Prediction of cardinal temperature by nonlinear regression models in carrot (Daucus carota L.) and three common weed species [PDF]

علوم و فناوری بذر ایران, 2019
Carrot is a particularly difficult crop to manage in terms of weed control. For weed management of carrot, seed germination is a key process because it determines both the number of weeds that could potentially emerge and the timing of their appearance ...

Soybean yield loss and economic thresholds due to glyphosate resistant hairy fleabane interference

Arquivos do Instituto Biológico, 2018
: The interference of glyphosate resistant hairy fleabane (Conyza bonariensis) has caused yield losses in soybean crop. Knowledge of the economic threshold is an important aspect for the economic management of resistant weeds.

Effects of irrigated cover crop cultivation period on common bean and soybean yield

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Cover crop inclusion is essential for improving soil management in tropical no till systems; however, the optimal duration of irrigated off‐season cultivation remains uncertain. This 3‐year field study evaluated nine cover crop species or mixtures and four cultivation periods (60, 75, 90, and 105 days) on biomass production, soil chemical ...

Control of flaxleaf fleabane (Conyza bonariensis) in wheat and sorghum

, 2010
Flaxleaf fleabane is a difficult-to-control weed in dryland minimum tillage farming systems in the northeast grains region of Australia. Experiments were conducted between 2003 and 2005 to identify effective control strategies on flaxleaf fleabane in ...

Evaluation of leaf surface structure and control of Conyza spp. by herbicides applied in soybean pre-plant burndown [PDF]

Brazilian Journal of Biology
The pre-plant burndown of Conyza spp. is a fundamental practice to mitigate weed competition with soybean. However, in light of reports of biotypes resistant to 2,4-D, the search for new options of post-emergent herbicides becomes essential.

Glyphosate Resistance Affect the Physiological Quality of Conyza bonariensis seeds [PDF]

Planta Daninha, 2019
: High seed production and dispersal capacity and glyphosate resistance are among the main factors that have made hairy fleabane (Conyza bonariensis) one of the most important and dispersed weeds in the world.

The Importance of Spatial Variability in Estimating Evapotranspiration From a Subalpine Wetland

Hydrological Processes, Volume 40, Issue 3, March 2026.
Spatial trends in evapotranspiration were quantified in a sub‐alpine wetland, with higher rates occurring in the wetlands' western portion. This spatial variability suggests care must be taken when estimating evapotranspiration via point measurements. The METRIC approach to modelling evapotranspiration performed reasonably well and should be explored ...

Experimental methods for wind tunnel studies of seed dispersal by wind

Applications in Plant Sciences, Volume 14, Issue 1, January-February 2026.
Abstract The complexity and variability of natural environments make quantitative studies of seed wind dispersal challenging. Wind tunnel experiments offer a controlled alternative to investigate the mechanisms of seed wind dispersal. This review focuses on wind tunnels and the associated technologies used for studying seed wind dispersal, including ...
