INTRODUCTION 

The soils of the Bukhara oasis are mainly meadow 

alluvial and formed on the basis of the sediments of the 

Zarafshan river flowing through the water for 

thousands of years.  The climate is a sharply changing 

continental climate.  The history of farming goes back 

several thousand years.  Irrigation farming is mainly 

developed in Bukhara.  Since the soils of Bukhara are of 

different degrees of salinity, agrotechnical activities of 

salt washing are carried out in these lands in the 

autumn and winter season, and this event also leads to 

a decrease in soil fertility. A number of scientists F. 

Jumaev, N. Safarova 2018y, F. Jumaev, Yu. Hikmatova  

2019, F. Jumaev, Z. Ataeva 2021.  (1-3) have scientifically 

studied how to increase soil fertility by planting 

leguminous crops. 

Irrigated agriculture is developed in the Bukhara 

region, and the land areas where all agricultural crops 

are grown are made up of soils with varying degrees of 

salinity.  Therefore, effective use of land, selection of 

exportable crops suitable for these soil conditions, and 

increasing soil fertility is one of the urgent tasks of 

today.

Picture-1.  Soy and cotton varieties 

Soybean plant with leguminous, oily, protein-rich is of 

great importance in agriculture, effective use of land 

with low quality and productivity, ensuring national 

economy and food security, increasing land 

productivity and achieving economic profitability. 

Method of the experiment: The experiments were 

conducted at the training-field experimental farm of 

the Faculty of Agronomy and Biotechnology of the 

Bukhara State University and at the "Arbob Botir" farm 

in the Bukhara district.  done.  Genetic-1, Orzu and 

cotton Bukhara-6 varieties of soybeans were used in 

the experiment (picture-1). 

Experimental results: Soy belongs to the genus Glycine 

L., which is divided into two subspecies.  The first is the 

subgenus Glycine Wild, which includes 9 species, and 

the second is Soja (Moench) F.Y.NERM.  2 species 

belong to the subfamily, according to R. G. Palmer (4), 

there are 11 species in total.  When the polyploid level 

of soybean was studied (haploid n-20), it was found 

that there are mainly diploid (2n=40) and two 

tetraploid (2n=80) species (5). 

 Soja (Moench) F.Y.NERM.  There are 2 species in the 

subfamily, the diploid (2n-40) G. soja Sieb and the 

cultured G. max L. Meer.  According to V. B. Enken (6), 

the cultured soybean type G. max L. Meer is divided 

into 6, i.e., semi-cultured, Indian, Chinese, Korean, 

Manchurian and Slavic subtypes. 

In the world, N.I.  Vavilov (7) identified two centers of 

origin for the soybean plant, i.e., the center of 

Australia, although the center of soybean is more 

ancient, Southeast Asia.  Although central Australia is 

more ancient, soybeans have been cultivated by 

humans in Southeast Asia.  The United States is the 

largest soybean-growing region in the world.  These

cultivated areas are 35.6 million hectares in the USA, 

33.3 million hectares in Brazil, 11 million hectares in 

China, and 3 million hectares in Japan.  It is also 

cultivated in many countries such as Russia, India, 

Korea, Vietnam, Indonesia, European countries, North 

Africa, Australia (8). 

Soybean production in the world is 320.5 mln.  tons, of 

which Brazil has 106.6 mln.  tons, the USA currently has 

106.1 million.  tons, Argentina 58.5 mln.  produces tons.  

Brazil is the leading country in the sale of soybean grain 

and meal, or 57.6 mln.  tons of soybeans and 15.6 

million tons of wheat flour.  The main purchasing 

country is China (8). 

The soybean plant is heat demanding.  A temperature 

of 12-14ºС is recommended for seed germination and 

18-20º for grass formation.  The temperature of 1600-

1700ºС is necessary for the earliest varieties of soybean, 

200-2200º for middle-ripening varieties, and 2800-

3000ºС for late-ripening varieties.  4-5 kg of nitrogen, 

2.3-2.5 kg of phosphorus and 3.5-3.7 kg of potassium 

are used to obtain one centner of soybeans.  Soybean 

grows and yields well in all saline soils in Uzbekistan. 

