However, high temperature has significantly retarded the crop growth and yield by alteration of biochemical pathways. Therefore, the biochemical activities of two sugarcane varieties were explored under heat stress condition. The sugarcane cultivars S2003-US-633 (high sucrose accumulation) and SPF-238 (low sucrose accumulation) were cultivated and subjected to different temperature regimes i.e. control at 30±2 °C, heat stress at 45±2 °C and recovery at 30±2 °C for 24, 48 and 72 hours at formative stage. Detailed profiling of physiochemical attributes, sugar analysis linked with sucrose metabolism enzymes and thermotolerance indicators were investigated. S2003-US-633 exhibited better response in terms of sugar accumulation regulated by sucrose synthase, sucrose phosphate synthase and invertase activities along with more proline accumulation, total soluble protein contents with response to high temperature exposure. While S2003-US-633 is ranked as tolerant variety due to less MDA, H 2 O 2 content and electrolytes leakage exhibiting its efficient tolerance mechanism, giving high sugar recovery rate despite harsh environmental conditions. Thus, these findings can be helpful in providing information for engineering sugar improvement along with thermotolerance in sugarcane varieties and providing new avenues towards the economic development of the country.","PeriodicalId":41577,"journal":{"name":"Journal of Agricultural Sciences","volume":"26 1","pages":"78-86"},"PeriodicalIF":0.6,"publicationDate":"2020-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90731480","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}

Thus, the propolis collecting behaviour of honey bee races and ecotypes naturally have been in Turkey, Apis mellifera caucasica, Apis mellifera carnica, Apis mellifera syriaca and Yigilca and Mugla ecotype of Apis mellifera anatoliaca were monitored. The mean yield of annual propolis was recorded as the following; Yigilca ecotype (111.6±27.5 g colony) A. m. caucasica (104±20.7 g colony), Mugla ecotype (103±34 g colony), A. m. carnica (91.16±17.6 g colony), and A. m. syriaca (74±6.4 g colony) in descending order. The highest propolis collecting activity was recorded for the Yigilca ecotype of A. m. anatoliaca and A. m. caucasica. Morphological features of honey bee samples were evaluated by classic morphometric technique to correlate propolis collecting capability and morphological features. Morphometric results of the present study showed that the largest wing and leg lengths belonged to Yigilca ecotype of A. m. anatoliaca and A. m. caucasica. Furthermore, Pearson correlation showed a significant relationship between some morphometric characteristics including the proboscis and mandibular sections, wing length (WL), wing width (WW), femur length (FL), tibia length (TL), basitarsus length (BL), basitarsus width (BW), and propolis collecting capability (P<0.05). Therefore, it seems that the enlargement of certain morphological properties with genetic tendency of the honey bee races and ecotypes, primarily the legs and wings, can lead to better propolis collecting capability.","PeriodicalId":41577,"journal":{"name":"Journal of Agricultural Sciences","volume":"40 Suppl 1 1","pages":"71-77"},"PeriodicalIF":0.6,"publicationDate":"2020-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87295306","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}

In order to reduce energy consumption and increase food flavor quality, modeling the drying process is crucial. In the literature, different approaches are used for investigation of drying characteristic. Among these approaches, the porous media approach have complex phenomena. Molecular diffusion for gases (water vapor and air), capillary diffusion for liquid (water), and convection mechanisms (Darcy flow) were used in drying model in porous media. In this study, firstly, the effect of shrinkage on drying of porous media was investigated. Non-linear partial differential equations for air and food material in the drying problem were solved numerically for non-steady state condition. The shrinkage effect in the drying process was studied by using the ALE (Arbitrary Lagrangian Eulerian) method. In this study, air velocities of 0.5, 0.8 and 1 m s-1, air temperatures of 40, 50 and 60 °C and the geometric forms of rectangular, cylindrical and square were selected for hot air drying process. The fastest drying was obtained at square shape food at the air temperature of 60 °C and the air velocity of 0.5 m s-1. The analysis result showed that the air velocity and temperature have effect on the drying.","PeriodicalId":41577,"journal":{"name":"Journal of Agricultural Sciences","volume":"35 1","pages":"518-529"},"PeriodicalIF":0.6,"publicationDate":"2019-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76362431","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 seed coat color has had a high impact on maintaining germinability for fifteen months. Seeds with darker coat have also shown higher potential for storage and use in subsequent seeding periods, as determined by the application of the aging test on seed.

Since 2000, growers in Turkey have been subsidized and encouraged to increase both their production and quality of forage crops. However, despite all this support and assistance, desired production levels have not yet been achieved. Therefore, it is equally crucial analyze the effects of factors other than the subsidies provided on forage crops production. This study aims to determine the socio-economic factors that affect sustainable forage crops production. The study was carried out in the province of Kayseri, specifically in 11 villages where both plant production and animal husbandry systems are common. The subjects of the study were selected through the Random Sampling Method and data was collected by surveying 310 forage crops growers. To identify dependency relationships between qualitative variables used mainly based on a statistical chi-square statistic. According to the analysis results, 35.5% of growers found forage crops production sustainable, whereas 64.5% of them thought that it was unsustainable. When both socio-economic variables and the answers to survey questions were taken into account, variables such as grower’s age, education level, income level, land for fodder crops, livestock count, recent increase in livestock count, subsidies, and the conditions under which sustainability may be maintained were found to be related to forage crops production sustainability.","PeriodicalId":41577,"journal":{"name":"Journal of Agricultural Sciences","volume":"58 1","pages":"474-480"},"PeriodicalIF":0.6,"publicationDate":"2019-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75197015","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}

Computational Fluid Dynamics (CFD) simulations (numerical method) and direct measurements (experimental method) were used to determine the appropriate indoor environmental conditions. Simulated values were validated by comparison with the measured values using the normalised mean square error (NMSE). The measured and predicted parameters of temperature, relative humidity and air velocity at birds’ height, human height, and roof height upon comparison gave average NMSE values of 0.139, 0.181 and 0.090, respectively. The results showed a good agreement between simulated and measured values as obtained NMSE values were less than 0.25. In conclusion, CFD simulation can be used as an alternative method for the analysis of poultry house indoor environment.
