Descripción

Management practices that increase the competitive ability of crops with weeds are important components of integrated weedmanagement systems. Weeds can greatly impact crop yield through direct competition for water, sunlight, and nutrientresources. Practices that affect one factor in a cropping system can impact others. Tillage practices can affect weed speciescomposition, and weed species composition in turn can affect the critical period of weed control in a given crop (Halford et al.2001). Understanding the impact tillage and cropping systems have on weed management will help in determining optimal cropproduction practices. It is important to understand the biology and growth characteristics of plant species that make them strongcompetitors with crops. While biology and ecology are common research areas, weed physiology is an often overlooked area ofresearch in weed research. It is important to understand the effects that environmental factors have on the physiology of weedyspecies. Effective weed management programs that integrate all components of the production system including planting date,crop rotation, tillage regime, soil nutrient amendment application, and weed control measures. Sustainable weed managementpractices will be critical in the success of this emerging crop production area as weeds are one of the most limiting factors inestablishing a healthy competitive crop, especially in perennial crop establishment and production (Fischer et al. 1988; Hall et al.2004). Investigating weed species and their management in row crops and emerging bioenergy crops is important to the NorthCarolina State University mission to secure food and fiber, enhance profitability in agriculture, and providing environmentalstewardship. Developing effective, economical, and environmentally sound weed management systems for North Carolinafarmers will contribute to the fulfillment of the this mission.
