The Critical Period of Weed Control in Faba Bean and Chickpea in Mediterranean Areas

Abstract: Weeds are often the major biological constraint to growing legume crops successfully, and an understanding of the critical period of weed control (CPWC) is important for developing environmentally sustainable weed management practices to prevent unacceptable yield loss. Therefore, we carried out two field experiments to identify the CPWC for two grain legume crops traditionally grown in Mediterranean areas: chickpea and faba bean. The experiments were conducted at two sites both located in the Sicilian inland … Show more

“…The reduction in total weed seed density detected in W F compared with W W is difficult to explain. In fact, compared with wheat, faba bean has a sparser canopy (as a result of a greater row spacing) and a slower growth rate in the early stages of the crop cycle, both characteristics that favour the emergence and growth of weeds (Frenda et al ., ); moreover, during the faba bean growing season, weeds were controlled mechanically by shallow hoeing, which did not always guarantee an optimal result (Giambalvo et al ., ). Therefore, it seems that the negative aspects were widely counteracted by the positive effects of disturbance.…”

“…The number of weeds seems not to affect the yield of the field pea and field bean, which are in line with the yields expected. In fact, these crops are quite competitive against weeds and, in particular, the field bean has a minimum critical period of weed control (Frenda et al, 2013) and both field bean and pea have a great capacity of soil cover (Tavoletti et al, 2004). This aspect makes these crops particularly interesting for organic cultivation.…”

“…Na cultura do feijão não é diferente: na quase sua totalidade, no período entre 2012 e 2013 foi utilizado o nível arbitrário de 5% de redução na produtividade (Ghamari & Ahmadvand, 2012;Parreira et al, 2012Parreira et al, , 2013Bressanin et al, 2013;Frenda et al, 2013). No Brasil, a análise econômica tem pouca demanda, mas gera muito interesse na atual conjuntura econômica.…”
