Cover crops or crop residue mulching are considered sustainable agricultural measures because they prevent soil degradation and compaction and increase the soil ecological diversity. However, the impact of these on soil quality in fruit orchards in the Vietnamese Mekong Delta is not well studied. The present work aimed to assess the effect of cover crops (grass, pinto peanut) and rice straw mulching on change in soil chemical properties and productivity of pomelo. The 3-year (2019–2021) field experiment was conducted at Phu Huu Commune, Chau Thanh District, Hau Giang Province, Vietnam. Four treatments, control (no-cover crop), grass cover crop, mulching with rice straw (MRS), and pinto peanut cover crop were used. Soil samples were collected from the depth of 0–20 and 20–40 cm for analyzing soil pH, total nitrogen (TN), total phosphorus (TP), available phosphorus (AP), and soil organic matter (SOM). Results showed that MRS or cover crop by pinto peanut significantly decreased soil acidity in the topsoil layer. Soil fertility properties (TN, TP, AP, and SOM) at the depth 0–20 cm were greatly improved after the application of the mulched rice straw and cover crop by legume, thus improving pomelo yield. Further study is required to understand the effects of the cover crop with pinto peanut and rice straw mulching on the physical and biological properties of soil as well as nutrient uptake of pomelo orchards.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67231815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soil bacteria play a significant role in the nutrient cycle of soil, but their presence can be affected by abiotic stress, such as salinity. This study aimed to compare the chemical characteristics of slightly saline and non-saline rice soil and examine the bacterial community structure in both rhizosphere and bulk soil. We utilized 16SrRNA gene sequencing and performed arithmetic means clustering, a type of hierarchical clustering, on the samples collected from the rice fields of Cimrutu and Rawaapu Village in Cilacap Regency, Indonesia. Although the nutrient content was similar in both soils, there was a noticeable difference in their electrical conductivity (EC) despite the two locations being less than 4 km apart. The EC value in the Cimrutu soil suggests that it is non-saline, while the Rawaapu soil exhibits a low salinity level. The study found that Proteobacteria was the most prevalent phylum in saline rhizospheric soil. In contrast, Firmicutes was the most abundant group in saline bulk soil and non-saline rhizospheric and bulk soil. Additionally, Halothiobacillus, Thioalkalispira-Slvurivermis, and Acidothermus genera dominated the saline rhizospheric soil, suggesting that halotolerant microbes play a significant role as plant growth-promoting rhizobacteria in saline soil. The study provides valuable insights into cultured or uncultured bacterial populations and structure in saline and non-saline soil to develop future strategies related to salinity by introducing beneficial microbes.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135802003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a case study approach with qualitative analysis, the study combined primary data from in-depth interviews and secondary data derived from various studies and reports from government organizations. The results show that there is a considerable gap between the government’s fertilizer budget and farmers’ actual needs, leading to coverage of only 37%, thus forcing farmers to purchase more expensive non-subsidized fertilizers. The inefficient distribution system results in delays and scarcity. As a result, there will be market and price dualism between subsidized and non-subsidized markets, as well as subsidized and non-subsidized prices. Enforcement of pricing regulations faces hurdles due to the black market. In addition, farmers use the “foster father” system to obtain credit. To improve fertilizer management, the study recommends a multifaceted approach: increased budget allocation, efficient distribution, strong enforcement of pricing regulations, and innovative financing solutions such as the Tani Card. These strategies, along with improved inter-agency coordination, aim to address challenges and increase the effectiveness of subsidized fertilizer policies.