The current study combined a city land use plan, Geographical Information Systems, and remotely sensed data to evaluate urban spatial patterns within areas where the city plan is reported to have been implemented to support strategic actions for urban environmental sustainability. Focusing on Abuja city, Nigeria, the study deployed a supervised classification on Landsat 8 remotely sensed data to analyze spatial patterns of urban land cover types, computed transition change detections and compared the urban impervious surface to the area of land designated for urban development by the city plan. Key findings indicated that the land areas designated for urban development have not been fully developed and the transition from urban green space is the highest transition from other land cover types to urban impervious surface. The baseline information provided in this study is crucial to inform decision-makers on improving and maintaining the implementation of strategic actions for urban environmental sustainability in Sub-Saharan African cities and other parts of the developing world.","PeriodicalId":314930,"journal":{"name":"International Journal of Multidisciplinary Perspectives","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126301127","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 cultivation procedure is highly sensitive to different environments. In the case of quality production, appropriate seedling age is a prerequisite for higher yield. The experiment was carried out at the Regional Horticulture Research Station, Bangladesh Agricultural Research Institute, Shibpur, Narsingdi, Bangladesh during the Rabi season of 2017-2018. Six treatments were used i.e.,. 14 days, 21 days, 28 days, 35 days, 42 days and 48 days at the age of transplanting seedlings. The experiment was conducted in a randomized complete block design with three replications. The number of seeds per fruit and thousand seeds weights resulted better at 21 days, 28 days and 35 days the age of transplanting seedlings. Considering marketable fruit number (13.55), yield per plant (1.69 kg) and yield (26.80 t ha-1) was found at 28 days’ age of transplant seedling, which was followed by 35 days’ age of transplant seedling. The lowest yield per plant (0.49 kg) and yield (7.76 t ha-1) were recorded at 48 days age of transplant seedling, respectively. From the result of this experiment, it may be recommended that 28 days’ age of seedling at transplant growth, yield and seed production showed better performance than other ages of seedlings at transplants of BARI Mistimorich-1.","PeriodicalId":314930,"journal":{"name":"International Journal of Multidisciplinary Perspectives","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127943890","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}

BRRI dhan28 is influenced by foliar spray of potassium nitrate (KNO3) at four rice growth stages. The experiment consisted of four doses of KNO3 viz. 0 (Control), 0.25, 0.50 and 1.00 kg ha−1 and applied at four growth stages of rice development viz. at panicle initiation, at ear emergence, at anthesis period and at dough stage. This experiment was carried out in Randomized Complete Block Design (RCBD) with three replications with 10 m2 (4.0 m × 2.5 m) unit plot size and spacing between blocks and unit plots was 1 m and 0.5 m, respectively. Results revealed that foliar application of potassium nitrate at four growth stages significantly affected yield and yield contributing characters of BRRI dhan28. But most of the yield contributing characters did not differ significantly due to the interaction between potassium nitrate and stage of foliar spray. However, the foliar application of KNO3 @ 0.25 kg ha−1 showed the highest yield production (5.86 kg ha−1) while the lowest yield (4.85 kg ha−1) was found in control. Furthermore, better yield performances were recorded when the KNO3 was applied at panicle initiation stage rather than the other four growth stages. The total number of tillers, 1000–grain weight and grain yield, was higher with foliar spraying of a 0.25 kg ha−1 KNO3 at panicle initiation stage. From this experiment, it may be concluded that foliar application of KNO3 affected the yield performances of BRRI dhan28 and 0.25 kg ha−1 KNO3 produced the highest grain yield when applied at panicle initiation stage of boro rice.","PeriodicalId":314930,"journal":{"name":"International Journal of Multidisciplinary Perspectives","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129226645","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}
