Europe accounts for around 20% of the global cereal production and is a net exporter ca. 15% that production. Increasing demand cereals justifies questions as to where by how much Europe's can be increased meet future market demands, additional nitrogen (N) crops would require. The latter important environmental concern legislation are equally aims in Europe. Here, we used country-by-country, bottom-up approach establish statistical estimates actual grain yield, compare these modelled...
Nitrogen (N) fertilizers are one of the most expensive inputs in agricultural settings. Additionally, loss N increases costs, contributes to soil acidification, and causes off-site pollution air, groundwater waterways. This study reviews current knowledge about technologies for fertilization with potential increase use efficiency reduce its negative effects on environment. Classic inorganic sources such as urea ammonium sulfate major utilized, while controlled release have not been...
Winter wheat (Triticum aestivum) is one of Switzerland's most important field crops and requires large quantities nitrogen (N) to produce a high yielding high-quality crop. However, N an expensive input for producers that prone environmental losses, thus causing pollution degradation. Furthermore, the use efficiency (NUE) remains low. Our goals were test whether different fertilizer splits could maximize grain yield content (a proxy quality) while improving efficiency, identify key variables...
Transgenic plum trees (Prunus domestica) containing the pox potyvirus coat protein (PPV-CP) gene were inoculated with PPV by aphid feeding or chip budding. Infection was monitored evaluation of virus symptoms, DAS-ELISA, and immunoblot assays. Based on observations analyses over 3 years including two dormancy cycles, one out five transgenic clones (C-5), found to be resistant infection whether aphids could not detected in any plants C-5 clone immunocap-ture-reverse transcriptase-polymerase...
Variety mixtures represent a promising option to sustainably increase the productivity of grain cropping systems, but underlying processes driving potential yield benefits remain poorly understood. Notably, role variety-specific phenotypic changes in - defined here as plasticity and their effects on plant-plant interactions has scarcely been evaluated. Here, we examined trait responses 8 Swiss wheat varieties when grown mixtures, how these plastic contributed overyielding, complementarity...
<title>Abstract</title> Wheat and maize productivity gains depend on accurate estimates of genetic trends, genotypic effects (G), genotype-by-environment interactions (GEI). Here, we compiled a unique European Value for Cultivation Use (VCU) database wheat (2003–2018) to estimate G GEI magnitudes, variety-testing precision in grain yield using mixed-model methodology. We found that variances were comparable across Europe, with variety-comparison precisions 0.29–0.56 t ha<sup>-1</sup> (wheat)...
Identifying opportunities and limitations for closing yield gaps is essential setting right the efforts dedicated to improve germplasm agronomic practices. This study analyses genotypes × environments interaction (G E), genetic progress, grain stability under contrasting production systems. For this, we analyzed datasets obtained from three Swiss trial-networks of winter wheat that were designed evaluate organic farming conditions, conventional management with low-inputs (150 kg nitrogen (N)...
Abstract In the face of climate change, improving yield stability is critical for food production systems. Increasing diversity in agricultural systems can be a way to stabilize across time and/or space. This done with mixtures varieties, which represent practical introduce at genotype level fields. However, Switzerland, wheat variety are still rarely used, due lack understanding processes driving benefits and, consequently, no clear rules as varieties combine. this study, we used results...
Plum pox potyvirus, the cause of most destructive and feared viral disease Prunus, (plum or Sharka) has been established in North America. Following recognition symptomatic peach fruit positive confirmation causal agent October, 1999, an official announcement presence dreaded Adams County, Pennsylvania was made jointly by Animal & Plant Health Inspection Service Department Agriculture. strains are capable causing peaches, plums, apricots, nectarines, almonds, sweet sour cherries, as well...
Abstract Data leakage is a common issue that can lead to misleading generalisation error estimation and incorrect hyperparameter tuning. However, its mechanisms are not always well understood. In this work, we consider the case of clustered data investigate distribution number elements in when set uniformly split. For both validation test sets, first second moments derived analytically. Modelling consequences investigated exemplified on simulated data. addition, an actual agronomic...

ABSTRACT Wheat ( Triticum aestivum L.) grains are widely used as a feed. Contrasting to the demand of high viscosity for bread making, low is required monogastric livestock. The impact genotype and climate on this trait largely unknown. Therefore, seven wheat varieties grown at five sites in Switzerland from 2007 2009 were analyzed potential applied viscosity, that is, after inactivation plants’ own enzymes. covered wide range thus representing different classes quality. Agronomical traits...
Abstract Marketed as a healthier alternative to soft wheat, spelt ( Triticum aestivum ssp. spelta) is in increasing demand from consumers and bakers Switzerland. The Swiss landscape currently dominated by two varieties – Ostro Oberkulmer Rotkorn considered references for “typical” spelt. However, these are rather old deliver low yields; the market therefore needs improved with higher agronomic potential while keeping essential attributes of typical As winter wheat can be interbred, modern...
In the current quest for a more sustainable, environment-friendly agriculture, variety mixtures are often suggested as practical option to increase stability of food production systems. Their effects on yield have been extensively researched, yet clear conclusions remain elusive, notably in terms mechanistic processes and optimal combinations. Furthermore, case wheat, is not only component equation: grain quality crucial bread value chain, wheat its rarely investigated. To that end, we...
