“…The growth of other food crops, such as soybeans, has also been found to be inhibited due to an excess of Fe (Lapaz et al, 2020). The implementation of ameliorants and the careful selection of tolerant varieties have been scientifically validated as effective strategies to address growth impediments in plants induced by an excessive concentration of Fe (Mahender et al, 2019;Ratmini et al, 2023).…”

Fe stress is a problem in swamp lands that reduces the growth and yield of rice. Providing various types of ameliorants and selecting rice varieties are considered an effort to obtain high rice productivity in tidal land. The research aimed to study the effect of various ameliorants on rice growth and production, and to obtain high productivity of tolerant variety to iron stress at different locations of tidal land. The research was conducted in Karya Bakti Village (1°10'34.8" S and 104°09’31.1” E), Rantau Rasau, East Tanjung Jabung, Jambi. This study adopted a split-plot design with different types and doses of ameliorant as the main plots and several rice varieties as the subplots with three replications. The results showed that the application of ameliorant rice husk ash, coconut husk ash, empty bunch oil palm compost, and goat manure stimulated vegetative and generative growth. Meanwhile, the Inpari 16 Pasundan variety was proven to have better growth and higher production as described through plant height, fresh weight of shoots and roots, dry weight of shoots and roots, root length, number of productive tillers, number of grains per panicle, 1,000 grain weight, and harvested dry grain. The highest rice production was in the Inpari 16 Pasundan variety, 9.3 tons ha-1 (low-Fe) and 7.6 tons ha-1 (high-Fe). The combination of rice husk ash (0.25 tons ha-1) + coconut husk ash (0.25 tons ha-1) + empty bunch oil palm compost (0.75 tons ha-1) + goat manure (0.75 tons ha-1) was the best combination to increase rice productivity. Inpari 16 Pasundan is considered a tolerant variety on tidal land with high-Fe stress. The interaction between ameliorants and varieties was significant on plant height at ages 2 and 4 weeks after planting at low-Fe, number of productive tillers at high-Fe, root length at low-Fe and high-Fe, 1,000-grain weight, and number of grains per panicle at low-Fe, and harvested dry grain at low-Fe and high-Fe.

Iron toxicity is a major problem in increasing rice production in acid-sulfate soils. Humate materials and Silica ions can interact with Fe ions to form chelates so that they can decrease Fe toxicity and increase rice yields. This research aimed to study the effect of humate-silica soil on decreasing Fe toxicity and increasing rice yields in acid-sulfate soils. The research employed a simple randomized block design incorporating treatments F0=100% lime, F1=30% humate manufacturer+30% rice husk ash+40% lime, F2=30% water hyacinth humate+30% rice husk ash+40% lime, F3=30% water hyacinth humate+30% rice husk biochar + 40% lime, F4=30% humate manufacturer+30% rice husk biochar+40% lime, and control=without ameliorant. Each treatment was repeated 4 times. Observations of soil characteristics were carried out at the end vegetative stage including pH and Fe, while at the end of the research, observed including panicle length, 100g weight, and grain weight per pot. The findings indicated that F1 was able to increase pH and decrease Fe2+ concentration and wasn’t significantly different from F3. Ameliorant F3 was able to decrease Fe toxicity and increase rice yields. The application of this formula resulted in a decrease in the usage of agricultural lime while enhancing rice productivity in tidal soil.
