Consumers’ Perception About Genetically Modified Foods and Their Purchase Intention in the City Center of Hatay, Turkey Full text
2016
Ahmet Duran Çelik | Erdal Dağıstan
In this study consumers’ perception of, and purchase intention for genetically modified foods were examined in the city center of Hatay. The data of the 343 surveys were collected by using the face to face interview method. The data were analyzed by means of Likert Scale, and Spearman Correlation Analysis. According to the survey results, consumers’ risk perceptions about genetically modified foods are quite high. Consumers don’t willingly purchase genetically modified foods, and they intend to consume foods grown in traditional methods. High risk perceptions have a determining role on consumers’ views about genetically modified foods and their purchase intention for them. Another outcome from this study is that consumers’ awareness and knowledge levels about genetically modified foods are quite low, and that their perceptions and attitudes are mostly based on biases.

2016
Sayed Mohammad Naim Khalid
Agricultural development is now expected to proceed in a way that maximizes opportunities to improve health and nutrition. Accordingly, the term “nutrition-education-agriculture linkages” describes the set of relationships that shows the mutual dependence of nutrition, education and agriculture. Changes in nutrition or education status are expected to affect agricultural production; conversely changes in the agricultural sector can have significant effects on individual health and nutritional status. Professionals in are trained in nutrition or agriculture, but very few will be trained in both. It is therefore difficult to begin discussions on nutrition-focused agricultural programs and policies. How do we begin to identify these linked outcomes? And how do we begin to think about ways to impact factors that are outside of our sector of expertise? This paper provides a simple framework for thinking critically about nutrition, education and agriculture linkages. The purpose is to help readers identify the linkages of greatest importance to their goals and to begin thinking about how to take steps toward integrating programs more effectively.

This research was carried out to determine the interaction between some bacteria naturally existing in casing soil and Agaricus bisporus (Sylvan Hauser A15) hypha in laboratory (in vitro) and cultivation (in vivo) conditions, and to confirm its effects on mushroom yield. Totally 32 bacteria (3 Gram (+) and 29 Fluorescent Pseudomonads) was isolated from casing soil and healthy sporophores. As a result of in vitro experiment carried out to determine the effects of bacteria on mycelium growth of A. bisporus, 24 bacterial isolates were found more effective at the rate of 2 to 115% than control treatment. To determine the effects of bacterium, chosen at the end of in vitro experiments, on mushroom yield in cultivation conditions, three experiments were established in March, May and July in 2008. At the end of experiments, bacterial isolates provided 8 – 40 % increase in total yield. Population density and change in population number related to time was observed during growing period, after the inoculation of bacterial isolates into casing soil. According to the results, Pseudomonas fluorescens (T 4/2 and Ş 8), P.putida (Ş 2/1 and Ş 10) and Bacillus mycoides (T 7/2) bacterial isolates were colonized successfully both in casing soil and sporophores.

This study was conducted to evaluate the effect of NK chemical fertilizers in combination with compost on the growth and yield attributes of tomato (Lycopersicon esculentum Mill.). The pot experiment was done in a complete randomized block design possessing eight treatments with four replicates. Fruit weight, pulp weight, seed weight, total soluble solid, leaf area and dry weights of plat parts were taken and fruit yield was calculated. All the collected data were subjected to statistical analysis. The results revealed that there were significant differences in fruit and seed weights, total soluble solid, pulp weight, 100 seed weight, pulp consistency, leaf area and crop residue. In these parameters, higher mean values were recorded in chemical fertilizers (7.5 g N + 6 g K2O + 15 g P2O5 per m2) with compost (2 kg per m2) than those in the chemical fertilizers applied alone (9.0 g N + 8 g K2O + 15 g P2O5 per m2as standard control). Total soluble solid and fruit yield were 5.73 obrix and 3.21 kg/m2 respectively in the chemical fertilizers with compost (7.5 g N + 6 g K2O + 15 g P2O5 +2 kg compost per m2) treated plants and these were statically on par with the standard control which gave 4.36 obrix total soluble solid and 3.05 kg/m2 fruit yield. The result could be concluded that application of chemical fertilizers (7.5 g N + 6 g K2O + 15 g P2O5 per m2) with compost (2 kg per m2) could increase the total soluble solid and fruit yield as well as reduce the usage of chemical fertilizers in tomato cultivation over the standard control in sandy regosol.

Antioxidants are naturally occurring substances that combat oxidative damage in biological entities. An antioxidant achieves this by slowing or preventing the oxidation process that can damage cells in the body. It does this by getting oxidized itself in place of the cells. The aim of the present study was to evaluate the in vitro antioxidant and free radical scavenging activities of aqueous and 95% methanol leaf extracts of four herbs viz. Trigonella foenum-graecum L, Murraya koenigii, Coriandrum sativum and Centella asiatica which have frequent use in Indian cuisine. Both aqueous and 95% methanol leaf extracts have shown significant amount reducing power. Both aqueous and 95% methanol leaf extracts of Coriandrum sativum had significant DPPH radical scavenging activity with IC50 value of 0.21± 0.3 mg/L and 0.176 ± 0.008 mg/L respectively. The aqueous leaf extract of Trigonella foenum-graecum L showed low scavenging activity. Among all the leaf extracts, the aqueous leaf extract of Centella asiatica has exhibited significantly high NO radical scavenging activity (80%) with IC50 value of 0.11 ± 0.17 mg/L. The aqueous leaf extracts of the samples have showed significantly high superoxide radical scavenging activity. The activity was maximum for the aqueous leaf extract of Centella asiatica, IC50 value is 4.36 ± 0.41 mg/L. anti lipid peroxide activities were very high ( 90 %) for aqueous leaf extracts of Coriandrum sativum (IC50 = 0.064 ± 0.85 mg/L) and Centella asiatica (IC50 = 0.066 ± 0.9mg/L) at a concentration of 0.16 mg/L. The aqueous leaf extracts of the samples were found to contain large amounts of flavonoids and phenolic compounds and exhibited high antioxidant and free radical scavenging activities. These in vitro assays indicate that these plant extracts are significant source of natural antioxidants which might be helpful in preventing the progress of various oxidative stresses.

