2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
Growing variety of vegetables in salt affected soils.
2.2 Detailed description of the Technology
Description:
The farm is 5 faddan in area. Vegetables such as eggplants, parsley, spinach and pumpkin are planted in part of the farm on a rotational basis. In the remaining small area other crops which includes rhodes, maize, banana, alfalfa and date palms are grown.
Livestock are part of the farm business from whch substational income is obtained by the household.
Purpose of the Technology: To earn income that suports the livelihood of the household.he income i generated from vegetables, fruits and livestock products.
Establishment / maintenance activities and inputs: Vegetables are established in direct seeding and fruit trees are established in direct seedlings. Seedlings are bought from commercial nurseries.
Natural / human environment: The farm is located in a flat area along the oman sea coast. Most of the farmers in surounding area
