This research aimed to determine the optimal dosage of biochar and rice straw trichocompost for improving corn plant yield on Ultisol soil. The study was designed using a field experiment method with a Split Plot Design, consisting of two treatment factors. The first treatment factor was biochar with three levels: B0 = without biochar, B1 = 10 tons/ha, and B2 = 15 tons/ha. The second treatment factor was rice straw trichocompost with four levels: K0 = without trichocompost, K1 = 10 tons/ha, K2 = 15 tons/ha, and K3 = 20 tons/ha. The observed parameters for corn plant yield were cob length, cob diameter, dry weight of corn cobs, and dry weight of corn grains. The data collected from the observations were analyzed using an F-test at a significance level of 5%, followed by a Tukey test for further analysis. The results of the research indicated a significant effect of individual treatments of paddy straw biochar and rice straw trichocompost on corn plant yield, but there was no interaction between the treatments on corn yield in Ultisol soil. The optimal dosage of biochar for improving corn plant yield in Ultisol soil was found to be between 10 to 15 tons/ha. Meanwhile, the best dosage of rice straw trichocompost for enhancing corn plant yield in Ultisol soil was between 15 to 20 tons/ha.

The area of rice fields in Indonesia decreased every year. Acid sulfate soil, which was sub-marginal land, had the potential to be converted into rice fields, but it needed improvement, one of which was by using organic materials as ameliorants. This research aimed to obtain the best composition of applying rice harvest residue as an ameliorant on acid sulfate soil in improving the growth and yield of rice. The research was conducted at the greenhouse of Panca Bhakti University Pontianak from January to April 2022. This study used a Completely Randomized Design (CRD). The treatments consisted of: p0: Control, p1: Rice straw = 40 gr/polybag, p2: Rice husk = 40 gr/polybag, p3: Rice husk charcoal = 40 gr/polybag, p4: Rice husk ash = 40 gr/polybag, p5: Rice straw + rice husk, p6: Rice straw + rice husk charcoal, p7: Rice straw + rice husk ash, p8: Rice husk + rice husk charcoal, p9: Rice husk + rice husk ash, p10: Rice husk charcoal + rice husk ash, with each material weighing 20 gr/polybag. The observation variables were plant height, number of tillers, number of productive tillers, dry weight of grains per hill, and 100-grain weight. Analysis of variance used F-test and continued with Least Significant Difference (LSD) test at the 5% level. The application of rice harvest residue had a better effect on the growth and yield of rice than the treatment without the application of rice harvest residue. Treatment p6 had the best effect on the dry weight of grains per hill, which was 65.67 grams. Keywords: Acidic Sulfate Soils, Ameliorant, Rice, Rice husk charcoal, Straw

Celery (Apium graveolens L.) is a horticultural crop that is consumable and offers numerous health benefits. The purpose of this study was to ascertain how celery growth and yield cultivated on alluvial soil were affected by the interaction between liquid organic NPK fertilizer and chicken manure. The study utilized a field experiment that was designed completely randomized comprising two factors. The first factor was the dosage of chicken manure with three levels: C1: 50 g/pot, C2: 100 g/pot, and C3: 150 g/pot. The second factor was liquid organic NPK fertilizer with three levels: L1: 1%, L2: 2%, and L3: 3%. All treatment combinations were performed in triplicates. The results indicated that the interaction between chicken manure and liquid organic NPK fertilizer significantly affected the number of tillers and dry weight of celery yield. Chicken manure as a single factor significantly influenced the number of stems and tillers. Liquid organic NPK fertilizer as a single factor significantly influenced the number of tillers, fresh weight, dry weight, and plant height. The combination of chicken manure and liquid organic NPK fertilizer (C1L3) produced the highest number of stems per clump (79.44 stems) and the highest number of tillers per clump (9.78 tillers). The combination of C2L3 yielded the highest fresh weight (184 g) and dry weight (17.33 g). Keywords: Alluvial soil, Celery, Chicken manure, Liquid organic NPK fertilizer

Peanut production on alluvial soil faced challenges due to low soil fertility. The application of soil amendments such as bioactive compost charcoal (BCC) was necessary to improve alluvial soil fertility. The aim of the study was to assess the effect of rice husk BCC application on the agronomic characteristics of peanut in alluvial soil. The research was conducted using a Completely Randomized Design (CRD) and analyzed using the F-test and Tukey's test at 5% significance level. The study design included 4 samples and 6 treatment levels: d1 (20 g/polybag), d2 (40 g/polybag), d3 (60 g/polybag), d4 (80 g/polybag), d5 (100 g/polybag), and d6 (120 g/polybag). The observation variables included plant height, number of branches, number of pods, pod wet weight per plant, and pod dry weight per plant. The data analysis results showed that the application of BCC had a significant effect on the agronomic characteristics of the peanut plants. The application of BCC at a dose of 120 g/polybag showed the best results and was recommended for use on alluvial soil with crop yield of of 31.72 g fresh pod or 24.86 g dry pod weight. Keywords: Agronomic characteristics, Alluvial soil, Bioactive compost charcoal, Peanut, Rice husk.

Marginal alluvial soils are characterized by low fertility, acidic pH, and limited nutrient availability, which constrain agricultural productivity. This study investigated the effects of goat manure and liquid organic fertilizer (POC) from tofu wastewater on okra growth and yield in alluvial soil. A completely randomized factorial design was employed with two factors: goat manure doses (50, 100, 150 g/polybag) and tofu wastewater POC concentrations (10%, 20%, 30%), each replicated three times, resulting in 27 experimental units. Soil analysis revealed significant improvements in chemical and physical properties after treatment application. Initial soil pH increased from 4.82 to 5.9, organic carbon content rose from 1.82% to 3.05%, total nitrogen increased from 0.16% to 0.42%, and available phosphorus improved from 18.3 ppm to 92.14 ppm. Physical properties also enhanced with bulk density decreasing from 1.62 to 1.24 g/cm³ and total porosity increasing from 34.21% to 46.37%. ANOVA analysis showed significant effects of POC concentration on plant height and fruit weight, with 20% concentration producing optimal results. Goat manure significantly influenced fruit weight, with the highest dose (150 g/polybag) yielding 89.44 g compared to 56.96 g at the lowest dose. No significant interactions were observed between the two factors. The results demonstrate that combined application of goat manure and tofu wastewater POC effectively transforms degraded alluvial soil into fertile growing medium, supporting sustainable okra production in marginal lands.
