Jaringan irigasi tetes telah banyak digunakan dalam pertanian di Indonesia terutama untuk irigasi di lahan dengan tanaman hortikultura telah terbukti menguntungkan, akan tetapi dalam aplikasi penggunaan system irigasi tersebut untuk pertanian di lingkungan perumahan yang sempit masih diperlukan pengkajian yang lebih spesifik. Studi ini bertujuan untuk mengetahui besarnya angka Reynolds (Re) dan koefisien gesekan pipa (f) yang terjadi pada jaringan pipa distribusi irigasi tetes karena diperkirakan sangat berpengaruh pada aliran irigasi tetes. Uji dilakukan pada 4 variasi muka air tandon dengan data hasil uji yang diperlukan berupa data debit aliran (Q) dan distribusi aliran dari jaringan tiap level jaringan. Hasil studi menunjukkan bahwa Q akan semakin meningkat jika permukaan air di tangki semakin dinaikan, dan debit aliran terbesar diperoleh pada jaringan irigasi di lantai paling bawah. Besar Q pada muka air tangki variasi 4 diperoleh besarnya untuk Q1 = 99,68 cm3/detik, Q2 = 99,22 cm3/detik, Q3 = 93,21 cm3/detik dan Q4 = 66,68 cm3/detik. Besarnya angka Reynolds (Re) aliran yang diperoleh pada lantai 1berkisaran 12.292 – 10.888, pada lantai 2 diperoleh Re2 sebesar 12.495 – 11.477, pada lantai 3 diperoleh Re3 sebesar 12.695 – 12.037 dan Re4 sebesar 12.892-12.572. Jadi pada dimensi pipa yang tetap diperoleh nilai Re yang dihasilkan akan semakin besar jika debitnya ditingkatkan, sedangkan kisaran nilai koefisien gesekan (f) diperoleh sekitar 0,029 sampai 0,031 untuk semua tingkat jaringan irigasi.

Published: September 2024

Wheat is often planted directly after maize in fields following the maize harvest, and maize residues decompose in the soil by various biological factors, releasing phenolic compounds that affect the germination and growth of some crops planted with or after it. This research aimed to identify the effect of Zea mays leaf extract on seed germination physiological and anatomical features of Z. mays var. (Drachma, Mahali) and Triticum aestivum var. (Baraka, Abu Ghraib) . The results showed Z. mays leaf extract stimulated some traits germination (100%) in Drachama at control, plumule length (7.8cm) in Abu-Graib, radicle length (11.6cm) in Baraka at 2%, fresh weight of plumule and radical (0.0113, 0.0148gm) respectively in Drachama at control. There was highest reduction germination (60%) in Drachama at 6% extract [plumule length (1.0)cm, radicle length (4.2cm), fresh weight of plumule (0.0052cm) in Mahali at 4%], fresh weight of radical (0.00026gm) in Abu-Graib at 6%. There was a difference in response in greenhouse experiments. Anatomical traits of the two corn cultivars differed at 2% and 4% concentrations. The highest increase in germination (96.7%) was in Baraka at 4%, shoot length (22.1cm) in Drachama at 4%, fresh weight of root (0.254gm) in Abu-Graib at 4%, [root length (44cm), fresh weight of root (0.052 gm) in Abu-Graib at 4%], the highest reduction in germination (80%) in Abu-Graib, dry weight of root (23gm) in Abu-Graib at 2%. Using HPLC, compounds tannic acid, gallic acid, benzoic acid, and salicylic acid were identified from Z. mays L. extracts. The study will help to develop sustainable agricultural practices, such as crop rotation, to increase crop productivity and reduce reliance on chemicals.

Published: September 2024

This study delineates the mycotoxin-producing capabilities of Rhizopus microsporus strains isolated from stored grains and nuts. Aflatoxins, particularly aflatoxin B1, are significant due to their deleterious effects on human and animal health and their economic impact on vital agricultural commodities. Employing polymerase chain reaction (PCR) for identification, one isolate was confirmed to produce aflatoxin B1 and was associated with R. microsporus. Thin-layer chromatography (TLC) and ammonia gas tests substantiated the isolate’s toxin-producing ability. High-performance liquid chromatography (HPLC) quantified aflatoxin B1 concentration, revealing a yield of 395.19 PPb. This study’s findings are unprecedented, marking the first known instance of such isolates producing toxins globally. DNA extraction from fungal hyphae, PCR analysis, nucleotide sequencing, and submission to the National Center for Biotechnology Information (NCBI) database further corroborated the isolate’s classification as R. microsporus. The isolate was formally registered in the Gene Bank with serial number OP205376.1, representing a notable contribution to Iraqi and international scientific communities.
Synergistic effects of silicon and seaweed extract on growth and leaf nutrient content of papaya cv Red Lady
Authors: Mirza Anis , Tejasree Akkiraju 
Published: September 2024

