Abstract

Cultivation technology and the use of new superior varieties are significant in increasing rice productivity in irrigated fields. The study aims to evaluate the agronomical performance of new superior varieties of rice in irrigated fields cultivated through the Integrated Crop Management (PTT) approach and the feasibility of farming revenue. The activity was carried out in Koya Barat, a region in District Muara Tami, Jayapura City, Papua Province on April to Agust 2019. The research design used a single factor randomized block design with 4 new superior varieties of rice as treatment and 5 replications. The varieties used were Inpari 36, Inpari 37, Inpari 43, and Ciherang. Data were analyzed by analysis of variance (ANOVA) and followed by DMRT to determine differences between treatments, while to determine the level of feasibility analyzed using R/C ratio and Marginal B/C analysis and calculating break-even rate (Break event point/BEP) production and price. The results showed that the performance of each variety is varied following their genetic traits. The highest rice production was obtained by Inpari 37 (6.86 t/ha) GKP while the lowest yield was showed in Ciherang (4.34 t/ha). Inpari 37 and Inpari 43 are superior varieties that provide higher profit and highly feasible compared to Ciherang and Inpari 36 with R/ C values of 3.43 and 3.42. The highest acceptance of Inpari 37 was Rp.29,498,000 followed by Inpari 43 variety which was Rp 29,412,000, Ciherang (Rp.18,662,000) and lastly, Inpari 36 (Rp.25,542,000). Economically, rice farming is feasible to be developed because it has an R / C ratio of> 1 and financially irrigated rice farming in Jayapura City is profitable with a profit rate of around 2.42 percent of the total cost spent
