To reduce the risks of climate change, governments agreed in Paris Agreement to limit global temperature rise less than 2.0 °C above pre-industrial levels, with ambition keep warming 1.5 °C. Charting appropriate mitigation responses requires information on costs mitigating versus associated damages for two levels warming. In this assessment, a critical consideration is impact crop yields and yield variability regions currently challenged by food insecurity. The current study assessed impacts...
Abstract Conventional tillage (CT) is a widely used agricultural practice aimed at loosening soil to enhance water infiltration and root growth. However, it can lead environmental issues such as increased erosion loss of nutrients carbon. To address these challenges, non‐conventional systems like no‐tillage minimum (collectively referred NT) have gained popularity in recent decades. This review examines the effects CT NT on root: shoot ratio (R:S) based 28 studies covering common crops...
Abstract Background and aims Intercrops offer multiple advantages over sole crops. The aim of our study was to characterize root growth interactions in spring wheat/faba bean intercrops better understand belowground that govern resource capture. Materials methods A field experiment conducted with one faba cultivar two wheat cultivars sown at three sowing densities, defining intercropping designs. Destructive coring (0–100 cm) the crops development stages. FTIR spectroscopy used discriminate...
Nitrogen (N) and phosphorus (P) deficiencies can significantly reduce crop yield. Despite their importance, the impacts of N P under field conditions on cereal roots, particularly winter rye, remain poorly understood. This study investigates effects rye growth root architecture conditions. A sampling campaign was conducted during 2022 season at long-term fertilizer experiment Dikopshof, Germany. Four treatments were chosen: (1) fully fertilized with manure (NPKCa+m+s), (2) without (NPKCa),...
<title>Abstract</title> Aims. We investigated the effects of N and P deficiencies on winter rye growth root architecture under field conditions. Methods. Sampling was conducted during 2022 season at long-term fertilizer experiment Dikopshof, Germany. Four treatments were chosen: (1) fully fertilized including manure (m) supplemental mineral (s) (NPKCa + m s), (2) without (NPKCa), (3) omitted (_PKCa), (4) (N_KCa). Shoot biomass topsoil biomass, number tillers, nodal number, angle, length...
In low input agriculture, a thorough understanding of the plant-nutrient interactions plays central role. This study aims to investigate effects nitrogen (N), phosphorus (P), and potassium (K) liming omission on shoot growth as well topsoil root biomass, morphology (tuber fibrous roots) sugar beet grown under field conditions at Dikopshof long-term fertilizer experiment (Germany). Classical observation methods were combined with link measurements using an image analysis program. Omission...

Cereal-legume intercrops have numerous advantages over monocultures. However, the intercrop's performance depends on plant genotypes, management, and environment. Process-based agro-ecosystem models are important tools to evaluate of intercrop systems as field experiments limited in number treatments. The objective this study was calibrate a new process-based model using an extensive experimental data set test whether is suitable for comparing management strategies. includes all combinations...

Better matching of the timing and amount fertilizer inputs to plant requirements will improve nutrient use efficiency crop yields could reduce negative environmental impacts. Deep learning can be a powerful digital tool for on-site real-time non-invasive diagnosis deficiencies. A drone-based RGB image dataset was generated together with ground truthing data in winter wheat (2020) rye (2021) during tillering booting long-term experiment (LTFE) Dikopshof. In this LTFE, crops are fertilized...
While it is widely recognized that nitrogen (N), phosphorus (P), potassium (K), and lime (Ca) are crucial for high agricultural yields soil fertility, there a lack of field studies examining shoot-root responses to deficiencies. Understanding crop adaptation strategies nutrient-poor soils essential managing low-input agriculture. In this study, we compared the shoot root winter wheat cultivated in two growing periods (2019/20 2020/21) at long-term fertilizer experiment Dikopshof, Germany...
