The Appropriate of Plant Propagation Technology of Yam (Dioscorea alata L) to Reduce Multiplication Ratio

Abstract

namely the weight of tuber cuttings and tuber cuttings part. The weight of tuber cuttings used was 10-15 g; 20-25 g; 30-35 g; 40-45 g; 50-55 g. Tuber cuttings consist of the base, middle, and tail. These treatments are arranged in a two-factor factoriall design. The tuber cuttings were planted with a spacing of 80 cm X 80 cm on beds with an area of 2.40 m 2.40 m, and were repeated three times. Each bed is planted with 16 tuber cuttings. The result shows that the small sett tuber can reduce the multiplication ratio of D.alata. Sett tuber 50-55 g get the highest yield tuber (2158g) and multiplication ratio 0.023.
