Definition of technology:
Crop planting in ridges is carried out by a special seeder, which simultaneously forms ridges, plants along and between the ridges, makes furrows for irrigation, stimulating a reduction in irrigation erosion and reduction of irrigation water use.
Brief summary of technology:
Ridge planting technology is applied in the CIS countries (Kazakhstan, Kyrgyzstan, Azerbaijan, Tajikistan etc.) for the cultivation of cereals, legumes, vegetables, technical and oilseed crops.
Ridge sowing of the grain crops can be done on almost all gray soils, gray-brown soils with medium and light texture. Width between ridges is 60-70 cm.
It is possible to sow 2-3 rows of crops with a distance of 15 cm on the ridge. The seed rate of grain crops is 100-150 kg/ha instead of 200-250 kg/ha with traditional method of seeding. Raised bed planting technology creates an optimal water-air and thermal regimes for agricultural crops, provides high efficiency of furrow irrigation, water saving by 25-30% and increase of the yield of winter wheat from 5 to 8.3 t/ha. To implement this technology in Kyrgyzstan, a SBP - 2.8 seeder made in Turkey has been used, which allows forming ridges, planting seeds and at the same time forming furrows for irrigation between ridges. Bed planting technology was tested in the Chuy Valley within the frame of the ICARDA project on "Sustainable Land Management", where an Indian «Deshmesh» seeder was used.
Location: Sokuluk and Kant districts, Chuy province.
Area of technology application: 10 ha.
Stage of intervention: reduction of land degradation.
Main land use issues and the main causes of land degradation:
The terrain has a flat and gently sloping landscape. In this zone, there are waterlogged and saline areas. As a result of over-irrigation, irrigation water and groundwater merge, leading to soil salinization, waterlogging.
Main technical features of technology:
Improvement of surface structure, water-air and thermal regime of soils.
Type of land use Conservation measures
Irrigated arable land.
Production of annual crops - Во(Ca).
A3: Processing of the soil surface.
Habitat Anthropogenic environment
Average annual rainfall: 400-500 mm.
Altitude (meter above sea level): 500-1000 m.
Landscape: plains, valley.
Slope (%): 2-6% (moderate, plains).
Soil fertility: average.
Humus content in arable horizon: 1.5%.
Natural soil drainage/infiltration: average.
Size of land area (ha): 2-5 ha.
Landholder: small/moderate, mixed.
Land ownership: 75% of the individual and the state, 25% of arable land; state-owned pastures.
Water use rights: through WUAs and organizations responsible for management of irrigation systems on relevant payment.
Market orientation: subsistence farming (self sufficiency), free market.
Impact of technology
- promotes adaptation of crop production to climate change through the use of new highly productive crop varieties;
- creates conditions for the application of integrated plant protection methods;
- saving seeds and irrigation water.
- relatively high price for raised bed seeder for farmers;
- powerful tractors with over 100 horsepower is required for the operation of raised bed seeder;
- difficulty of combine harvester movement along the sliced furrows.
Acceptance/adoption of technology: In Kyrgyzstan, raised bed planting technology was originally implemented with the support of the «Sida» and «Support seed industry of Kyrgyzstan" projects. Further dissemination of this method has been done by the Seed Farming Association of Kyrgyzstan (SAK) under the CACILM project.
