How many bags of potatoes can an acre produce in Kenya?

One acre in Kenya produces 120-450 bags of Irish potatoes (90kg bags), with the national average at 250-300 bags per acre. High-altitude areas like Nyandarua, Molo, and Timau achieve 350-450 bags/acre with certified seeds and proper management.

Which is the best potato variety in Kenya?

Shangi is the most popular variety, yielding 250-350 bags/acre with good taste and market demand. Dutch Robjin yields 300-400 bags/acre and resists late blight. Markies is ideal for processing (chips/crisps), yielding 350-450 bags/acre in high-potential areas.

How much fertilizer do potatoes need per acre in Kenya?

Potatoes need 200-300kg NPK (17:17:17 or 23:23:0) at planting, plus 50-100kg CAN at earthing-up (4-6 weeks). This costs KSh 24,000-35,000 but is essential for high yields. Potatoes are heavy feeders requiring more fertilizer than maize or beans.

What is the cost of farming one acre of potatoes in Kenya?

Total production cost is KSh 120,000-180,000 per acre, including land preparation (KSh 15,000), certified seed potatoes (KSh 45,000 for 10 bags), fertilizers (KSh 30,000), fungicides (KSh 15,000), labor (KSh 25,000), and harvesting (KSh 20,000). High costs but also high returns.

Is potato farming profitable in Kenya?

Yes, highly profitable. With moderate inputs (KSh 150,000) and average yield of 300 bags at KSh 3,500/bag, you earn KSh 1,050,000 revenue and KSh 900,000 net profit (600% ROI). Potatoes mature in 3.5-4 months, allowing 2 crops per year in some regions.

How Many Bags of Potatoes Per Acre in Kenya 2025 | Irish Potato Yield Calculator

In Kenya, one acre of land produces between 120 to 450 bags of Irish potatoes (90kg bags) depending on the region, variety, fertilizer application, and disease control. The national average is 200-250 bags per acre for smallholder farmers using certified seeds with moderate inputs. High-performing regions like Rift Valley (Nyandarua, Molo, Timau) achieve 350-450 bags per acre with optimal conditions, while lower-potential areas produce 120-200 bags per acre.

Complete Guide: How Many Bags of Potatoes Per Acre in Kenya

Quick Answer

One acre of land in Kenya produces 120 to 450 bags of Irish potatoes (90kg standard bags), with the national average being 200-250 bags per acre for smallholder farmers. The exact yield depends on:

Region & Altitude: High-altitude areas (Nyandarua, Molo, Timau) produce 350-450 bags/acre, while lower areas produce 120-200 bags/acre
Seed Quality: Certified seeds yield 40-50% more than farm-saved seeds which accumulate viruses
Fertilizer Application: Potatoes need heavy NPK fertilization (200-300kg/acre) - proper fertilization can triple yields
Late Blight Control: This disease can destroy 100% of crop without weekly fungicide sprays
Proper Hilling (Earthing-up): Creates space for tuber formation and prevents greening
