The study was carried out from November 2021 to July 2022. A total of 164 cases of bladder problems in cats were collected from 3 veterinary hospitals. The results showed that the higher rates of bladder problems in cats occurred in male at 81.71% (female 19.29%), local breed at 63.41% (foreign breed 35.59%), neuterd cat at 64.02% (intact cat 35.98%), commercial food group at 61.59% (mixed diet 38.41%) and free keeping at 54.88% (keep in cage 45.12%). The rates of aged groups (< 2 years, 2-5 years, > 5 years) analyzed by gelded cat and interventional treatment were significantly different (P < 0.05). X-Ray was efficient to diagnose the bladder problems in cats. Results of typical physiological and biochemical indicators associated with the bladder pathology showed that there were increases in white blood cells (29.06 K/µL), monocytes (4.62 K/µL), hemoglobin (27.86 g/dL), aspartate transaminase (73.42 U/L), creatinine (298.53 µmol/L), blood urea nitrogen (20.57 µmol/L) and a decrease in platelets (36.16 K/µL). These blood indicators played an important role in the evaluation of decreased functions of liver and kidneys in the bladder problems of cats.","PeriodicalId":250563,"journal":{"name":"The Journal of Agriculture and Development","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127270363","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 aimed to isolate bacteria that had both phosphate-solubilizing and salt-tolerant abilities for production of controlled-release inorganic fertilizer-incorporated microorganisms. Of twenty-five phosphate solubilizing bacteria strains isolated from soil samples collected from Ho Chi Minh City, Dong Nai, and Long An provinces on Pikovskaya medium (PVK), there were three strains of bacteria that had both phosphate solubilizing activity and salt tolerance. The analysis results on PVK medium supplemented with 3% and 4% NaCl showed that only PSM54 strain had phosphorusdegrading ring. Species identification based on 16S-rRNA sequence showed that PSM54 was 99.9% similar to Bacillus velezensis. The controlled-release fertilizer was made by coating biodegradable polymers incorporated with PSM54 bacteria that met standards for slow dissolution according to The Association of American Plant Food Control Officials. After 60 days of being immobilized in the membrane of controlled release, the PSM54 bacteria remained at 88.3% compared to the initial density.","PeriodicalId":250563,"journal":{"name":"The Journal of Agriculture and Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126819315","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 experiment was conducted in the spring season of 2021 and was a split-plot design with 3 replications. Potassium levels included 0, 60, 80 and 100 kg/ha and phosphorous levels were 0, 70, 90 and 110 kg/ha. The effects of different fertilizer rates were determined through growth and development characteristics (plant height, number of leaves, number of nodes, number of branches), leaf area index, number and weight of nodules, yield components and yield. Results showed that phosphorus and potassium fertilizer application resulted in better plant growth and development than no fertilizer application. Also, the average plant height (47.4 to 50.5 cm), number of branches (2.2 to 2.6), number of nodules in the flowering period (51.2 to 56.3) and yields (1.77 to 1.81 tons/ha) with phosphorus application were better than the plant height (46.1 cm), number of branches (2.0), number of nodules (48.1) and yield (1.74 tons/ha) without phosphorus application. Different levels of fertilization affected the growth and development of VNUAĐ2 variety and its yield. The level of application of potassium (80 kg/ha) and phosphorus (90 kg/ha) significantly increased yield components and yield by 10,1 - 50% as compared with no fertilizer application. When compared with other fertilization levels, the application of potassium (80 kg/ha) and phosphorus (90 kg/ha) resulted in better total pod number of 38.1 pods/plant (30.9 - 36.5% higher), number of filled pods of 36.7 pods/plant (6.70 - 31.5% higher), percentage of 3-seeded pods of 12.9% (6.6 - 29.0% higher), individual yield of 11.42 g/plant (0.53 - 14.1% higher) and yield of 1.86 tons/ha (1.1 - 8.8% higher). Thus, the most suitable fertilizer rate for the soybean variety VNUAĐ2 in the spring season was 80 kg/ha of potassium and 90 kg/ha of phosphorus.","PeriodicalId":250563,"journal":{"name":"The Journal of Agriculture and Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125835448","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}

Two experiments with malabar spinach and mustard greens were arranged in a randomized complete block design with 5 treatments and 3 replications. In ech experiment, the treatments included 5 different spraying concentrations of the foliar solution (0, 2, 3, 4, 5 mL/L per each spray). The number of sprays for malabar spinach and mustard greens was 4 and 2 times, respectively, and the diluted solution for each spray was 1 L/m2. The results showed that the application of these solutions on malabar spinach and mustard greens significantly increased the growth and yield of these two leafy vegetables (P < 0.05). Malabar spinach sprayed with 3 - 5 mL/L per spray had the highest yield (15.38 - 16.70 tons/ha). The greatest yield of mustard greens was achieved with a spraying concentation of less than 3 mL/L (14.67 tons/ha). Malabar spinach and mustard greens sprayed with 3 mL/L gave the best profit margins of 1.24 and 1.59, respectively.","PeriodicalId":250563,"journal":{"name":"The Journal of Agriculture and Development","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126954952","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}
