Abstract

The productivity of swampland in North Kalimantan, is still low and can be improved through appropriate cultivation technology. The study aims to increase swampland productivity in Tanjung Buka, Tanjung Palas Tengah Sub-District, Bulungan Regency through new superior varieties of rice. The introduction of new superior varieties of swamp rice (inbrida swamp rice-Inpara), namely Inpara-2, 4, 8, Inpari-30, Inpari-32, and local variety as a comparison, with the legowo row planting system (Jarwo) 2:1. The fertilizer dosage was 50 kg NPK ha-1 , 100 Urea kg ha-1 and 1,000 kg dolomite ha-1 . Plant growth, yield components and economic data were observed and calculated. Plant growth and yield components parameter were analyzed with Analysis of Variant (ANOVA), and followed with the Duncan Multiple Range Test (DMRT). Break-even point value and the BCR ratio were calculated for economic analysis. The result showed that the highest rice productivity was Inpara-2 and Inpari-32, and the lowest productivity was local variety. The research results showed that Inpara-2, 4, 8, Inpari-30, and Inpari-32 with the legowo row planting system (Jarwo) 2:1 had BCR >1, whereas if using of local variety BCR <1. Therefore, the recommended varieties to developed in this study area are Inpari-32 and Inpara-2.
