2.1 Short description of the Technology

Definition of the Technology:

the SWC technology entails growing of markhamia lutea trees like food crops involving application of manure and mulch.

2.2 Detailed description of the Technology

Description:

Markhamia lutea are grown in lines in the homestead. They are mulched, prunned and organic manures applied. After 2-3 yrs, harvesting of poles can commerce.

Purpose of the Technology: for addition source of income, windbreak, poles for construction and firewood.

Establishment / maintenance activities and inputs: The trees are free seedlings. Wildlings are picked and planted in rows. They are raised in a nursery before transplanting.

Natural / human environment: technology is located in a semi arid area. It is vegetative involving trees. Soils are sandy loams and are shallow.