Nigeria is one of the countries in sub-Saharan Africa with insufficient food and high food import bill, which have debilitating effects on the productive capacity of the citizens. Maize is the most important cereal after rice and its production contributes immensely to food availability on the tables of many Nigerians. This study examined the contribution of maize production to household food security status of rural maize-farming households in the southern guinea savannah of Oyo state, Nigeria. A multistage sampling procedure was used to select 200 farm households and the data were analysed using descriptive statistics, recommended daily calorie requirement (RDCR) approach, Logit model. Results showed that about three-quarters of the households were food secure and were able to meet the recommended calorie intake of 2260Kcal per capita per day. The shortfall index (P) which measures the extent of deviation from the food security line, indicated that the food secure households exceeded the RDCR by 65%, while the food insecure households fell short of the RDCR by 31%. The logit model showed that maize output, gender, primary occupation of the farmer, farm size and farming experience had a positive influence on food security status while age had a negative influence on the food security status of maize-based farming households in the Southern Guinea Savannah of Oyo State, Nigeria. This suggests need for specific support to improve maize production

Like the whole sub-Sahara Africa, rainfall in Fina reserve is subject of strong inter-annual variability. This paper assesses farmers’ perception on land use utilised in the Fina biosphere reserve and their adaptation measures to climate variability. The statistical methods (descriptive and inferential analysis) are used in this study to determine farmers’ perceptions and the adaptation measures in the Fina reserve. Results reveal that 75.5% of the farmers noticed an increase in temperature and decrease in rainfall ignoring the recent recovery observed in the annual rainfall. The length of rainy season is considered to be shorter according to 77.6% of farmers involved to the investigation. However, all the farmers underlined frequent and longer dry spell. Bush fire is considered by 10.2% of farmers as the major factor affecting the natural resources of the reserve and only about 10% of farmers accorded much importance to agricultural land as contributor to reserve degradation. Most of the farmers are limited by lack of manpower and not by the reserve rule to increase their farmlands. The major adaptation measures are the methods of shifting cultivation and improving seed which are practiced by 51% and 87.8% of farmers, respectively. New adaptation strategies such as adoption of planting pits and stone-bunds for water retention need to be practiced by farmers.

There is a high level of forage deficit in Turkey. It is necessary that cultivation and productivity of forage plant should be increase to close forage deficit in a short time, further, pastures should also be improved. Clover genus involves both annual and perennial species, it has some species are grown different soil conditions. Clover species are grown in cool temperate and humid regions have thin stem and abundant leaf, thus, their hay is very nutritive feed for animals. They can use both increasing forage cultivation and pasture improvement in Black Sea Region.

We evaluated the effect of saw dust ash (SDA) and poultry droppings (PD) on soil physico-chemical properties, soil carbon and nitrogen stock and their effects on the growth and yield of okra (Abelmoshus esculentus) on a typic haplusult in Owerri, Imo State Southeastern Nigeria. The experiment was a factorial experiment consisted of saw dust ash applied at the rates of 0, 5 and 10 t/ha and poultry droppings applied at the rates of 0, 5 and 10 t/ha. The treatments were laid out in a randomized complete block design and replicated four times. Results showed that plots amended with 10 t/ha PD + 10 t/ha SDA significantly reduced soil bulk density from 1.37 – 1.07 g/cm3, increased soil total porosity from 48.4 – 59.7% and the percentage of soil weight that is water (soil gravimetric moisture content) was increased by 68.4%. There were significant improvements on soil chemical properties with plots amended with 10 t/ha PD + 10 t/ha SDA recording the highest values on soil organic carbon, soil total nitrogen and exchangeable bases. Plots amended with 10 t/ha PD + 10 t/ha SDA significantly increased soil carbon stock by 24% and soil nitrogen stock by 49.5% more than other treatments. There was significant increase in the growth of okra when compared to the un-amended soil with application of 10 t/ha PD + 10 t/ha SDA increasing the fresh okra pod yield by 78.5%. Significant positive correlation existed between SCS and organic carbon (r = 0.6128), exchangeable Mg (r= 0.5035), total nitrogen (r = 0.6167) and soil pH (r = 0.5221). SNS correlated positively with organic carbon (r = 0.5834), total nitrogen (r= 0.6101) and soil pH (r = 5150). Therefore applications of these agro-wastes are effective in improving soil properties, increasing soil carbon and nitrogen stock. From the results of the work, application of 10 t/ha PD + 10 t/ha SDA which was the treatment combination that improved soil properties and growth performances of okra than other treatments studied is hereby recommended for soil carbon and nitrogen stock improvement and okra production in the region.
