This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than a century, farmers planted cotton in rows spaced 91-cm or more apart. Row spacing was dictated primarily by equipment for cultivation, which was initially draft animals and later, tractors. Harvesting equipment also was designed to accommodate these wide row spacings. Recent advances in technology, especially herbicide-resistant cotton and the ability to spindle-pick cotton in 38-cm rows, have increased the potential for cotton production in narrow rows. Field experiments were conducted to evaluate weed management systems in glufosinate-resistant cotton planted in 38- and 97-cm rows. Greater than 90% control of annual grasses and Amaranthus spp. in 2004 and Ipomoea spp. in both years was obtained in narrow-row cotton receiving glufosinate applied early postemergence (EPOST) and mid-postemergence (MPOST) to 2- and 6-leaf cotton, respectively. With good early season control by glufosinate and rapid canopy closure, there was little benefit from pendimethalin, fluometuron, or pyrithiobac applied preemergence (PRE), S-metolachlor or pyrithiobac mixed with glufosinate applied MPOST, or trifloxysulfuron applied late postemergence (LPOST) to 11-leaf cotton. In 2005, glufosinate alone applied EPOST and MPOST did not adequately control annual grasses and Amaranthus spp. Pendimethalin applied PRE alone or mixed with fluometuron or pyrithiobac increased control to greater than 90% and increased yields 59 to 75%. Pendimethalin PRE followed by S-metolachlor or pyrithiobac mixed with glufosinate at MPOST was no more effective than pendimethalin alone. Without PRE herbicides, trifloxysulfuron applied LPOST increased Amaranthus but not annual grass control. Cotton row spacing had no effect on cotton yield and little effect on weed control. Weed control and yield in narrow-row cotton with a PRE herbicide plus glufosinate applied twice was similar to that in wide-row cotton with a PRE herbicide, glufosinate applied twice, and trifloxysulfuron plus prometryn plus MSMA app.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Our image of plants is changing dramatically away from passive entities merely subject to environmental forces and organisms that are designed solely for the accumulation of photosynthate. Plants are revealing themselves to be dynamic and highly sensitive organisms that actively and competitively forage for limited resources, both above and below ground, organisms that accurately gauge their circumstances, use sophisticated cost-benefit analysis, and take clear actions to mitigate and control diverse environmental threats. Moreover, plants are also capable of complex recognition of self and non-self and are territorial in behavior. They are as sophisticated in behavior as animals but their potential has been masked because it operates on time scales many orders of magnitude less than those of animals. Plants are sessile organisms. As such, the only alternative to a rapidly changing environment is rapid adaptation. This book will focus on all these new and exciting aspects of plant biology.

Book excerpt: This is the latest book in the Natural Heritage of Scotland series from Scottish Natural Heritage (SNH). The book contains the papers read at SNH's 2008 conference on the subject and provides the reader with valuable, high quality, up-to-date information and research on the subject, interspersed with stunning full colour images. The long-term aim for all species management is for thriving and self-sustaining, self-regulating populations of native species throughout their natural ranges. The challenge is to achieve this in the face of increasing pressures from developments, exploitation, habitat loss and climate change.This book explores the challenges and solutions to species management for species conservation, the control of invasive non-native species, resolving conflicts of interest between native species, and the sustainable use of species, with contributions from a range of international experts including scientists, conservationists and managers.
