Other claims from this paper (5)
- Intervention effect PUP at 100, 300 and 500 mg/L significantly increased tobacco seedling fresh weight by 24 %-70 % compared with water (CK) in acidic soil.
- Intervention effect PUP-3 treatment enhanced the abundances of the beneficial bacteria Gemmatimonadaceae, Bacillus and Nitrospira in the tobacco acidic-soil system, possibly associated with increased soil pH and nutritional status.
- Intervention effect The abundance of functional genes in biosynthesis pathways of carbon metabolism, amino acids, secondary metabolites and fatty acids increased with PUP amendments.
- Intervention effect The higher concentration PUP-5 did not show further gains in tobacco growth beyond PUP-3 (300 mg/L).
- Recommendation The authors conclude that 300 mg/L is the optimal PUP application concentration in tobacco cultivation.
