Faba bean is mainly grown under rain-fed conditions, although irrigated production is important in Egypt, parts of China and Central Asia. China is the leading producer with a wide range of intensive rotation and inter-crop holistic cropping systems...

Chickpea (Cicer arietinum L.) is an important food and rotation crop in many parts of the
world. Cold (freezing and chilling temperatures) and Ascochyta blight (Didymella rabiei)
are the major constraints in chickpea production. The effects of...

Lentil (Lens culinaris Medik.) is an important food legume crop in Syria. Fusarium wilt (Fusarium oxysporum f.sp. lentis – Fol) is a key yield-limiting factor in the country. The genetic diversity of Fol population was studied using 96 isolates...
