Weeds represent a major problem for the production of food legumes in Morocco. In order to cover its legume needs, the country currently imports this commodity, particularly lentils (Lens culinaris Medik.). The present study was conducted to investigate the effects of some agroecological strategies, such as manual weeding, fer- mented nettle extr...

Bearing in mind the negative impacts of intensive farming systems based on monoculture and heavy chemical usage, there is a need to find sustainable agroecological practices (AP). The introduction of legume crops through intercropping practices, mulching, and plant water extracts are among the non-chemical strategies for agroecological weed managem...

The powders of Ammi visnaga L. and Calendula officinalis L. plants collected from Meknes region were subjected to three types of analysis, including FTIR analysis, CHNS/O analysis, and ICP-AES analysis with the aim of comparing and giving an insight into the nutritional value, medicinal properties, and potential applications in different fields. Th...

Abstract The aim of this study was to investigate qualitative and quantitative chemical compounds of plant water extract (PWE), and the reduction potential of Corum herbicide (bentazone and imazamox) doses using PWE for weed control in faba bean fields. Chemical analysis revealed the presence of diverse allelochemicals including polyphenols, flavon...

Promoting well-functioning ecosystems that maintain the sustainability of agricultural systems in response to climate change remains a major challenge in North Africa. Agroecological practices have the potential to serve as an alternative to chemicals. However, there are gaps in our knowledge regarding these practices in North Africa that need to b...

The use of excessive chemicals in agriculture can cause harm to the environment and human health.
