Agronomical performance and economic feasibility of new superior rice variety planted on the irrigated field in Jayapura, Papua

Abstract

The study aims to evaluate the agronomical performance of new superior varieties of rice in irrigated fields cultivated through the Integrated Crop Management approach and the feasibility of the farming system. The research was carried out in Koya Barat, a region in District Muara Tami, Jayapura City, Papua Province in April-October 2019. The research used a single factor randomised block design with four new superior rice varieties as treatment afived 5 replications. The varieties were Inpari 36, Inpari 37, Inpari 43, and Ciherang. The data were analysed using analysis of variance (ANOVA) and followed by DMRT to determine the differences between treatments. The R/C ratio, marginal B/C analysis and the break-even point (BEP) were analysed to determine the economic feasibility. The results showed that the performance of each variety varied following their genetic traits. The highest rice production was obtained from Inpari 37 variety (6.86 t/ha), while Ciherang produced the lowest yield (4.34 t/ha). Inpari 37 and Inpari 43 provided higher profit compared to Ciherang and Inpari 36 with R/C values of 3.43 and 3.42, respectively. The highest market acceptance of Inpari 37 was valued at IDR 29,498,000 followed by Inpari 43 at Rp 29,412,000, then Ciherang at IDR 18,662,000 and lastly, the Inpari 36 at IDR 25,542,000. Economically, rice farming is feasible to be developed because it has an R/C ratio of> 1. The irrigated rice farming in Jayapura City is profitable with a rate of around 2.42 % of the total cost spent.
