Overexpression of Glutathione reductase in cotton does not alter emergence rates under temperature stress
Cotton (Gossypium hirsutum L.) seedlings are considered to be sensitive to temperature stress. The exposure of plants to high and low temperatures can result in the production of reactive oxygen species that contribute to diminished plant performance. Plants have mechanisms that metabolize oxidants into less harmful chemicals, and enhancement of antioxidant metabolism has been shown to be ...

A dynamic model of cotton emergence based on the thermal dependence of malate synthase
Cotton (Gossypium hirsutum L.) is frequently planted when temperatures are not optimal for germination and emergence. Delayed emergence, a common contributor to diminished plant performance later in the season, is often related to nonoptimal temperatures. Improvement of cotton performance requires knowledge of the source, pattern, and magnitude of thermal limitations on seedling metabolism. In ...

The Future Of The Hydroponic Systems
The hydroponics, which had its expansion in the early 70s in order to increase productivity and growing in adverse geographical locations, has a long way to go. Some advances in the hydroponic systems has been made recently at the last frontier: space. At the International Space Station (ISS), water and food are limited resources affected by the cost, transport time and storage. The hydroponic ...

Cotton Planting date: yield, seedling survival, and plant growth
New cultivars, changes in technology and production practices, and climate change may have altered the optimal planting time for cotton (Gossypium hirsutum L.) in the midsouthern United States. A field experiment was conducted from 2002 through 2005 on Gigger silt loam to define planting date (PD) effects on selected cotton cultivars. Six cultivars in 2002 (Deltapine DP555BR and Delta Pearl, ...

Solid and skip-row spacings for irrigated and nonirrigated upland cotton
Producers of upland cotton (Gossypium hirsutum L.) are interested in alternative row spacings and planting patterns to improve productivity. We conducted factorial experiments for 3 yr in adjacent irrigated and nonirrigated fields at Milan, TN, of cotton grown in 25-, 76- and 102-cm rows, each planted in a solid and 2 x 1 skip-row pattern. Narrower rows and solid plantings tended to close canopy ...

Subsurface drip and overhead irrigation: a comparison of plant boll distribution in upland cotton
Although subsurface drip (SSD) is used as a water-efficient alternative to overhead irrigation in many crops, the effects of SSD on the distribution of bolls on cotton plants (Gossypium hirsutum L.) have not been thoroughly examined. The purpose of this study was to add to the current knowledge about the effects of SSD on cotton yield dynamics. Cultivar DP 488 BG/RR was grown in three studies ...

Root-knot nematode-resistant alfalfa suppresses subsequent crop damage from the nutsedge-nematode pest complex
Southern root-knot nematode [RKN, Meloidogyne incognita (Kofoid & White) Chitwood], yellow nutsedge (YNS, Cyperus esculentus L.), and purple nutsedge (PNS, C. rotundus L.) occur together as a mutually beneficial pest complex in sandy soils. All crops grown in infested soils are affected due to the wide host range of the nematode, the perennial life cycle of the nutsedges, their interactions, ...

Canopy gas exchange measurements of cotton in an open system
A portable, open transparent chamber system for measuring canopy gas exchanges was developed and tested. Differentials between incoming and outgoing atmospheric H2O and CO2 concentrations were used to calculate canopy transpiration (E) and net assimilation (A) at 10-s intervals using solenoid valve actuated sample lines connected to an infrared gas analyzer. A programmable data logger controlled ...

Impact of varying planting Dates and tillage systems on cotton growth and lint yield production
As economic conditions deteriorated, cotton (Gossypium hirsutum L.) producers have looked to improve profit margins by reducing inputs while maintaining yields. Pairing the yield benefits from early planting with the input reductions from conservation tillage might help accomplish those goals. The objective was to determine how growth, lint yield, and fiber quality were impacted by planting ...

Does skip-row planting configuration improve cotton net return?
Cotton (Gossypium hirsutum L.) growers want information about alternative planting configurations to reduce seed, technology, and other production costs. We evaluated the impact of solid and 2 x 1 skip-row configurations on net returns for cotton grown in 25-, 76-, and 102-cm rows based on yield and fiber quality data from an experiment in adjacent nonirrigated and irrigated fields at Milan, TN. ...

Method for Trimming Riccia fluitans and Glossostigma elatinoides
Riccia fluitans and Glossostigma elatinoides are the two most common varieties in the aquatic plant world, and they are the species that people prefer more when they choose to plant water grass.When breeding such kinds of aquatic plant species, in addition to scientific and reasonable care, but also regular trimming. Cut off the aging and rotten leaves, so that the new leaves can grow normally, ...

Steering for Yield, Comfort in the Field
The return on investment of GPS automated steering systems is almost never argued anymore. GPS technology has been proven to reduce overlap, resulting in fuel savings and productivity gains that farms of all sizes can appreciate. However, in my experience, the leading reason that farms today invest in a steering system is operator comfort. Many providers in the agricultural industry offer ...

A closer look at AMCO’s versatile Ditcher cutter heads
Standing water can kill crops in a hurry. That’s why a well-built drainage system is essential, especially if you: Live in a flat area or region with a lot of precipitation Plant corn, soybeans, cotton, rice, or other crops that are sensitive to waterlogging AMCO’s Vertical and Offset Rotary Ditchers are affordable tools that easily clean roadside ditches and reshape waterways. ...

Comparative plant growth and development in two cotton rotations under irrigated and non-irrigated conditions
Incorporating perennial grasses such as bahiagrass (Paspalum notatum Fluegge) to diversify the conventional two-crop rotation of peanut (Arachis hypogaea L.) and cotton (Gossypium hirsutum L.) prevalent in the U.S. Southeast (SE) is advocated. However, little is reported on growth and development for cotton grown in rotation with perennial grasses. Our objectives were to compare plant ...

Crop response to rotation and tillage in peanut-based cropping systems
Production of peanut (Arachis hypogaea L.) in reduced tillage systems has increased in the United States during the past decade. However, interactions of tillage system and crop rotation have not been thoroughly investigated for large-seeded, Virginia market type peanut. Research was conducted at two locations in North Carolina during 1999 to 2006 to compare yield of corn (Zea mays L.), cotton ...