Silicon is crucial in the process of absorbing and transporting nutrients to the plants, which in turn helps to decrease the toxicity of iron (Fe), aluminium (Al), and manganese (Mn). Plants can better endure drought and salt stress because it strengthens their tissues. Seaweed extracts serve as biostimulants and are considered vital nutrients for sustainable agriculture due to their organic nature and ability to decompose naturally. The present study aimed to compare the nutritional content and growth rate of papaya cv. Red Lady after being treated with silicon and seaweed extract. The papaya plants were moved to new spots 1.5m x 1.5m apart. A Factorial Randomised Block Design with nine treatments and three replications was used for the field experiments. At 6, 7, 8, and 9 months after replanting, silicon (potassium silicate at 0.3% and 0.5%) and seaweed extract at 3% and 5% were made through foliar application. The study showed that the plant's height (278.66 cm), stem width (174.8 cm), number of leaves per plant (33.17), petiole length (127.3 cm), and leaf length (123 cm) were all higher in T8 (SE 5%+PS 0.5%) than in T7 (SE 5%+PS 0.3%) or T5 (SE 3%+PS 0.5%). A study of leaf minerals in synchrony showed that the highest levels of N, P, K, S, Ca, and Mg were found in the leaves nine months after the crop was transplanted. Thus , using modest concentrations of silicon and seaweed extracts topically enhances growth, nutritional content in leaves, and resistance to biotic and abiotic stress, as well as Papaya Ring Spot Virus (PRSV), collar rot, and anthracnose.

Published: September 2024

Antimicrobial resistance has become a major threat to human health globally. One of the reasons for this increase is the abuse and misuse of antibiotics in the poultry industry as a growth promoter. This practice has resulted in the rise of the spread of antimicrobial resistance within the environment as poultry waste is used as manure in the growth of vegetables. With reduced enthusiasm on the part of the pharmaceutical industries to embark on developing new antimicrobial agents in the face of increasing resistance evolution, few options are available in the armamentarium to combat bacterial infections. The study aimed to determine if domestically grown leafy vegetables and soil amended with poultry manure constitute a possible reservoir of antibiotic resistance and assessed their ability to transfer resistance via conjugation experiment. Twenty-seven leafy vegetable samples and poultry manure-enriched soils were collected from some Delta State, Nigeria farms under aseptic conditions. Standard bacteriological methods were used to isolate and identify isolates, then examined for their susceptibility to fifteen antibiotics and potential for resistance transfer via conjugation experiment. Of the 76 bacterial isolates recovered, 52 originated from vegetables, while 24 were from poultry manure-enriched soil. Escherichia coli (14.5%) and Bacillus subtilis (7.9%) were the most prevalent isolates in vegetables and soil, respectively. The antibiotic resistance profiles of the isolates indicated very high resistance levels in Gram-negative isolates obtained from the soil to all tested antibiotics. The resistance profile of Gram-positive isolates from both vegetables and soil showed ≥ 50% resistance in tetracycline. Also, high level of resistance of between 50% to 100% was detected in Bacillus spp. and Enterococcus spp. to erythromycin, tetracycline, and chloramphenicol. Multidrug-resistant (MDR) isolates served as donor cells, while standard Escherichia coli, Pseudomonas aeruginosa, Bacillus spp. and Staphylococcus aureus served as recipient strains. The rate of antibiotic resistance transfer was generally high, particularly for tetracycline (57.1%) and chloramphenicol (61.9%). The high rate of antibiotic resistance transfer observed in this study highlights the risk of MDR spreading through poultry manure use.
Enhancing the biodegradability and environmental impact of microplastics utilizing Eisenia fetida earthworms with treated low-density polyethylene for sustainable plastic management
Authors: Palanna Arpana Pallavi , Sayantan D. 
Published: September 2024

Low-density polyethylene (LDPE) is widely used in food packaging and agricultural mulching, but its disposal generates macro, meso and microplastics that infiltrate the food chain and carry harmful substances. The present study aimed to improve remediation strategies for soils contaminated with LDPE and enhance the survivability of Eisenia fetida. The study dissolved LDPE in trichloroethylene and treated it with starch, hydrogen peroxide, nitric acid and acetic acid, initiating thermo-oxidative reactions. The treatment decreased LDPE's crystallinity index from 48.48% to 44.06% (single treatment), 44.06% to 40.02% (double treatment) and 40.02% to 32.98% (triple treatment), achieving a 15.5% reduction in crystallinity. LDPE microplastics with 40.02% crystallinity showed lower mortality rates in Eisenia fetida earthworms compared to those with 44.06% and 32.98% crystallinity and untreated LDPE. When introduced to E. fetida, microbiota in the earthworm casts included unidentified species from Pseudomonas and Zoopagomycota, known polyethylene degraders. Microbial analysis of treated LDPE microplastics showed changes in gut microbiota, including potential degraders from Aeromonas and Malassezia restricta. XRD (X-ray diffraction techniques analyses) and FTIR(Fourier Transform Infrared Spectroscopy) analyses provided insights into distinct LDPE degradation patterns, identifying hydroxyl and carboxylic groups as functional groups. The study also investigated the ability of altered microflora with treated microplastics to degrade LDPE, favouring decreased earthworm mortality rates. The crystallinity index of treated polyethylene further reduced from 40.02% to 23.58% after 21 days of exposure to E. fetida. This research advances the understanding of oxidised plastics' ecological impacts and will help to develop environmentally sustainable and biodegradable LDPE.

