Other claims from this paper (9)
- Observation Based on 3975 SNPs from genotyping-by-sequencing, sudangrass lines fell into three groups.
- Observation Cluster I, with 22 lines such as Haysudan, displayed shorter and thicker culms resembling sorghum with fewer tillers.
- Observation Cluster II, with eight lines including Balesudan, exhibited enhanced tillering and biomass production.
- Observation Cluster III, with 12 lines such as Piper, showed moderate traits but greater susceptibility to northern leaf blight.
- Intervention effect Higher cattle compost application rates increased nitrate-nitrogen accumulation in sudangrass.
- Observation Nitrate-nitrogen levels were higher in the first harvest but declined in the second.
- Recommendation To meet the 0.2% total nitrate-nitrogen limit, compost applications below 5 t・10 a−1 are recommended.
- Observation Some lines had nitrate-nitrogen concentrations near the regulatory threshold even at a high compost rate of 15 t・10 a−1 while maintaining high dry matter yields.
- Observation Lines such as GB13 combining high biomass production with low nitrate accumulation showed great potential as breeding materials.
