Information on fluctuations in hive temperature and humidity during bee winter in Tashkent region and feed consumption during winter. Studying all this is very important for the bees to survive and survive the winter.

The average salinity of Jizzakh region in the vicinity of groundwater (1.5 m) under the influence of a newly built closed bed ditch, winter wheat is irrigated 3 times during the season, the current irrigation rate is 823-933 m3 / ha. The norm of seasonal irrigation was 2586 m3 / ha, and the grain yield of winter wheat was obtained depending on the experimental areas, ie the area of the new construction (experimental variant) and the old type of irrigated area (control).  At the same time, the average grain yield in the experimental field was 43.2 t / ha, and in the control field - 40.1 t / ha.

This article discusses the improvement of the development of biotests in saline soils with the addition of zeolite, phosphogypsum, organic fertilizers.  The development of biotests on seawater with a concentration of 1-10 g / l improved when humates, KNO3, and water extracts from crop residues were added to the water. A decrease in the salinity of the upper soil layer is shown when an interlayer with large pores from high moor peat is created at a depth of 25 cm.

This article analyzes further ensuring the country's food security and the impact of the Cornovirus pandemic that shock the whole world on the economy of not only Uzbekistan but also developed countries.

The article presents opinions and comments on the use of collector-drainage networks and water sources in Bukhara region. Their hydromorphological data on the main collectors located in the region are also given. The changes in the flow and mineralization rate of collector-drainage networks were studied. Suggestions and recommendations were also provided in order to increase the efficiency of secondary use of some types of agricultural crops as an additional source of water from the collector-drainage water in Bukhara region.

The article provides information on the current state of exploitation of natural resources of Capparis spinosa L. in Uzbekistan, some results of ongoing research on the introduction of this plant into cultivation in order to create industrial plantations.

The article achieved the chemical efficiency of Entovant 15% em.k., 0,5 l per hectare, Vertimek, 1,8% em.k., 0,5 l, biological efficiency 89,0-90,0%. It is r ecommended to use these preparations at least 25-30 days before harvest.
