Abstract
Jajar Legowo (Jarwo) Super is an improved technological innovation used to increase the productivity of lowland rice varieties. Related to the introduction of the technology, it is necessary to conduct in-depth research on some components of Jarwo Super including new Superior varieties, application of Agrimeth biofertilizer and planting system on growth and yield. The research was aimed to investigate the response of the new Superior variety to biofertilizers and different planting system. The study was conducted in Koya Barat, District Muara Tami, Jayapura, from June to September 2018. The treatments were arranged in a split-split plot design with three replications. The main plot was biofertilizers consist of Agrimeth and without Agrimeth. As subplot was planting methods Jarwo, consist of Jarwo 2:1 (25 cm x 12.5 cm x 50 cm) and Jarwo 4:1 (25 cm x 12.5 cm x 50 cm). As sub-sub plots were new superior variety (NSV): Inpari 33 and Inpari 43, respectively. The results showed that the combination of treatment of Agrimeth and without Agrimeth with planting system Jarwo 4:1 on Inpari 33 gave the higher grain yield compared to other treatments of 7.44 t/ha and 7.33 t/ha. The application of Agrimeth biofertilizers does not have a significant influence in increasing the yield of rice grain. Jarwo system 4:1 gives a dry grain yield of 6.30 t/ha which is higher 0.53 t/ha compared to Jarwo 2:1 (5.77 t/ha).
