UAV-Based Multi-Label Weed Detection for Site-Specific Weed Management Using a Multi-Scale Convolutional Attention Network

Agronomy
Accurate weed detection is essential for site-specific weed management because uncontrolled weeds compete with crops for water, nutrients, light, and growing space, while uniform herbicide application increases production costs and environmental pressure.

‘The most advanced outpost of cultivation’: palynological evidence for cereal agriculture and population resilience in a marginal upland environment

Journal of Quaternary Science, EarlyView.
ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...

RIMPhil: a bioeconomic model for integrated weed management of annual barnyardgrass (Echinochloa crus-galli) in Philippine rice farming systems [PDF]

This paper describes a complex, dynamic simulation model that has been developed for the analysis of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli) in rice farming systems in the Philippines.

Glyphosate as a Tool for the Incorporation of New Herbicide Options in Integrated Weed Management in Maize: A Weed Dynamics Evaluation

, 2019
A farm-scale investigation was conducted to evaluate the potential impact of integrating glyphosate into different weed management programs when cultivating herbicide-tolerant maize in central Spain from 2012 to 2014. The weed management programs were (1)

Interactive Effects of Subsidiary Crops and Weed Pressure in the Transition Period to Non-Inversion Tillage, A Case Study of Six Sites Across Northern and Central Europe

Agronomy, 2019
Reducing soil tillage can lead to many benefits, but this practice often increases weed abundance and thus the need for herbicides, especially during the transition phase from inversion tillage to non-inversion tillage.

Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

Prospects for site specific weed management

, 2014
Research on Site Specific Weed Management (SSWM) started in the late 80's. Since that moment, considerable research has been conducted on different aspects of SSWM, from fundamental studies on the spatial ecology of weeds to the applied development and ...

Modelling individual plants’ growth: competition of Viola arvensis and wheat

Frontiers in Agronomy
IntroductionCompetition by weeds is a severe threat to agricultural crops. While these days the broadcast of herbicides over the entire field is common praxis, new technologies promise to reduce chemical output by reducing the area sprayed.

Phytochemical composition and cultivar‐dependent variation in colored lettuce (Lactuca sativa) and their α‐amylase inhibitory activity

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study investigated cultivar‐dependent variation in the phytochemical composition of lettuce (Lactuca sativa) using liquid chromatography–tandem mass spectrometry (LC–MS/MS) profiling and high‐performance liquid chromatography (HPLC) quantification, with a focus on enzyme inhibitory activity. RESULTS Significant differences were

Economics of the Variable Rate Technology Investment Decision for Agricultural Sprayers [PDF]

Producers lack information about the profitability of variable rate technology (VRT) for agricultural sprayers. An economic framework was developed to evaluate the returns required to pay for VRT investments.
