A laboratory experiment was conducted at the plant physiology division, Bangladesh Agricultural Research Institute (BARI) during 2019-20 to assess the allelopathic effects of some selected weed species on seed germination and seedling growth of mungbean. Four weed species viz., Durba (Cynodon dactylon), White cock’s comb (Celocia argentia), Shyama (Echinochloa crusgalli), Shak notae (Amaranthus viridis) were used for mungbean (BARI Mug 6).

As chemical weed control became more difficult and expensive, it became necessary to focus on the technique of reducing weed impact, which does not only involve herbicide usage. Aspects such as tillage method, sowing date of crops, crop rotation, weed ecology and germination requirements, amongst other, may play a role in reducing weed impact.

In soil solarization, moist soil is covered with a transparent plastic film, resulting in passive solar heating which inactivates soil-borne pathogen/weed propagules. Although solarization is an effective alternative to soil fumigation and chemical pesticide application, it is not widely used due to its long duration, which coincides with the growing season of some crops, thereby causing a loss of income. The basis of this project was that solarization of amended soil would be utilized more widely if growers could adopt the practice without losing production. In this research we examined three
