Interactions between pre- and post-emergence weed harrowing in spring cereals

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...

effect of pre- and post-emergence herbicides and their combination on weed control and yield of safflower (carthamus tinctorius l.)

in 2007, an experiment was conducted at the farm of the college of agriculture, isfahan university of technology, in najaf abad (lavark), to study the effects of two pre-emergence herbicides (trifluralin and ethalfluralin) when combined with the three post-emergence herbicides setoxydim, cycloxydim and haloxyfop and the two post-emergence herbicides desmedipham and phenmedipham on weeds and the...

Structure of weed communities occurring in crop rotation and monoculture of cereals

A strict field experiment with crops sown in crop rotation and monoculture wascarried out in the years 1988-2012 at the Experimental Station Uhrusk belonging tothe University of Life Sciences in Lublin, south-eastern Poland. The study wasaimed at evaluating the structure of weed communities occurring in crop rotationand monoculture of cereals. The highest weed density m-2 was determined inthe s...
