CUTTING- EDGE SCIENCE
In the simple production method in the experiment - after leveling 3 times, the result
was 63.5% of the amount of soil particles with dimensions of 10 - 0.25 mm, which is
the agronomic fraction necessary for good growth of plants, when working with KFG
- 3.6 76.9% of soil particles with dimensions of 10-0.25 mm were obtained and 83.2%
of soil with agronomic fraction required for good growth of plants when working with
milling deep softener -KFG - 3.6 to the required density with a roller 10 - The
amount of soil particles of 0.25 mm was obtained.
In the third experiment, in the control variant without mulch, the average cotton
yield was 23.6 t/ha. In the second variant, covered with a norm of 1 ton / ha of fertilized
mulch, the average cotton yield was 25.3 t/ha. The amount of additional yield obtained
was +1.7 t/ha compared to the first option. The average cotton yield obtained by the third
method, covered by the norm of 1.5 ton / ha of mulch, was 25.6 t/ha. The amount of
additional yield obtained was +2.0 t/ha from the first method.
The average cotton yield obtained by the fourth method, covered by the mulch norm
of 2 t/ha, was 26.2 t/ha. The additional yield obtained was +2.6 t/ha.
Conclusions
In the first experiment with laser equi pment 12.5 t/ha compared to the control
variant, in the second variant using KFG 3.6 equi pment 5.2 t/ha compared to the
cotton control variant, in the experiment with mulch norms the option was optimal The
average yield of cotton was 26.0 t/ha, and the additional yield was +2.6 t/ha. In
summary, when the top row of semi-rotten black cow dung was covered with mulch,
the additional yield obtained by the options was + 2.6 t/ha.
In the experiment in which different rotation systems were studied, cotton was
planted alternately with three-year alfalfa, three-year alfalfa at the rate of 100 kg / ha
per hectare in the last year, 150 kg / ha in the second year, 200 kg / ha in the third year,
and 250 kg / ha in the fourth and artificial years. , phosphorus - 175, potassium - I25
kg / ha and once every three years at the rate of 40 t / ha of local fertilizer - a method
of semi-rotten cattle, which was the best way to increase crop yields and soil fertility
while maintaining.
Taking into account the results of recent experiments on water scarcity in
Karakalpakstan, in the years when the water supply in the Republic was 40-50%,
planting of sunflower, sunflower, oats, millet, sesame and soybeans, cotton, corn,
autumn and spring wheat, millet, sesame, oily sunflower, sunflower, sorghum, cotton,
winter wheat, spring wheat, rapeseed, alfalfa and soybean crops can be sown in all
districts of the Republic when the water supply is 50-60%. When the water supply in the
country was 60-70%, high yields were obtained from millet, sesame, sunflower, sunflower,
white oats, rapeseed, cotton, alfalfa and soybeans.
Experiments have shown that it is possible to plant all agricultural crops, including
rice, in certain areas when the water supply exceeds 70%.
