Integrated weed management (IWM) advocates the use of a combination of preventive, cultural, mechanical, and chemical tools to keep weed pressure below threshold levels that reduce yields and profits. Herbicide tolerant crops (HTCs) represent a relatively new weed control technology that can be used in an integrated weed management program. These crops, which enhance weed control options and gr...
in order to compare the performance of different weed mangement methods in spring and waiting planting of rainfed chickpea this experiment was carrid out as split plot in randomized complete block design with four replications at maragheh agricaltural research station during 2004–2005 crop season. the main factors were planting ِdates including the waiting and spring planting. sub plots were wee...
to evaluate integrated weed management on yield and weed biomass of bean an experiment were conducted as a split plot based on randomized complete block design with three replications at the research station of agriculture in damavand in 2014.main plot of the mechanical control (cultivation)levels including the application and no application of cultivator and sub-plots chemical control levels ...
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...
field experiments were conducted in amirkabir sugarcane agro-industry (khuzestan province, iran) farms to evaluate the efficacy of integrated chemical and mechanical methods in controlling weeds. experiments were carried out in a split plot-randomized complete blocks design with four replications. the main plot consisted of four mechanical treatments, namely: hilling up, sweep cultivator, disc ...
Typically, low-pressure sprayers are used to uniformly apply pre- and post-emergent herbicides to control weeds in crop rows. An innovative machine for weed control in inter-row and intra-row areas, with a unique combination of inter-row cultivation tooling and intra-row band spraying for six rows and an electro-hydraulic side-shift frame controlled by a GPS system, was developed and evaluated....
In the conventional methods of herbicide and fertilizer application, a substantial amount of toxic chemicals is sprayed or broadcast into the furrows, which is later washed away by irrigation water and may contaminate ground water, human and animal environment. If herbicide and fertilizer application could be limited to the most needed parts of the field rather than overall broadcasting, the me...
