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 body. It contains nutrients 

necessary for the human body: 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 body 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.
