__NOTOC__

International Development Enterprises of Colorado, USA, designed and tested a drum kit system which can irrigate 520 vegetable plants. The drum kit consists of 130 pipes (1-mm diameter) called micro-tubes, fitted to 5 rows of 12-mm diameter PE laterals. Water from the drum flows out in a small stream from all 130 micro-tubes. The water then spreads out in a circular pattern to about 0.5-m radius. Four plants are planted in each of the circles.

 

'''Uses of a drum system'''<br>

 

A drum system covering 5 beds each 1 m wide and 15 m long can be used to grow 250 plants (tomato, egg plant and similar plants requiring a spacing of 60 cm along the plant rows); 500 plants (spinach, cabbage, kale, pepper and similar plants requiring a spacing of 30 cm along the plant rows); or 1,500 plants (onion, carrot and similar plants requiring a spacing of 10 cm). The drum system also offers water storage and control through a control valve, making it possible to fill the drum for irrigating at another time.

 

Six examples are presented: the KARI drum system from Kenya, the Waggon Wheel system from South Africa, the Family, Plastro and Micro-Tal systems from Israel, and the IDE drum used in India.
