The present study was conducted in the province of Duhok (Northern Iraq) between 2011-2012. The study attempted to determine the use of certain indigenous and cultivated plants in Duhok province in alternative medicine and place of these plants in systematics. Thus, 49 taxa in 27 genera and 46 species were identified. Two taxa belonged to Coniferophyta, one belonged to Pteridophyta and 46 belonged to Magnoliophyta dividions. It was determined that the family with the most numerous taxa in the region was Rosaceae with 5 taxa, followed by the Fabaceae and Lamiaceae family with 4 taxa and Apiaceae, Asteraceae, Cucurbitaceae and Poaceae family with 3 taxa each. Certain ethnobotanical features of the identified taxa, such as systematics, habitats, flowering times, local names and alternative uses in medicine were presented.

The aim of this review paper is to explore the available information from research findings on the use of Turmeric (Curcuma longa) as a reliable phytogenic antibiotic for poultry production in the tropics especially in Nigeria and other countries. A wide range of phytogenic additives has found a growing interest in fortification of poultry diets. Supplementation of natural alternatives to antibiotic growth promoters in order to maintain both birds’ performance and health in the tropics will be a welcome development. Turmeric has reportedly been widely supplemented in poultry diets as natural alternative antibiotics in several studies with outstanding performances. The nutritional, medicinal, haematological and phyto-toxicological effects of turmeric were reviewed in this paper. Hence, turmeric supplementation at recommended inclusion rate in poultry feeds without posing any deleterious effects to the birds’ performances as well as the consumers of the products, and ultimately, leading to better profitability on the part of the farmers, will be a nutritional breakthrough for the farmers in the tropics.

In this study, the factors affecting on land value in urban sprawl were analysed via regression analysis. In the analyse, the nominal value of land was taken to be dependent variable while factors affecting the value of the land in urban sprawl were considered to be independent variables. 9 factors that were thought to affect the value of the land were handled. In this study, 3 separate models were analyzed, and all models provided statistically significant results. The basic reason for applying three separate models is to be witness the effects by including the variables in different categories (environmental, social amenity and economical factors) separately to the model. As a result of these analyses, all of environmental, amenity and economic factors should be considered for valuation of urban sprawl.

Heracleum platytaenium Boiss. has been used in traditional medicine. Antioxidant effect of essential oil as well as extracts of H. platytaenium was investigated. The essential oil was acquired by hydro distillation using a Clevenger type apparatus and GC-MS was used to analyze the essential oil compounds. Antioxidant capacity including ABTS+•, DPPH• scavenging and reducing power activity tests were carried out for essential oil and extracts. Moreover, total phenolic and total flavonoid contents were investigated. n-Octyl acetate (36.5%), apiole (24.9%), and elemicin (20.8%) were the chief products of essential oil. The essential oil and extracts exhibited from weak to moderate activity. The total phenol varied from 19.01 to 130.99 mg GAE/g extract and total flavonoid was fluctuated from 2.0 to 118.4 mg QE/g extract. The most DPPH• scavenging effect was observed in EtOAc extract (IC50 = 24.09 mg ml –1). The ABTS•+ scavenging effect of EtOAc extract was better than synthetic antioxidants BHA, BHT and Trolox.

In present study, some soil characteristics of Sesamum indicum L. (Sesame) and its adjacent blank field (control) were compared in a growing season as pre (PreC and PreS) and post (PostC and PostS) harvest in Adana, Turkey. Soil macro (C, N, P and K) and micronutrients (Cu, Zn, Mn and Fe), carbon (Cmin) and nitrogen mineralizations and soil aerobic bacteria and fungi counts were determined in before and after harvest soils. Soils were humidified at 80% of their field capacity and then monitored for 45 days at 28 °C to determine soil carbon (Cmin) and nitrogen (Nmin) mineralization. Generally, macro and micronutrients (Cu, Zn, Mn and Fe) were higher in control than sesame field except phosphorus (P2O5) and there were found significant differences between them before and after harvest. Aerobic bacteria and fungi populations were decreased after harvest while fungi populations were increased in sesame soils compared to control. Soil CO2-C evolution was higher in sesame field than control. Rates of carbon mineralization was in order as following PostC < PreC < PostS< PreS. Rate of Nmin was significantly higher in sesame soils before harvest but it was lower after harvest compared to control. Carbon mineralization rates in sesame grown soils were significantly decreased and it was in order as following PostC < PreC < PostS < PreS. Decrease in soil carbon mineralization after harvest can be explained with decrease in soil microbial populations in short term.

