Special Issue Information

Dear Colleagues,

Weed management plays a crucial role in crop production management systems. The use of chemical herbicides has been a common method of weed management, but it has raised concerns about herbicide-resistant weeds, environmental contamination and impacts on human health. In order to develop more sustainable agricultural systems, while also ensuring food security and economic benefits to farmers, research on sustainable weed management practices that not only effectively control weeds but also ensure better yields, reduce costs, and minimize the negative impacts of agriculture on the environment is in critical need.

The aim of the Special Issue is to improve the understanding of sustainable weed management strategies in crop production management systems. It is closely related to the scope of the journal by focusing on addressing challenges in agricultural sustainability, analyzing its environmental and economic impacts, and promoting socio-economic, scientific and integrated approaches to sustainable development.

The themes of the Special Issue are broad as we encourage contributions from researchers in a variety of disciplines. The research subject can be either individual weed control methods (such as crop rotations, mulching, crop diversification, cover cropping, biological control and intercropping) or integrated weed management practices with a combination of multiple weed management methods.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

(1) impacts of weed management strategies on soil health, water quality, biodiversity and other environmental indicators as well as crop yields and farms’ economic returns; (2) socioeconomic and policy factors that influence adoption of sustainable weed management practices; (3) cost and benefits analysis of different weed control methods; and (4) challenges facing sustainable weed management such as herbicide resistance and issues caused by climate change.

I look forward to receiving your contributions.

Cover cropping recently emerged as a promising alternative to conventional tillage and herbicide use for weed suppression in agricultural systems. We investigated their effectiveness in weed control and the varying effects of different management strategies using a meta-analysis. Our analysis studied two categories: weed biomass control and weed density control. We employed a random-effect model to analyze weed biomass to address between-study heterogeneity and found that cover crop treatments led to a significant 62.6% reduction in weed biomass. These results are robust to outliers and publication bias. Furthermore, subgroup analysis found that planting a mixture of cover crop types was more effective than planting a single type. Additionally, planting a mixture of cover crop species, which are subcategories of cover crop types, was found to be more effective than planting a single species. Our analysis also unveiled a persistent, albeit diminishing, reduction in weed biomass even after the termination of cover crops. For weed density analysis, we used a fixed-effect model due to the absence of between-study heterogeneity and found a statistically significant reduction (45.4%) in weed density. Subgroup analysis revealed no significant difference in weed density control between legume and grass cover crop types. Full article

This study examines the impact of weeds on sweet corn, where weeds compete for essential elements, such as nutrients, water, sunlight, and space for growth. In general, the use of herbicides is meant to suppress weed growth. Soil organic matter is important for plant growth and affects herbicide persistence. This study aimed to explore the interaction between ametryn herbicide and soil organic matter content and its impacts on weed growth, herbicide persistence, and sweet corn yield. The experiment was initiated in 2022 at the Experimental Station of the Faculty of Agriculture, Padjadjaran University, Indonesia, using a Split-Plot Design in a Randomized Complete Block Design (RCBD), with three replicates. The experiments consisted of three levels of organic matter, i.e., low, medium, and high, and six levels of ametryn herbicide at 0.0 (control), 0.5, 1.0, 1.5, 2.0, and 2.5 kg a.i./ha. The results indicated that the apparent interaction between ametryn herbicide doses of 1.5, 2.0, and 2.5 kg a.i./ha and the three levels of the organic matter content totally suppressed weed growth. However, the effects of the interaction between ametryn herbicide and organic matter content on the herbicide persistence and the sweet corn yield were not obvious. Ametryn yielded excellent positive results on sweet corn yield. Bioassay analysis showed that the lowest persistence of ametryn herbicide was in line with the highest content of organic matter.
