Abstract. The effect of nanopreparations on the seed properties of propagated varieties of cotton is studied. For research, the cotton variety Andijan-36 was used, which is sown on the Ok- Suv farm. The seeds of indo-sampling of the harvest of 2017 were taken and sown in 2018, as a nursery of the first year. In 2019, the collected families of the nursery of the first year were sown in the nursery of the second year. The data obtained for two years of research showed that the use of nanopolymer preparations has a positive effect on the growth, development and productivity of plants, does not affect the varietal qualities of seeds and have a certain degree of plant protection from diseases. It was proposed to use the following nanopolymer preparations for encapsulation: PMCСu2+Ag7:3(Polymer metal complex), PMCСu2+Ag8:2, nanochitosan and nanoascorbate chitosan, which showed higher yields compared to the control and the standard.
Key words: laboratory and field germination, phenological observations, nanopolymers, varietal purity, growth, development, productivity.