Published: September 2024

Recently, there has been a growing interest in utilizing natural additives in household cleaning products to promote sustainability and reduce chemical usage. Kamias (Averrhoa bilimbi) fruit, known for its acidic properties and potential antimicrobial effects, presents a viable alternative for enhancing the quality and safety of dishwashing liquids. The present study was conducted to utilize Kamias (A. bilimbi) fruit extract as an additive in the production of dishwashing liquid. Physical and microbial tests were performed to ensure the dishwashing liquid's quality, consistency and microbial safety. These tests measured pH, specific gravity, total plate count, Staphylococcus aureus , and Escherichia coli detection. A 4-point Hedonic scale using a modified sensory evaluation tool was used to describe the acceptability of the dishwashing liquid in terms of appearance, fragrance, texture (hand-feel), longevity of suds, degreasing power, and overall quality. The study showed that the appearance ( 3.50), degreasing power ( 3.57), and overall quality ( 3.63) of Kamias fruit extract dishwashing liquid were liked very much. The texture (hand-feel) was interpreted as liked moderately, with a mean value of 3.47. In terms of fragrance ( 3.40) and longevity of suds ( 3.20), the Kamias dishwashing liquid was liked moderately. Data also showed that Kamias dishwashing liquid has a pH (7.00 @ 22.20C) in the neutral range and a specific gravity of 1.0290, which indicates its density relative to water. Furthermore, the detected microbial count demonstrated a significantly low microbial load (<10 Est.) as determined by the total plate count data. The absence of S. aureus and E. coli indicated a hygienic state, increasing the sample's safety quotient across various applications.
Plasposon mutagenesis in Pseudomonas aeruginosa isolates illustrates the role of ABC transporter in intrinsic resistance to antibiotics
Authors: Younis Rafal Mhaide , Faisal Rayan Mazin 
Published: September 2024

Pseudomonas aeruginosa is an opportunist pathogen most commonly related to nosocomial infections. P. aeruginosa infection therapy poses a significant challenge due to its ability to resist various antibiotics currently available. As a result, excessive use of antibiotics during therapy expedites the development of multidrug resistant P. aeruginosa. Hence, this study aimed to identify novel genes involved in multiple antibiotic resistance using plasposon mutagenesis technique. One hundred and ten P. aeruginosa isolates were collected from various clinical sources involving urine, burns and wound’s pus. An antimicrobial susceptibility test was performed to detect their resistance to 18 antibiotics. Results showed that all isolates were resistant to ampicillin and tetracycline, and the highest resistance ras were detected for nitrofurantoin and sulfamethoxazole (99%), followed by amoxiclav, cefotaxime, cefoxitin, ceftriaxone, and kanamycin (98%). While the lowest resistance rate was towards imipenem (49%). Plasposon mutagenesis was used to detect the genes involved in multi-antibiotic resistance. The pTnMod-Gm was introduced to the recipient P. aeruginosa PA4 isolate via triparental mating using E. coli HB101/ pRK2013 as a helper strain. Mutants were screened for resistance defects by plating them on nutrient agar supplemented with different antibiotics. Two mutants were identified; one (M1) exhibited susceptibility to tetracycline, cefotaxime, and ceftazidime, and the other (M9) to ceftazidime and ceftriaxone. The analysis of these mutants revealed the insertion of the plasposon into an open reading frame for the ABC transporter in P. aeruginosa, which plays a distinctive role in extruding antibiotics out of cells.

Published: September 2024

La producción de maní en Argentina se concentra en la región central de la provincia de Córdoba, la cual experimentó últimamente una pérdida importante de la productividad de los suelos y una declinación aleatoria del rendimiento de los cultivos. La contribución relativa de la fijación biológica (FBN) de nitrógeno al maní en suelos de diferente fertilidad no ha sido suficientemente estudiada.Entonces, se evaluó el efecto de cepas de rizobios (TTOO2R, SEMIA 6144R y TAL 1000R) sobre el rendimiento y el balance de nitrógeno de maní cultivado en suelos con alto y bajo contenido del nutriente. No hubo diferencias significativas en los parámetros simbióticos y de rendimiento del cultivo entre las cepas introducidas y las nativas, pero se observó una contribución relativa mayor de la FBN en el suelo con bajo contenido de nitrógeno (~58% de contribución) que en el suelo con alto contenido (~27% de contribución). Esta comprobación del aporte relativo de la FBN asociada a la fertilidad del suelo, no registra antecedentes en la región central de Córdoba y debería recibir mayor consideración en el manejo del cultivo particularmente por su localización actual al sur de la provincia, donde los suelos presentan menores niveles de fertilidad. El rendimiento de maní confitería mostró mayores valores, si bien no significativos, con la inoculación en los 3 años del estudio.
