Abstract

Chickpea ranks third among pulses, fifth among grain legumes, and 15th among grain crops of the world. In 2006, the world chickpea cultivation area was 10.7 Mha with over 8 Mha grown in India, Pakistan, and Iran, with a further 1 Mha grown in other countries of Asia, the Middle East, and Canada. Total production was 8.4 Mt, and the average yield was 772 kg/ha (FAOSTAT 2006). Although chickpea is cultivated in about 50 countries, 95% of its area is in the developing countries where South Asia alone covers almost 71% of the world chickpea harvested area. Most of the chickpea harvested is consumed locally and the global trade is about 12% of the total production. The global demand for chickpea is projected to be 11.1 Mt in 2010. Under optimum growing conditions, the yield potential of chickpea is 6 t/ha (Singh 1987), which is much higher than the current global yield average of ~0.8 t/ha (Ahmad et al. 2005).
