Definition of technology:
Technology offers the combined cultivation of technical crop - cotton and food crop - mung bean using resource-saving technologies of soil processing.
Brief summary of technology:
The combination of cotton and mung bean cultivation was made possible by a new seeding-machine of the Dasmesh company that performs several agricultural activities in one pass: forms ridges, furrows, plants seeds into loosened soil and applies fertilizers. This agro-method allowed to harvest 2 crops - cotton and mung bean. Mung bean enriches the soil with nitrogen, contributing to the maintenance of soil fertility and biological activity.
The experiment provided the elimination of inter-row processing and reduction of evaporation from soil by mulching irrigation furrows with dark perforated polyethylene film.
Cost-effectiveness of combined "raised bed planting of cotton and with mung bean + mulching" is higher compared to only cotton planting: - under the row spacing of 90 cm above the profitability is higher by 90.9%, and under 60 cm row spacing - by 71.7%.
Location: “Esanbay ota” farm, Pakhtakor district, Jizzakh Province.
Area of technology application: 30 ha.
Stage of intervention: mitigation / reduction of land degradation.
Main land use issues and the main causes of land degradation:
Farmers use outdated cultivation methods, lack of modern agricultural machinery and equipment leads to low productive capacity of the land.
Main technical features of technology:
Reduction soil tillage times, irrigation water saving, improvement of soil properties and increase of the profitability of crop production.
Type of land use Conservation measures
Production of annual crops - Во(Са).
А2: Organic matter / soil fertility;
A3: Topsoil processing.
Habitat Anthropogenic environment
Average annual rainfall: 200-400 mm.
Altitude (meter above sea level): 100-350 m.
Slope (%): 0-2% (flat); 2-5% (steep).
Soil fertility: low.
Humus content in arable horizon: <1%.
Size of land area (ha): 30-55 ha.
Landholder: farmer and dehkhan households.

Water use rights: through WUAs and organizations responsible for management of irrigation systems.
Natural soil drainage/infiltration: low.
Market orientation: subsistence farming (selfsufficiency), free market.
Impact of technology
- obtaining two crop yields from one area;
- high profitability;
- possibility to improve soil in the absence of crop rotation.
- high cost of a seeder;
- the need for polyethylene film and of its recycling;
- there is no experience in a combined cultivation of various crops.
