EFFECT OF PLANTING AND MINERAL FERTILIZER RATE ON GROWTH AND DEVELOPMENT OF WINTER WHEAT VARIETIES

Abstract

At present, it is necessary to strengthen selection work to create new intensive type local varieties. It is necessary to achieve the production yield of wheat varieties at least 70-80 s/ha and more and to ensure that they give highquality products. Foreign varieties grown in Uzbekistan are also very important. It is necessary to thoroughly study the local varieties and samples of these varieties. Because in order to fully provide the population of our Republic with bread and flour products, it is necessary to selectively plant high-yielding varieties that are resistant to diseases, pests and dormancy, suitable for local conditions. That's why there is a need to create new varieties of intensive type that are suitable for different soil and climate conditions of our Republic. (Sanzar-6) and imported (Polovchanka, Demetra) winter wheat varieties, to jointly study the norms of their planting and the norm of mineral fertilizers and introduce optimal options into production in the future. Further strengthening of grain independence in our republic We believe that it will be a positive step.
