Castor Seed Yield

Average seed yields range from 900–1000 kg/ha under irrigation, and 500 kg/ha without adequate moisture. Some improved open-pollinated varieties in Brazil yield 1,300 kg/ha, with exceptional yields up to 5,000 kg/ha. Average Indian yields are about 1000 kg/ha.

Under exceptional circumstances in the state of Gujarat in India, seed yields of 6000 Kg / hectare have been recorded, but it should be noted that these yields have been registered only for some limited growth areas.

Castor Oil Yield

The Indian variety of castor has 48% oil content of which 42% can be extracted, while the cake retains the rest.
