Abstract
The tidal swampland in Central Kalimantan has the potential as a source of production and as a rice barn. Some obstacles in tidal swampland are high acidity and toxic elements that result in low rice yields. IAARD has several new superior rice varieties that can be used in swampland. However, not all of these varieties can provide high productivity in the same environment. Adaptive and tolerant varieties are needed as well as site-specific cultivation technology. This study aims to obtain adaptive and tolerant rice varieties in the tidal swampland. The adaptation test of several rice varieties was carried out in tidal swampland, Sei Jangkit village, Bataguh sub-district, Kapuas district, and 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 the farming activity is tidal management which includes water management, ameliorant applicant, balanced fertilization, and control of pests and disease. ANOVA was used to determine the effect of varietal treatment on agronomic observation, followed by an average difference test with LSD at a 95% confidence level. Farmers^ preference data were analyzed by Kruskal Wallis and continued with the Mann-Whitney test at the 5% level if there was a significant difference. 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), followed by Baroma (1.51). The Baroma and Inpari-32 varieties are preferred over other types because of the taste of cooked rice, aroma, and color of the rice. These two varieties are close to the rice quality of the local Siam Mayang variety based on farmers^ preferences.
