Abstract

Legumes are among the plant groups that are the most sensitive to weed competition especially during the early growth stages. A severe infestation of weeds (parasitic weeds and perennial grasses) in legumes not only decreases the yield but also causes difficulties in field operations. Climate change has both positive and negative impacts on weed dynamics and management practices in legumes. The change in climate also affect the weed control methods, especially chemical control method by changing the efficacy of herbicides. Legume crops like chickpea (Cicer arietinum), faba bean (Vicia faba), lentil (Lens culinaris), field pea (Pisum sativum), dry bean (Phaseolus vulgaris) and soybean (Glycine max) are less competitive to weeds specially under varying climatic conditions. So effective weed control under the climate change scenario is compulsory to achieve better yield and quality of legume crops. This chapter covers the weed dynamics in legumes, impact of climate change on weed dynamics, critical weed interference period and crop weed competition. Different management approaches (chemical and non-chemical weed control) also discuss under climate change scenario.
