Response of Soybean (Glycine max) on Biopriming Applications with Trichoderma harzianum and Streptomyces sp

Soybean seeds are seeds that are prone to decreased physiological
quality because they have a high protein content of 43.90%.
One way to overcome this is by conducting a biopriming process.
Biopriming is one of the priming treatment by giving
biological agents that are able to improve the quality of seed
germination. The purpose of this study was to improve the
quality of seed germination and vigor with a combination of
biological agents in the form of Trichoderma harzianum and
Streptomyces sp. This study uses a factorial Separate Plot Design
consisting of main plots and subplots. The main plot is
the long immersion treatment consisting of 4 levels, namely
3 hours, 6 hours, 12 hours and 24 hours. Plots are microbial
treatments consisting of 3 criteria, namely without microbes,
Trichoderma harzianum and Streptomyces sp. The interaction
between immersion length treatment and several types of
microbes significantly gave the best results on normal sprouts,
abnormal sprouts, number of productive branches, number of
pods per plant, root length, density of upper leaf stomata, density
of lower leaf stomata, width of upper leaf stomata opening,
and broad opening of the lower leaf stomata. In the single factor
soaking time, soaking 6 hours, gives the optimal number
of nodules. In single factor microbial type, Streptomyces sp.
gave optimal value for germination and number of seeds per
plant. So all treatments for both immersion duration and various
types of microbes that are effectively used in are 12 hours
immersion and Streptomyces sp.
