Abstract HAMM, GARY STEPHEN. Agronomics of Cotton Grown on a 38-cm Row Spacing in North Carolina (Under the direction of Dr. Keith Edmisten). Cotton (Gossypium hirsutum) planted in a 38-cm row configuration is an innovative idea that has come about in the past few years. There has been some interest in narrow-row cotton due to the availability of a new harvester capable of harvesting cotton on 38-cm rows. Producers have raised questions regarding changing their cotton production strategies in order to maximize yield potential for cotton grown on 38-cm rows. Agronomic practices that allow for maximum yield potential have yet to be determined for narrow-row cotton. Four separate field experiments were conducted in 2005, 2006 and 2007 at Upper Coastal Plains Research Station, near Rocky Mount, NC, Central Crops Research Station, Clayton, NC, and Duplin County, NC in order to define these agronomic practices. Cotton was planted on 38-cm row spacings using a vacuum planter. One experiment was conducted to observe the effects of seven nitrogen rates ranging from 0-196 kg N ha-1 on yield potential, plant uptake of nitrogen, growth habits, fiber quality, and economic returns of narrow-row cotton. The second experiment was conducted to look at the effects of fourteen different application methods on plant height control, yield, and fiber quality. The strategies consisted of making applications to narrow-row cotton at certain growth stages with different rates of mepiquat pentaborate. The third experiment consisted of making a herbicidal defoliation application to narrow-cotton at six different percent open boll stages ranging from 0-100 % open bolls to determine yield and fiber quality parameters. The fourth experiment was conducted to determine if narrow-row cotton could be planted in a double crop situation with wheat which is an uncommon practice in NC. For this experiment, narrow-row cotton was planted in comparison with wide-row cotton for yield and economic potential a.

Book Description
In light of public concerns about sustainable food production, the necessity for human and environmental protection, along with the evolution of herbicide resistant weeds, call for a review of current weed control strategies. Sustainable weed control requires an integrated approach based on knowledge of each crop and the weeds that threaten it. This book will be an invaluable source of information for scholars, growers, consultants, researchers and other stakeholders dealing with either arable, row, cash, vegetables, orchards or even grassland-based production systems. The uniqueness of this book comes from the balanced coverage of herbicide effects on humans and environment in relation to best weed control practices of the most important cropping systems worldwide. Furthermore, it amalgamates and discusses the most appropriate, judicious and suitable weed control strategies for a wide range of crops. It reviews the available information and suggests solutions that are not merely feasible but also optimal.
