ABSTRACT 

The observations gave the following results, it is known that the number of seedlings per unit area is more or less, the 

number of ribbons in the tape and the distance between plants in the tape is short (5 cm) or wide (10 cm) caused the 

error amount to vary. The reason for the decrease in productivity from the small feeding area to the large feeding area 

was directly related to the number of plants per unit area. If onion sprouts are planted in a two- and three-row tape 

method, the amount of onion heads in the crop is 92,1% to 93,8%; It was found to be in the range of 86,4 percent to 

89,9 percent. Among the studied planting schemes, the highest and highest-quality yield per hectare was obtained 

from options planted in three rows, the distance between strips was 15 cm, and seedlings were planted in the strip at 

a distance of 5 and 7,5 cm (44,8; 38,7 t/ha).

INTRODUCTION 

In terms of cultivated area and gross yield, onion ranks 

second after tomato as one of the main vegetables 

grown in our republic. Not only the people of the 

republic and the processing enterprise are provided 

with the onion harvest, but also a part of its products 

is exported. One of the important resources for 

increasing the gross yield of onion is to grow onion 

seedlings as a repeated crop on the land freed from 

spiky crops and fairy vegetables.

The purpose of the experiment is to determine the 

optimal planting area and feeding area when growing 

onion from seedlings as a repeated crop, save seed 

consumption by 2-3 times and water consumption by 1-

1,5 times, and get twice the harvest from the same land 

during the season. 

Research work was carried out in the months of June-

October 2015-2016 in the area of the scientific 

educational experimental station of TashSAU. 

n the experiment, the onion variety "Istiqbol" was 

planted based on the current methodical manuals, 

each planting scheme was 3 meters long in 9 different 

schemes: (  (50+20)/2×5;  (50+20)/2×  7,5 ;  (50+20)/2×10;   

(40+15+15)/3×5;  (40+15+15)/3×7,5;(40+15+15)/3×10;   

(40+10+10+10)/4×5;  (40+10+10+10)/4×7,5;   

(40+10+10+10)/4×10) in 2 rows with 20, 15, 10 cm 

between the ribbons on the ribbon, 5 between the 

plants on the ribbon; 7,5 and 10 cm were planted. The 

experiment had 4 replications, the plants to be 

considered were placed in a plot of 4,2 m2 in each 

replication. The number of plants in the strip varied 

from 60 to 120 according to the planting scheme. 

Onion seedlings were planted in a small area (40 m2) 

from the edge of the planting area in the second 

decade of March in a scheme of 4x1 cm, and 50-55-day-

old seedlings were planted in their permanent place in 

the first decade of June according to the schemes 

indicated above. 

According to these planting schemes, the number of 

seedlings per hectare ranged from 285,7 to 1142,8. 

Phenological, biometric and other observations were 

carried out on the experimental site according to the 

approved plan (since this issue has not been studied 

before, the average of all parameters of the planting 

schemes was used as a control). 

The observations gave the following results, it was 

found that the number of seedlings per unit area was 

more or less, and the number of ribbons in the tape and 

the distance between the plants in the tape was short 

(5 cm) or wide (10 cm) caused the amount of error to 

vary. In the first variant of the experiment, when the 

spacing between the ribbons was 20 cm and the 

distance between the seedlings in the ribbon was 5 cm, 

the error rate was 6,8 percent after 10 days after 

planting, and in the variants planted with a distance of 

7,5 and 10 cm, it was 6 and 5,2 percent. In the three-row 

tape method, the error rate was found to be 6,1 out of 

8,7 percent when the distance between the tapes was 

10 cm and 5 cm, 7,5 and 10 cm were left between the 

seedlings in the tape. It was found that when onion 

seedlings are planted in a 4-row ribbon method, the 

error rate is 10,9% to 8,8%. It was found that increasing 

or decreasing the number of ribbons in the ribbon and 

increasing the distance between plants in the ribbon 

from 5 cm to 10 cm have different effects on the 

viability of onion plants. That is, if onion seedlings were 

planted in a feeding area of 0,0175 m2, 22,4 percent of 

the seedlings died during the growing period (before 

the leaves turn yellow), or 6,8 percent of the plants did 

not take root after 10 days of planting. It was found 

that it increased by 15,6 percent. During this period, the 

number of dead seedlings was 128000 per hectare. In 

this option, when the distance between the plants on 

the tape was increased to 7,5 and 10 cm, it was found 

that the amount of error was reduced by 2,3 and 6,5 

percent compared to planting at a distance of 5 cm. 