Food insecurity in Sub - Saharan Africa (SSA) is on the rise due to soil fertility depletion and in Kenya, Nitrogen (N) is one of the widely deficient nutrients. Biological nitrogen fixation (BNF) can replenish N into the soil system. A study was carried out in acid soils at Koyonzo and Ligala sites of western Kenya to determine the effectiveness of different inoculants after agricultural lime application in enhancing BNF and yields of groundnuts (Arachis hypogea L.) and maize (Zea mays L.) intercrop. Red Valencia groundnut variety was intercropped with Hybrid 513D maize variety. A6w, W1w and V2w indigenous rhizobia strains were tested alongside a commercial rhizobia strain called biofix. Nitrogen treatment was included as a positive control. The results showed that inoculation significantly increased nodule number and weight per plant. There were significant differences among indigenous rhizobia in fixing N. Rhizobia inoculation accounted for 58.91% and 78.95% increase in the amount of N fixed above the control at Koyonzo and Ligala respectively. The strain that fixed the highest amount of N was A6w followed by V2w and W1w at both sites under the dolomitic soil amendment with the values of 14.67, 9.56, 3.53 and 11.37, 8.20 and 1.50 kg N ha-1, respectively at Koyonzo and Ligala sites. Rhizobia inoculation accounted for 80.96% and 47.09% maize yield increase at Koyonzo and Ligala respectively. The best inoculant A6w, gave maize yields of 3.76 and 2.78 t ha-1 at Koyonzo and Ligala, respectively. In conclusion soil amendment with dolomitic lime and inoculating groundnuts with rhizobia strain A6w resulted in increased groundnut and maize yields. This practice can, therefore, be adopted by farmers in western Kenya to improve the productivity of the groundnut maize intercropping systems.

Parametric approaches in statistical analysis assume that any given data are normally distributed. Therefore, the test of whether this conventional assumption is valid should be made in this context of the available data’s normality before being passed to the application of statistical tests. The paper is focused on the normality methodologies commonly used in literature, named Kolmogorov-Smirnov, Jarque-Bera, D’agostino, Anderson Darling, Shapiro-Wilk and Ryan Joiner. In the study, the seasonal maximum data from eight streamflow gauging stations in Yesilirmak Basin was used as material. The normality in the 59% of the whole data sets were obtained as the highest result by the Kolmogorov –Smirnov approach, when compared to the other normality tests considered in the study.

Türkiye’de kırmızı et tüketiminin yaklaşık %90’ını sığır eti oluşturmaktadır. Tüketim bazında ele alındığında sığır eti daha çok dana eti ile eş tutulmakta ve bu nedenle fiyat değerlendirmelerinde dana eti fiyatları yaygın olarak kullanılmaktadır. Dana eti fiyatlarındaki değişimin tüketim üzerinde oldukça etkin bir faktör olduğu bilinmektedir. Bu çalışmada dana eti fiyatlarındaki dalgalanmaların araştırılması amaçlanmıştır. 2005 Ocak- 2017 Aralık dönemini kapsayan süreçte dana eti fiyat belirsizliğinin tespitinde GARCH(1,1) modeli kullanılmıştır. Model sonucuna göre dana eti fiyatlarının ekonomik ve siyasi istikrarsızlık, gıda krizi, doğa olayları vb. herhangi bir şok karşısında büyük sıçramalar ile tepki verdiği ve dana eti fiyatlarının ortalama fiyata göre uzun bir zaman sürecinde normale dönebileceği tespit edilmiştir. Çalışmada, Türkiye’de kırmızı et fiyatlarının istikrarlı bir yapı kazanmasına yönelik dış ticaret politikaları ile birlikte büyükbaş hayvancılığa ilişkin arz politikaları ile tamamlayıcı olarak küçükbaş arzını destekleyici politikaların geliştirilmesi gerektiği sonucuna varılmıştır.

In this study, it was aimed to examine of socio-economic structure of farmers related to organic olive cultivation activity in Gökçeada district of Çanakkale province in Turkey and to determine the knowledge level and approaches towards their organic agriculture. The data of the present study were obtained by survey from 121 farms related to organic olive cultivation determined by using the whole counting method. Data cover the production period in 2016-2017. Descriptive statistics and 5-point Likert-type scale was used to analyse the data. According to the results of study, it was found that the average age of farmers was 53.6 years, the average year of schooling of farmers was 7.5, the average household size was 3.7 persons, the average experience of farmers in organic olive cultivation was also 8.3 years and 10.7% of the farmers had the highest income (50.001₺-60.000₺). Furthermore, the most consciousness level about organic agriculture was determined as ''not use hazardous chemicals for nature and health in organic agriculture'' concept for farmers that make organic olive cultivation. As a result, this study is expected to contribute the development of district's economy and to rural development.

Bu çalışmada, Türkiye’de 2004-2016 yılları arasındaki organik bal üretimdeki değişimler regresyon analizi ile incelenmiştir. Regresyon analizinde, lineer, kuadratik, kübik, logaritmik ve ters regresyon modelleri karşılaştırmalı olarak incelenmiştir. Bu modeller ile elde edilen R2 değerleri sırasıyla; 0,16; 0,62; 0,70; 0,37; 0,52, R ̅^2 değerleri 0,08; 0,54; 0.60; 0.31; 0.48 ve hata kareler ortalaması (HKO) değerleri 48743,01; 24376,61; 21228,61; 36580,48; 27563,47 olarak bulunmuştur. Parametre tahminleri anlamlı bulunan, R ̅^2 değeri en yüksek ve HKO değeri en düşük olan kuadratik regresyon modeli en uygun model olmuştur. Bu regresyon modeline göre, 2017 ve 2018 yıllarında organik bal üretim miktarının sırasıyla; 693 ve 891 ton olacağı tahmin edilmiştir. Ayrıca, aynı dönem içinde organik olmayan bal üretiminin regresyon analizi de yapılmış ve lineer regresyon modeli en uygun model olarak belirlenmiştir. Bu model için R2=0,77 ve R ̅^2=0,75 olarak hesaplanmıştır. Sonuç olarak, organik ve organik olmayan bal üretim miktarlarının farklı regresyon modelleri ile tahmin edilebileceği kanısına varılmıştır.
