2.1 Short description of the Technology

Definition of the Technology:

Desho grass strip is a vegetative SWC measure used for stablizing the bund and provide fodder for animals.

2.2 Detailed description of the Technology

Description:

Desho grass is established by planting tillered cuttings. It establishes easily with little soil moisture. It is a perennial herbaceous grass which has massive fibrous root system that anchors the plant to the bind. It provides better cover to the bund and establishes agressively. The growth is upright with a growth potential of 90-120 cm depending on the fertility of the soil and regenerates quickly. It can grow and mature (ready for harvesting) at least once in a month and it requires only one seasontime rain to cover the whole bund.

Purpose of the Technology: The purpose of Desho grass is to stablize the bund and provide palatable grass for livestock.

Establishment / maintenance activities and inputs: Desho grass can be established/regenerate by tiller splitting and planting. The soil should be moist during establishment of Desho grass.

Natural / human environment: Desho grass can grow at 1500-2800 m asl and its best performs at an altitude of 1700-2800m asl.

2.5 Country/ region/ locations where the Technology has been applied and which are covered by this assessment

Country:

Ethiopia

Region/ State/ Province:

SNNPR

Further specification of location:

Sorro/Lintala, Ajacho

Specify the spread of the Technology:

• evenly spread over an area

If precise area is not known, indicate approximate area covered:

• 10-100 km2

Comments:

Importance in bund stablization of desho grass (Pennisetum pedecillatum Trin) is not well known. But it is fast growing and best for soil bund stablization in crop lands with multipurpose use. Desho grass increases the productivity of land taken by the bund. It is a good sources of forage. It also support food security efforts by substituting enset feeding.

Comments:

Major land use problems (compiler’s opinion): Population pressure, lack of land management skill, shortage of farm land, decline of soil fertility, low income (food insecurity)

Major land use problems (land users’ perception): Shortage of farm land, decline of soil fertility, low productivity per unit area of land and climate change (drought)

Grazingland comments: After Desho grass introduction the trends of grazing system change from open grazing on farm land to stall feeding and as a result land degradation problems are reduced in the area. The grass is used by cutoff and carry system.

Problems / comments regarding forest use: Focus on eucalyptus planting reduced crop production. Other multipurpose indeginous species should be considered.
