The economic impacts of second generation Bt cotton in West Africa: empirical evidence from Burkina Faso
West Africa has been slow in adopting agricultural biotechnology. The most progressive stance has been taken by Burkina Faso, which began field testing Bt cotton in 2003. This paper reports the first three years of Bt cotton field trials, which found that Bt cotton increased cotton yields by an average of 20% and reduced insecticide applications by two-thirds. While the technical success of Bt ...

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 ...

Nutrient dynamics from broiler litter applied to no-till cotton in an upland soil
Applying broiler litter to the soil surface of a no-till field of cotton (Gossypium hirsutum L.) increases the potential loss of its nutrients via runoff and volatilization. An experiment was conducted over 3 yr on an upland Atwood silt loam soil (fine-silty, mixed, semiactive, thermic Typic Paleudalfs) near Pontotoc, MS, to determine the effect of broiler litter incorporation into the surface ...

Furrow seeding with plastic mulching increases stand establishment and lint yield of cotton in a saline field
Uniform stand establishment is essential for profitable cotton (Gossypium hirsutum L.) production in saline fields. This study was conducted during 2003 and 2004 to determine if furrow-bed seeding and plastic mulching improve stand establishment and cotton lint yield in a saline field. The experiment was arranged in a split-plot design with seeding patterns (flat-seeded and furrow-seeded) as main ...

Indigo`s Living Map of the World`s Food System
Two weeks ago, at the inaugural Beneficial Ag event in Memphis, Indigo was proud to participate in a growing community of innovators from across the food system. One of the questions we asked ourselves was, “What are the technological capabilities needed to catalyze the beneficial agriculture movement?” We believe a new way for seeing the global food system is part of what’s ...

Can bats reduce nut farmers’ pesticide use?
Ecologist Katherine Ingram is on a quest to quantify the economic value of insect-eating bats in walnut groves. For the past three years, Katherine Ingram has had a most unusual summer job: catching bats and studying their droppings to see what they eat. A doctoral student in ecology at the University of California, Davis, Ingram is exploring the role bats can play as winged soldiers in the ...

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 ...

Balancing demand and crop rotation guides North Carolina family farm
When brothers Wyatt and Frank Scott returned home to their Lucama, North Carolina family farm after earning degrees from NC State University in 2016, they planted 18 acres of sweet potatoes. This year, 200 acres of the root vegetable will be hand harvested off of 46” beds and they have plans to build infrastructure to expand even further. It has become the farm’s number two cash crop ...

New tools and farmer training could revolutionize pesticide management in West Africa
Field schools that train farmers in alternative methods of pest control have succeeded in nearly eliminating the use of toxic pesticides by a community of cotton growers in Mali, according to a new FAO study published today by the London-based Royal Society. The study was conducted in two areas - the Bla region of southern Mali, where FAO established a field school program in 2003, and a second ...
