Performance of different wheat varieties and their associated microbiome under contrasting tillage and fertilization intensities: Insights from a Swiss long-term field experiment

Winter wheat is an important global cereal crop. However, conventional farming practices, characterised by intensive tillage and high fertilizer inputs, pose significant threats to the environment. In response, more conservative management practices are being applied aiming to maintain wheat production while promoting a beneficial microbiome. Here, we evaluated the suitability of three different wheat varieties for less intensive agricultural systems, focusing on reduced tillage and fertilizer intensity. The study was conducted over two consecutive years in a Swiss long-term field experiment comparing conventional versus reduced tillage and full fertilization versus half fertilization. In addition, we investigated the composition of plant-associated microbial communities using amplicon sequencing of phylogenetic marker genes, specifically targeting bacteria and fungi in rhizosphere samples and fungi in root samples. Our results revealed that in our study wheat variety most strongly predicted grain yield and quality, independent of tillage and fertilization intensity. Specifically, wheat varieties demonstrated higher yields and N uptake in plots subjected to conventional ploughing and full fertilization compared to those under reduced tillage and half fertilization. We found no significant effect of wheat variety on the composition of microbial communities. However, tillage emerged as the primary factor influencing microbial community composition in the rhizosphere, while fertilization intensity significantly impacted fungal communities in the root system. These findings underscore the complex interplay between agronomic practices, plant genetics, and microbial dynamics in agroecosystems, emphasizing the need for holistic and adaptive approaches and their further development to ensure sustainable crop production

Farmer-participatory design and assessment of multispecies intercrops of cool-season grain crops

Multispecies mixtures of crops are challenging to design and manage due to the complex relationships between species in the mixtures. Both practical and biological obstacles arise when agriculture moves from monoculture to polyculture crops. However, crop mixtures could provide a tool to stabilize yield fluctuations, increase diversity and resilience, and support ecological intensification in organic farming. The general objective was to design and evaluate together with organic farmers, grain and forage mixtures for Northern and Southern Europe on the basis of crop use, management factors, phenology, plant type and expected compatibility, using earlier data and knowledge, scientific literature and farmers’ experience. All designed mixtures were tested experimentally under organic farming to verify the agronomic value and farmers’ acceptability of the crop mixtures. The advantages and challenges related to the crop mixtures in terms of the total crop yield, management practices and a range of other aspects of their agricultural performance were determined. This report summarizes the most promising multispecies grain legume-based mixed crops developed in the project and their agronomic performance in the field experiments in Northern and Southern Europe. The advantages of crop mixtures over pure stands are discussed along with practical issues related to mixed crops investigated and agroecological measures

Brennfleckenkrankheit bei Malven

Der Anbau von Malven (Malva sylvestris) als Heil- und Gewürzpflanze spielt in der Schweiz eine wichtige Rolle. Sowohl die Blätter als auch die Blüten sind reich an Schleimstoffen, die sich bei der Behandlung von zahlreichen Krankheiten wie Erkältungen oder Rachenentzündungen, bewährt haben. Aber auch die Pflanze selbst ist anfällig für Krankheiten. 2024 kam es zu Ernteausfällen aufgrund der Brennfleckenkrankheit, ausgelöst durch den Pilz Colletotrichum malvarum

Dataset derived from publications on organic crop yields compiled in project OrganicYieldsUP WP3

This dataset is part of the database compiled as an outcome of Work Area 1 in project OrganicYieldsUP. Variable definitions can be found here: https://doi.org/10.5281/zenodo.15276082 Work Package 3 (WP3) of the OrganicYieldsUP project focused on compiling off-site data from peer-reviewed scientific literature to complement the on-site experimental data gathered in WP2. The goal was to identify, extract, and structure data on yield-enhancing strategies under organic management across Europe and comparable climate zones. This process was essential for broadening the project’s evidence base and informing subsequent analysis and modelling activities in WP4 and WP5. WP3 followed a systematic approach aligned with PRISMA methodology to ensure transparent and consistent literature screening. A total of 751 publications were initially identified based on defined search criteria. After applying inclusion and exclusion filters, 170 studies passed the first screening phase. From these, data were successfully extracted from 60 scientific publications and entered into the standard WP2/WP3 data template developed in WP1. The screening of published scientific papers focused on papers published between 2009 and 2024. This time frame was chosen to ensure the use of the most current and relevant studies reflecting recent developments in organic farming methods, data quality standards, and policy frameworks. The screening prioritized English-language publications to maintain consistency in terminology and ensure broad understanding across project partners. Only original peer-reviewed research articles were considered, including case study reports where applicable. The search excluded reviews, editorials, and opinion papers due to the risk of duplicating data already included in WP2. Studies needed to focus explicitly on the impact of organic crop management strategies on yields. Only field trials, long-term experiments, and case studies were included, while pot experiments and single-year studies were excluded to avoid misleading conclusions caused by seasonal anomalies or short-term effects. All included studies had to come from Europe or similar climate zones such as North America or North Africa. During initial screening, titles, abstracts, and keywords had to contain terms related to "yield" and "organic" to be considered relevant. Full-text screening followed, using specific keywords aligned with the WP1 database. Only studies containing the obligatory data fields identified in WP1 were accepted. Publications that had already been included in the WP2 analysis were not considered again in WP3
