Interference between Redroot Pigweed (Amaranthus retroflexus L.) and Cotton (Gossypium hirsutum L.): Growth Analysis
Redroot pigweed is one of the injurious agricultural weeds on a worldwide basis. Understanding of its interference impact in crop field will provide useful information for weed control programs. The effects of redroot pigweed on cotton at densities of 0, 0.125, 0.25, 0.5, 1, 2, 4, and 8 plants m(-1) of row were evaluated in field experiments conducted in 2013 and 2014 at Institute of Cotton Res...
متن کاملInvestigation Corn and Soybean Intercropping Advantages in Competition with Redroot Pigweed and Jimsonweed
The spatial variation in plant species associated with intercropping is intended to reduce resource competition between species and increase yield potential. A field experiment was carried out on corn (Zea mays L.) and soybean (Glycine max L.) intercropping in a replacement series experiment with weed contamination consist of: weed free, infestation of redroot pigweed, infestation of jimsonweed...
متن کاملPoisoning Associated with Ingestion of Redroot Pigweed (Amaranthus ret- roflexus) in Cattle – Case Report
On a farm in Slovenia two cows died overnight without any previous signs of disease. The cows were fed green forage, containing a big portion of redroot pigweed (Amaranthus retroflexus) at least for four consecutive days. Poisoning with this plant was suspected. Pathomorphological changes established by the necropsy of both cows confirmed the suspi-
متن کاملImpact of water deficit on critical period of pigweed (amaranthus retroflexus l.) in sunflower
ABSTRACT-The critical period of weed control is a part of crop life cycle during which weeds must be kept weed-free to avoid yield losses due to competition. In order to evaluate the effect of deficit irrigation on critical period of redroot pigweed (Amaranthus retroflexus L.) in sunflower (Helianthus annuus L.), an experiment was carried out as split plot ba...
متن کاملImpact of Kenaf (Hibiscus cannabinus L.) Leaf, Bark, and Core Extracts on Germination of Five Plant Species
The chemical interaction between plants, which is referred to as allelopathy, may result in the inhibition of plant growth and development. The objective of this research was to determine the impact of kenaf (Hibiscus cannabinus L.) plant extracts on the seed germination of five plant species. Four concentrations (0, 16.7, 33.3 and 66.7 g/L) of kenaf leaf, bark, and core extracts were applied t...
