Disease–Free Seed Ginger Production Technology (G3, G4 And G5) in the Field |Biomedgrid

Increasing threats of ginger from bacterial wilt: Ralstonia solanacearum, is impacted to ginger production and market of farmer in Thailand. The objective of this study was to find the integrated ginger production system that are produced high yield stability and able to replanted in the same area for farmer's well-being sustainable development. This study evaluated the integrated ginger production technology consist of cultivate management, bioproduct from Bacillus subtilis BS-DOA 24 strain for controlling bacterial wilt of ginger and disease-free rhizomes seeds from tissue culture of ginger three generations (G3, G4 and G5) at Phetchabun Highland Agricultural Research Center during October 2016- September 2019. The rhizomes seed production after planting 11 months was free from bacterial wilt disease. The sprouting ginger seed germination percentage after 2 months of G3, G4 and G5 were 92, 97 and 99%, respectively. Total yield of DOA's technology in G3, G4 and G5 showed 3,248, 10,133 and 10,568 kg/rai (20.3, 63.33, and 66.05 tons/hectare), respectively that the yield of DOA's G5 was significantly higher than farmer method (6,725 kg/rai or 42.03 tons/hectare).
