The Effects of Different Agroforestry Patterns on Agricultural Crops Production in Community Forest in Gunungkidul Indonesia

Abstract

The development of community forest in Gunungkidul is followed by the changes in management orientation from conservation to be an economic purpose. These changes lead to the changes in land use patterns from traditional to intermediate and even an advanced agroforestry. It could threaten the food security in Gunungkidul for once the trees are grown on the forest land, then the production of agricultural crops is reduced and even unproductive. Local farmers are generally engaged with the local wisdom in managing the forests in which to combine agricultural crops with forestry trees, therefore it is necessary to examine the agricultural crops production in the community forest on different agroforestry patterns. The purpose of this study is to calculate the agricultural crops production from the community forest based on different agroforestry patterns.The method used was survey to the respondents who own the community forest combining agricultural crops and forestry trees. The number of respondents were 120 people. The results showed that the dominant agroforestry pattern is the Random Mixture composed mainly of teak. The dominant agricultural crops production on the trees along border pattern is rice which is 733.5 kg · ha−1, the alley cropping pattern is corn which is 1000 kg · ha−1, the alternate rows pattern is cassava which is 1562.5 kg · ha−1 and the random mixture pattern is corn which is 249.4 kg · ha−1. The amount of production on each pattern reflects the suitability of the agroforestry pattern with the type of food crops.
