INTRODUCTION
Rice is one of the oldest staple foods in many countries
around the world. Rice is a valuable cereal crop and is
the second most important food crop in the world
after wheat. Rice is nutritious and digestible quickly.
Rice contains 75.2% carbohydrates (mainly starch),
7.18% protein, 0.26% oil, 2.2% fiber, 0.5 % ash and 14 %
water and various vitamins. Rice decoction is widely
used for medicinal purposes. Diet with rice is used for
high blood pressure [2; 25-26 p].
Rice is distinguished by its high quality and fast
digestibility for the human div. It contains nutrients
necessary for the human div: protein, phosphorus
compounds and vitamins [6; 11-18 p] . Food made from
rice cooks very quickly, it is digested and completely
absorbed by the human div faster than other cereals.
The absorption coefficient of rice is the highest - 96%,
caloric content is 3594, and that of wheat is 6310 [1; 407
p].

Rice is a very demanding plant for warm temperatures,
its seeds begin to germinate at a temperature of 10-
14°C, its germination accelerates at a temperature of
14-15°C, 22-25°C is the most favorable temperature for
seed germination [5; 19-20 p]. A temperature of 20-30°
C is considered the most favorable during the growth
of lawns. But sudden changes in temperature,
especially during the flowering period, have a negative
effect on rice plants [4; 3-31 p], -
0.5°С cold is dangerous
for rice plants, the total amount of heat required for
rice to grow and get a high yield should be from 22000C
to 32000C and changes at this temperature [3; 3-31 p].
METHODS AND MATERIALS
The agrotechnical activities in the experimental area
were carried out based on RRI's "Recommendations
on the technology of growing rice by seedling method
in the conditions of Uzbekistan" (2010).
In research, phenological observations were carried
out in the method of "Field experiment methods" to
determine biometric indicators in all returns and
variants of field experiments.
The experiments were carried out in 6 options, 4
repetitions, each option is 100 m2 in a total area of 24
00 m 2, total protection area and corridors are 260 0
m2, options and returns are placed in an orderly
manner.
The experimental plots were planted by hand and were
prepared according to the recommended technology,
in which the field was covered with water in a layer of
1-3 cm before planting.
Determining the economic efficiency of the
experimental options, the costs spent on crop
cultivation, the obtained net profit and other economic
indicators with the average value of 2022-2023 in the
V.N.Polojiy method, the statistical analysis of the
results obtained from the experiments were calculated
based on the B.A.Dospehov method using the
Microsoft Excel program. In this case, based on the
expenses incurred and the income received according
to the options, the average standard prices accepted
by Tashkent Region Cereal Products JSC were used.
RESULTS AND DISCUSSION
J.Uddin, S.Ahmed, O.R.Harun, M.Hasan, Asaduzzaman
in 2011 planted the rice plant in three different planting
schemes and studied some of its biometric
characteristics that form the basis of the crop,
including the effect of furrow length on productivity.
have learned As a result, it was observed that the
furrow length was 26.8 cm in seedlings planted in a
20x20 cm planting pattern. It was determined that 26.4
cm was found in the seedlings planted in the 25x20 cm
planting scheme and 22.4 cm in the seedlings planted
in the 20x10 cm planting scheme.
It is known from Matsumoto's experiments in 2017 that
as the thickness of the seedling increases, the length of
the furrows becomes shorter and the number and
weight of whole grains in the furrow decreases.
Like Bhuneshwar Verma, L.K.Ramteke, M.Shahid In
2019, scientists planted rice seedlings in 15x10, 15x20
planting schemes and conducted scientific research. As
a result, in the 15x10 planting scheme, compared to the
15x20 planting scheme, the elements of the crop, that
is, the number of productive stems is 4-5 pieces, the
length of the furrow is 2-3 cm, the number of grains in
the furrow is 5-7 pieces, and they noted that the weight
of 1000 pieces of grain was up to 0.7-1.3 grams.

that determine the productivity of a rice plant is its
biometric indicators. Because, he stated that
productivity is determined by parameters such as the
length of the furrow, the number of whole grains in the
furrow, the weight of 9990 grains. (2002)
Z.N.Djumanov,
S.Sh.Makhmudova
and
A.Egamnazarov.
In the laboratory experiments conducted by
A.P.Egamnazarov and others in Khorezm in 2002, in the
rice plants grown directly from seeds as the main crop,
during the growing season, 208 fruitful stalks and 208
fertile stalks were produced in 1 m2 of the area, the
level of establishment was 1 o in the plant was equal to
2.08, and the number of fruitful stems in 1 m2 of the
plant planted as seedlings was 260 such stems and
buds, that is, the level of germination in 1 plant 2.60
equal to more than 52 panicles were received.
In 1962, Ch.Mamedov planted 3, 6, 9 seedlings in each
nest in the soil and climate conditions of Azerbaijan in
10x10 cm, 20x20 cm and 30x30 cm images, and as a
result of his research, when he planted 6 seedlings in
each nest in the 10x10 cm image achieved the highest
yield. Because in his opinion, when rice seedlings are
planted thickly, the number of whole grains in the
furrow decreases to 6-7 pieces, but as a result of the
increase in the number of plants per unit area, the total
productivity increases by 15-22 s/ emphasized.

In the experiment, samples were taken to analyze the
biometric indicators of the rice plant, the biometric
indicators of the yield elements of the rice varieties
were determined, and the following results were
obtained:
30 days seedlings of the "Iskander" variety in the third
decade of May, 333 thousand pieces/ha, i.e., in the first
option planted as seedlings in the 30x10x1 scheme,
during the ripening period, the total number of stems
per 1 m2 was 218.3 pieces, the productive stems were
198.5 pieces reached, the length of one pod was 18.7
cm, the number of grains in the pod is 140, the weight
of one pod was 3.9 grams, the number of whole grains
was 106.6, the number of empty grains was 33.4 it was
observed that the weight of 1000 grains was 32.9
grams.
CONCLUSION
Summary by doing that's it to say maybe rice Iskandar
and Ilgor varieties in the scheme 30x10x1 when planted
that biometric indicator of rice was observed well.
