Weed interference in annual cropping systems can be highly variable from year-to-year, as well as spatially heterogeneous. These factors have confounded efforts to develop simple methods for predicting competitive outcomes early in the growing season. A 2-year study was conducted with maize in competition with four annual weed species (Setaria faberi, Abutilon theophrasti, Chenopodium album and...

a field study was conducted to evaluate the effect of haloxyfop-r-methyl ester doses in different grass weeds in various growing stages in safflower during 2011-2012 growing season in research farm of college of agriculture, shiraz university. the study was carried our as split split plot based on randomized complete block design with three replicates. the main factor, sub factor and sub sub fa...

Autonomous robotic weed control systems hold promise toward the automation of one of agriculture’s few remaining unmechanized and drudging tasks, hand weed control. Robotic technology may also provide a means of reducing agriculture’s current dependency on herbicides, improving its sustainability and reducing its environmental impact. This review describes the current status of the four core te...

Despite weeds are a serious threat to promotion of organic farming, relatively less attention is given to research on weed management. This article explores a scope of integration of conservation agriculture for weed control and soil protection under organic farming. Limitation in the use of agro-chemicals under OF promotes intensive tillage for weed control. Mostly, tillage leads to depletion ...

An overview of a decision support system for growing malting barley without use of pesticides is given. One module in this system is the decision support system for mechanical weed control in malting barley. The system is constructed as a Bayesian network. The Bayesian network is used because it gives the possibility to include information on uncertainty in an easily understandable form. The mo...

introduction bean is one of the most important legumes worldwide for direct human consumption and is a rich source of protein and carbohydrates. bean is weak to compete with weed because of the retard growth at the early stages. therefore, weed control at this time plays an important role to gain high priduction. yield crop depends on weed number, and size after germination. weed control depend...
