In crop production, the latest method of rapid propagation of planting materials is the in vitro method. However, the in vivo method has also the potential for rapid propagation and it could be adopted by any farmer. The plantlets are adaptable to varied climatic conditions, therefore the plantlets could be directly transferred to the field. This study aimed to evaluate the performance of the different ginger rhizome sizes in producing plantlets as planting materials and to determine the most profitable size for plantlet production. Result revealed a comparable highest number of plantlets per sett produced in the 125g and 150g rhizomes. However, the smallest size of rhizome at 50g produced the most number of plantlets per kilogram sett. Bigger sizes of seed rhizomes (75g, 100g, 125g, and 150g) were comparably profitable in producing plantlets as planting materials as revealed by ROI ranging from 106.00% to 107.81%.
