In the articleIt has unique characteristics and characteristics that make it an endangered species of agricultural cropspear "Zukhra" restoration of local varieties, researches were conducted in order to establish nursery gardens for the propagation of seedlings.

"Zukhra" variety of pear, the results of research on determining the level of biological compatibility of seedlings, cultivar-graft combinations are presented. In the experiment, Zukhra and Azamat varieties of pear were grafted on seed seedlings, quince A, VA-29 and Ghox-9 grafts, and their ability to hold buds was studied. The high capacity of buds was noted in the Zukhra variety grafted on the Ghox-9 rootstock. It was observed that high results were achieved in the Zukhra variety grafted on standard seedlings Ghox-9.

From the studied varieties of lemon, the variety Pervenets Uzbekistan stood out in all respects, from the varieties of orange, the variety Korolek Pear-shaped 20 centners per hectare stood out in terms of yield, and from the varieties of mandarin, the variety Okitsu Wase stood out.

Before conducting field experiments, we tested dimilin against the gypsy moth in laboratory conditions. In this experiment, only the worms of the pest were taken.

In the version where Dimilin was used, when the drug was used at a concentration of 0.015% of the working liquid, the biological efficiency reached 70.2% by the 7th day of calculation, and when it was used at a concentration of 0.02% of the working liquid, the efficiency was 85.1% by the 7th day of calculation. When the drug Dimilin was used at a working liquid concentration of 0.03%, the biological efficiency reached 89.6% by the 7th day of calculation.

The agreeable things of plant improvement - benefit rhizobacteria ANd an Endomycorrhiza (AM) vegetation ( Glomus fasciculatum ) on plant improvement , yield, and supplement take-up of T. aestivum not entirely settled in field conditions. The triple antibody of Azotobacter chroococcum with eubacteria and Glomus fasciculatum extensively extended the dry matter by two.6-overlay on top of the administration. Grain yield of plants immunized with A. chroococcum related to eubacteria sp. furthermore, G. fasciculatum was 2-overlap more than that of non-vaccinated plants, at a hundred 35 days while planting (DAS). the most expansion in grain supermolecule (255.2 mg g) not entirely settled in that frame of mind with A.
