The peatlands have the potential to support food security efforts. However, there is have constraints on soil fertility, especially the P nutrients availability. The biotechnology approach, the application of ameliorant (biochar-compost carrier medium (biocom)) enriched with phosphate solubilizing fungi (PSF) and coal fly ash (CFA), was expected to increase the P-availability in peat soils. The research aimed to study the application of biocom enriched with PSF and CFA to increase soil P-availability and plant P-uptake. The study was conducted using peat soil media with the formulation of CFA and biocom enriched with PSF and CFA as treatments. The treatment effect was observed through soil P available and plant P uptake of maize. The results showed PSF application was inconsistent in improving P available in peat soils in Kalimantan. In Central Kalimantan, Biocom + PSF was able to increase P available in peat soils by up to 406.18% (A. oryzae-Tb7) and 353.44% (N. fischeri-Tm8). However, in South Kalimantan P available in peat soil was only 8.04% (A. oryzae-Tb7) and 12.86% (N. fischeri-Tm8). The CFA+ (biocom+PSF) formulation increased P available in Central Kalimantan peat soils, but it was different from South Kalimantan peat soils. The application of biocom+PSF and CFA has not been able to increase the P uptake of maize plant in peatlands of South Kalimantan.

Cultivating of melon particularly in Central Kalimantan has been widely undertaken by farmers, however, the yields have not been able to meet the melon needs of Central Kalimantan's community. One of the breakthroughs in overcoming the problem is by growing melons on swamp floating beds, namely ambul technology. Ambul is growing media from decomposed floating aquatic plants, constructed with bamboo or wooden as a frame, that is let floating on waters. The ambul based on the consideration that the community lacks access to land for most of the year, which reduces opportunities for growing crops. The research design used was Split Plot Design with three kinds of aquatic plants as the main factor namely Eichornia crassipes, Salvinia molesta, Eleocharis palustris, and two melon varieties as subplot factors specifically Action 434 and Amanta. The results showed that the Amanta variety grown on S. molesta media produced the highest value of crop length on 1, 2, 3 weeks after planting (WAP). S. molesta was the best planting media for enhancing flowering by 11.43 days after planting (DAP) and weight of fruit (3.18 kg per plant. The variety of Amanta also had the highest value of root dry weight of 1.33 g per plant and fruit weight of 2.08 kg per plant.

Rorippa indica L. Hiern is a local vegetable that is widely consumed by Dayak’s tribe in Central Kalimantan, Indonesia. It is mostly traditionally cultivated without fertilizers, resulting in low productivity. The research aimed to investigate the effect of fertilizers and soil type on the growth characteristics and N uptake of R. indica. The experiment was arranged in a factorial completely randomized design consisting of two factors with four replications. The first factor was fertilizer application (control, 20 t ha-1 of chicken manure, and 600 kg ha-1 of NPK), and the second was soil type (peat and Ultisol). The results revealed that the interaction of fertilizers and soil type gave a non-significant effect on all variables observed, except N uptake. The application of NPK increased the plant height and number of leaves significantly. Compared to control, the increment was 112.50% and 130.32%, respectively, and chicken manure application increased the dry weight (327.87%), N total (310.16%), and N uptake of plants by 478% in peat soil and 228% in Ultisol. This finding concludes that 20 t ha-1 of chicken manure can be applied to increase the productivity of R. indica.

The synergistic effects of tuber cutting and PGR application on red onion growth and yield have not been extensively studied. Therefore, this study aimed to determine the most effective combination of tuber cutting and plant growth regulator (PGR) application for enhancing red onion growth and yield. Conducted between January and April 2023 in the greenhouse of the Agronomy Department, Faculty of Agriculture, University of Palangka Raya, the experiment utilized a completely randomized design (CRD) with seven treatments, each repeated five times. Treatments included: no cutting, cutting ¼ part of the bulb + 3 mL/L PGR, cutting ¼ part of the bulb + 6 mL/L PGR, cutting ¼ part of the bulb + 9 mL/L PGR, cutting ⅓ part of the bulb + 3 mL/L PGR, cutting ⅓ part of the bulb + 6 mL/L PGR, and cutting ⅓ part of the bulb + 9 mL/L PGR. Results indicate that red onion growth and yield can be significantly optimized through the strategic combination of tuber cutting and PGR application. The treatment involving cutting one-third of the tuber with 6 mL/L PGR concentration yielded the most favorable outcomes. Plants in this treatment displayed an average height of 45.84 cm, 51.4 leaves per plant, 10.6 bulbs per plant, 12.4 tillers per plant, a fresh weight of 42.79 g, a tuber dry weight of 18.34 g, and a bulb diameter of 2.18 cm. These findings suggest that cutting one-third of the bulb, in conjunction with specific PGR concentrations, enhances both yield and nutrient content in red onion bulbs, offering valuable insights for optimizing cultivation practices and maximizing crop productivity.

Degraded peatlands are natural resources that must be managed properly. The unique characteristics of degraded peatlands, such as high acidity and low availability of macro and micronutrients, are the main challenges in soybean cultivation. The pot experiment was conducted using a completely randomized design consisting of four dolomite dosage levels, namely 0, 3, 6, and 9 t/ha, with five replications. The research objective was to assess the effect of dolomite application on the chemical properties of degraded peatland, physiological characteristics, and soybean yield. The results showed that dolomite application significantly improved the chemical properties of degraded peatlands and increased the physiological characteristics and yield of soybeans. Dolomite at a dose of 6 or 9 t/ha achieved the highest pH, exchangeable Ca, and exchangeable Mg after incubation and after harvest. The highest total chlorophyll and average net assimilation rate were obtained at 9 t/ha dolomite application of 3.95 mg/g and 0.048 g/cm2/day, respectively. The relationship between dolomite and the total chlorophyll content of soybean plants was very strong (r = 0.94) with the equation y = 0.35 + 0.37x. The highest soybean seed weight was observed when dolomite was applied at a dose of 9 t/ha, resulting in 9.72 g/plant, an increase of 219.70% compared to the control. These findings suggest that optimal dolomite application can enhance the fertility of degraded peatlands and improve soybean productivity while supporting the sustainable management and rehabilitation of these ecosystems.
