Increasing the efficiency of growing cotton with water-saving irrigation technologies


SDG Agenda 2030


Within the framework of the project "Renewable energy sources for efficient use of energy resources and sustainable management of Turkmenistan's water economy" of the UNDP/GEF and Turkmenistan's State Committee for Water Management, demonstration irrigation areas of the 145 ha research area of ​​the "Turkmensuwylymtaslama" institute were developed using drip irrigation, artificial rain and portable irrigation. It is equipped with a modern water-saving system of irrigation of agricultural crops such as improved surface irrigation using irrigation hoses. Studies have been conducted on these irrigation systems to study the effectiveness of growing cotton, winter wheat, vegetables, and forage crops with various water-saving irrigation methods.

Here, since 2018, scientists and graduate students of the "Turkmensuwylymtaslama" Institute and the Turkmen Agricultural University have been conducting experimental research in the field of irrigated agriculture.

The scientific research conducted by young scientists and graduate students allowed not only to prepare monographs or scientific works, but also to solve the following problems in the field of irrigated agriculture:

  • The economic efficiency of growing crops with different irrigation methods (drip irrigation, artificial rain and surface irrigation) was determined;
  • A new standard of rules for various crop cultivation technologies and irrigation methods (drip irrigation, artificial rain and sprinkler irrigation) was prepared;
  • The effect of different technologies on the cultivation of agricultural crops and irrigation methods on soil fertility and salinity, as well as on the formation of drainage water was determined.
  • Energy consumption and atmospheric CO2 emissions for different technologies of agricultural crop cultivation and irrigation methods were determined.


In 2018-2021, with my participation, scientific work was carried out on the dissertation topic "Increasing the efficiency of growing cotton with water-saving irrigation technologies".

According to the obtained data, the amount of yield in the drip irrigation system is significantly higher compared to other methods, more precisely, the yield in the option with 80-85% soil boundary stability is in the range of 6.25...6.67 t/ha, which is 0.90...1.21 t/ha or 16.8...22.0% more compared to the other options of drip irrigation, in comparison with other studied irrigation methods, this indicator was improved by 3.0...2.57 t/ha and 0.80...2.39 t/ha or 64...92%, respectively, in the corresponding options of artificial rainfall, it can be seen that in our standard method it is 3.29...3.07 t/ha or 91% more.

Based on the data of this dissertation, 2 scientific articles were published. The scientific-practical information about growing cotton was also described in the monographs: "Guide to designing drip irrigation systems of agricultural crops, vines, orchards, forest trees in the soil-climate conditions of Turkmenistan" (2020), "Guide to the Design and Use of Artificial Rainfall Irrigation Systems For agricultural crops in the soil-climate conditions of Turkmenistan" (2021).
