For the experiment, a variety of cotton named Andijan-35 was taken, and the variants
were carried out in 3 rounds. The total area was 5 hectares and the seedling thickness was 80-90
thousand / ha. According to the data on the growth and development of cotton, variant 1 cotton
was 90.9 cm tall, the yield of branches was 10.0, the number of yield elements was 4.2, and the
number of pods on September 1 was 6.0. The highest rate was observed in option 3, which was
105.5 cm, 13.2 units, 6.1 units, and 8.3 units, respectively. The results for the remaining options
are given in Table 1.
According to the results of the experiment, the determination of cotton yield was
determined by 3 manual harvesting of the crop. In the control variant, the 1st harvest was found
to be 29.2 q/ha, and the average cotton yield was 34.6 q/ha. In Option 2 (Ferphenol) the average
cotton yield is 39.0 q/ha, in Option 3 (Ferben-potassium) it is 39.7 q/ha, and in Option 4 (Ferben-
sodium) it is 40, 8 q/ha, in options 5 and 6 it was 40.3 and 39.0 q/ha, respectively.

Experiments have shown that cotton has better retention of yield elements than control
when using stimulants and liquid fertilizers during the application period. As a result, it was
found that the yield of cotton increased by 5-6 q/ha, and as a result, economic efficiency was
achieved.
Today, a great deal of work is being done in the customs system to bring Uzbekistan's
international economic relations to the level of developed countries. In the implementation of
foreign economic relations, that is in the process of export and import of goods, each commodity
is classified according to international code numbers on the basis of the nomenclature of goods,
based on a harmonized system. The scientific work carried out by scientists of the Republic in
this area is noteworthy. Honored Inventor of Uzbekistan, Doctor of Chemical Sciences,
Professor I.R. Askarov and Doctor of Technical Sciences, Professor T.T. Rizkiev created the
specialty "Classification and certification of goods on the basis of chemical composition", which
led to the further development of chemistry and it was included in the "Nomenclature of
specialties of the Republic of Uzbekistan" under the code "Classification and certification of
goods on the basis of chemical composition" 02.00.22. In 2017, the Honored Inventor of
