    Wheat against weeds and windstorm on small farms
    Weeds and windstorm - double scourge to wheat crop of the smallholders in Durmon village in the cold winter desert of Uzbekistan
    2021
    Also available in:

    The publication explores the damage caused by both a windstorm and weeds to wheat harvest of the farmers in Durmon village in the cold winter desert of Uzbekistan. Improved variety of wheat crops has been introduced to smallholders through Farmer Field Schools, implemented jointly with the International Center for Agriculture Research in Dry Areas (ICARDA) and FAO.

    The extent of damage due to weeds depends on the type of weeds, crop stage, and duration of competition between weeds and wheat crop. In an early (September) planted wheat crop, weeds can be a problem before winter and should be controlled. A greater weed problem occurs in spring after winter rainfall and when not possible to walk in the field. Weed infestation that occur before winter can become a serious problem in early spring making it difficult to control due to high density and extensive growth of both weeds and wheat crop

    Food security and nutrition can only be assured if it is based on sustainable production practices and crop seeds of good quality and purity. Good quality seeds are needed on farm as a major asset to boost crop yields. However, availability of good quality seeds largely depends on investment by the private sector, which depends on availability of a significant market to ensure profit. But, enforcement of different national seed legislations, which is the case in many countries, for example in Africa, does not provide a seed market large enough to attract investment from the private sector. In this context, the Food and Agriculture Organization of the United Nations (FAO) encourages and supports regional harmonization of rules governing quality control, certification and marketing of crop seeds. While regional harmonization enlarges the seed market and makes it attractive for investment by the private sector, care must be taken to upgrade the seed standards b y insertion of the list of dangerous seed borne pests, pathogens and weeds, to anticipate on their possible spread over entire regions. With regard to weeds, contamination of crop seeds by weed propagules is an important issue in several countries in Africa, Asia and Latin America. Contamination of crop seeds by weed propagules contributes to spreading of weeds to places where they were not encountered before, which increases weed management cost incurred by the farmer, may take land out of production and may become an impediment to sustainable crop production intensification.
