The Impact of Different Crop Rotations by Weed Management Strategies’ Interactions on Weed Infestation and Productivity of Wheat (Triticum aestivum L.)

Weed infestations significantly reduce the growth and yield of field crops. Herbicides are mostly used for weed management due to their quick results. However, resistant biotypes available herbicides rapidly increasing around word. This situation calls development alternative strategies. Crop rotation allelopathic water extracts regarded as most important Therefore, this two-year study assessed impact different annual crop rotations by strategies’ interactions on infestation productivity wheat crop. Wheat was planted in five rotations, i.e., (i) fallow-wheat, (ii) rice-wheat, (iii) cotton-wheat, (iv) mungbean-wheat (v) sorghum-wheat. The strategies included were; false seedbed, application 12 L ha?1 plant (1:1:1:1 ratio sorghum, sunflower, mulberry eucalyptus), herbicide application, weed-free (weed control) weedy-check (no control). Herbicide effective treatment lowering densities biomass during both years followed while were least effective. lowest noted sorghum-wheat cotton-wheat mungbean-wheat, fallow-wheat had highest infestation. Weedy-check caused significant reduction yield, whereas grain recorded from treatments. Grain after sorghum suppressed; however, improved when mungbean. Planting mungbean a environment, achieved through chemical and/or mechanical means, is best strategy obtain higher yields.
