Abstract

Commodity development requires site selection which should be established prior to large scale development. The land suitability criteria for cashew are not presently available. The relationship between the biophysical aspects, especially land and soil with commodity productivity, is also not known in depth. The objective of this study is to establish the criteria of land suitability for cashew in Indonesia, based on its production and land characteristics. Cashew plantations in 5 provinces were sampled. The data of production per tree per year were obtained from farmers, while the soil was sampled and analyzed in the laboratory. Age-adjusted cashew production was used as the yield response and plotted against land characteristics. Boundary lines resulting from the scatter of points were described; these lines produced the limits of land suitability criteria. The criteria were established using a projection of the intersection between the boundary line and yield interval. The criteria were also built in accordance with the productivity index of FAO for the internal boundary inside the S (suitable) class and by calculating the break-event point production for the boundary between S (suitable) and N (nonsuitable) order. The main result of this research is land suitability criteria for cashew.

Summary

Introduction

The cashew (Anacardium occidentale L.) is a prospective commodity in Indonesia, and its cultivation issues are relevant to the country’s development both as an export commodity and in regard to environmental conservation. At the beginning of Indonesia’s agricultural development, planting of the cashew was implemented for greening programs and reforestation. With the increase of prices, issues of cashew development began to shift from land conservation to more economic considerations. Indonesia is the fifth largest cashew producer in the world after Nigeria, India, Cote d’Ivoire, and Vietnam. One of the problems encountered in the development of cashew in Indonesia is the low productivity. Compared to the long-term target production of this commodity in Indonesia of >1,000 kg nuts⋅Ha−1⋅year−1 [6], actual average production is very low. One of the efforts to increase productivity is planting the commodity only on suitable land
