ABSTRACT 

In this article, the effect of foliar feeding of potassium fertilizer on the background of mineral fertilizers on the number 

of stems and the level of preservation of hemp variety “Uzbek-2268” has been proven. Against the background of 

mineral fertilizers in the experiment, potassium mineral fertilizer was applied to the level of preservation of the 

number of stems at the end of the vegetation period in the variant given at 48 kg/ha in the phases of 2-3 true leaves 

of the hemp plant, budding-flowering and flowering-fruiting, it was found that it was 171.2 thousand bushes/ha, 

showing a high result compared to the options.

INTRODUCTION

Hemp (Hemp) is an annual plant, fibrous crop 

belonging to the Malvaceae family, Hibiscus 

Cannabinus genus and species. Hemp is found wild in 

South Africa. Homeland is India and South Africa. 

Hemp is mostly grown in countries such as India, Iran, 

China, EU and Africa. In 1915-1916, hemp was planted as 

an experiment at the North Caucasus and Turkestan 

variety testing station. It has been cultivated in 

Uzbekistan since 1927. But nowadays it is planted in 

very few areas (about 10 ha) [2]. Hemp stalks produce 

17-18% weaveable fiber. Hemp fiber is colorless, clear, 

but coarse. This fiber is used to make sacks, ropes, 

tarpaulins, home furnishings, twine and other items. 

Hemp seeds contain 18-20% oil. It is used in the oil, 

varnish and paint industry, and in the preparation of 

soap. Used as lamp oil in India. Hemp is found wild in

South Africa. Its homeland is India and South Africa. 

Hemp is mostly grown in India, Iran, China, Java and 

Sumatra islands, Africa, America (USA, Brazil, Cuba, 

etc.). In 1915-1916, hemp was planted as an experiment 

at the North Caucasus and Turkestan experimental 

station. It has been cultivated in Uzbekistan since 1927. 

Currently, hemp is grown in Uzbekistan (on a very small 

area), Kyrgyzstan, and the North Caucasus. On 

average, hemp gives 100-120 cm of stems and 4-5 cm of 

seeds from one hectare of land. But as a result of using 

high agrotechnics, 150-180 cm of green mass, 8-9 cm of 

seeds can be obtained from hemp [1; 368-370-p], [4; 

368-370-p]. 

When harvesting 100 s of stalks per hectare, 120-150 kg 

of nitrogen, 60-80 kg of phosphorus, 120-160 kg of 

potassium are taken from the soil during the growing 

season. Therefore, along with mineral fertilizers, 

organic fertilizers should be applied to the hemp crop. 

Organic fertilizer should be applied at the rate of 10-15 

tons per hectare during autumn plowing. Fertilizer 

application rate varies depending on soil fertility and 

planned yield. On average, 90-150 kg of nitrogen, 90-

150 kg of phosphorus and 50-70 kg of potassium 

fertilizers should be given to the hemp crop [3; 370-371-

p]. 

According to A.Idowu and other scientists, in recent 

years in the United States of America, experiments to 

evaluate the effect of hemp on the production of 

cannabinoids have been conducted in greenhouses. 

While hemp grown for fiber and seed has optimal 

fertilization requirements, hemp grown for 

cannabinoids requires more nitrogen fertilization to 

achieve maximum yield. From the established 

equations, the optimal nitrogen application 

recommendation required for maximum CBD yield was 

between 130 kg/ha and 250 kg/ha. These results can be 

applied to field cultivation of CBD hemp for similar 

fertilizers and cultivars, although results may vary by 

location [5; 1-10-p], [6; 363-367-p], [7; 26-29-p], [8; 517-

524-p]. 

METHODS 

It was held in the fields of experimental scientific 

research and educational experimental farm of 

Tashkent State Agrarian University. The soil of the 

experimental field is a typical gray soil that has been 

irrigated since ancient times. These soils are 

compacted according to their agrophysical properties, 

the volume weight is 1.22-1.38 g/cm3, the specific 

gravity in the arable layer is 2.59-2.61 g/cm3, in the 

lower layers it is 2.67- 2.72 g/cm3, soil porosity is 40-

46%. Depending on the mechanical composition, the 

arable humus layer (0-25 cm) is medium sand, the 

mechanical composition of the soil in the sub-arable 

layer (25-50 cm) and lower layers (50-100 cm) becomes 

heavier, heavy sand and light It consists of loamy soil, 

with a lot of heavy fractional minerals up to 2-10%, rich 

in total phosphorus and the amount of 0.15-0.30%, high 

total potassium content of 2.1-3.0%, physical clay 

amount is 47-52%. 

