Abstract:
... The anticipated release of Enlistᵀᴹ cotton, corn, and soybean cultivars likely will increase the use of 2,4-D, raising concerns over potential injury to susceptible cotton. An experiment was conducted at 12 locations over 2013 and 2014 to determine the impact of 2,4-D at rates simulating drift (2 g ae ha⁻¹) and tank contamination (40 g ae ha⁻¹) on cotton during six different growth stages. Growth ...

Abstract:
... Cotton (Gossypium hirsutum L.) net photosynthetic rate (PN) decreased with leaf age and low irradiance, and the interaction of these factors might lead to decreased yields mainly in crops with a high plant density. Shade decreased leaf gas exchange, mainly in young leaves, which did not recover after exposure to an increasing irradiance. Old leaves reached PN saturation at a lower irradiance than ...

Abstract:
... Interest in using poultry litter (PL) as a nutrient source for row crop production has increased in the southeastern United States. Poultry litter is generally broadcasted on the soil surface. This practice exposes N to volatilization and P to loss with surface water runoff, which potentially negatively impacts the environment. Placing PL in narrow bands below the soil surface has been shown to re ...
