Adaptation and farmer’s preferences on rice and steamed rice quality of several varieties in Tidal Swampland (case study in Sei Jangkit Village, Central Kalimantan)

Abstract

The tidal swampland has the potential as a production source and a rice barn, but some obstacles are high acidity and toxic elements resulting in low rice yields. To increase productivity, adaptive and tolerant superior rice varieties are needed. This study aims to obtain adaptive and tolerant rice varieties in the tidal swampland, Sei Jangkit village in Central Kalimantan. The activity was carried out from September 2021 to April 2022. The varieties planted, namely, Inpara-2, Inpari-32, Inpari Nutrizinc, and Baroma. They covered an area of 4 ha and involved eight cooperative farmers. The technology applied in farming is tidal management, which includes water management, ameliorant applicant, balanced fertilization, and control of pests and diseases. The results showed that Inpara-2 gave the highest grain yield (5.12 t/ha), Inpari-32 gave 4.48 t/ha, Inpari Nutrizinc 4.58 t/ha, and Baroma 4.98 t/ha. Farming analysis using the B/C ratio of the varieties planted ranges from 1.28 – 1.57, with Inpara-2 giving the highest B/C ratio (1.57). The Baroma and Inpari-32 varieties are preferred over other types. These two varieties are close to the rice quality of the local variety based on farmers’ preferences.
