N2  - In this study, Turkish red pine and Anatolian blackpine seedling production at different ages were planned with linear programmingmethod and maximizing the seedling revenues was aimed. In this respect,according to the assumptions used in the model, fields in various sizes such as10000 m2 area for one year old, 20000 m2 for two yearsold, 30000 m2 for three years old and 40000 m2 for fourand five years old seedling were separated in the nursery. On the other hand,balanced seedling production in consecutive years and consideration of demandincrease or decrease on the seedling production at any ages were main goals.For this, developed model was solved in three different formats deal with rapiddemand increase (RDI), slow demand increase (SDI) and demand decrease (DD)scenarios. Obtained results showed that if there is a rapid increase in demand,largest present value was 385310 $ and total produced seedling number was905262. Realization of slow demand increase has led to reduction of 6658 $(1.73%) in present value, and 17461 piece in produced seedling number. However,reduction of demand decrease caused to occur present value 24989 $ (1.93%) andproduced seedling number 61479 piece (6.79%) less.
