Abstract

This research was conducted on C-type overflow peatland in Rasau Jaya Dua Village over a period of approximately eight months, from the preparation phase to data analysis. The objective of this study was to evaluate the growth and yield performance of several acid-tolerant maize genotypes and to identify those with potential to be released as new superior varieties. The experiment was arranged in a Randomized Block Design (RBD) with five treatments and five replications. The treatments consisted of five maize genotypes developed through breeding programs: A = F15-1-Bm-2-2; B = F15-1-Cm-2-2; C = F15-1-Dm-2-2; D = F15-1-Em-2-2; and E = F15-1-Fm-2-2. Observed variables included key agronomic traits such as plant height, ear height, days to tasseling and silking, number of rows per ear, ear circumference, ear diameter, number of kernels per row and per ear, ear weight with husks, grain weight per ear, 1000-kernel weight at 14% moisture content, and grain yield per plot. Data were analyzed using analysis of variance (ANOVA). The results showed that genotype D (F15-1-Em-2-2) exhibited the greatest plant height, with an average of 215.94 cm, while genotype C (F15-1-Dm-2-2) had the shortest, at 188.24 cm. The highest yield was achieved by genotype E (F15-1-Fm-2-2), reaching 5.15 tons/ha, whereas genotype C recorded the lowest yield at 3.49 tons/ha. Several genotypes demonstrated promising performance and potential for further development as superior varieties for cultivation on acidic peatland.

Abstract

Sweet corn (Zea mays L.) is a significant upland crop commodity. Peatlands, characterized by nutrient-poor conditions, require soil conditioners for effective sweet corn cultivation. Decanter solid application serves as an alternative to enhance plant nutrient availability. This study aims to evaluate the effect of decanter solid waste on the uptake of nitrogen (N), phosphorus (P), and potassium (K), as well as the yield of sweet corn (Zea mays L.) on Histosols. The research employed a field experiment based on a Completely Randomized Design (CRD) with six treatment levels of decanter solid, ranging from $A_0$ (control) to $A_5$ (1100 g/polybag). Data were analyzed using ANOVA (F-test), followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results indicated that the $A_3$ treatment (700 g/polybag) was the most optimal dose. This dosage significantly increased plant dry weight and the uptake of N and K in the shoots, with increases ranging from 158.59% to 339.3% compared to the control. The application of $A_3$ decanter solid also resulted in a highly significant increase in crop yield, as evidenced by the weight of cobs (both with and without husks), which increased between 437.4% and 770.07% relative to the control. However, this dosage did not significantly improve P uptake in the shoots. The utilization of decanter solid waste at a dose of 700 g/polybag holds great potential for enhancing the growth and yield of sweet corn on Histosols

Abstract

The detrimental ecological impact of unauthorized gold mining in Indonesia is significantly profound, notably apparent in the nutrient-deficient, sandy soils with low pH resulting from the process. These conditions contribute to considerable land productivity decline, especially in West Kalimantan. In response to this challenge, the current study proposes an inventive approach for soil reclamation using red mud residue, derived from bauxite ore extraction, and cow manure as restorative elements. This research delves into a novel soil restoration technique that employs red mud waste (a residual from ore refinement) in conjunction with cow manure as ameliorative agents. A distinct amalgamation of 0.2 kg of red mud and 3 kg of cow manure (T2R3) showcased superior results. The incorporation of this blend resulted in a significant increase in soil pH by 0.93 units, an increase in macronutrient content ranging from 82.84%-503.07%, and plant growth (plant height and stem diameter) increased between 32.85%-54.31% in the treatment with 0.2 kg of red mud and 3 kg of cow manure (T2R3) compared to the lower treatment of 0.1 kg of red mud and 1 kg of cow manure (T1R1). These changes were evident, indicating improved soil fertility and the potential for increased crop yield

Abstract

The high demand for land in various sectors, both agriculture and industry, has encouraged the conversion of peat swamp forest areas. Peat swamp forest clearing through logging and land burning has led to changes in the physical, chemical, and biological properties of peat soils. This study aimed to analyze the impact of land use change on peat soil fertility based on different land use types and to provide fertilizer recommendations for each land use. The research was conducted in Rasau Jaya 2 Village, Kubu Raya Regency. Data were grouped according to land use types to determine the criteria of soil physical and chemical properties. Assessment of soil chemical properties refers to the  BPSITP (2023). The determination of soil fertility status criteria followed the PPT (1995) soil fertility classification for each land use type. Overall, land use change from shrubland to cultivated land at the study site did not significantly affect peat soil fertility. However, increases were observed in several parameters, including base saturation, total phosphorus (P), and total potassium (K) in cultivated land.
