In this study, Common Sage (Salvia officinalis L.) and Anatolian Sage (Salvia fruticosa Mill.) seeds, which are important medicinal plants, were used as plant material. The seeds of the Salvia genus have dormancy as they have seed husks containing a mucilaginous layer. For this reason, in order to improve the germination and emergence performance of seeds and to increase the quality of seeds, nine pre-sowing treatments (KNO3 application, GA3 application, polymer coating, polymer coating + KNO3, polymer coating + GA3, priming, priming + polymer coating, priming + polymer coating + KNO3, priming + polymer coating + GA3) were applied to the seeds and the effect of applications on germination rate, emergency rate, germination speed and emergency speed were investigated.

The aims of this study were to evaluate the traits of reproductive, milking and growth performance of Saanen and Saanen × Hair crossbreds (F1, B1 and B2) raised at the Bandırma Sheep Research Institute. The data were collected from 868 goats for reproductive performance and milk yield and from 1077 kids for survival performance between 2009-2012. Milk components (fat, protein, lactose and non-fat dry matter) of goats (n=162) and body weight changes of kid’s (n=64) were evaluated for one year in 2012. Estrus rates and survival rates were similar among all genotypes. Kidding rate was significantly higher in F1 goats than Saanen goats. Saanen goat had the lowest average mean daily milk yield compared with other genotypes. The effect of year and age were significant on milk yield. Goats in F1 and B1 genotypes had higher milk protein percentage and non-fat dry matter content in comparison with Saanen and B2 genotype. Milk fat and lactose contents were similar among genotypes. Birth weight and monthly live weight were similar between genotypes while weaning weight, six month live weight and yearling live weight were higher in B1 kids in comparison with Saanen kids. The effect of dam age and birth type were significant on birth weight, monthly live weight and weaning weight. The findings related to performance characteristics in goat genotypes investigated show that B1 genotype could be recommend for semi-intensive production system in the Western Anatolia.

Food and nutrition insecurity are inability to access adequate amount of nutritious foods to meet dietary needs for a productive and healthy life. However, food and nutrition insecurity, in some part of Ethiopia, is very high though food is not scarce. Therefore, a survey was conducted to investigate food consumption and dietary habits of the population in the district. A questionnaire and focus group discussions were used for data collection. Data were collected on available food sources and habits of consumption in purposively selected four kebeles in the district. Data were specifically collected on utilization and eating habit of cereal grains, legumes, fruit, vegetables, and animal food sources. A total of 150 representative sample households were interviewed based on the population size of the study area. The result obtained from the survey indicated that cereal grains (34.9%), legumes & pulses (28.5%), fruit & vegetables (16.8%), meat and poultry (19.8%) products are commonly produced in many parts of the study area. The study indicated that the population entirely consumes cereal grains that are mainly sources of carbohydrate, with minimal consumption of other food types. Though there are surplus food items in the study area, there is poor utilization and undiversified consumption habit. This indicates that the area is vulnerable for food and nutrition insecurity. Therefore, knowledge on proper utilization of local existing food sources for enhancing food and nutrition security is essential. Awareness creation on benefits and preparation of balanced diet at household level from local food sources is a vital to improve food and nutrition security in the study area.

The data in this study was provided from 400 households in the Kucukcekmece District of Istanbul Province in 2011. Unclustered Proportional Sampling Method was used to determine the sample size of the study. The primary objective of this study was to identify the most suitable type of milk for consumers. In determining the most appropriate type, four criteria were taken into account. These criteria are hygiene, shelf-life, nutritional content, and price. Based on the data, milk consumption was 30.2 L per annum per capita in Istanbul Province. The households consist of about 3.7 individuals, and they give importance to hygiene by 26.4 percent, shelf-life by 26.7 percent, nutritional content by 29.6 percent and price by 17.2 percent. 55.3 percent of the households prefer UHT (long of shelf-life Tetra Pac packaged milk which heat-treated range of 135-150°C in a short period of 2-4 seconds) milk, 28.5 percent prefer Pasteurized milk, and 16.2 percent prefer Raw milk. Also, while households gave more importance to price and nutrient content at the raw and pasteurized milk, shelf life and hygiene content at UHT milk. Considering these criteria, the most suitable type of milk for the consumers was UHT milk. As a result, the national companies marketing pasteurized milk in the research area need advertisement works that inform the consumers regarding pasteurized milk.

