Santosh Raj Tripathi | Jiban Shrestha | Jagat Devi Ranjit | Reshma Neupane
Soybean (Glycine max L. Merril) is widely grown in the mid hills as intercrop with maize or in paddy bunds, while it is gaining popularity as sole crop in terai and inner terai. Mean temperature at Khumaltar during soybean growing period was mostly fluctuating; but we observed an increasing trend in temperature. Amount of rainfall was not changed dramatically but number of rainy days was decreased during study period. Rainfall during germination time increase soil moisture which also increase germination and found higher early stand. Days from sowing to 50% flowering and 90% maturity were short in the case of higher minimum temperature and low rainfall. Among the genotypes, AGS-377, AGS-378, AGS-379 and Tarkari Bhattmas-1 were more sensitive. However, seed yield decreased in the case of higher temperatures and low rainfall. Cool night temperatures and high moisture increased disease incidence in soybean which, eventually reduced yield. In last three years, plant suffered from moisture stress during early vegetative stage and high moisture during late vegetative stage which reduced seed yield and seed weight. In conclusion, we found that genotypes like AGS- 360, Sathiya and Tarkari Bhatmas-1 are very sensitive to climatic variation.

Mohamed Ahmida | Akram Elshebli | Ahmed Elzigl | Elmutazbellah Siddek
In Libya especially in Benghazi, Zummita is a traditional Libyan food consisting of 85% whole barley flour and is commonly consumed as a breakfast meal, and. Due to an increase in Type 2 diabetes and a lack of information on the effects of Zummita consumption on glycemic response, this study was performed to determine the glycemic index (GI) of Zummita. Fasted healthy subjects (6 males and 6 females) volunteered to consume either glucose or Zummita. The blood glucose concentrations were analyzed using capillary blood samples immediately before, 30, 60, 90 and 120 min after glucose or Zummita consumption. The GI value of Zummita was calculated by expressing the incremental area under the blood glucose response curve (IAUC) value for Zummita as a percentage of each subject’s average IAUC value for the glucose. The GI value of Zummita was found as 46.90 ± 7.56. This result indicates that Zummita should be classified as low GI food. More importantly, our result provides the GI value of a Libyan traditional food which was not determined previously. This valuable information will be significant for management and the prevention of diabetes mellitus in Libya and other countries having similar food tradition.

Lin, Jin-Feng | Minarsch, Eva-Maria | Ishiguro, Munehide | Uchida, François Yoshitaka
In natural farming rice paddies, intertillage (tillage between rows, during rice growth period) is often performed mainly to remove weeds without the use of chemicals. Also, the intertillage disturbs soil surfaces, potentially impacting the characteristics of soil microbial communities, such as their diversity and abundance. Natural farming systems aim to maintain biodiversity, but it remains unclear whether the intertillage impacts soil microbes in rice paddies. Thus, this study aimed to understand to what extent “five times intertillage” treatment (5T) influences soil bacterial abundance and community structures compared with no tillage (NT), under a natural farming rice paddy system. Soils were sampled at rice proximity, soil surface, and 10 cm depth in a natural farming rice paddy, during the early to late vegetative phase (June to July), in Hokkaido, Japan. The 16S rRNA community structures and abundance were analyzed by next generation sequencing (NGS) and quantitative PCR, respectively. We observed that NT had significantly higher bacterial abundances at the soil surface than 5T. However, there were no clear differences between 5T and NT, regarding the bacterial community structures, including their diversity indices. Instead, the sampling timings markedly impacted the bacterial community structures for the rice proximity and soil surface, showing increasing diversity indices at the late vegetative stage, compared to the early vegetative stage, suggesting the interaction between the crop growth and bacterial communities. In this study, we did not observe the significant difference between the rice yield from NT (2.3 ± 0.7 t·ha⁻¹) and 5T plots (2.7 ± 0.9 t·ha⁻¹); however, the 5T might have negatively impacted soil bacterial abundances but not the community structure of the bacteria.

Özgür Kıvılcım Kılınç
The symptoms which were directly bound to the biochemical mode of action of an herbicide, other symptoms result from an indirect consequence of this action. The symptoms of herbicidal action deeply differed and that the climatic factors during the two first weeks after treatment could change definitely the result of the selective herbicide action. The repetitive observation of symptoms allows to inform the farmer about the tolerance or resistance of certain plant species, including the culture, for instance through the appearance of symptoms on the first leaves of the seedlings and their absence in the following leaves. As a whole, the accurate observation of herbicidal symptoms on plants is the essential, rapid and non-expensive analysis of treatment effectiveness at the field scale. The purpose of the current report is to describe the symptoms of a very complex herbicidal action, that of aclonifen involving two modes of action for the same molecule, approximately at the same concentration, and to compare these symptoms under field conditions and under controlled conditions, for a better understanding.

