The purpose of this research paper is to examine the monthly minimum temperature for March and April and the average precipitation for the months of June, July, and August in Southern Illinois to observe how they affect the yearly yields of apple and peach production at Flamm Orchards in Cobden, Illinois. The data that was observed is only a portion of the total acreage that is in production at Flamm Orchards. There was one block of apples selected and one block of peaches, both of which had the most harvest records available for use. There has been minimal research done that specifically analyzes how weather variables in particular, temperature and precipitation, affect apple and peach yields. The results from the model show that the significance of minimum temperature in March and April and precipitation in June, July, and August is minimal in accounting for yield variation of apples and peaches. This research will provide crucial data to growers not only in Southern Illinois, but nationwide as to whether or not their climate is suitable for the production of apples and peaches and what to expect for yields earlier in the season.
