Mr. Onyango has 4 hectares of arable land, 1.5 hectare of which is under wheat, 0.5 hectare under maize, 0.3 hectare under fodder crops and the rest is under either improved grass ley or natural grass. He wishes to know whether replacing 0.3ha of maize with potatoes the following season would be worthwhile. The fertilizer rate would have increased from 2 bags per hectare for maize to 2.5 bags per hectare for potatoes an extra 40 days of casual labour per hectare would be necessary as a result of the change. Average yields of maize and potatoes are 56 and 90 bags per hectare respectively. The price are Ksh. 1200 per bag of maize and Kshs. 300 per  bag of potatoes. Seeds costs are Kshs. 1350 per 10 kg of maize and Kshs. 200 per 50 kg of potatoes. DAP fertilizer costs Kshs. 1400 per 50 kg bag. Labour is paid at Kshs. 150 per man day.
