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 ...

Weeds are a major obstacle to successful crop production in organic farming. Producers may be able to reduce inputs for weed management by designing rotations to disrupt population dynamics of weeds. Population-based management in conventional farming has reduced herbicide use by 50% because weed density declines in cropland across time. In this paper, we suggest a 9-year rotation comprised of ...

A Research Committee was established by the Weed Science Society of America to outline the direction of weed science research during the next decade. Weeds adversely affect humans in both agricultural and nonagricultural environments. It is the opinion of the research committee that weed science will be advantageously positioned for the future if research focuses on research decision processes,...

An experimental machine vision-based patch-sprayer was developed. This sprayer was primarily designed to do real-time weed density estimation and variable herbicide application rate control. However, the sprayer also had the capability to do high-resolution weed mapping if proper mapping techniques being integrated. Two weed mapping methods were developed. One is GPS signal-based off-line weed ...

in order to study the effects of wild mustard density on grain yield and yield components of canola cv. hyola 401 under different rates of nitrogen fertilizer, a field experiment was conducted in 2011-2012. the layout was split-plot in a completely randomized block design and three replications. main-plots included four levels of nitrogen (0, 70, 140 and 210 kg ha-1) and sub-plots consisted of ...

Context Knowledge gaps exist for the interference of Avena ludoviciana and Argemone mexicana in chickpea grown eastern Australia.Aims This research aimed to examine effect different levels A. their potential cause yield loss chickpea.Methods Experiments were conducted a randomised complete block design with five weed infestation both weeds (none, low, medium, high, very high) three replications...

the aim of this research was to compare more and less competitiveness of rice cultivars against barnyardgrass for light extinction coefficient and canopy structur. a filed experiment was conducted in 2007 growing season in tonekabon’s rice research station in mazandaran province. the experiment layout was a factorial design with four randomized complete blocks. seven rice cultivars (khazar, sep...
