Effect of bio-liquid organic fertilizer on the growth of Dipterocarpus alatus Roxb seedlings in the pot experiment

Aims: The objective of this research was to study the effect of bio-liquid organic fertilizer on the growth of Dipterocarpus alatus Roxb seedlings (30 days old) in the pot experiment. Methodology and results: For the production of bio-liquid fertilizers, distillery slop; molasses and bio-methane waste water were fermented with plant growth promoting bacteria, which had potentials for nitrogen fixing, phosphate solubilizing and potassium solubilizing properties. It was found that treatment no. 13 (molasses + three bacterial isolates (PGPB), 30 days of fermentation) presented the best result on the growth parameters of D. alatus Roxb including root length (21.67 cm), shoot height (20.33 cm), root fresh weight (1.49 g), shoot fresh weight (3.61 g) and total biomass (4.13 g). Moreover, using liquid organic fertilizer produced from molasses supplemented with bacteria had higher growth-promoting effects on D. alatus than the effective microorganisms (EM). Conclusion, significance and impact of study: To covert agricultural residues to the valuable product was the aim of this work. In our experiment, we found that molasses and bio-methane waste water were suitable for using as a material to produce liquid organic fertilizers which were beneficial for promoting growth of D. alatus seedlings.