This pattern was maintained in subsequent cropping 

schemes. As the feeding areas of onion seedlings 

changed from large (0,0175 m2) to small (0,00875 m2), 

the period of entering the stage of yellowing of the 

leaves of onion plants was accelerated to a certain 

extent. That is, it was found out that the leaves of 

onion seedlings planted in 0,0175 m2 of nutrition area 

start to turn yellow after 108 days, and those planted

in 0,035 m2 of nutrition area begin to turn yellow after 

114 days. In the experiment, the yellowing of the leaves 

of seedlings planted in a three-row tape method was 

observed on days 106-115 according to the change of 

the distance between the plants in the tapes (5...10 

cm). It was found that this indicator occurs on days 

96..101 in seedlings sown in a four-row tape method. 

Planting scheme and feeding area had an effect on the 

number, length and yield of true leaves formed on each 

bush, as well as on the quality of the crop (table - 1). 

From the figures presented in Table 1, it is known that 

among the tested planting schemes, in almost all of 

them, the number of plant leaves is large and relatively 

long in the variants planted leaving 7,5 and 10 cm 

between the plants in the ribbon. The average number 

of leaves per bush of onion seedlings planted in a two-

row tape method is 1,4 and 1,2 when planted at a 

distance of 7,5 and 10 cm, and 0.7...1,4 in three rows, 

compared to when seedlings in a tape are planted at a 

distance of 5 cm. it was determined that there is a lot 

of yield per grain. In the variant of the experiment 

planted in a four-row tape method, the number of 

leaves of seedlings was significantly less (7.9...8.1 

pieces) according to the distance between the 

seedlings in the tape. Planting pattern also affected the 

length of leaves produced per plant. In the tested 

planting schemes, the length of the leaves of the 

variant plants planted in four rows (regardless of 

whether the distance between plants in the strip was 

large or small) was significantly shorter than the length 

of the leaves of seedlings planted in two and three 

rows. The number of leaves produced in each bush, 

their length and the large or small size of the feeding 

area also affected the onion yield and flour quality. 

31,5 t/ha when planted in a 0,0175 m2 feeding area in a 

two-layer tape method, 5 cm between plants in the 

tape, 1,7 and 7,7 t/ha higher yield than when planted 

with 7,5 and 10 cm distance between seedlings it was 

found that the yield was 2,1 t/ha less than the control. 

Even when planting in a three- and four-row tape 

method, the law of planting in a two-row tape method 

was preserved in terms of productivity. That is, when 

the distance between the plants in the tape was 

increased from 5 cm to 10 cm, and the feeding area was 

increased from 0,01166 m2  to 0,0233 m2, it was found 

that the yield decreased from 44,8 t/ha to 31,7 t/ha. 

The reason for the decrease in productivity from the 

small feeding area to the large feeding area was 

directly related to the number of plants per unit area. 

If onion sprouts are planted in a two- and three-row 

tape method, the amount of onion heads in the crop is 

92,1% to 93,8%; It was found to be in the range of 86,4 

percent to 89,9 percent. The average weight of onion 

heads was 71.0...90.0 g in the first three variants of the 

experiment, and 69,0...91,0 g in the second three 

variants. 

The productivity of the four-row planting scheme 

ranged from 41,5 t/ha to 29,4 t/ha depending on the 

area of seedling nutrition (0,00875...0,0175 m2). 

However, the yield did not exceed 86,8 percent, and 

the average weight of onion heads was found to be 

between 54,0 and 69,0 g. 

Among the studied planting schemes, the highest and 

quality crop per hectare is three rows, the distance 

between the strips is 15 cm, and the number of 

seedlings in the strip is 5; (44.8; 38,7 t/ha) were 

obtained from variants planted at a spacing of 7,5 cm. 

The average weight of the onion heads in the harvest 

of these options is 72; It was in the range of 81 gr. 

Conclusion. So, when growing Istikbol varieties of 

onion as a repeated crop from seedlings 

(40+15+15)/3×5 cm and the distance between plants in
