I think you meant 50k per ton of cane. Here are the numbers:
1. A TATA carries app. 15 tons of cane. So a farmer gets 750k
2. From a ton, millers extract 9% (90kg) of sugar
3. A kilo of sugar is at 3k
4. So, from a 15 ton lorry, millers get 15 x 90 x 3k = 4m.

I gather the farmers receiving 50k per ton are those begging colleagues who have contracts with millers. The latter supply at 90k; thus getting UGX 1.35m a lorry. These are the ramifications of Busoga leaders misleading their people to refuse zoning suggested by millers.

Here is what happened: when people refused zoning intended to contract farmers to particular millers as guarantee for assured supply, millers resorted to producing their own cane. SCOUL planted over 15 sq.miles of cane; and Kakira planted 10 sq.miles more.

Consequently, un contracted out-growers (in search for market price) turned into losers. They have no buyer, and can only sell when they beg their contracted colleagues to buy from them and on-sell to the millers. These are the ones receiving 50k (and after ‘kneeling’)

One problem, Ugandans listen more to rhetoric, politics and emotional talk than economics. Nowhere in the world are plantation crops grown laissez-faire. They’re done under contract farming model. Why? Small-holder farmers are unreliable. They supply you twice and switch to boda

Millers are seated on unsold stocks of sugar due to regional market issues and Covid impact. Yet there’s also increased production of cane. Whenever there’re market issues for agricultural produce (cobweb), the first victim is the un contracted farmer.
