ABSTRACT
This article provides information on the results of studying the optimal planting scheme for obtaining high and quality
yields from cucumber hybrids in an unheated greenhouse. In order to increase the yield of cucumbers and grow crops
quickly, it is necessary to ensure the optimal planting scheme of the plant. Placement scheme and number of plants
have an effect on increasing yield and improving its quality. Therefore, the study of feeding area and planting pattern
will always remain the main focus of research. Studying the relationship of planted plants to each other is a theoretical
basis for developing a feeding area and a planting scheme.

INTRODUCTION
An important element of crop cultivation is the
arrangement of plants, their feeding area and optimal
density parameters. These parameters significantly
affect temperature, air, water and nutrient regimes [2;

3]. The effectiveness of mineral nutrition increases by
providing plants with optimal moisture. The amount of
nutrient space required for cucumber plants depends
on the characteristics of the variety. An increase in the
feeding area due to the expansion of the row spacing
leads to the elongation of the stem, the number of
leaves increases, and the increase in the distance
between plants promotes the appearance of
additional shoots [1; 4]. In excessively dense plants, it
not only blocks the side branches, but also causes a
decrease in maternal flowers [2; 3; 5].
LITERATURE REVIEW
In our experiments, 4 planting schemes of Sardar F1
and Orzu F1 cucumber hybrids were studied in
unheated greenhouses: 80×30 cm, 80×40 cm, 80×50
cm (control) and 80×60 cm.
In the phenological observations of cucumber hybrids
Sardor F1 and Orzu F1, planting schemes did not affect
the appearance of sprouts. 3-4 days were enough for
the initial emergence of sprouts for the crop and 5-6
days for mass emergence.
75% opening of maternal flowers in Sardar F1 hybrid
was 45 days in standard 80x50 cm planting scheme, 47
days in 80x30 cm scheme, 46 days in 80x40 cm and 44
days in 80x60 cm planting scheme and averaged 45
days. In the Orzu F1 hybrid, the distance between
plants is 80 cm, and when the distance between plants
in a row is expanded from 30 cm to 60 cm, the opening
of maternal flowers takes 48-45 days or they decrease
from 1 day.
The coefficient of variation was small (v = 1.2%) in the
Sardar F1 hybrid with 75% opening of maternal flowers.
This is a good situation.
10% technical fruit set in Sardor F1 hybrid, as the
distance between the seedlings in the row widens, the
fruit set is accelerated. Their fruiting period was
between 55 days (80x50 cm) and 48 days (80x30 cm)
depending on the planting season. In the Sardar F1
hybrid, the average of the planting schemes was 51,5
days.
In Orzu F1 hybrid, it took 52 days for 10% of fruits to be
technical in 80×50 cm standard option, 56 days in
80×30 cm, 49 days in 80×60 cm and 80×40 cm planting
scheme information was equal to the standard option.
The average of all planting schemes was 52 days for the
Orzu F1 hybrid. The average indicator of the coefficient
of variation of fruit processing was small (V = 4,5%). This
is a good indicator.
According to the classification, the height (stem) of the
cucumber plant is short - up to 80 cm; medium - 80-150
cm, long - 150-225 cm and very long are divided into
groups longer than 225 cm. Since the varieties we
tested had a stem length of more than 225 cm, they
belonged to the very tall group.
DISCUSSION AND RESULT
The 70-day stem length of the Sardor F1 hybrid was
244,7 cm in the 80x50 cm standard variant, compared
to 282 cm in the 80x30 cm planting scheme, 253,7 cm
in the 80x40 cm, or 111,2
–
103,7% higher. When the
plants in the row are widened, the height of the plant
is slightly reduced. In the scheme of 80x60 cm, it was
228,3 cm or 90,0% compared to the standard. The
Sardor F1 hybrid averaged 252,2 cm or 103,1% of
planting plots.
Orzu F1 hybrid 70-day-old plant has a height of 235 cm
in standard version (80x50 cm), and when the distance
between plants in the row (80x30 cm and 80x40 cm) is
shortened, its stem is 290,1 cm and 253.3 cm, or 65,1-
18,3 up by cm. The plant height was reduced by 227 cm
in the 80x60 cm scheme or 96,6% according to the

standard. Orzu F1 hybrid plots averaged 251,33 cm or
107% more than the standard variant.
In a 70-day-old plant, in the Sardor F1 hybrid, the
standard version of 80x50 cm had a leaf area of 71,5
dm2. It was 94,4% compared to the standard when the
distance between the plants in the row was reduced by
10 cm, and 83,9% when it was reduced by 20 cm. When
the distance between the plants in the row was
expanded by 10 cm compared to the standard, the level
of the leaves was 73,2 dm2 or 102,4% wider than the
standard in the 80x60 cm planting scheme. In the
Sardor F1 hybrid, the average of all planting schemes
was 68,1 dm2 or 95,2 %.
In the Orzu F1 hybrid, the leaf surface area was 70,1 dm2
in the standard version of 80x50 cm, and when the
distance between plants in the row was reduced by 10
cm, the surface of the leaf surface was reduced by
95,3% compared to the standard, and by 90,2% when it
was reduced by 20 cm. When the planting scheme was
expanded by 10 cm compared to the standard, the leaf
surface area was 72,3 dm2 or 103,1% more than the
standard. In the Orzu F1 hybrid, the average indicator
of the leaf surface area of all planting schemes was 68,1
dm2 or 97,1% compared to the standard option. During
the period of technical maturity of fruits, the total fruit
weight on one bush plant was 5,6 kg in the standard
variant of 80×50 cm, and compared to it, 4,2 kg in the
planting scheme of 80×30 cm, 5,3 kg in the planting
scheme of 80×40 cm, or 75,0-94,3% in comparison with
the standard. In the 80×60 cm planting scheme, the
fruits weighed 6,3 kg or 113,2% more than standard. The
average of all planting schemes by total fruit weight is
5,2 kg, which stopped at 94,2% compared to the
standard.
In the Orzu F1 hybrid, the total fruit weight was 5,6 kg
in the standard planting scheme of 80×50 cm, and 1,6
kg in the planting scheme of 80×30 cm and 0,4 kg in the
scheme of 80x40 cm. As the row of plants (80-60 cm)
expanded, the total fruit weight increased
–
6,1 kg, or
it was 109,5% more than standard. The average of all
planting schemes was 5,1 kg and was 92,3% compared
to the standard.
CONCLUSION
The yield of the Sardor F1 hybrid was 139 t/ha in the
standard variant of 80×50 cm and a much higher 164,5
t/ha or 117,8% in the planting scheme of 80×40 cm. As
the number of plants per hectare decreased,
productivity also decreased, and in the 80×60 cm
planting scheme was 126,9 t/ha, or 91,2% compared to
the standard. The average of all planting schemes by
yield is 148,1 t/ha, or 106,1%.
The yield of the Orzu F1 hybrid was 140 t/ha in the
standard variant of 80×50 cm and a much higher 161,3
t/ha or 115,2% in the planting scheme of 80×40 cm. As
the number of plants per hectare decreased,
productivity also decreased, and in the 80×60 cm
planting scheme was 123,1 t/ha, or 87,9% compared to
the standard. The average of all planting schemes by
yield is 145,3 t/ha, or 103,8%.
