- Comparison of Yield, Maturity, Value and Susceptibility to TSWV in Virginia- and Runner-Type Varieties of Peanut in 2004Phipps, P. M.; Coker, Dennis L.; Faircloth, Joel C. (Virginia Cooperative Extension, 2005-09-01)Discusses a 2004 study conducted comparing two varieties of peanuts, Virginia- and Runner-type, on the basis of yield, maturity, value, and susceptibility to tomato spotted wilt virus over the course of a growing season.
- Cotton Harvest Aid Selection and Application TimingFaircloth, Joel C.; Sanders, Jason; Wilson, Henry P. (Virginia Cooperative Extension, 2009)Discusses methods to determine when a cotton crop is ready for defoliation.
- Defoliating Cotton under Adverse Conditions: Drought-stress, Cool Temperatures, and Rank GrowthSanders, Jason; Faircloth, Joel C.; Wilson, Henry P. (Virginia Cooperative Extension, 2009)Discusses use of defoliants as a harvest aid for cotton, what types of defoliants to choose in relation to drought, and cool temperatures, and leaf growth.
- Individual Experiments to Evaluate the Effects of Plant Population and Planting Date, Cultivar and Plant Growth Regulator Application, and Herbicide and Plant Growth Regulator Application on Cotton (Gossypium hirsutum L.) Growth and Development, Yield, and Fiber QualityO'Berry, Nathan Brook (Virginia Tech, 2007-06-21)Cotton (Gossypium hirsutum L.) growth and development, lint yield, and fiber quality are influenced by many management decisions. Three field experiments examining the interaction of plant population and planting date, and cultivar or herbicide and plant growth regulator application on these parameters were conducted in Virginia during 2005 and 2006 and in North Carolina, South Carolina, and Louisiana during specific years. Experiment I: Plant Population and Planting Date Lint yields were highest with populations of 8.9 and 12.8 plants m¯² compared to 5.3 plants m¯² in Virginia and North Carolina, while in Louisiana the highest yields resulted from populations of 5.8 and 9.5 plants m¯² compared to 17.1 plants m¯². Earlier planted (1 May) cotton produced higher yields relative to later planted (21 May) cotton in Louisiana, while yield was not influenced by planting date in Virginia and North Carolina. The impact of plant population and planting date on cotton appeared to be influenced significantly by heat unit accumulation. Experiment II: Cultivar and Mepiquat Pentaborate Application Mepiquat pentaborate (MPB) application consistently decreased plant height, HNR, and enhanced maturity for all cultivars, compared to untreated cotton. A trend of decreasing yield with increasing MPB application in Virginia was observed. These data suggests that cotton response to MPB application is influenced by cultivar maturity or fruiting interval. Experiment III: Trifloxysulfuron-sodium and Mepiquat Chloride Application Trifloxysulfuron-sodium (TFS) did not influence vegetative growth, maturity, or yield in comparison to untreated cotton. Mepiquat chloride (MC) application reduced vegetative growth and enhanced maturity in most years. The results of this experiment demonstrate that TFS application does not have the same effects on plant growth as MC application.
- Perennial Grass Based Crop Rotations in Virginia: Effects on Soil Quality, Disease Incidence, and Cotton and Peanut GrowthWeeks, James Michael Jr. (Virginia Tech, 2008-04-24)In 2003 eight peanut and cotton crop rotations were established in southeastern Virginia, 4 of which included 2 or 3 years of tall fescue or orchardgrass grown as high-value hay crops. Each crop rotation was evaluated for changes in soil quality indicators including soil carbon and nitrogen, water stable soil aggregates, plant available water content, bulk density, cone index values, and soil moisture. Cotton and peanut growth and yield were also observed to evaluate changes in crop growth associated with differences in soil quality. Soilborne plant pathogens including root-knot nematode, stubby root nematode, ring nematode, stunt nematode, and Cylindrocladium parasiticum microsclerotia were measured in the spring and fall of each year to determine differences associated with crop rotations. Water stable soil aggregates in 2007 were higher in rotations with 3 years of either perennial grass. Soil moisture tended to be the highest at depths 30 - 60 cm in the 3-year tall fescue rotation in August and September 2007. Cotton in 2006 and peanut in 2007 had higher growth and yield where the annual crop directly followed a perennial grass. Root-knot nematode tended to decrease in all rotations over time. Stubby root nematode populations tended to increase in rotations with either duration of orchardgrass. Including perennial grasses in cotton and peanut rotations has the potential to increase growth and yield as demonstrated in this research.
- Virginia Cotton Production Guide, 2008Faircloth, Joel C.; Herbert, D. Ames Jr.; Phipps, P. M.; Roberts, Mike (Virginia Cooperative Extension, 2008)This manual offers recent data on fertilizers to use, tillage practices, planting dates, replanting, cotton varieties, control of diseases, pest insects, and weeds, and harvest-aids and estimates on crop production costs.
