Early establishment increases yield and fiber quality of industrial hemp (Cannabis sativa L.) produced in the Mid‐Atlantic

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Planting dates (PDs) are well established for a wide range of agronomic crops to maximize yield and quality, but this guidance is lacking for industrial hemp (Cannabis sativa L.) produced for fiber, especially in the Mid‐Atlantic region.

Weed Control in Corn (Zea mays L.) as Influenced by Preemergence Herbicides

open access: yesInternational Journal of Agronomy, 2016
Field studies were conducted in central and south-central Texas from 2013 through 2015 to evaluate crop tolerance and efficacy of various preemergence herbicides alone and in combination for weed control in field corn. Acetochlor and pendimethalin alone,

Nitrogen fertilizer placement and its influence on snap bean production in North Florida

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract In sandy soils or areas with abundant rainfall, nutrients tend to leach from where plant roots grow. Nitrogen (N) is a mobile element that is consistently at risk of being lost to the environment. In the spring of 2023, a controlled‐release fertilizer (CRF) study with two locations was undertaken at the North Florida Research and Education ...

Effects of pre- and post-emergence weed control on weed population and maize yield in different tillage systems

open access: yesPlant, Soil and Environment, 2003
The effect of chemical weed control with reduced herbicide rates (pre-em., pre-em. + post-em., post-em.) on weed population density and maize yield was compared in three tillage systems (mouldboard, chisel, disk harrowing) for lessive pseudogleyic soil ...

Leaching behavior of metolachlor in soil

open access: yesJournal of Environmental Engineering and Science, 2004
This work estimated the leaching behavior of metolachlor from montmorillonite-based and commercial emulsifiable concentrate (EC) formulations in soil columns and field plots by using bioassay and chemical techniques. A montmorillonite-based formulation of metolachlor was prepared by adsorbing metolachlor to montmorillonite–benzyltrimethylammonium ...

Nitrogen and weed management in transplanted tomato in the Nigerian forest-savanna transition zone [PDF]

open access: yes, 2018
Weed infestation and inherent low soil fertility are among primary reasons for low yields of tomato in Nigeria. Field trials were carried out during the wet season of 2015 and 2016 to evaluate yield response of tomato to nitrogen (N) application and weed

Assessing the Efficacy and Safety of Preemergence Herbicides Applied Alone or in Combination with Superabsorbent Polymer, Soil Binding Agent, and Compost in Tomato (Solanum lycopersicum L.) Plasticulture Production

open access: yesHortScience
Preemergence herbicide application under plastic mulch is an effective way to manage weeds in tomato (Solanum lycopersicum L.) production. Nonetheless, applying herbicides beneath plastic mulch in raised beds is associated with the inherent risk of crop ...
