Jordan has paid great attention to its unique heritage of plant biodiversity since the foundation of the country, especially in terms of conservation. Notable conservation efforts have been made by Jordanian governments during the first hundred years of the country's foundation. These efforts were highly fruitful thanks to the unlimited governmental support to all projects related to the conservation of Jordan Flora. So, on the occasion of the first centenary of the country’s foundation, this review article was prepared to highlight some of the efforts made by Jordan during the past hundred years to conserve this national wealth of plant biodiversity.","PeriodicalId":14707,"journal":{"name":"Jordan Journal of Agricultural Sciences","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87904841","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 purpose of this article is to clarify the status of this profession in the country and to trace the developmental activities that have taken place over the past five decades. Currently, there have been remarkable transitions in health attributes among Jordanians as related to nutritional status since fifty years ago. This is manifested in rapid dietary, socio-economic, epidemiologic, and demographic shifts. Accelerated changes have occurred in general health and nutritional status trends, including a decline in the incidence of infectious diseases, increased life expectancy, a surge in all levels of education, rise in urbanization, mechanization and market globalization, decreased physical activity, diets have become denser in energy and richer in carbohydrates, fat, and animal foods. Concordant troubling trends have been recorded for rising morbidity and mortality of major nutrition-related chronic disorders, particularly cardiometabolic risks including diabetes, obesity, cardiovascular disease, dyslipidemia, hypertension, as well as cancer. Consistency with this transition, patterns of nutrition and dietetics profession services have increased steadily. There are 10 public and 17 private universities in Jordan. Six public and five private universities offer degrees in human nutrition. One offers a doctoral degree, four offer a master's degree, and all eleven universities offer bachelor's degrees in human nutrition and/or dietetics or both. In line with these changes, the human nutrition and dietetics profession has gained significant official recognition and legal status permitting certification or licensing and consultation and private practice. However, additional legislative and regulatory attributes, internships and in-service training programs, and national diet manuals are required for such progress to continue at a steady pace. Therefore, there is a need for an official body to shape the landscape of the profession of human nutrition and dietetics in accordance with international standards.","PeriodicalId":14707,"journal":{"name":"Jordan Journal of Agricultural Sciences","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76347379","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 using Nabali olive cultivar in Karak District-Jordan in the year 2016. Three insecticides; Karate, Fytoclean, and Dursban used in the spraying operations, and trees were sprayed twice. Insecticidal spraying significantly (P<0.05) reduced olive oil acidity, peroxide value, and refractive index, and increased olive fruit’s weight, diameter and volume, and seed, and flesh weight compared to the untreated trees.

A. triphylla plants were planted in the University greenhouse (Zahedan) in March. Humic substances solutions were sprinkled onto the soil surrounding the root of the plant. This way of planting simultaneously was repeated in the Zahedan outskirts and Zarand area. In late June, the leaves of planted samples were collected and prepared for senescing through the hydrodistillation method. After collecting leaves and be sprinkled with humic substances solution onto the soil surrounding root of the same plant, the leaves were picked up again in late September for oil extraction. Oil yields (w/w%) of the greenhouse's June samples were 0.45 and 0.48 for the blank and humic samples respectively. By analyzing oils, using GC & GC-MS techniques, 47 and 46 compounds were identified from the blank sample and humic sample oils, constituting 93.21% and 91.58% respectively.

The experiment comprised of three irrigation frequencies IF1: daily, IF2: every other day, and IF3: every 3 days; and five blended water treatments T100(100%TWW), T75(75%TWW and 25%FW), T50(50%TWW and 50%FW), T25(25%TWW and 75%FW), and T0(100%FW), in four replications. Results indicate that the significant effect of the irrigation frequency was mainly on corn cobs yield and consequently crop yield. Crop yield increases as the ratio of TWW increased in the blended irrigation water, with the highest significant yield (58,036 kg/ha) by using pure TWW(T100) and the lowest yield (37,695 kg/ha) was obtained by using FW (T0). Regardless of the irrigation frequency, the highest soil NPK content was obtained by using pure TWW (T100), while the lowest NPK soil content was obtained by using FW treatment (T0). Available soil N, P, and K contents in T100 treatment were significantly higher than that in T0 treatment by 50.4%, 62%, and 53%, respectively. Thus, the use of TWW in agricultural irrigation could provide a good balance of plant nutrients which can markedly increase crop yield and reduced the need for expensive commercial fertilizers.","PeriodicalId":14707,"journal":{"name":"Jordan Journal of Agricultural Sciences","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90112196","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}
