The results of the research: in the conditions of
the alluvial soils of the saline meadow of
Karakalpakstan and in the research work
conducted in the plant science laboratory of the
Institute of Agriculture and Agrotechnology of
Karakalpakstan, when phenological observations
of sorghum varieties were carried out, the rate of
sowing its seeds and It was determined that it
changed depending on the rate of fertilizers.
Planting rate and mineral fertilizer rates used in
the experiment affected the growth of Corn
varieties. Joʽhari cultivars are slow growing in
their first year of life and have been adapted to
both flowering and grain yield. Stem height 1.06;
1.07; 1.08; Measured on 1.09 dates.
When sowing Joʽhari seeds at the rate of 20 kg per
hectare and applying fertilizer at three different
rates
(N50P70K60,
N100P140K80
and
N150P200K120 kg/ha), the height of the first
year's sweet potato is 36.5-42.8 at 1.06 cm, 1.07
75.2-83.2 cm 1.08 95.2-125.5 cm 1.09 130.5-
195.2 cm.
The height of the stem is 36.5-42.8 in comparison
with the variant of the first standard of fertilizer
used in the middle standard of fertilizer; cm from
130.5-195.2; cm was found to be higher. During
the period of operation, the rate of growth of corn
does not go at the same rate. Average growth per
day when 20 kg/ha seed was planted was 0.39-
0.33 cm in the first month, 2.5-2.8 cm in the
second month and 3.17-4.2 cm in the third month
. It should be pointed out that the optimal growth
of sweet potato was observed in the first year
when the seed sowing rate was 25 kg per hectare
and mineral fertilizer was used at the rate of
N100P140K80 kg/ha. (Table 1).

The effect of sowing and mineral fertilizers on the
growth dynamics of the Corn plant, the growth of
Corn in the second year is presented in Table 2.
When fertilizers are applied to the corn plant at
the rate of N50P70K60 kg/ha in the first option,
the plant height is 56.3 cm in 1.06, 86.2 cm in 1.07,
115.6 cm in 1.08, 1.09 It was 140.5 cm. In the
second option, i.e., in the second option, where
fertilizer was applied at the rate of N100P140K80
kg/ha, the plant height was 70.4; 90.6; 130.5; It
was 210.6 cm. Fertilizer rate of N150P200K120
kg/ha, in the third option used, when it reached
1.08 months of corn, it was observed that it lays
down differently during the fertilization period. It
can be explained that the reason for this is the use
of nitrogen fertilizer at a high rate (Table 2).

In the fifth option, when growing corn, 25 kg/ha
of N100P140K80 kg/ha were fertilized, the height
of the plants measured on 1.06 was 65.6 cm, 1.07
was 110.8 cm, 1.08 was 150.6 cm and 1.09 was
230.5 cm, and it was observed that the height of
the stem was low in the remaining options. The
reason is that the thickness of the seedling is very
high, and it was observed that the plant lay down.
During the second year of operation, daily growth
is 1.94-2.18 cm in the sixth month, 3.08-3.69 cm
in the seventh month, 4.08-5.02 cm in the eighth
month, and 5.52-7 in the ninth month. It was 68
cm.
The height of the stem is 4.9 compared to the first
rate of fertilizer in the medium fertilizer rate
used; 6.3; It was found to be 4.8 cm higher.
The growth rate of sorghum during the period of
operation is not uniform. The average growth per
day when 20 kg/ha of seed is planted is 1.87-2.34
cm in the sixth month, 2.87-3.02 cm in the seventh
month, 3 in the eighth month. .85-4.35 and in the
ninth month it was 4.68-7.02 cm.
It was determined that the number of leaves and
seeds depends on the rate of mineral fertilizers,
and the number of leaves is up to 8-17 pieces (on
one stem) and the number of seeds is up to 950-
1850 grains.
The number of seeds was 1010 pieces on 1.09 in
the first option, where the standard amount of
fertilizers N50P70K60 was applied at 20 kg/ha, in
the second option it was 1310 pieces, and in the
third option it was 950 pieces. The standard
planting rate of 25 kg/ha of N100P140K80
mineral fertilizers was 1210 units in the fourth
option, 1850 units in the fifth option, and 1100
units in the sixth option. Planting norm
N150P200K120 in the amount of fertilizers norm
was 1000 units in the seventh option, 1200 units
in the eighth option and 1050 units in the ninth
option (Fig. 1).

Figure 7. Effect of planting and fertilization rates on the number of leaves and seed development
of the second-year corn
So, in the research field, the number of leaves and
seeds in the field of sorghum depending on the
norm of mineral fertilizers showed the best
performance in the 5th option with the norm of
N100P140K80 fertilizers.
In the 2nd year of the experimental field where
the research was carried out, the number of
leaves and seeds in the sorghum crop depending
on the rate of mineral fertilizers was observed on
1.09.
According to the obtained data, 25 kg/ha of
N50P70K60 fertilizers were used in the 1st
option, 10 leaves and 1210 seeds per hectare
were obtained, in the second option, when
N100P140K80 kg/ha was used, 14 leaves and
1320 seeds were obtained, N150P200K120
kg/ha. The number of harvested leaves was 12
and the number of seeds was 1250 (Fig. 2).

It was found that the number of leaves increased
to 16-17 and the number of seeds increased from
1360 to 1620.
So, in the experimental field where the research
was carried out, the number of leaves and seeds
in the field of corn between the first and second
year was significantly different than the results
obtained depending on the rate of mineral
fertilizers. The reason is that a certain amount of
NPK of the first year was preserved in the soil
composition for the next year, and thus the
productivity of the second year showed a slightly
higher performance.
Of course, comparing the yield of the first and
second year according to the options, it was found
that the level of yield increased with the addition
of 25 kg/ha of seeds and N100P140K80 of
fertilizers.
