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

Abstract

The demand for chili peppers in Indonesia continues to increase, but in 2021 there was a decrease in chili production. One of the main causes is pathogen attack, especially Ralstonia solanacearum which causes bacterial wilt disease in chili plants. This study aims to evaluate the potential of Streptomyces sp. isolates BMP and TMP to reduce the virulence of R. solanacearum. The research was conducted through a series of laboratory experiments, including an inhibition test with double-layer method and virulence reduction test on Triphenyl Tetrazolium Chloride (TZC) media. The results showed that the TMP isolate was able to produce an inhibition zone of 1.5 cm2 while the BMP isolate showed no inhibition zone. In addition, this study also evaluated the virulence reduction of R. solanacearum due to the treatment of Streptomyces spp. The virulence reduction test showed that TMP isolates were able to reduce virulence by 70% while BMP isolates were able to reduce the virulence of R. solanacearum by 4%. These findings provide new insights into the development of R. solanacearum control strategies. In conclusion, isolates of Streptomyces sp. especially BMP showed potential in reducing the virulence of R. solanacearum, thus providing new hope in efforts to increase chili production sustainably.

Abstract

Acid sulfate soil is a type of suboptimal wetland that has problems including high acidity, low nutrients, and high solubility of Al and Fe. These problems are often overcome by the use of lime and chemical fertilizers, but if we look closely, the unwise use of chemical fertilizers can have a negative impact on the land. The organic farming system through the System of Rice Intensification (SRI) can be an alternative solution for the development of rice cultivation in acid sulfate soils. Therefore, the application of organic matter in the form of compost from agricultural waste (rice straw, coffee grounds, and oyster mushroom baglog waste) is believed to be able to increase the growth and production of rice in acid sulfate soils. The purpose of this study was to determine the potential impact of agricultural waste compost on the growth and production of rice using the SRI method in acid sulfate soils. This research was carried out for six months, from March to September 2021, in Sungai Rangas Village, Martapura Barat District, Banjar Regency, South Kalimantan Province. This research method used a randomized block design (RBD) with 1 factor, namely the type of compost: a0 = without compost application, a1 = rice straw compost, a2 = coffee grounds compost, and a3 = oyster mushroom baglog waste compost. Each treatment consisted of five blocks, so there were 20 experimental units. The results showed that the application of agricultural waste compost has the potential to increase the growth and production of rice using the SRI method on acid sulfate soils. Rice straw compost (a1), coffee grounds compost (a2), and oyster mushroom baglog compost (a3) were able to increase plant height, number of productive tillers, weight of 1,000 grains of rice, and harvested dry grain weight compared to control (a0).
