What yield and income range does Senna give per acre in dryland?

Senna leaf yield per acre varies with rainfall, soil and management, and dryland yields are naturally lower than irrigated, so plan with conservative ranges and verify locally. Price per kg of dry leaf is trader and quality driven and swings by year, with clean green leaf earning more than dusty mixed lots. Because Senna needs little water and tolerates poor soil, input cost is low, which protects your downside even in a weak price year, and that low cost is the real attraction in dryland. But do not budget on a single high price a promoter quotes. Build your plan on the low end of yield and price, confirm a buyer and a written rate, and treat all numbers as unverified ranges until you have actually sold a lot.
