Planting patterns in rubber agroforestry (Hevea brasiliensis) developed by the communities of Menggala Mas Village, Lampung Province, Indonesia

The agroforestry system provides important economic and ecological benefits for local communities, one of which is obtained from the application of planting patterns and plants species in it. This research aims to explain the planting pattern of rubber agroforestry developed by the community in Menggala Mas Village, Lampung Province, Indonesia. The approach in this research is qualitative. Data collection methods included observation, in-depth interviews, and documentation studies. The planting patterns of agroforestry system on their rubber plants were analysed. The research results showed that there are three agroforestry planting patterns implemented by the community, namely, alley cropping, trees along border and random mixture. The dominant combinations in alley cropping were rubber/karet (Hevea brasiliensis) – pulai (Alstonia scholaris) and rubber–mentru (Schima wallichii) – kayu afrika (Maesopsis eminii). The dominant combinations in trees along border were rubber–akasia (Acacia auriculiformis), rubber–jackfruit (Artocarpus heterophyllus) – cempedak (Artocarpus integer) and rubber–petai (Parkia speciosa) – jati (Tectona grandis). The dominant combinations in the random mixture were rubber–jengkol (Pithecellobium lobatum), rubber–petai–jengkol–akasia, rubber–jackfruit–cempedak, rubber–pulai–mengkudu (Morinda citrifolia L.) – jengkol and rubber–banana (Musa paradisiaca) – gadung (Dioscorea hispida) – sungkai (Peronema canescens Jack). Forty-one plant species were found. The local community wants to develop this planting pattern because the rubber agroforestry planting pattern can provide direct and indirect benefits such as a greater variety of plants which can increase their income; also, the products can be sold or consumed by the family, as a fence, fire break or barrier to other farmers’ land, can provide shade to reduce hot temperatures when farmers are working, and can reduce the risk of flooding and soil erosion to support soil and water conservation within the ‘Omou’ (garden/forest). The government and agricultural extension workers need to carry out regular guidance and outreach programmes regarding rubber agroforestry development strategies to increase public knowledge.
