"Sorghum Bicolor is a cereal used for grains as feed and food, mainly cultivated in dry areas. To study the possibilities of increasing its cultivation for feed purposes, ecological, morpho-agronomical, and bromatological characterization of some local ecotypes was conducted as the first steps toward selecting better cultivars. Indeed, twenty-one ecotypes were collected from farms in Northern Morocco ...

Abstract : "Body size is a trait that can affect plant–pollinator interaction efficiency and plant reproductive success. We explored the impact of intraspecific size shifts on the interactions between pollinators and flowering plants under controlled conditions. We considered two development conditions leading to the production of large and small individual flowers of Borago officinalis and Echium ...
Ecological, morpho-agronomical, and nutritional characteristics of Sulla flexuosa (L.) Medik. ecotypes

"The present work was part of assessing wild genetic plant resources of forage interest in Northern Morocco and aimed to study the agro-morphology and nutritional value of Sulla fexuosa (L.) Medik. (Hedysarum fexuosum L.) ecotypes. The seeds of twenty-one wild S. fexuosa (L.) Medik. ecotypes were collected from 21 sites. The edaphic and climatic characteristics of the collection sites were studied ...
Que nous apprend cette 1ère mesure de l’activité biologique des sols ?
Publication d'intérêt général/presse
"Évaluer la fertilité des sols n'est pas trivial. Très souvent, on résume cela à une série de mesures physico-chimiques telles que le pH, la granulométrie (texture), la richesse en éléments nutritifs (P, K, etc.) ou le statut organique (teneur en carbone total). Cette approche a ses avantages car elle se base sur des procédures éprouvées et bien souvent standardisées, relativement rapides et stables ...
