Abstract

Utilizing idle land as agricultural land is one option that can be pursued to support national food security and independence. Indonesia has various types of alternative food commodities that have the potential to be developed on nutrient-poor land, one of which is hanjeli. Technical cultivation is needed to increase the growth and yield of hanjeli on sub-optimal land. This study aims to determine the best planting distance to increase hanjeli production on idle land. The research was conducted from October 2020 - March 2021 in Limau Manis, Padang City, West Sumatra. The materials used in this study were rice cultivar hanjeli seeds, manure (20 tons/ha) and NPK fertilizer (200 kg/ha). The experimental design used was Randomized Group Design with 3 groups and consisted of 8 plant spacing treatments (40 x 40 cm, 50 x 40 cm, 50 x 50, 50 x 60 cm, 50 x 70 cm, 50 x 80 cm, 50 x 90 cm, and 50 x 100 cm). Observation data were analyzed statistically to determine the influential treatment using the F test at the 5% level and significantly different data were tested using the Duncan’s Multiple Range Test at the 5% level. It was concluded that the spacing of 50 x 70 cm, 50 x 80 cm, 50 x 90 cm and 50 x 100 cm gave the best effect on the number of total tillers/plant, the number of productive tillers/plant, the number of seeds/plant, the percentage of filled seeds, the weight of filled seeds/plant. As for productivity, the spacing of 50 x 80 cm gave the best results.

Abstract

Generally, arbuscular mycorrhizal fungi (AMF) experiment is conducted utilizing sterilized soil. However, the sterilization method would be complicated or impossible to implement in the field application. Therefore, this research aims to investigate whether applying two species of AMF onto oil palm seedling growth planted in non-sterilized soil is still effective. The experiment consists of five treatments, including sterilized media without AMF (T1), sterilized media + FMA Entrophospora sp. (T2), non-sterilized media + FMA Entrophospora sp. (T3), sterilized media + FMA Glomus sp. (T4), and non-sterilized media + FMA Entrophospora sp. (T5). Each of the treatments was repeated four times. The data obtained was tested using analysis of variance and proceeded to the least significant difference test on level alfa 5%. The oil palm seedling was sown in pre-nursery for two months and in the main nursery for three months (the treatment was applied during the transplanting from pre-nursery to the main nursery). The results showed that Entrophospora sp. and Glomus sp. showed a significant result in improving oil palm seedlings’ growth under sterilized and non-sterilized soil with a high root colonization category (>50%). Therefore, both AMF applications are suitable for oil palm plantation fields.

Abstract

Utilization of saline land as an effort to increase rice productivity is still constrained by the adverse effects of salinity stress. The solution to this effort can be done by utilizing PGPR biofertilizers and applying ameliorant briquettes. The purpose of this study was to evaluate the effect of using biofertilizers and ameliorant briquettes on saline soils with various levels of salinity on the growth of rice plants. This research was conducted at the Ciparanje Jatinangor screen house from September 2022 to January 2023. The research design used was a randomized block design with 12 treatments and 3 replications. The treatment applied was PGPR biofertilizer, ameliorant briquettes, and their combination on saline soil 4 and 8 dS m-1 compared to control (non-saline soil). The results showed that PGPR biofertilizer increased the height of rice plants on saline soils 4 and 8 dS m-1 7 DAP. At 14 DAP, PGPR biofertilizer, ameliorant briquettes, and their combinations did not increase rice plant height, root length and volume, wet weight, and dry weight of rice plants, although the application of biofertilizers, ameliorant briquettes, and their combinations tended to increase wet weight and dry weight of rice plant compared to soil with the same salinity without biofertilizers and ameliorant briquettes.

Abstract

Oil Palm Empty Fruit Bunches (OPEFB) have only been used as organic fertilizer by placing it between plants without prior treatment, as a result, the decomposition process of OPEFB takes a long time and produces toxic ammonia. The composting process with variations in composting time and decomposer is a solution in utilizing OPEFB as compost with the best quality. The purpose of this study was to analyze the effect of composting time with Trichoderma sp, Azotobacter, and Palm Oil Mill Effluent (POME) inoculums on the quality of OPEFB compost. The study was structured using a 2-factor Randomized Block Design, which was repeated 3 times. The first factor was the variation of decomposers (Trichoderma sp, Azotobacter, POME) and the second factor is the composting time of 20 days, 40 days and 60 days. The observed parameters including temperature, pH, levels of N, P, K, C, and C/N. The data were statistically analyzed using Analysis of Variance (ANOVA) then further tested with the Least Significant Differences (LSD) test with 95% confidence level if significant effect occured. The treatment gave a significant effect on the levels of N, P and K in OPEFB compost. OPEFB compost had a temperature of 27.33 – 29.33°C, the highest N content was 0.7162%, P content was 0.2222% - 0.8423%, K content was 0.3953% - 0.9043% and C 20.19% - 25.66% which is in accordance with SNI 19-7030-2004 regarding compost quality. The value of the C/N ratio of OPEFB compost products produced from the all treatment was 29.86 – 98.66 so that it did not meet the compost maturity standard of 10 – 20. The production of OPEFB compost can be done with a longer composting time than the treatment in the study, in order to increase maturity value.Keywords: Compost; Composting time; Decomposers; OPEFB

Abstract

Carbofuran insecticide widely used in rice production. The carbofuran residue in agricultural threatens wide life and human health since its active ingredient carbamate is toxic. Humic acid (HA) amendment is an effective way to minimize the residue in soil since HA can adsorb the organic pollutant and induce growth of fungus that degrade the carbofuran. The objective of this research was to observe the influence of HA on the carbofuran residues in soil, straw, and rice; as well as yield of paddy (Oryza sativa L.) grown in carbofuran contaminated potted soil. The level of carbofuran residue in soil before experiment was 10 mg kg-1. The experiment was setup in Randomized Block Design to test various HAs extracted from organic matter. The results indicated that humic acid didn’t affect plant growth and yield but decreased the carbofuran residue in straw and unhusked rice grain. Rhizosphere of rice treated with HA showed higher fungal count than control. This experiment suggests that HA were effectively used to control the carbofuran residue in soil and rice grown in low carbofuran-contamination agricultural soil
