Alleycropping involves the planting of hedgerows across sloping lands or along contours and the use of alleyways between hedgerows for the growing of annual food crops.  Fast growing nitrogen-fixing trees or shrub legumes are commonly used as hedgrows.  They serve as windbreaks to alleycrops during strong weather and possible shade to crops.  Some of these are Ipil-ipil (Leucaena leucocephala); Kakawate (Gliricidia sepium); Katuray  (Sesbania grandiflora); Acacia (Acacia villosa); Flemingia congesta; and Tephrosia candida.  Forage grassess such as napier, king grass, vetiver, and sugarcane can also be used as hedgerows.  These provide continuous supply of fodder for farm animals.  The grasses can be mixed with the legume shrubs or other plants in the hedgerows strips.  Fruit crops such as banana, jackfruit, citrus, chico, coffee, papaya, mulberry, cashew and mango can also be combined with some hedgerows.  Annual food crops that can be grown in the alleyways are peanut, corn, rice, pineapple, grain legumes, rootcrops, and vegetables.
