Sherman's Planet

From Memory Alpha, the free Star Trek reference

Sherman's Planet was a disputed planet located near the Federation-Klingon border, in an area first mapped by astronomer John Burke in 2067. (ENT: "In a Mirror, Darkly, Part II")

Following the Federation-Klingon War in 2267, and per terms of the Organian Peace Treaty, ownership of Sherman's Planet could be assumed by the side that could most effectively develop it. The Federation's intentions for Sherman's Planet were to use it to cultivate quadrotriticale, a grain well adapted to the planet's climate. (TOS: "The Trouble with Tribbles")

The Federation succeeded in best developing Sherman's Planet. However, by 2269, the planet had been struck by famine. On Stardate 5392.4, the USS Enterprise, under Captain James T. Kirk, was assigned to escort two robot ships hauling an improved grain, quintotriticale, to the planet to alleviate the plight. (TAS: "More Tribbles, More Troubles")

Sherman's Planet also appeared in the star chart Data and Picard were studying in stellar cartography in 2371. (Star Trek Generations)
