      Weed control treatments affected rice plant density in the aman season but not in the boro season.

In both seasons, the lowest plant density was found in . 4 Integrated weed management (IWM) is a strategy for weed control that considers the use of all available weed control techniques, including preventative measures, monitoring, crop rotations, tillage, crop competition, herbicide rotation, herbicide mixtures, biological controls, nutrition, irrigation, burning, etc. IWM does not solely rely upon herbicides for weed control.

    Major challenges in organic rice production include nutrient optimization, weed management and variety selection [5]. Weed competition is one of the prime yield limiting biotic constraints in rice [6]. Uncontrolled weed can reduce rice yield by 44% to 94% [7]. Weeds even can cause total crop failure [8].   Integrated weed management practices in rice include: Land preparation: Thorough land preparation can significantly decrease the incidence of weeds in rice by destroying all weeds and weed seeds to provide weed-free conditions at the time of planting, and providing a good environment for rapid growth of rice seedlings.

    The book provides details on harnessing knowledge of weed ecology to improve weed management in different crops and presents information on opportunities in weed management in different crops. Current management practices are also covered, along . Rice allelopathy depends on variety and origin: Japonica rice is more allelopathic than Indica and Japonica-Indica hybrid. More recently, critical review on rice allelopathy and the possibility for weed management reported that allelopathic characteristics in rice are quantitatively inherited and several allelopathy-involved traits have been.
