Sugar beet yield loss predicted by relative weed cover, weed biomass and weed density [PDF]
Plant Protection Science, 2017 Sugar beet yield loss was predicted from early observations of weed density, relative weed cover, and weed biomass using non-linear regression models. Six field experiments were conducted in Germany and in the Russian Federation in 2012, 2013 and 2014 ...

Effect of crop establishment methods and weed management practices in rice on weed density, weed dry weight and weed control efficiency [PDF]
International Journal of Chemical Studies, 2021 A field experiment was conducted at Agronomy Main Research Farm, Department of Agronomy, College of Agriculture, OUAT, Bhubaneswar during kharif and rabi 2016-17 and 2017-18. The experiment was laid out in a split plot design with three replications by taking 24 treatment combinations in rice with four crop establishment methods in the main plot and ...

Ancient varieties can help control weed density while preserving weed diversity
Biological Agriculture & Horticulture, 2023 Weeds are a major component of agricultural diversity affecting crop yield and ecosystem services. Compared to modern wheat (Triticum aestivum) varieties, ancient wheat cultivars (released before 1960) are taller, and this trait can be used to control weeds in organic farming systems.
