Coffee agroforestry management (#journal)

Agroforestry coffee production increased by native shade trees, irrigation, and liming

Agroforestry systems usually include shade trees, providing a large diversity of fauna and flora. Shade trees are, however, being removed to increase crop production in many tropical regions. We evaluated the importance of shade tree management for crop production in the context of management practices. Management practices included fertilization, liming, coffee pruning, weeding, and irrigation in 113 coffee agroforests in Kodagu, India. Results show that a rise of 100 shade tree per hectare increased production of berries by 5.6 % and bean size by 6.25 %. Irrigation and liming increased berry production respectively by 16 and 20 %. These management interventions offset the relatively small effect of reducing shade density.