Bu çalışmada makarnalık buğday çeşitlerinde (Levante, Zenit, Yelken 2000, Dumlupınar, Eminbey, Altın, Ç-1252, ve Kızıltan-91) azot dozlarının verim ve kalite özelliklerine etkisi incelenmiştir. Araştırma 2010–2012 yetiştirme sezonunda Isparta ekolojik koşullarında 0, 5, 10 ve 15 kg/da N dozları kullanılarak yürütülmüştür. Çalışma tesadüf blokları deneme deseninde, faktöriyel düzenlemede üç tekerrürlü yürütülmüştür. Fosforun tamamı (6 kg/da P2O5) ve azotun yarısı ekimle birlikte, azotun diğer yarısı kardeşlenme döneminde verilmiştir. İki yılık araştırma sonucunda, azot dozlarının incelenen tüm özelliklere (m2’de başak sayısı, tane verimi, 1000 tane ağırlığı, hektolitre ağırlığı, camsılık ve protein oranı) önemli etkisinin olduğu belirlenmiştir. Ancak azotlu gübrelemenin etkisi çeşitlere göre önemli farklılık göstermiştir. Genel olarak azot miktarının 10 kg/da üzerine çıkarılması, 1000 tane ağırlığı hariç diğer özelliklerde istatistiksel olarak önemli bir artış meydana getirmemiştir. Sonuç olarak, tane verimi ve kalite özellikleri dikkate alındığında, 10 kg/da N dozu ve Çeşit-1252, Altın, Kızıltan-91 ve Dumlupınar çeşitlerinin Isparta koşullarında yetiştiriciliği tavsiye edilebilir.

Crucial point of fishery management is to let the fish or other species reproduce at least once during their life. Therefore it is very important to determine the length at maturity (Lm) for given species before the first capture. Focus of this study is to determine the consistency between scientific results and minimum landing size (MLS) regulations in the marine fishery of Turkey. For this purpose, 4/1 communique on commercial fishery (2016/35) published by the Republic of Turkey Ministry of Agriculture and Forestry was investigated in order to expose the MLS of given species in Turkey. Literature survey on Lm was also conducted preferably on studies which were performed in Turkish waters or from the Mediterranean basin in order to avoid regional differences. While 86 marine species were reported to be landed in the official fishery statistics, only 49 of them were appointed with a MLS in the commercial fisheries regulation. It was determined that MLS of 27 species were below the Lm according to the selected literature, 7 of them require result on Lm, status of the 2 species couldn’t be decided due to different length types and 13 (27% of the decisions on MLS) of them were found to be in accordance with the scientific literature on Lm. This study shows that MLS regulation must be revised for most of the species in the surrounding waters of Turkey and comprehensive maturity studies are urgently needed in order to fulfill the scientific gap.

The aim of this study was to evaluate the chemical composition and mineral bioavailability of T. tetraptera fruit pulp, an aromatic wild edible plant, using standard methods. The pulp were extracted from mature dried fruits obtained from plants at Awabo (5°30’14.2”N and 4°01’30.6”W) and Loviguié villages (5°48’24.5’’N and 4°20’15.8”W), all in south-eastern Côte d’Ivoire. The results of chemical analysis revealed that T. tetraptera fruit pulp contains carbohydrates (63.73±0.51%), crude protein (7.01±0.66%), crude fat (1.18±0.01%), ash (5.38±0.18%), fibre (11.78±0.02%), moisture (40.52±0.18%) and an energy value of 254.74±0.15 kcal/100g. Besides, the results showed a relative high amount of vitamin A (2.11±0.02%) and vitamin B9 (261.78±0.01 µg/100g) while vitamin E, B1 and B2 in trace concentration. Otherwise, the phytochemical analysis (mg/100g) based on dry weight revealed an appreciable amount of total phenol (2407.10±8.36), flavonoids (14.29±0.56), tannins (55.11±0.44), catechin (392.93±1.01) and also carotenoids (108.19±7.42 µg/100g). Organic acids profile (mg/100mL) showed citric acid (175.06±0.02) and salicylic acid (109.85±0.01) as major organic acids. Mineral composition (mg/100g) on dry weight basis revealed that potassium (1303.67±0.58) is the most abundant followed by phosphorus (303.33±5.77), calcium (187.33±0.58) and magnesium (141.33±0.57). Furthermore, the Phytates:Zn, Phytates:Ca, Oxalates:Ca and Phytates*Ca:Zn molar ratios recorded were all below than recommended threshold values, implying a bioavailability of zinc and calcium. These data indicate that the pulp of this fruit could be a good source of ingredient for both medicine and food industries in production.