In 2023, in our preliminary experiments, the effect of 

potassium fertilizers on the growth, development and 

productivity of hemp plants was studied. "Uzbek-

2268" variety of hemp was taken for the experiment. 

In this case, the variety was planted on April 21, in 1 

scheme, that is, in schemes of 70 cm between rows. 

The number of options is 6, the number of returns is 4, 

the number of patches is 24. The surface of each plot 

was 28 m2, the calculated area was 14 m2, and the 

number of calculated plants was 20. 

RESULTS AND DISCUSSION 

It affects the plant's supply of light, food and water. 

The growth and development of crops, as well as the

formation of the crop, are inextricably linked to the 

number of plants. As a result of the research carried 

out in 2023, the number of bushes planted in the 

control without fertilizers at the beginning of the 

application period amounted to 158 thousand 

pieces/ha and made 79.10%. The number of plants 

planted in the background variant was 168,000/piece, 

which was 84,0%. Against the background of mineral 

fertilizers, the number of plant stems was 168.6-171.2 

thousand pieces/ha in the variants fed with potassium 

fertilizer in different rates. 

At the end of the implementation period, the number 

of bushes in the control option was 150.3 thousand 

bushes/ha and reached 95%. The results of the basic 

number of fertilizers were 97.8% and had an indicator 

of 164.3 thousand bushes/ha. The indicators of foliar 

application against the background of mineral 

fertilizers were 98.4% with 165.9 thousand bushes/ha, 

98.8% with 167.8 thousand bushes/ha, 168.5 thousand 

bushes/ha 99,0% and 169,800 bushes number showed 

99,2% results.

per ha in the option with 48 kg of potassium fertilizer 

in the background, potassium mineral fertilizer in the 

background of mineral fertilizers It increased by 12,200 

bushes/ha in the case of 60 kg/ha of iron, and 11,800 

bushes/ha when 75 kg/ha of potassium fertilizer was 

applied as a leaf foliar. Against the background of 

mineral fertilizers, the ratio of foliar application to the 

background variant increased by 0.6 thousand 

bushes/ha, 3.2 thousand bushes/ha, 12.2 thousand 

bushes/ha and 11.8 thousand bushes/ha. 

The control indicators at the end of the application 

period were 14,000 pieces compared to the control 

without fertilizer. 15.6 thousand bushes/ha when fed 

with 36 kg/ha of leaves with potash fertilizer in 

comparison to the no-fertilizer option, and 19.5 

thousand bushes/ha, and 18.2 thousand bushes/ha 

when 60 kg/ha of potassium mineral fertilizer is given 

to beryl together with the background, this indicator is 

75 kg/ha with the same fertilizer as a background when 

the amount of foliar was given, it increased to 17.5 

thousand pieces/ha bush. 1.6 thousand bushes/ha 

when foliar feeding with potassium mineral fertilizer in 

the amount of 36 kg/ha, 5.5 thousand bushes/ha in the 

case of 48 kg/ha of potassium fertilizer in the 

background of mineral fertilizers 4.2 thousand 

bushes/ha in the case of 60 kg/ha of potassium 

fertilizer in the background of mineral fertilizers, and 

3.5 thousand bushes/ha in the case of 75 kg/ha foliar of 

potassium mineral fertilizer in the background 

increased compared to the background. 

CONCLUSION 

So, in the background of mineral fertilizers, potassium 

mineral fertilizer is applied to the level of maintenance 

of the number of stems at the end of the application 

period in the given option of 2-3 true leaves of the 

hemp plant, in the stages of budding-flowering and 

flowering-fruiting, it was found that it was 171.2 

thousand bushes/ha, showing a high result compared 

to other options.
