic rotations dominated by cereals, combating of perennial weeds by deep ploughing may be more important than factors such as tractor weight and wheel placement.

TL;DR: In this paper, the authors compared non-renewable energy inputs, energy output, and energy use efficiency of nine dryland cropping systems comprised of a factorial combination of three methods of input management [high (HIGH), i.e., conventional tillage plus full recommended rates of fertilizer and pesticides; reduced (RED), i., conservation tillage, plus reduced rates of nitrogen and pesticides, and organic (ORG),], and three crop rotation systems with varying levels of cropping diversity.
