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...
Accurate estimation of the size and spatial distribution yield gap has many practical applications, including relevance to precision agriculture technology targeting. The objectives this study were illustrate a methodology create map discuss its potential uses provide optimal crop management recommendations farmers. We used HybridMaize simulation model estimate for maize grown in winter season northwestern Bangladesh. This is high yielding environment, where farmers achieve yields as 12...
The challenges of securing future food security will require deployment innovative technologies to accelerate crop production. Plant phenotyping methods have advanced significantly, spanning low-cost hand-held devices large-scale satellite imaging. Field-based aims capture plant response the environment, generating data that can be used inform breeding and selection requirements. This in turn requires access multiple representative locations capacities for collecting useful information. In...
Abstract The application of visible and near‐infrared (vis–NIR) spectroscopy to characterize soil samples has gained growing interest as a fast cost‐effective methodology for fertility assessment. In order profit from the full potential vis–NIR spectroscopy, acquisition spectra directly in‐situ would increase possibility obtain data rapidly at high spatial temporal resolution. present study, we test propose best practice set fertility‐related parameters (i.e. texture, organic carbon, pH,...
ABSTRACT Ensuring food security through sustainable practices while reducing greenhouse gas emissions are key challenges in modern agriculture. Utilising genetic variability within a crop species to identify varieties with higher root biomass carbon (C) could help address these challenges. It is thus crucial quantify and understand intra‐specific above‐ belowground performance under varying environmental conditions. The study objectives were to: (a) depth distribution different winter wheat...
<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)...
Food security and economic stability of many developing countries rely on the resilience major crops to climatic variability anomalies. Since climate change forecasts predict an increasing frequency intensity disturbances, need increase our knowledge about influence crop productivity is especially acute for areas with fragile environments such as semi-arid sub-humid Chaco in South America. We used records from recent decades growth models to: (i) identify main variables that have influenced...
Congregated information on maize and wheat root morphology their distribution as influenced by tillage soil physical conditions is meager. Root growth under no-tillage (NT) or conventional (CT) variable: Under NT, higher bulk density slows elongation provides shorter roots but simulate branching; results may be opposite depending texture. CT, compaction have negative effects growth, with exhibiting plasticity. In humid climates, low temperatures can reduce length (RLD) increase the diameter...
Four spring wheat genotypes (Triticum aestivum L.) were grown without (N0 = 0 kg N ha−1) and under ample (N1 250 nitrogen (N) fertilizer in field experiments two seasons. The aim was to assess genotypic variation use efficiency (NUE) components N-related indices during grain filling thus identify superior genotypes. Leaf chlorophyll (SPAD) readings at crucial growth stages employed help differentiate Interrelations between yield with SPAD, where also assessed explain possible pathways of...
Roots take up most of the resources required by a plant, but lack efficient research tools hinders our understanding function and relevance root system. This is especially evident when focus not on single multiple plants that share same soil resources. None available methods allow for simple, inexpensive, non-destructive, objective assignment observed roots in mixture to target plant. Here, we demonstrate transgenic expressing green fluorescent protein (GFP), combined with well established...
Abstract The nitrogen (N) fertilization of wheat ( Triticum aestivum L.) is important for stable and high grain yield. However, the effect N on root growth survivorship poorly understood. objectives this study were (1) to determine varying availability roots (2) whether genotypic variation in N‐related traits are linked survivorship. In a two‐year study, two spring cultivars (Albis Toronit) an experimental line (L94491) grown under low (20 kg ha –1 ) supply (270 lysimeters equipped with...
