Rich farmers who dont have to worry much about seed cost can discount that factor and look into other options too, as illustrated in the chart #2 below:Coffee plantation yields better dividends per hectare, the 3 day long wait offsets other benefits. Hence it is always advisable to go for Potato during the nights and the day times can be filled busy with plowing for and harvesting Grapes.