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135662015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Halotolerant rhizobacterial nitrogen fixer (HRNF) was investigated for increasing the nitrogenase activity (NA), organic acid (OA), gibberellic acid (GA), and indole 3-acetic acid (IAA) productions, seedling growth, and rice yield. Six N fixers were isolated using Ashby’s (Ab1, Ab2, and Ab3) and Okon’s media (Az1, Az2, and Az3). Furthermore, bioassay was carried out using rice seedling grown on nitrogen-free medium. The Ab3 and Az2 isolates were selected and biomolecularly identified as Pseudomonas stutzeri and Klebsiella pneumoniae, respectively. These selected bacteria were used as active ingredients for Halotolerant rhizobacterial inoculant (HRI) dosage trials (0, 500, 1,000, and 1,500 g ha−1) on simple pot experiments. The Az group isolates had 3–5 times higher ability in fixing N and producing OA, GA, and IAA than the Ab group isolates. Furthermore, N-uptake, number of panicles, filled grain, and the rice yield of HRI treated pots were significantly increased. Application of 1,000–1,500 g HRI ha−1 had resulted in a significant increase in the yield of rice grain (26.10–28.27 g plant−1 or 15.4–25.09%) which was higher than the control. This result concludes that HRI could contribute in enhancing the ability of rice to adapt and grow under saline stress.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42014981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bacterial pathogen was frequently associated with food-borne origins including seafood. Thus, the present study aimed at screening anti-listeria-producing lactic acid bacteria (AL-LAB) isolated from the intestinal tracts of wild gilt-head seabream (Sparus aurata). Materials and Methods: Lactic acid bacteria (LAB) were isolated from the intestinal tracts of 15 wild gilt-head seabreams and screened for antimicrobial activity against Listeria monocytogenes. LAB isolated with the strongest anti-listerial activity was identified and further characterized for its anti-listerial compounds, followed by testing its protecting capacity on experimentally contaminated salmon fillets. Results: Three out of 52 LAB showed antagonistic activities against the foodborne pathogen. Of these 3, an isolate with the strongest inhibitory activity was obtained from strain MA115 (>400 AU). Based on its 16S rDNA sequence, strain MA115 had 99% similarity to Enterococcus faecium (Acc. Nb: MG461637.1). Further in vitro assays showed that the anti-listerial compound was very sensitive to proteinase K which suggested that it is a bacteriocin-like inhibitory substance (BLIS). In addition, the BLIS was resistant to a wide range of pH (2–10), and low (4 to −20°C) as well as high temperatures (30−121°C). In addition, the BLIS showed bactericidal activity on L. monocytogenes in artificially contaminated Salmon fillets stored at 0°C. Conclusion: The BLIS produced by Enterococcus faecium strain MA115 has the potential for application to improve food safety, although further studies are still required to specifically identify the BLIS, for biopreservation purposes.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45124057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to determine the effects of biofertilizers on dryland improvement and crop production. The study was conducted from February to May 2021 in Central Java, Indonesia. Using a randomized block design in peanut cultivation. Six biofertilizers (Controlled, Agrimeth, BioNutrient, Gliocompost, Agrimeth + BioNutrient, Agrimeth + BioNutrient + Gliocompost) were applied with four replications. The performance of each biofertilizer was assessed based on chemical soil parameters, soil microbe population, plant growth, and yields. The soil in the study area belonged to the Inceptisols group and exhibited moderately acidic pH, low organic carbon content, and low nitrogen levels. However, it had high potential and available phosphorus, as well as moderate potential and high available potassium. BioNutrient and Gliocompost increased available phosphate by 12 and 19%, respectively, due to the presence of Pseudomonas fluorescens and Aspergillus sp. Agrimeth influenced the population of Azospirillum (45–63%) and enhanced phosphate-solubilizing bacteria. Agrimeth + BioNutrient + Gliocompost promoted the growth of the Azospirillum and Trichoderma populations (17–18%), resulting in a 45.04% increase in profits.

However, in this report, pyramiding for multiple traits is presented. We evaluated 28 pyramided rice lines derived from 7 hybridizations of valuable parents for high yield potential, early maturity, aroma, high grain quality, and resistance to brown planthopper using both simple-sequence repeat markers and phenotypic markers. Pyramided rice genotypes were evaluated with RM282 molecular marker linked to GW3 gene associated with grain weight, RM259 (number of panicles), RM3600 (length of panicles), RM3701 (short panicles), RM19414 (Hd3), RM7601 (Hd2), RM190, and SSIIa (waxy), IFAP and ESP (aroma), RM586 (Bph3 and Bph4), and RM8213 (Qpbh4 and Bph17(t)). Eight genotypes (i.e., #9, #15, #16, #22, #25, #26, #27, and #28) were confirmed to have desired genes associated with multiple important traits based on molecular markers and morpho-agronomic traits. A strong correlation was found between RM19414 and heading date, between specific markers for aroma and sensory test. Meanwhile, a weak correlation was found between RM259 with panicle number, RM586, and RM8213 with trichome density. As presented in this study, gene pyramiding promises a new hope to combine multiple traits in rice breeding.
