Dose standardization of some common fungicides against Sclerotinia sclerotiorum (Lib.) de Bary

Paper ID- AMA-22-10-2024-13279

Sclerotinia sclerotiorum (Lib.) de Bary is one of the most ubiquitous pathogens affecting a wide range of vegetable crops and brinjal is one amongst the major hosts. The present investigation is carried out for evaluation of the different fungitoxicants under in-vitro conditions against the white rot pathogen. Six fungicides namely Copper oxychloride 50% WP, Metalaxyl 4% + Mancozeb 64% WP, Carbendazim 12% + Mancozeb 63% WP, Carbendazim 50% WP, Mancozeb 75% WP and Propiconazole 25% EC were evaluated at 50, 100, 200 and 500 ppm. The results portray that the mycelial growth was totally inhibited by Carbendazim 12% + Mancozeb 63% WP at 50ppm, 100 ppm, 200 ppm and 500 ppm. Carbendazim 50% WP completely inhibited the mycelial growth at 100 ppm, 200 ppm and 500 ppm, Mancozeb 75% WP at 200 ppm and 500 ppm was at par with Propiconazole 25% EC and Metalaxyl 4% + Mancozeb 64% WP completely inhibited the mycelial growth at 500 ppm. At above mentioned concentrations these fungicides also inhibited sclerotial formation which can be effectively used for control of pathogen in the field conditions by integrating in different disease management practices.

Chemical constituents, antioxidant, anticholinesterase and antimicrobial activities of the essential oil and methanol extract of Centaurea sphaerocephalaL. aerial parts from Algeria.

Paper ID- AMA-20-10-2024-13276

Essential oils were obtained by separate hydrodistillation from arial parts of Centaurea sphaerocephala L. (Compositae). and were analyzed by means of gas chromatography (GC) and gas chromatography–mass spectrometry (GC-MS), The main constituent of the essential oil from the aerial parts was caryophyllene oxide (18.3%), followed by benzaldheyde (16.10%), spathulenol (07.5%), humulene oxide II (07.5%), phenylacetaldehyde (05.3%), and α-terpineol (05.2%). As for the study of the methanol extract and the essential oils of this plant, a multitude of test systems were used, namely: DPPH free radical scavenging assay, CUPRAC cupric reducing antioxidant capacity, β-Carotene-linoleic acid test system and ABTS cation radical scavenging assay. The MeOH extract of aerial parts exhibited a strong antioxidant activity evidenced by the β-carotene-linoleic acid test system, the IC50 values were 43.548± 0.357µg/ml. In the case ABTS cation radical scavenging assay, with the IC50 values were 76.434 ± 2.233 µg/ml, while in the DPPH test the IC50 values were 139± 0.622 µg/ml, while in the CUPRAC test the IC50 values were 159.87 ± 2.03µg/ml,. The essential oil extract of aerial parts showed 09.12 ℅ inhibitory activity against butyrylcholinesterase at 200 µg/mL. The highest antibacterial activity was evidenced for the aerial parts MeOH extracts, with inhibition zone medium diameters of 16.33±1.00 mm against Staphyloccocus aureus ATCC25923 at 16 mg/ml and 14±1.00 mm against Escherichia coli ATCC25922 at 16 mg/ml. This analysis constitutes a pioneer study of composition of the essential oil obtained from the arial parts of Centaurea sphaerocephala L. growing in Algeria.

Bioinformatic Analysis of Perfect Microsatellites SSR Sequences on Chromosome 1A of Triticum aestivum L.

Paper ID- AMA-20-10-2024-13275

Bioinformatic Annotation of Triticum aestivum 1A chromosome from assembled whole genome is not yet complete and lacks participatory contributions to provide more details on its physical map and analyze SSRs (mono-,.. hexanucleotide) statistical distributions. We present, in our work, a script in python language to pre-process the assembled chromosomal sequences and the Krait program for the structural annotation of chromosome 1A to show the possible distributions of all the SSR types as well as the primers likely to be used for PCR sequence amplification. Our results show that the python script is a good tool for genomic data pre-processing. Moreover, the dimeric motifs AG, AT and AC are the most abundant in 1A chromosome and are followed by mononucleotide and trinucleotide SSRs C and AAG respectively. The occurrence of tetra repeats on 1A chromosome is 4219 sequences (72716 bp) corresponding to 8.43% of the total 1A chromosome. The relative abundance and density are respectively 7.15 loci/Mb and 123.16bp/Mb. The highest distribution was observed for the trinucleotide motifs (n = 14,903), characterized by Ra = 25.24 and Rd = 514.94 bp/Mb. Within this category (Trinucleotide), the motifs AAG and AGG were the most dominant with values of 2,987 and 2,431, respectively. The Triticum aestivum 1A chromosome shows all of the SSR types. We observed a polymorphic and unevenly SSRs distribution along the 1A chromosome.

