How You Can Earn Shs20m From An Acre Of Castor Seeds With Minimal Investment

Castor seed oil plant popularly known as Ensogasoga is something most Ugandans see but don’t know its value. Traditionally, many locals deemed the seeds of this useful plant poisonous. The plant was restricted to lighting purposes. That’s why they would tie these seeds in papyrus or rigs and light them as a source of fire.                          The abundant crop in Uganda was also carried to Egypt thousands of years ago through River Nile. The culture was also similar and very prevalent in Egypt, especially among the Egyptians, when they would go to the pyramids and use castor seeds as a source of fire.

Caster seeds have oil which ignites the fire.

It was not until the Jamaicans discovered the way of roasting these seeds to remove the poisonous compound through a process known as ricin, which had beaten our forefathers. They thought that the poison is within the seed yet it was only in the outer cover. So the the Jamaicans started roasting it and after that they could press it to form oil and that oil was known as the Jamaican Black Castor. Given the fact that  Jamaica has many Rastafarians with dreadlocks, they were breaking, so castor oil was used to oil the dreadlocks to stop them from breaking.

This same principle of detoxifying the seeds spread even to this country, the same way soybeans are roasted to remove the anti-nutritional factor known as Trypsin inhibitor. Castor seeds are roasted to remove the chemical and the Castor oil can be edible.

Getting Started

Julius Nyanzi, the CEO at Prof Bioresearch, says four tins of castor seeds can cover an acre. Each tin is sold at Shs10,000, meaning one will spend about Shs40,000 on an acre.  He says seeds are soaked in milk overnight. This improves on the germination process. A natural anti-fungicide trichoderma is added to prevent the seeds from rotting in the soil.

Castor is planted at a spacing of four meters by four meters, meaning that an acre will accommodate 400 trees.     The crop takes a lot of space with many branches. Castor tree takes 6 months to start producing seeds. Each tree can produce 10kgs of seeds. This means a farmer can get about 4,000 kilograms from an acre.

A kilogram of castor seeds is at Shs5,000, meaning that a farmer can earn as high as Shs20m from an acre. Castor is an annual crop, meaning that one has to plant a new crop in another season.
