Abstract

Seeds as planting material play an important role in agricultural development. The high demand for oil palm sprouts causes the long germination time to become an obstacle for consumers and seed producers. The aim of this research is to examine varieties on germination capacity of oil palm seeds. Research was conducted at the PPKS Seed Processing Unit on nine PPKS varieties (Simalungun, PPKS 540, Yangambi, PPKS 239, PPKS 718, Dumpy, Avros, Langkat, and PPKS 540 NG). The parameter observed was the germination power (DB) of the seeds. The treatment given in the germination process for all varieties is carried out to ensure that the environment is favorable for germination (according to the SOP). Observation results showed that PPKS 540 variety had the highest DB (84.9%), followed by Simalungun (81.46%), PPKS 540 NG (75.46%), Langkat (75.43%), Dumpy (73.41 %), PPKS 718 (72.29), Yangambi (68.81%), PPKS 239 (65.74%), and Avros (56.92%). This is thought to be due to the influence of internal factors, related to the conditions of the germinated seeds, both genetics and hormones, as well as external conditions which include optimal water, temperature and oxygen treatment during germination. The results show that the water content (KA) of the seeds in the soaking period (I) was 16-20%, and soaking (II) was 19-22%, all processed seeds were still at a safe level of water content for the process of breaking dormancy of oil palm seeds. The characteristics of parent tree of the seed variety are the cause of differences in seed germination

Abstract

This research aims to examine the production of superior oil palm seed bunches in the PPKS Marihat Unit.Data and information collection is carried out using direct and indirect methods. Field observations carried out include: Area conditions including: topography, soil conditions, Plant conditions including: plant growth, plant population and fruit condition, Technical culture conditions: fertilization, harvesting of seed bunches. Supporting data collected includes: garden production data, rainfall and fertilization data. The research results are bSeveral factors that cause low production include: a) fertilizer amounts that are far from plant needs, given the time, type; b) plant density which is classified as less than optimal due to ganoderma attacks. The number of bunches is the result of plant physiological processes, mainly determined by the ecophysiological conditions of the plant around 24 months before harvest, where the decrease in production in the number of bunches harvested in 2020 is the result of ecophysiological conditions in the form of fertilization which is not appropriate in 2019-2020.
