Abstract
Rice production need to be increased every year and Jajar Legowo Super is one of some improved technological innovation used to increase productivity of lowland rice variety. Related to the introduction of the technology, it is necessary to conduct deeper research on some components of Jarwo Super including new superior varieties, application of Agrimeth biofertilizer and planting system on growth and yield. The study was conducted in Koya Barat, District Muara Tami, Jayapura Municipality in seconde planting season start from June to September 2018. Site was selected deliberate with consideration that the district was the location of Jarwo Super rice culvitation activeities. The treatments were arranged in a split-split plot design with three replications. The main plot,was biological fertilizers consists of (P1) using Agrimeth biofertilizers and (P2) without using Agrimeth biofertilizers. As sub plot was planting methods legowo, consist of Jarwo (J1) 2:1 (25 cm x 12.5 cm x 50 cm) and Jarwo (J2) 4:1 (25 cm x 12.5 cm x 50 cm). As sub-sub plot were VUB, (V1) Inpari 33 and (V2) Inpari 43, respectively. The results showed the combination of treatment of agrimeth biofertilizers and without agrimeth biofertilizers by planting legowo 4: 1 and using Inpari 33 varieties gave the higher grain yield compared to other treatments 7.44 t / ha and 7.33 t / ha. The application of Agrimeth biofertilizers does not have a real influence in increasing the yield of rice grain. Jarwo system 4: 1 gives dry grain yield 6.30 t / ha which is higher 0.53 t / ha compared to jarwo 2: 1 (5.77 t / ha)
