This study carried out in 2015 and 2016 to determine phenological, pomological and some technological characteristics of 19 seedless mulberry genotypes of the Malatya Apricot Research Institute. Full-bloom periods of the genotypes varied between 27th of April (Poser 24-07) and 3rd of May (24 MRK 02); start of harvest dates varied between 15th of May (Poser 24-07) and 31st of May (Yediveren 24-08); end of harvest dates varied between 5th of July (Angut 009) and 30th of August (Yediveren 24-08). Fruiting durations varied between 50 days (Angut 009) and 95 days (Gemirgap Dutu 24-05). Of the pomological characteristics, average fruit weights varied between 0.77 g (Angut 009) and 2.46 g (Poser 24-07); water soluble dry matter (WSDM) contents varied between 15.50% (Topu Beyaz 1) and 29.60% (Angut 009). Of the technological characteristics, drying efficiency values varied between 15.79% (44 KE 10) and 39.94% (Angut 009), dry fruit color L values varied between 25.97 (Poser 24-07) and 50.20 (İstanbul Dutu 24-12). Based on present findings, Poser 24-07 genotype was found to be prominent with early fruiting and availability for fresh consumption; Yediveren 24-08 genotype with late fruiting; İstanbul Dutu 24-12 genotype with drying efficiency and Gemirgap Dutu 24-05 and Gemirgap Dutu 24-06 genotypes with their longer fruiting durations. Current findings may be beneficial in mulberry breeding programs.

2018
Ahmet Duran Çelik | Erdal Dağıstan
The relationship between an individual’s actual knowledge and their self assessed knowledge about an issue is an important factor on consumer’s behaviour. The effect of the knowledge factor on consumer decision making is evaluated by two approaches which are objective (real knowledge) and subjective (self assessed) knowledge. In certain studies it was found that in some situations consumers believe they know more than they actually do about a topic; and they may make their decisions based upon the knowledge they assume is correct, whether it is true or not. This study aimed at determining the relationship between the objective and subjective knowledge about GM foods of consumers who live in the Hatay city centre. According to the research results; even though around 70% of the consumers thought that their knowledge about GM foods were ‘’enough, or relatively enough’’, correct response ratios of the four questions that were based on specific knowledge were quite low. In other words, consumers were overconfident about their knowledge of GM foods. Also, there was no correlation found between consumer’s purchase intention and knowledge level.

The purpose of this study was to measure and analyse the economic efficiency, and to identify the main factor behind economic efficiency of sorghum and millet for small scale farmers in traditional rainfed sector in North Kordofan State. Primary data is collected using structured questionnaire for a sample of 205 farmers from four localities namely (Sheikan, Umrwaba, Elnuhoud, and Elkhowi). Stochastic frontier approach (cost function) was used to analyse economic efficiency and descriptive statistics were used to analyse socio-economic characteristics of farmers. The results of stochastic frontier cost function revealed that the estimated economic efficiency of the sorghum and millet farmers obtained was found the mean economic efficiency to be 39% and 15%, respectively. The economic efficiency is very weak, because most parameters and inefficiency effect factor found to be not significant, these determinants may give a clear picture of farmers that could be targeted in order to increase efficiency

The aim of this study was to determine the effects of in ovo injection of Saccharomyces cerevisiae (SC) to fertile Ross 308 broiler eggs or dietary supplementation on growth performance, internal organ development, gut histomorphology and cecum microbiota during 14 d of growing period. This study was designed as 2×2 factorial experimental design. Fertile 92 Ross 308 eggs were injected with SC solution 0.2ml at 18d of hatch and 90 eggs non-injected as control, afterward dietary SC supplementation was applied during the 14 d to broiler diet. In this study, 160 broiler chicks were used in four treatment groups at 10 replicate for each treatment group and 4 chicks for each replicates. Treatment groups were A) in ovo SC injection + dietary SC supplementation, B) in ovo SC injection + basal diet, C) no injection + dietary SC supplementation, D) no injection + basal diet as control. Live weight, feed consumption, feed conversion ratio and gut histomorphology, caecum microbiota, internal organ weight were recorded at 14 days of age. Live weight gain increased in C group than in the D group. Feed consumption, feed conversion ratio and internal organ weights were not affected by the treatments. Villi length and villi width increased in A group among the other treatment groups in jejunum, villi length increased in A and C groups among the other groups in ileum. Villi length/villi width ratio increased in A group than in the D group in ileum, was not different in jejunum. LAB counts in caecum were higher in A group than those of C and D groups, but was not different from B group. Enterobactericaea count was lower in A and B group than in the D group, was not different from C group. To conclude, results showed that dietary Saccharomyces cerevisiae supplementation increased broiler growth at 14 day by increasing villi development and improving gut health.
