Critical time for weed removal in dicamba tolerant soybean as influenced by pre emergence herbicides

Critical period of weed control in soybean (Glycine max) as influenced by starter fertilizer

The critical period of weed control (CPWC) in crops depends on many factors including supply and availability of nutrients. In order to investigate the effect of starter fertilizer on the CPWC in soybean a field experiment in a randomized complete block design with four replications in a factorial arrangement was conducted at the Agricultural Research Farm of Razi University, Kermanshah, Iran. ...

The Efficiency of Integrated Pre-Emergence and Post-Emergence Herbicides in Nutrient Uptake by Wheat and Nutrient Depletion by Weeds in Sesame-Wheat Cropping System in Khuzestan

In order to investigate the effect of pre-emergence and post-emergence herbicides on nutrient depletion, weed population and nutrient uptake by wheat in sesame-wheat cropping system in Khuzestan a field experiment was conducted in randomized complete block design with three replications in the research farm of Shahid Chamran University of Ahvaz in 2019-2020. Treatments included no weeding, hand...

Efficacy of Pre-Emergence and Post-Emergence Soybean Herbicides for Control of Glufosinate-, Glyphosate-, and Imidazolinone-Resistant Volunteer Corn

Glyphosate-resistant corn and soybean are grown in rotations in the Midwest, including Nebraska. Volunteer corn is a problematic weed in soybean fields because it causes harvest problems, reduces yield and seed quality, and potentially harbors insects, pests, and diseases. Several pre-packaged herbicides have been registered in soybean in recent years, but response of volunteer corn to these he...

Seedling emergence and growth of sugarbeets as influenced by surface and incorporation applications of petroleum mulches

Real-time Soil Profile Water Content as Influenced by Weed-corn Competition

Weeds compete with crops for belowground resources; however, there is little detailed information on relative dynamics of soil water during competitive interactions. This research was conducted to determine changes in soil-water storage (CSWS) in rain-fed no-tillage corn (Zea mays L.) production in the presence or absence of weed competition over two droughty growing seasons. Weeds at the exper...
