ABSTRAC Provision of seeds with the single bud chips method has the benefit of being more efficient in reducing the area of the nursery. In order to support the growth of single bud chips sugarcane seedlings in nurseries, bamboo root PGPR was given which made it easier for P to dissolve in the soil so that it was easily absorbed by plant roots. P element in the soil is needed by plants to meet plant nutrition so that if the P element needs are met, the plant will grow well. This study aims to determine the volume, frequency of application and interaction of bamboo root PGPR on the growth of single bud chips sugarcane seedlings. The study used a factorial Completely Randomized Design (CRD) with 15 treatments and 3 replications. The first factor is the volume of PGPR bamboo roots (K) which consists of five levels as follows: K0 = control/without PGPR, K1 = PGPR volume 5 mL/tan, K2 = PGPR volume 10 mL/tan, K3 = PGPR volume 15 mL /tan, K4 = Volume of PGPR 20 mL/tan. The second factor is the frequency of application (F) which consists of three levels as follows: F0 = 1 watering, F1 = 2 watering, F2 = 3 watering. The volume of PGPR bamboo roots as much as 15 mL/plant with a frequency of PGPR application of 2 times watering is the optimal provision for the growth of single bud chips sugarcane seedlings.

Cocoa seeds are seeds that have easy germination properties or are called recalcitrants. The technique of storing recalcitrant seeds cannot be dried below a critical moisture content, germinates easily and is not tolerant of low temperatures, so it is necessary to modify storage using sawdust storage media so that the seeds remain of good quality. The purpose of this study was to determine the effect of various doses of sawdust on the shelf life of cocoa seeds. Besides that, it also knows the best treatment of various doses of sawdust that can increase the shelf life of cocoa seeds. This study used a completely randomized design (CRD) with 6 treatments and 6 replications so that there were 36 experimental units. Parameters observed consisted of seed moisture content during storage, moldy seeds in storage and percentage of germination in seeding. Observational data were analyzed using ANOVA. If the results have a significant effect, then continue with the Duncan Multiple Range Test (DMRT) test at a level of 5%. The results showed that the best sawdust storage medium was 180 grams (A5) which could reduce the percentage of moldy seeds in storage.
