¿En base de qué criterios o indicadores (no relacionados con la Estrategia) se ha considerado la práctica propuesta y la tecnología correspondiente como ‘óptima’?

The use of the raised-bed seeding unit immediately reduces the need for mechanized activities in the field, seeding rates and thus production expenses. Furthermore, it is an excellent platform for diversification of the common cotton-wheat systems through intercropping, relay-cropping, and mixed farming aimed at integrating crop-livestock systems. Combined with laser-assisted land leveling, the raised-bed planting system can improve the productivity of high-value crops and reduces leaching and irrigation water equipments. Distributed to the participating countries, the raised-bed planters were used for several research activities including seed management, crop diversification and zero-tillage (conservation agriculture), a sustainable agricultural practice with potential to reduce soil erosion and salinization, and increase soil fertility. |

Breve descripción y especificaciones técnicas de la tecnología

The raised-bed seeding units imported from India (Dashmesh®) in the frame of the SLMR project have the advantage that they can simultaneously seed, fertilize and shape the furrows for irrigation. The direct seeding unit allows for seeding different crops alongside, i.e. intercropping.|

Describa los impactos in situ (los dos principales impactos por categoría).

1. possibility of using the seeder together with a laser leveler reduced water use by 25-30%
2. possibility of planting into standing stubble showed potential for conservation agriculture (sustainable agricultural practices)
Socio-economic level (including cultural level):
1. production costs were reduced due to reduced mechanized activities; more than 200% net benefit increase
2. intercropping with legumes increased net benefit by 200%
1. irrigation water use reduced by 10%
2. other nature protection impact (e.g., erosion, salinization) could not be measured due to short period of the project
1.  enhanced germination up to 20%; reduced seed quantity by 40%; yield increased
2.  possible diversification of current cropping system by intercropping using legumes thus improving soil fertility, and food and feed provision

3. other impacts beyond the implementation area could not be measured due to short period of the project
1. raised interest by farmers in the proximity of the experiments
2. raised interest by researchers to continue working with the seeder

Impacto en la diversidad biológica y el cambio climático

Justifíquelo:

- raised-bed seeder can be seen as water-wise technology that increases water productivity and has the potential to decrease soil salinity
- crop productivity and farm income increased (production costs decreased); and potential for diversification of the cropping system positively tested, all of which reduces vulnerability to climate change
- possibility of planting into standing stubble/left residues has potential for reducing water-related erosion, soil evaporation and thus salinization, and increases soil fertility, thus making the system more resilient

¿Se ha elaborado un análisis costo-beneficio?

¿Se ha elaborado un análisis costo-beneficio? :

Sí

Especifique:

The most important benefit and most convincing for the national scientists and farmers was the cost reduction due to the reduction of mechanized activities from 11 to 5. Turkmenistan reported reduced production costs of winter wheat of nearly 23%, and Uzbekistan of around 12%. Consequently, the net profit could be doubled. Intercropping maize or cotton with legumes increased the net benefit by 200%.
The production of a seeder in Uzbekistan costs up to about 6.5 million UZS. Depending on the depreciation assumptions and the number of ha to be seeded it could take up to 2-4 years to cover the investments. This payback period would increase in case the entire equipment is imported since in addition to the purchase price also the relatively high transport costs would need to be recovered.

En relación con los recursos humanos

1. Support and development of extension-type structures for awareness-creation among producers and trainings
2. Encourage shift in research paradigms and agricultural thinking
3. Improve links between farmers| markets and service organizations

En relación con los aspectos financieros

1. Import and/or development of machinery suitable for raised-bed seeding and implementing conservation agriculture essential for further spreading this practice
2. micro-finance system needed for farmers to purchase new equipment
3. Investing in the raised-bed seeder could be a suitable strategy for farmers with larger farms. Smaller-scale farms could either hire the planter from neighbors or group together. Alternatively| the MTP| WUA or extension services could rent such equipment to farmers

En relación con los aspectos técnicos

. Modifications needed as imported seeder is too heavy to use with local MTZ 80 tractors; and furrow openers are too weak for Central Asian soils
