Frequently asked questions

What crops grow well in Mafia?

Cashew, Cassava, Taro, Robusta coffee, Cotton all rate well in Mafia — scored against its own rainfall, soil and terrain rather than a national average.

When should I plant Cashew in Mafia?

In Mafia the window for Cashew runs 6 Oct 2026 to 1 Jun 2027.

Is there a farming app that works in Mafia?

Divisi does. It reads Mafia's own rainfall, soil and terrain rather than a national average, so the planting dates and crop shortlist on this page are the same ones the app works out for a field here — then dates each job for that field, and keeps working with no signal.

Is this exact for my own field?

No — these are readings taken across Mafia, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
