It is one of the most nutritive animal feeds and also can be used by livestock farming communities. Azolla has several times higher levels of crude protein than other forage crops and is also rich in minerals. The aim of the current study is to study growth in various water sources and their quality as supplementary feed to livestock. Methods: A study was conducted in a randomized block design (RBD) with five different treatments and replicated five times to minimize the error. The study was carried out to explore the yield and nutritive value of Azolla pinnata cultivated under different water sources like well water, river water, bore well water, sewage water and drainage water. The duration of the study was three years from Jan 2019 to March 2022. The silpauline plastic bed having dimensions 12 × 4 ft size was used. Every alternate day, the fresh Azolla was harvested and recorded the weight. Result: The pooled data for three years (2019 to 2022) showed a higher yield of 0.31 kg/day of fresh Azolla pinnata in Mula Mutha river water (T2) and 0.30 kg in well water (T1) and sewage water (T4) crude protein content was highest (28.07 %) in sewage water (T4).","PeriodicalId":7599,"journal":{"name":"Agricultural Science Digest – A Research Journal","volume":" 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135290694","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}

Mutations in nature are very few and rare. Ethyl Methane Sulfonate (EMS) is a chemical mutagen that can cause random mutations resulting in changes in genetic material. This study aims to determine the effect of EMS on the germination of soybean (cv. Gepak Kuning) seeds. Methods: The research was conducted at the Faculty of Agriculture Laboratory, Universitas Malikussaleh, Indonesia, in January 2023. The concentrations of EMS used were 0%, 0.025%, 0.05%, 0.1%, 0.25%, 0.5% and 1% with a soaking time of 4 hours. EMS concentration of 0% was used as a control treatment. The observed variables were made as percentage of germination (%) and seedling height at 7th day and 14th day after planting. Result: The results showed that an increase in EMS concentration affected the percentage of germination of soybean (cv. Gepak Kuning) sprouts. A decrease in the percentage of germination was found at an EMS concentration of 0.5%, while a decrease in seedling height had begun to be seen at an EMS concentration of 0.25%. The results of the analysis with CurveExpert 1.4 software showed that the LD50 value of the seeds of soybean (cv.

Sudhakar","doi":"10.18805/ag.d-5816","DOIUrl":"https://doi.org/10.18805/ag.d-5816","url":null,"abstract":"Background: Use of ear punch samples as a competent source of nucleic acids from bovines, gained momentum around two decades ago, as their collection is quite easy and can be transported with minimal quantities of preservatives at ambient conditions. However, the auricular cartilage makes them more resistant to lysis, resulting in poor genomic DNA yields. The objective of the current study was to investigate whether drying can enhance the gDNA yields from ear tissue samples as a few past experiments gave an unanticipated good gDNA yields from completely dried tissue samples. Methods: Upon receipt, ear tissue samples of the cattle and buffaloes were kept at room temperature for different time intervals (in vitro incubation) and then dried at various temperatures prior to gDNA extraction, with commercially available gDNA extraction kits from two manufacturers (MN and QIAGEN). The extracted gDNA samples were assessed with spectrophotometry, flourometry and agarose gel electrophoresis for concentration, purity and integrity. Result: gDNA yields were gradually increasing in parallel to in vitro incubation time till 250 days and after that there was a decline. Further, gDNA yields were significantly higher for ear tissue samples that were not dried prior to extraction, which did not comply with the past experimental observations. Fluorometry-based quantifications revealed that drying of ear tissue samples at greater than 50°C temperatures reduced double-stranded DNA, however up to 50°C the gDNA yield increased, indicating the tissue samples can be safely transported up to 50°C in the TSUs.","PeriodicalId":7599,"journal":{"name":"Agricultural Science Digest – A Research Journal","volume":"41 23","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135819735","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}

Its effectiveness depends on ambient temperature, duration of the treatments and soil moisture. This not only acts as a soil disinfectant but also as soil decontamination. It includes various changes in the soil like physical, chemical and biological properties. Methods: The field to lab and vice-versal based investigations were carried during 2021-2022 at Amity Centre for Biocontrol and Plant Disease Management, Amity University, Uttar Pradesh, Noida and identified tomato nurseries of district G B Nagar where heavy infestation (10-12 J2/cc soil) of root knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood was recorded. The treatments comprised of sustainable components viz. deoiled seed cake of neem, a Arbuscular Mycorrhizal fungus Glomus intraradices and indigenous fungal strain of Trichoderma harzianum, (Th7) alone and together applied for evolving IPM module at solarized and unsolarized sets. Under microplot trials, the entire solarized treatments were carried out measuring 3 × 1 sq. meter each in which one set of all the treatments including control covered with clear transparent polythene sheet (400 ì gauge) for solarization. The treatments were replicated thrice in randomized block design. Result: The observations of solarized and unsolarized treatments clearly revealed that the soil solarization in treatments where the sun radiant energy was trapped by 400 µ transparent polysheets significantly reduced the root knot nematode Meloidogyne incognita population both in root and soil in comparison to unsolarized treatments where no solar energy trapping was done. The combined application of locally isolated Trichoderma harzianum (Th7) and VA mycorrhiza, Glomus intraredices enhanced germination and plant growth in nurseries. In the present investigation, the solarized IPM module- 4 comprising of other sustainable components viz. neem oil-seed cake, T. harzianum (Th-7) and Arbuscular Mycorrhizal (AM) fungus G. intraredices is proved to be an ideal one in root-knot nematode pest management in tomato nurseries.","PeriodicalId":7599,"journal":{"name":"Agricultural Science Digest – A Research Journal","volume":"16 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135321477","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}

Information on SOCs content in coastal lands is scanty and the types of clay minerals and soil fraction size that affect SOCs are still debated. We evaluated the SOCs content and identified the mineral type and soil fraction affecting the SOCs on coastal land. Methods: Soil samples were collected from each layer of nine different soil profiles in three subdistricts: Seunuddon (SD), Lapang (LP) and Dewantara (DT) in Aceh Utara Regency of Indonesia. The soil profiles were taken from different distances (300, 900 and 1500 m from the shoreline-d.f.s). Result: The results revealed that SOCs possessed by each soil layer of coastal land in Aceh Utara varied between 0.64 to 43.45 MgC ha-1. The highest to lowest average total of SOCs content for the location is SD greater than DT greater than LP, while for the position, the distance to the shoreline is 900 m greater than 1500 m greater than 300 m. Clay minerals such as labradorite, smectite, vermiculite and chlorite positively increase the SOCs content.