The aim of this study is to develop salad dressing as an excipient food that can be used to enhance beneficial effects of salads when co-ingested together. The compounds that include bioactive constituents different from other salad dressings are germinated seed and sprouts of lentils and cowpeas, and caseinomacropeptide isolated from whey. The proximate composition, total phenols and total flavonoids of salad dressing were determined. Its beneficial effects on health (antioxidant activity, antidiabetic activity, bile acid binding capacity, and angiotensin converting enzyme inhibitory activity) were determined using in vitro methods. Energy value of salad dressing is 111 kcal/100 g and 11.41% of the energy value of the salad dressing is provided by protein. Total phenol content is 79 mg CE/100 g. Salad dressing displayed higher antioxidant activity against DPPH radical (130 mM Trolox/100 g) than that of ORAC value (72 mM Trolox/100 g). Salad dressing inhibited ACE by approximately 37%. Expected glycemic index of salad dressing was 74.0 and belongs to high glycemic index foods. Contrary to, salad dressing inhibited α-glucosidase and α-amylase with the IC50 values 1.77 mg protein/mL and 2.40 mg protein/mL, respectively. Relative to cholestyramine, bile acid binding capacity of salad dressing is 39.85%.

The main objective of this study is to investigate the consumption behaviour and consumption awareness of energy drink among university students. Data were collected from 750 students in Afyon Kocatepe University by questionnaire which is improved by writers of this article. Tests were done with SPSS end of the research. Chi-square tests were done in %95 confidence interval to determine the relation of consumption and awareness of energy drink among the university students with gender, age range, school which is graduated, monthly expense, smoking and use of alcohol, the most consumed beverage types, and degree of licence. According to search results, it was found that energy drink consumption behaviour did not change with regard to the different age. On the other hand, male college graduates compared to other types of high school, it was determined that 701 TL per month and over spenders in relation to the lower income groups consumed more energy drinks . In addition, it was found that the groups that use alcohol, smokers, coffee drinkers and undergraduate students were consumed much more energy drinks than the others. When the answers measured the energy drink consumption behaviour of the students participated in the survey were considered, it was concluded that the awareness of the energy drink consumption was not high enough.

This study evaluated the correlation between scrotal circumference (SC), body weight (BW) and body condition score (BCS) in relation to breeding age in West African Dwarf (WAD) bucks. A total of 320 WAD bucks from birth to 15 months of age from various farms in Ibadan, Nigeria, were studied. They were grouped as A-birth to 3, B-4 to 7, C-8 to 11 and D-12 to 15 months old respectively, comprising of 80 bucks per group. Semen was collected from 10 randomly selected bucks in each group and analysed. Results showed positive correlation between SC and age; SC increased with age; and at about 8 months of age and over, a consistent SC of 17 cm–18 cm was observed. BW also increased with age; BW significantly affected SC. Also, at 8 months of age and over, SC of 17 cm-18 cm was observed from 9 kg BW and above. However, the correlation between SC and BCS was low and not significant. Semen analysis revealed the best semen quality for groups C and D bucks. In conclusion, we suggest that WAD bucks of 8 months and above, with at least SC between 17 cm–18 cm and of over 9 kg BW, could be used to breed does successfully on the farm.

Sevgi Durna Daştan | Yusuf Muhammed Durna | Taner Daştan
Phenylthiocarbamide (PTC) is known as phenylthiourea and it is an organic compound that has the phenyl ring. Ability to perceive the tastes of PTC chemical is related to the dominance of taste genes. There are a large number of population studies regarding the PTC taste perception and different personal characteristics or disease conditions. The purpose of this study is to reveal and compare the relation between the PTC taste perception and work-out habits, smoking, alcohol consumption and tendency to the depression of people. A total of 2500 adults were volunteered to be included in this study. PTC taste perception was measured by tasting with PTC solution (10 mg/L) filtered in a paper. It showed that tasters were significantly more frequent (81.8%) than nontasters (18.2%) in all population. And in some parameters analyzed in this study, there are significant differences. The taste genetics show up with environmental factors and create the sense of taste, which develops the feeding behaviors. The taste perception resulting from food and beverages diversifies by genetic and environmental effects and the nervous system interprets this perception. This study is enlightening in terms of presenting that the taste perception of people affects their lifestyles and lead them to start and either continue or discontinue some habits.

Sustainable marketing is a holistic approach that puts equal emphasis on environmental, social equity, and economic concerns in the development of marketing strategies. The purpose of the study is to examine and discuss the sustainable agricultural marketing initiatives practiced throughout the World and Turkey, and to put forth suggestions to further improve the performance of agricultural marketing initiatives in Turkey. Some of the sustainable agricultural marketing initiatives practiced around the world are carried out through civil organizations. Furthermore; some of these initiatives have also launched by farmers, consumers, food processors and retailers. The long-term strategies to increase these initiatives should be determined due to the fact that examples of successful sustainable agricultural marketing initiatives are inadequate and cannot be spread in Turkey. In this context, first of all, the supports provided by the government to improve agricultural marketing systems, such as EU funds for rural development should be compatible with the goals of sustainable marketing. For this purpose, it should be examined whether all proposed projects related to agricultural marketing meet the social, economic, and environmental principles of sustainable marketing. It is important that supporting organizations, especially civil society organisations, should take an active role for faster dissemination and adoption of sustainable agricultural marketing practices in Turkey. These organizations may provide technical assistance in preparing successful project proposals and training to farm groups. In addition, the other organizations, such as local administrations, producers' associations, cooperatives, can contribute to the success of sustainable agricultural marketing initiatives. The use of direct marketing strategies and vertical integration attempts in sustainable agricultural marketing initiatives that will likely be implemented in Turkey is important in terms of the success of the initiatives. It's also essential to bring to the fore the various themes, such as regional delicacies, safe production methods, human and environmental health, regionalism, regional artisanship, and biodiversity to cultivate a successful marketing strategy in promotional activities of sustainable agricultural marketing initiatives.
