Abstract Surface albedo is expressed as the fraction of incoming shortwave solar radiation reflected by the surface. Surface albedo is one of the primary factors influencing regional and global climates as well as ecological and biophysical processes especially in the study of water and energy fluxes of ecosystems. In these research areas, accurate determination of net radiation plays a vital role for determination of the fluxes. In this study, it is aimed to establish the crop albedo values of three sunflower cultivars in the northwestern part of Turkey where sunflower production is represented as country’s production. It can be seen that crop albedo values are related to the crop and meteorological factors like crop phenology, soil moisture etc. Crop albedo also varies by each cultivars of sunflower. Moderate Resolution Imaging Spectroradiometer (MODIS) albedo values and in-situ measurements were compared within this study. In the light of this perspective, albedo is considerably sensitive parameter and has influence on the latent heat flux. Also, comparison between calculated latent heat flux from MODIS data and in-situ measurements were investigated.

Organic agriculture is capable to contribute to the production of healthier food. Organically produced cereals, such as spelt, represent the potential source of quality and healthy components for human food. Spelt wheat is one of the husked hexaploid wheat grown for centuries within a low-input technology. The nutritive value of spelt is high and it contains all the basic components which are necessary for human nutrition. Spelt is high in digestible proteins, vitamins, minerals and antioxidants. Differences may occur due to the growing place and season, cultivation, fertilizers etc. The content of nutritionally important minerals (Fe, Mg, Zn, Ca, Mn) and some antioxidants were analyzed in spelt wheat grown during four different seasons and in semiarid conditions. The spelt wheat was organically grown in the period 2012-2015, at Maize Research Institute Zemun Polje. The crop was sown on the area of 0.33 ha and after harvesting, grain yield was measured from all production area and calculated with 14% of moisture. Then, grains were milled and content of nutrients Mg, Fe, Mn, Ca and Zn, as well as inorganic phosphorus (Pi), phytic phosphorus (P phy ), phenolics, β-carotene and glutathione (GSH), were determined in grains. Obtained data were processed by analysis of variance (ANOVA) and differences with p <0.05 were considered as significant. Among growing seasons, the highest spelt yield was observed in 2012 (4200 kg ha -1 ). The variations in content of minerals and antioxidants followed variations in sum of precipitation, as well as average air temperature. The content of Mg was significantly higher in 2015, while the Ca content was lower. Concentration of Zn and Mn continuously decreased from 2012 to 2015. The highest content of almost all investigated antioxidants was observed mostly in 2013. GSH and β-carotene content variations were also affected by the meteorological conditions of the growing season.
有机农业有助于生产更健康的食品。有机生产的谷物，如斯佩尔特，代表了人类食品质量和健康成分的潜在来源。斯佩尔特小麦是一种脱壳的六倍体小麦，在低投入的技术下种植了几个世纪。斯佩尔特的营养价值很高，它含有人体营养所必需的所有基本成分。斯佩尔特富含可消化的蛋白质、维生素、矿物质和抗氧化剂。由于种植地点和季节、栽培、肥料等原因，可能会出现差异。对不同季节和半干旱条件下生长的小麦进行了营养重要矿物质(铁、镁、锌、钙、锰)和抗氧化剂含量的分析。小麦是在2012-2015年期间有机种植的，由玉米研究所Zemun Polje种植。作物播种面积0.33 ha，收获后在所有产区测量粮食产量，在14%的水分条件下计算粮食产量。然后对籽粒进行碾磨，测定籽粒中营养物质Mg、Fe、Mn、Ca、Zn以及无机磷、植磷、酚类物质、β-胡萝卜素和谷胱甘肽的含量。所得数据进行方差分析(ANOVA)， p <0.05为差异显著。在生长季节中，2012年的斯佩尔特产量最高(4200公斤公顷)。矿物质和抗氧化剂含量的变化随降水总量和平均气温的变化而变化。2015年Mg含量显著升高，Ca含量较低。2012 - 2015年Zn、Mn浓度持续下降。几乎所有抗氧化剂含量最高的年份均为2013年。GSH和β-胡萝卜素含量的变化也受生长季节气象条件的影响。

