Abstract :
The decline in productivity of cocoa plantations in Indonesia is partly due to the low quality of seeds which refers to the impeded growth of cultivated cocoa nurseries. Of course this is a major problem. Bio-priming treatment with microbial Plant Growth Promoting Rhizobacteria (PGPR) can produce indolasetic acid hormone (IAA) in plants to improve the quality of seed germination. Bio-priming is the treatment of soaking seeds with microbes to improve the quality of plant growth. This study aims to determine the effect of bio-priming Plant Growth Promoting Rhizobacteria bamboo rhizosphere on cocoa seed germination. This study was arranged in the form of a two-factor factorial design (F2F) in a randomized block design (RBD). The use of cocoa seed type as the first factor consisting of GTB (Gantarangkeke Bantaeng) local cocoa seed and MCC 01 cocoa seed and seed immersion treatment at PGH rhizosphere bamboo PGPR concentrations as the second factor consisting of 0% concentration (control), 5%, 10% and 15%. The results obtained indicate that the administration of seeds with bamboo rhizosphere PGPR affects the germination 100.00%, the speed of seed growth 7.14%/etmal and the abnormal seed 10.00%. So that bio-priming of seeds with bamboo rhizosphere PGPR provides an effective influence on seeds germination.