Soybean (Glycine max. (L.) Merrill) Vegetative Growth and Yield Performance under Organic Manures Nutrient Management System in South-Eastern Rajasthan

Paper ID- AMA-19-10-2024-13274

A field experiment was conducted at Research Farm of Agricultural Research Station (Organic Block, field No. 14), Ummedganj, Kota during kharif season 2020 and 2021 on clay loam soil to study the “Soybean (Glycine max. (L.) Merrill) vegetative growth and yield performance under organic manures nutrient management system in South-Eastern Rajasthan” which was laid out in randomized block design with three replications. The experiment comprised of tenth treatments viz. T1 (Control), T2 (100 % OM + 10% CU), T3 (100 % OM + 5% Panchgavya), T4 (75 % OM + 25 % VC + 10% VW), T5 (50 % OM + 50 % VC + 10% VW), T6 (75 % OM + JA 500 L/ha), T7 (75 % OM + GJA 500 kg/ha), T8 (100 % OM + LCB 1250 ml/ha), T9 (75 % OM + LCB 1250 ml/ha), T10 (75 % OM + LCB 1250 ml/ha + 10% SG). In this experiment application of different organic sources were applied to the soybean variety “JS 20-34”. A critical examination of data revealed that significantly higher plant height 45, 60 DAS and at harvest (41.0, 52.6 and 56.1 cm), number of branches/plant 45, 60 DAS and at harvest (5.0, 5.4 and 6.2), total number of nodules/plant at 45 and 55 DAS (46.3 and 44.0), effective nodules/plant at 45 and 55 DAS (41.2 and 34.5), chlorophyll content at 45 and 60 DAS (3.39 and 3.87 mg/g), plant dry weight 45, 60 DAS and at physiological maturity (108.7, 193.0 and 369.7 g/mrl) and crop growth rate 30-45, 45-60 DAS and 60-at physiological maturity (13.90, 16.87 and 17.67 g/m2/day) were observed in application of 50 % OM + 50 % VC + 10% VW over control. Application of 50% OM + 50 %VC + 10% VW was recorded significantly higher number of pods/plant (46.0) number of seeds/pod (2.77), pod length (4.79 cm) and seed index (11.05), seed yield (2160 kg/ha), straw yield (3124 kg/ha) and biological yield (5284 kg/ha) as compared to over rest of treatments. It can be inferred from the economic assessment of data that all the different organic manures treatments recorded significantly higher gross return ( 128172), net return ( 93584), B: C ratio (2.71) and production efficiency (24.55 kg/ha/day) were recorded in application of 50% OM + 50% VC + 10% VW as compared to over rest of treatments.

Ononis angustissima as a Traditional Remedy in four Provinces of South-West Algeria (Ethnobotanical survey)

Paper ID- AMA-19-10-2024-13273

The South-West of Algeria exhibits rich floristic diversity, with many medicinal plants deeply rooted into the healthcare practices of the local population. While ethnobotanical knowledge is important, there are still gaps in the data regarding the use of certain species, such as Ononis angustissima. This study presents the first ethnobotanical survey focused on Ononis angustissima conducted in the provinces of Saida, Namaa, El Bayadh, and Bechar. The primary objective was to document and preserve indigenous knowledge regarding the folk usage of this plant. In this study, semi-structured questionnaires were administered to 172 inhabitants and the collected data were analyzed statistically. Quantitative analysis revealed that the majority of respondents were a married herbalist man (87.2%), mostly older and with limited education including middle school (49.07%). The high frequently treated condition was metabolic disorders, particularly hypercholesterolemia (31.1%), using the dried (62.13%) aerial parts (57.73%), typically prepared as a decoction (75.6%) and administered orally (93.26%). These findings serve as a valuable resource for scientific research and could enrich both national and global pharmacopoeias.
