Indian farmers are likely to expand soybean planting areas by nearly 15 percent after the government raised edible oil import tax to the highest level in more than a decade, lifting domestic oilseed prices to nearly two-year highs. Higher production of the main summer-sown oilseed could help India, the world’s biggest vegetable oil importer, trim costly imports from Brazil, Argentina, Indonesia and Malaysia. It could also mean a boost in exports of soymeal, a key animal feed, to Asian buyers such as Japan, Vietnam and Bangladesh. Soybean has been giving farmers good returns. Indian soymeal once accounted for nearly a quarter of all Southeast Asian imports, but the country’s share has been falling due to rising domestic soybean consumption amid stagnant production.
