Banana Research Facility is the Banana Farm's path 1 tier 4 upgrade in Bloons Monkey City. Instead of generating bananas, it generates five crates of bananas, each worth $400, for a total of $2,000 per round. (In the Flash version, it instead produces 10 crates per round, each worth $300, for a total of $3,000 per round.) In the multiplatform version, upgrading a Banana Republic into a Banana Research facility in the middle of a round causes it to produce crates at the same rate as a Banana Republic for the rest of the round.

The editor who added this notice elaborates: how to progress into brf, best ways to maximize brf and stuff
|
Banana Research Facility (BRF) gives the biggest boost of income, minus a single Monkey Bank's Rank 5+ end-of-round effect with high enough unspent cash, and is very cost efficient. Buy it from a setup of many Banana Plantations and a single Banana Republic (or multiple on limited land maps), then sell enough Farms to rush the BRF. Then rush Valuable Bananas to maximize its income generation. If Village is enabled, always discount the Farm before upgrading, which will save a lot of money.
In the multiplatform version, the cash generation bug allows it to produce significantly more cash if bought mid-round, so any purchases of BRF from a Republic should be done at this point if possible.
Trivia
- In the Flash version, Banana Research Facility is the face of the Legendary card for the Banana Farm in Monkey Knowledge.
