Appalachian State University, North Carolina (NC), USA, has built a 6.1 m × 9.1 m greenhouse, called the “Nexus” to test the integrated sustainable energy heating system for growing season extension with less energy cost. This is done by using on-farm biomass resources/wastes such as agricultural waste and wood chips to produce energy coupled with solar water heating to store and supplement required thermal inputs. Growing season extension with heated greenhouses increases the availability of local food throughout the year, expands available markets and increases farmers’ profits. Nexus includes an above ground 5,680-L water storage tank and an aquaculture pond. It is supported by a small-scale pyrolysis system, an anaerobic digestion system, solar thermal and compost heating. The preliminary result showed that compared to a conventional space heating system, about 30% of energy was saved to keep the greenhouse temperature available for growing by radiation from the water storage tank. The main purpose of this study was to test the proposed greenhouse heating systems developed at Nexus by implementing pilot systems on two local farms. Pyrolysis and solar thermal system in conjunction with heat storage and delivery system for each farm were built and tested in order to demonstrate how to reduce greenhouse energy use. This paper describes the results of the case study, which showed significant energy savings that can promote the resource-limited farmers’ interest.","PeriodicalId":14977,"journal":{"name":"Journal of agricultural science & technology A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74434658","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 QBG not only focusing on the study of the plants mentioned in the Holy Qur’an and Hadith, but also the endogenous plants of the Flora of Qatar and potential medicinal plants of the Arabic world. In the Hadith, the Prophet’s sayings, there are more than 20 plants mentioned in the occasions of cosmetic or medicinal uses. The garden is conserving special kinds of plants collected from different parts of the world to be restored at one place for preservation and study purposes. Both ex-situ and in-situ conservational programs are designed to collect and conserve plants inside and outside their natural habitats. The QBG plant nursery, herbarium, and seeds units are main components of the QBG that build to produce and preserve the plants at QBG. More than 59 plant spices are preserved from three different geographical zones: desert, Mediterranean and tropical zones. The Garden also is collecting and preserving those traditional entities from the entire world in order to be exhibited in the Botanic Museum of the QBG. By following the Islamic principles of conservation, the QBG highlights these conservational ethics and explains them for all people. Garden emphasizes multi-activities, campaigns, events, fairs and exhibitions for the students and public in order to encourage people to preserve the natural resources through an ordinately oriented educational program which is based on plant conservation. Another side of QBG’s conservation roles is the conservation based on community engagement and education. QBG’s education programs, horticulture and conservation programs, dissemination activities, and partnerships are fundamental in ensuring the transfer of this knowledge to the global community.","PeriodicalId":14977,"journal":{"name":"Journal of agricultural science & technology A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74093514","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}

Creatine level in plasma was increased by CMH supplementation in 46% in EM, 43% in SC and 41% in G. Similarly, concentration of phosphocreatine (PCr) in muscle increased in 84% in EM, 88% in SC and 83% in G, respectively. CMH also improved meat colour L (50.03 vs. 48.88) and reduced drip loss in both EM (5.24% vs. 4.18%) and G (4.48% vs. 3.60%).

Ten quadrats measuring 10 m × 15 m with an interval of 50 m were established from a transect line set up from the baseline to the peak of the landscape. Species of basidiomycetous fungi were pre-identified in the field. Substratum, form, texture, size, color and other noteworthy characteristics were recorded during the time of collection. Confirmation of identities was done using published textbooks, literature and consultation with mycology expert. A total of 863 individuals of basidiomycetous fungi were collected and identified belonging to 19 different families, 31 genera and 53 species. Polyporaceae family has the highest number of species representing 30% of the total number of individuals documented. Most of the species belong to Hexagonia and Polyporus genera. The current research revealed that most of the substrates used by these fungal organisms are woody substrate, specifically rotten woods. The results of Shannon-Wiener diversity index showed that the area has a high basidiomycetous fungal diversity. There was also a high species richness of these fungal organisms, but there was a low dominance and the species were not evenly distributed in the area. As this area is open for hikers, it is recommended that a continuous monitoring of the macrofungi community be done for sustainability and conservation.","PeriodicalId":14977,"journal":{"name":"Journal of agricultural science & technology A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81595004","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}

However, in an urban ecosystem, there are many threats that can affect the assemblages of dragonfly species such as the intensification of urbanization which contributes biodiversity loss of most dragonfly species. This study aimed to identify dragonfly species and determine the species richness, relative abundance, species diversity, evenness and effective number of dragonflies in selected areas in Davao City. Opportunistic sampling using sweep net and photo documentation were used during the study. The sampling lasted for three months from June 2017 to August 2017. A total of 962 individuals of dragonflies were observed and recorded comprising of six species of dragonflies from six different genera of one family. Orthethrum sabina was the most abundant among the six species recorded in all sampling sites. The species richness was six. Low species diversity was obtained in all sampling which shows that the sites were not evenly distributed and indicating that the study sites were not diverse in terms of the number of species and highly disturbed.","PeriodicalId":14977,"journal":{"name":"Journal of agricultural science & technology A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86006581","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}
