Article Abstract
Seed weevils ( spp.) are major pests of faba bean, causing yield losses, and affecting marketability. Our objective was to identify stable sources of resistance to seed weevil attacks, determine the climatic factors that most influenced its incidence and its relationship with some phenological and agronomic traits. The accessions "BOBICK ROD115," "CÔTE D'OR," "221516," and "NOVA GRADISKA" showed increased resistance to penetration and development of larvae. Other accessions such as "QUASAR," "109.669," and "223303" exhibited resistance to larval development. The results of this work suggest the presence of different defense mechanisms to seed weevils in faba bean, which in the future could be introgressed in elite cultivars to create resistant varieties and contribute to more sustainable agriculture with less need for pesticides. The temperature, rainfall, and humidity seemed to be the climatic factors most influencing faba bean seed weevil attack while the precocity and the small weight of the seeds were correlated with lower infestation rates in the different experiments.

Background And Aim: The search for sustainable and cost-effective protein alternatives to soybean meal in livestock diets has led to the exploration of legumes such as faba beans [FBs] ( L.). This study investigated the effects of dietary inclusion of FBs on carcass traits, meat quality, and selected blood parameters in Awassi lambs.

In light of the detrimental consequences of climate change and global warming, drought (water deficit) has emerged as a major abiotic stressor that adversely affects plant development, productivity, and sustainable agriculture globally. Vicia faba L. (faba bean), a highly nutritious leguminous crop, is especially vulnerable to water scarcity.

Commercially relevant processing conditions, including protein concentration, pH and shearing and their impact on the solubility, heat stability, and secondary structure of faba bean proteins (FBPIs), were studied. Most of the examined properties, including protein solubility and heat stability, were due to the simultaneous effects of pH and concentration. The shearing rate played a crucial role in determining the heat stability of FBPI during thermal processing through protein molecular activities, such as inter- and/or intramolecular force interactions.

Broad bean is one of the most important leguminous crops worldwide. However, its productivity is greatly affected by the infestation of and (Hemiptera: Aphididae). The main objective of the current study was to identify the most susceptible phenological stages of the broad bean variety (Histal) against black aphids' herbivory.
