- Abstract:
- ... Field studies were conducted in Alabama in 2016 and 2017 to determine the effect of postemergence applications of glufosinate alone and glufosinate applied with S-metolachlor, using two different nozzle types, on LibertyLink®, XtendFlex®, and WideStrike® cotton growth and yield. Two applications of glufosinate at 0.6 kg ha–¹, and glufosinate with S-metolachlor at 1.39 kg ha–¹ were applied to each ...

- Abstract:
- ... Agricultural producers and scientists have long recognized both beneficial and detrimental aspects of soil tillage. With the development and adoption of herbicide-resistant crops, particularly glyphosate-resistant crops, herbicides such as glyphosate replaced the need for tillage either before or after crop planting. Thus, tillage has become less important for weed management and has been a primar ...

- Abstract:
- ... Palmer amaranth is the latest pigweed species documented in Connecticut; it was identified there in 2019. In a single-dose experiment, the Connecticut Palmer amaranth biotype survived the field-use rates of glyphosate (840 g ae ha⁻¹) and imazaquin (137 g ai ha⁻¹) herbicides applied separately. Additional experiments were conducted to (1) determine the level of resistance to glyphosate and acetolac ...

However, PPO-inhibitor herbicides can injure the crop under certain application conditions, especially under abiotic stress and surfactants may exacerbate this injury. The objectives of this study were to 1) investigat ...

Adoption of new production methods to address these conditions can produce higher or lower yields, as well as differing cotton (Gossypium hirsutum L.) fiber quality. The objective of this study was to evaluate the effect of row spacing, her ...

- Abstract:
- ... Previous research has indicated that conservation tillage is a viable option for suc‐ cessful peanut production; however, interactions between cover crop residues and peanut growth are not fully understood. Additional information is needed about the effects of varying levels of cover crop biomass on peanut growth and develop‐ ment. Level of cover crop residue may also affect the preemergence herbi ...

- Abstract:
- ... In Alabama, typically, a three-wk period is required after rolling down a cover crop to achieve termination rates >90%, and to eliminate competition for water between the cover crop and cash crop. Cover crop termination can be sped up by applying herbicides during the rolling process. However, for organically grown cotton, synthetic herbicides cannot be used. This experi- ment evaluated the effect ...

Of the 157.7 million ha of cropland across the United States (U.S.) in 2012, approximately 127.5 million ha were harvested. Roughly 44% of total cropland area used conservation tillage practices, including no-tillage. In 1989, there were approximately 0.34 ha ...
