description: Two field experiments were conducted in two successive seasons, 2005/2006 and 2006/2007, to determine whether management can improve faba bean competitiveness with weeds, thus helping to achieve its yield potential. The experiment included five treatments, composed of organic and mineral fertilizers, alone and mixed at different rates, along with a control and six weed control treatments, including oxadiargyl, prometryn, hand hoeing treatments alone or mixed with the herbicides, and a nonweeded treatment (control).The herbicide treatments were not superior to the two hand-hoeing treatments. Using compost favored growth and yield of faba bean more than of weeds. Adding fertilizer also improved most yield parameters. Application of compost alone or combined with 50 or 100% of the recommended NPK rate improved faba bean growth in terms of net assimilation rate, specific leaf area, and leaf weight ratio as components of relative growth rate. This improvement in growth resulted in increase of seed yield, yield components and protein of faba bean. Faba bean yield performance improved under interactive fertilizer effects and weed control treatments as growth improved, as a result of nutrient release from fertilizers and weed control.Dois experimentos em condições de campo foram conduzidos em duas épocas sucessivas - 2005/2006 e 2006/2007 - para determinar se o manejo pode melhorar a competitividade do feijão-fava contra plantas daninhas e contribuir para um maior potencial de produção. Os experimentos incluíram cinco tratamentos, compostos de: fertilizantes orgânicos e minerais, isoladamente ou em mistura em diferentes doses, além do tratamento controle, e seis tratamentos de controle de plantas daninhas, incluindo tratamentos usando oxadiargyl, prometryn, manualmente ou misturados com os herbicidas e um tratamento sem plantas daninhas (controle). Os tratamentos com os herbicidas não foram superiores aos dois tratamentos manuais (hand hoeing).O uso de composto favoreceu o …