 "Orzu", "Nafis", "Genetic-1" in the early part of the 

republic, "Dostlik", "To'maris", "Oyjamol", 

"Uzbekskaya-2", "Parvoz" and "Baraka", "Uzbekskaya-

6"  ” late ripening varieties were created.  Early 

varieties ripen in 75-90 days, medium-ripening varieties 

in 100-120 days, and late-ripening varieties in 135-140 

days.  The productivity of soybeans is very dependent 

on the varieties.  (9). 

To increase livestock productivity, when animals are 

fed soybean meal, their daily weight gain doubles.  In 

order to reach 100 kg of live weight, the feeding period 

is shortened by 10-15 days, and the quality of the 

product increases.  For fodder, soybean meal, flour, 

and greens are used.  Kunjara contains 38.7% protein 

and 5.5% oil.  Soybean meal and meal replaces milk in 

calf rations.  1t.  750-800 kg of meal can be obtained 

from soybean meal when it contains 40% protein and 

1.4% oil.  It is observed when it is harvested during 

flowering and grain maturity, which is valuable for 

livestock.  145-301 grams of protein per serving of 

soybean greens. 

Soybean is a valuable plant that is of great importance 

in the food industry, medicine, and especially in 

agriculture to improve soil fertility.  Soybean seeds 

leave behind 85-95 kg of ecologically pure biological 

nitrogen on one hectare of land when they are not 

treated with nitrogen bacteria.  This ensures rapid 

growth and high yield of the next planted agricultural 

plants. 

When obtaining a high yield from agricultural crops, 

soil fertility undergoes important biological processes, 

and with the participation of microorganisms, complex 

organic substances turn into active substances 

absorbed by plants.  The amount of microorganisms in 

the soil, their activity depends on the mechanical 

composition of the soil, its density, the amount of 

humus, the level of humidity and other factors. 

According to the decision of the President of the 

Republic of Uzbekistan dated December 29, 2015 No. 

PQ-2460, during the period 2016-2020, 10 thousand 

hectares of cotton yielding 12-15 centners of cotton and 

5 thousand hectares of grain fields yielding 15-20 

centners of cotton in the period 2016-2020, a total of 15 

thousand hectares of low productivity  areas have 

been reduced, and in order to effectively use these 

areas and increase their productivity, to improve the 

soil structure, it has been decided to establish 

vegetable, oil leguminous crops and intensive 

vineyards.  Based on this decision, the selection and 

planting of leguminous soybean varieties suitable for 

the conditions of Bukhara in the fields of farms in the

Bukhara region, and its effect on the effective use of 

land, soil fertility and the yield of subsequent crops 

were studied. 

In the educational and practical field of the Bukhara 

State University, a comparative analysis was made of 

the grain yield of the soybean variety "Genetic-1" 

planted in April and as a repeat crop after the autumn 

spiked grain in July, and the yield of the cotton variety 

Bukhara-6 planted the following year in the fields 

planted and not planted with soybeans.  In addition, 

the productivity of soybean variety "Orzu" will be 

analyzed at "Arbob Batir" farm in Bukhara district.  The 

data obtained on the basis of experiments show that 

when the "Genetic-1" variety of soybeans was planted 

on April 12, it fully ripened by August 20, and on 

average, in 2012-2015, 32.1 centners of grain was 

obtained per hectare, and when it was planted after 

repeated sowing, a harvest of 24.5 centners was 

achieved.  After soybeans, an average yield of 36.8 t/ha 

was obtained from the area planted with Bukhoro-6 

variety, while an average yield of 31.7 t/ha was obtained 

from the area without soybeans.  Also, on average, 

29.5 t/ha of soybeans were planted on 1.5 hectares of 

"Arbob Botir" farm.  In the following year, 35.6 t/ha of 

raw cotton was obtained from cotton in this area, and 

the yield in the contour next to soybeans was 31.2 

quintals. 

CONCLUSION 

As a result of scientific research, it is possible to 

conclude based on the data obtained from the 

experimental field of Bukh.DU and from the farm fields 

and recommend to farmers that in the conditions of 

Bukhara region, for effective and productive use of 

land, to increase soil fertility and to obtain a high yield 

from cotton, the main and early varieties of 

leguminous soybean should be used.  planting as a 

repeated crop is of great importance, which provides 

an average additional yield of 4-6 centners per hectare.
