MASTER'S DISSERTATION ABSTRACT
Relevance of the topic. Today, in the
world agricultural practice, it is
possible to save
valuable nitrogen fertilizers, enrich the soil with organic
substances, and improve the structural condition by growing soybeans. 150-250 kg
of atmospheric nitrogen will be absorbed by the bacteria
during the season when
inoculants (preparations of tuganac bacteria) are used on 1 hectare of soybean
planted area. This amount of nitrogen is equivalent to 510-850
kg of ammonium
nitrate. The nitrogen accumulated by the bacteria is considered biological nitrogen
and it does not pollute the environment, nitrates do not accumulate in the products,
it ensures the increase of useful microorganisms in the soil,
the reduction of
pathogenic microflora, the costs of nitrogen fertilizers are saved, resource-efficient
technologies are used. opportunities for development and introduction to
production will expand.
In this regard, one of the priority tasks is the wide
application of sowing soybeans using inoculants in the
scientifically based crop
rotation system, the development of resource-saving technologies that allow to
grow ecologically clean products and increase the profitability of the field.
Soybeans are being widely planted in our republic in order to meet the needs
of
the population for food, livestock and poultry feed and to increase the
productivity of crops in the field of rotation. In the Action Strategy of the Republic
of Uzbekistan for 2017-2021, it is important to "...consistently develop agricultural
production, further strengthen the country's food security, expand the production of
environmentally friendly products, significantly increase the export potential of the
agrarian sector" defined as strategic tasks. For this reason, it is urgent to improve
the rate of mineral fertilizers and the method of using biological preparations in the
feeding of soybean varieties grown in the irrigated
areas of our republic, and to
conduct scientific research on this.
