YIELD AND FINANCIAL ANALYSIS OF <em>AZADIRACHTA</em> <em>INDICA</em>

Abstract

Yields were determined by site index classes and alternative spacing regimes for Azadirachta indica using data from plantations in Thailand. For all site index classes, a 2 x 4 m spacing yielded greater volume than a 4 x 4 m spacing. Net present value was used to determine the financially preferred rotation ages and spacing regimes. The 2 x 4 m spacing was preferred on only the highest yielding site whereas, for the lowest yielding site, no planting was preferred. A sensitivity analysis was conducted by varying the economic assumptions regarding discount rate, prices and costs. A break even analysis was also conducted.
