1.3 Conditions regarding the use of data documented through WOCAT

The compiler and key resource person(s) accept the conditions regarding the use of data documented through WOCAT:

Ja

2.1 Short description of the Technology

Definition of the Technology:

Multiple cropping is an agronomic practice of growing two or more crops on the same land simultaneously in a given growing season

2.2 Detailed description of the Technology

Description:

Growing of different types of crops in the same field. The crops grown together are, however, harvested at different times. In the Konso case the farmers are used to growing of 10-15 types of crops on the same area. The purpose is to avoid risk (some crops are more resistant or escape the adverse conditions like drought, pest and disease) and to get variety of produce at a time. Annual crops are sown/planted every season. Binual and perenial crops are planted and managed according to their seasonal calendar in which the crops grown to provide better production. Low fertility status, unpredictable and erratic rainfall, pest and diseases are some of the constraints limiting productivity.

2.6 Date of implementation

If precise year is not known, indicate approximate date:

• more than 50 years ago (traditional)

2.7 Introduction of the Technology

Specify how the Technology was introduced:

• as part of a traditional system (> 50 years)

Comments (type of project, etc.):

The emergence of the technology appears to be an attempt to avert/minimize the risk that could occur owing to recurrent drought. It is a coping mechanism to adverse climatic conditions.

3.1 Main purpose(s) of the Technology

• improve production

3.2 Current land use type(s) where the Technology is applied

Cropland

• Annual cropping
• Perennial (non-woody) cropping

Number of growing seasons per year:

• 2

Specify:

Longest growing period in days: 90 Longest growing period from month to month: Mar - May Second longest growing period in days: 50 Second longest growing period from month to month: Aug - Oct

Is intercropping practiced?

Ja

Is crop rotation practiced?

Ja

Comments:

Major land use problems (compiler’s opinion): Most of the lands without SWC are not treated because they are communal holdings.

Major land use problems (land users’ perception): Most of the lands without SWC are those communally held and used.

Type of cropping system and major crops comments: Inter cropping, sequential cropping, rotational cropping and monocropping in some potential flatter areas

3.4 Water supply

Water supply for the land on which the Technology is applied:

soil erosion by wind

• Et: loss of topsoil

chemical soil deterioration

• Cn: fertility decline and reduced organic matter content (not caused by erosion)

Comments:

Main type of degradation addressed: Wt: loss of topsoil / surface erosion

Secondary types of degradation addressed: Et: loss of topsoil, Cn: fertility decline and reduced organic matter content
