Abstract
Assuming that the area of a shelf can be utilized for cyclamen production prior to any other pot flower, more than two schemes were established for the production of cyclamen in greenhouse, considering the range of finished pot sizes and their profitability. Using profitability as a standard for comparison, these plans were compared, and the one yielding the most economic quantity was determined. In the process of cyclamen production, the number of sowing is determined during the first provisional planting so as to yield the necessary quantity of seedlings. Furthermore, after the production period of the first provisional planting, the quantity of seedling loss was assumed as 0. Assuming, however, that the rate of seedlings which can be planted in larger pots depends on the growth conditions of each seedling at the time of every provisional planting, the range of the finished pot sizes until the time of shipment is No. 4.5, 5, 6 and 7. Two things were considered for each size of each finished pot: the growth rate of the seedlings that are q5, q6 and q7, and the shipment prices which are a4.5, a5, a6 and a7. The research yielded the following result: Plane q6-q7, Plane a4.5-a5, and Plane a6-a7 Plane q6-q7 is useful in obtaining the most profitable scheme for cyclamen production, while Planes a4.5-a5 and a6-a7 provide conditions that make the first plane true.
