Only a 50 Kilograms of Irish potato seed are required per acre when grown at a spacing of 15-20cm within rows.


Make sure you do a soil test to apply right fertilizers and manures. Make sure the plant has adequate moisture and fertilizer during the tuber formation. Apply DAPP at 200 kg per acre and on acidic soils make sure you apply CAN fertilizer at 120kg per acre, depending on the result of soil analysis
