Abstract
One of the efforts to increase the growth of
white turmeric (Curcuma zedoaria) rhizomes and promote environmentally
friendly, sustainable agriculture is to utilize Plant Growth Promoter
Rhizobacteria (PGPR). The present research aimed to determine the effect of
PGPR concentration on the growth of white turmeric rhizomes. The research was
carried out in the physiology and development laboratory, department of
biology, faculty of mathematics and natural sciences, Sriwijaya University. The
research design used in this study was a Complete Randomized Design with four
treatments of PGPR concentration (0, 62.5, 125, and 187.5 ppm) and five
repetitions. The data obtained from observations and measurements is
statistically analyzed using the analysis of Variance and Duncan’s multiple
range test. The results showed that PGPR treatment could increase the growth of
white turmeric rhizomes. Concentration of PGPR at 125 ppm gave the best results
and had a significant effect compared to no PGPR treatment in stimulating the
growth of white turmeric rhizomes on the parameters of time of shoot emergence,
shoot height, number of shoots, number of roots, and root length. The PGPR
concentration of 62.5 ppm gave a significantly significant result compared to
the average number of leaves without PGPR treatment.