A pot experiment was conducted to investigate the effects of P and Fe application on the biomass production and nutrients partitioning of two soybeans (Glycine max. L. Merr) cultivars grown in carbonated chernoziom (low in Fe and P) under water stress conditions. P and Fe were applied at two levels (0 and 100 mg P kg-1 soil; 0 and 5 mg Fe kg-1 soil). Control plants were grown at 70% water holding capacity (WHC) while their counterparts were subjected to 35% WHC water stress at initial flowering stage for two weeks. Considerable variability was observed in leaves, roots dry mass accumulation and nodulation among the soybean cultivars (Zodiac, Licurici) at both P and Fe levels in relation to water regimes. The results showed that drought significantly reduced biomass production irrespective of nutrient supply and its adverse effect was more pronounced at low nutrient supply. Leaf development and nodules growth were the most sensitive to water deficit and insufficient nutrient supply. Adequate P and Fe supply increased dry matter production and nutrient concentrations for soybean cultivars. Phosphorus concentration in plant parts was significantly higher at nil Fe compared with Fe application. Phosphorus application decreased Fe allocation to the leaves. The experimental results demonstrated that there was a positive effect of P and Fe adequate nutrition on P use efficiency. Hence, the sufficient phosphorus and iron supply maintained growth at high level, improved P and Fe status and partially alleviated drought effect on soybean plants.
通过盆栽试验，研究了施用磷和铁对2种大豆生物量产量和养分分配的影响。水分胁迫条件下生长在碳酸黑钙土(低铁、低磷)上的L. Merr品种。磷和铁分别施于0和100 mg P kg-1土壤;0和5 mg铁kg-1土壤)。对照植株在70%持水量(WHC)条件下生长，对照植株在35%持水量(WHC)条件下生长2周。在不同的磷和铁水平下，黄豆品种(黄豆品种、利库利奇品种)的叶片、根系干质量积累和结瘤均存在较大的差异。结果表明，无论养分供应如何，干旱都显著降低了生物量产量，且在养分供应不足的情况下，干旱的不利影响更为明显。叶片发育和根瘤生长对水分亏缺和养分供应不足最为敏感。充足的磷和铁供应增加了大豆品种的干物质产量和养分浓度。无铁处理植株各部位磷浓度显著高于无铁处理。施磷降低了铁在叶片中的分配。试验结果表明，磷、铁充足营养对磷利用效率有正向影响。因此，充足的磷和铁供应维持了大豆植株的高水平生长，改善了磷和铁的状态，部分缓解了干旱对大豆植株的影响。

The main goal of the experiment was to study the possibility for biological control of apple scab by use of innovative biofungicide Vacciplant (a.m. Laminarin) and to compare the results of biological control with those from standard chemical control of this disease. Experiment was conducted during the 2016 in region of Prespa and region of Tetovo, on two apple varieties, idared and golden delicious. In untreated variant in region of Tetovo, was observed very high level of infection (77.21% on the leaves and 24.35% on the fruits), which demonstrated the destructive potential of this apple disease in our country. In region of Prespa, significantly lower level of infection was observed in untreated variant (30% on the leaves and 9.5% on the fruits). Regarding the efficacy of tested fungicides, in region of Tetovo, standard fungicide Merpan (a.m. captan) used in chemical variant provided considerably lower degree of efficacy on leaves and fruits (71.38% and 60.86% respectively), compared with biofungicide used in biological variant (95.13% and 94.78% respectively). In region of Prespa, the efficacy performance of standard fungicides on the leaves and fruits (98.33% and 100% respectively) was almost equal with the performance of biofungicide (99.16% and 100%).

Tobacco establishing various ecotypes in different ecological zones is one of the crop plants having high genetic variability. In previous years, tobacco ecotypes were conserved by tobacco farming controlled governmentally. But now tobacco sector is privatized. As a result of privatization, companies in tobacco sector have adopted a few ecotypes based on tobacco farming. This phenomenon has increased the risk of extinction for the present genetic variability and now some cultivars are nearly extinct. In this study, conducted to prevent genetic resource erosion, different tobacco ecotypes were determined by visiting the tobacco fields in Eastern and Southeastern Anatolia Region. Some morphological, technique and yield characters of the cultivars were compared by farming them in field via seed. 12 characters of the cultivars were tabulated. Seeds of cultivars, characters of which were determined were delivered to Seed Gene Bank of Turkey. many fields of the region, different to each other both ecologically and geographically. Broad leaf webby butt and less webby butt types as well as small leaf webby butt types could be encountered in the region and they had been farmed in their own populations. These researchers indicated the presence of Yayladağ, Malatya, Adıyaman, İskenderun, Diyarbakır, Siirt, Mardin, Muş, Bitlis and Şemdinli populations. The mentioned populations were different from those of Aegean, Marmara and Black Sea regions in terms of their physical and blend characters. “Tombeki” and “Hasankeyf” tobaccos of Nicotiana rustica were also present in the region. Ketenci (1985) reported that tobacco was farmed by using the unaccredited seeds and tobaccos having different appearance from different origins were farmed in the same field in Malatya and Adıyaman-Çelikhan 676, a certificated breeding cultivar for the region was degenerated over time and the cultivar could satisfy neither producer nor management in that its yield and quality.
