2020
Sedef Akıncı | Dilek Bostan Budak
In the study, which is conducted in mountain villages of Mersin province, 99 people selected by simple random sampling method. The data were collected by face to face interviewed. 64.6% of the individuals were male, 35.4% female and 35.4% had a primary school diploma. The average household width was 2.38 and the average age was 50.32. Small ruminant and beekeeping activities are the main source of livelihood for individuals who lives in mountain villages, but also they are benefiting from forest products. As forest products, medicinal aromatic plants such as centaury, thyme, rosehip, mushrooms, blackberries, carob, and straw are used. Men work more intensively in jobs such as wood, timber and resin, which require heavy labour, while products such as centaurs, blackberries and rosehips are collected by women. Individuals' perceptions of forest and forest products do not change according to gender, age and education level. This is because they need the forest and its’ products to maintain their lives. In general, it is determined that the population living in the mountain villages live a life based on forest and forest products. In this context, protection of forest areas in the region is very important both for the prevention of environmental damage and for the people of the region. In addition to individual awareness, support should be provided by the relevant ministries on the use and protection of forests and products. The aim of this study was to identify the use of forest products and opinion about forest who lives in mountain villages of Mersin.

Mustafa Usta | Abdullah Güller
The tomato plant exhibiting leaf rolling, witches’ broom, distorted and elongated flower’s sepals in Iğdır province, Turkey, was observed. Total DNA extraction was performed from the symtomatic fresh tomato sample. All DNAs were subjected to Direct and Nested polymerase chain reaction (PCR) with universal primer sets that amplified the 16S rRNA of phytoplasmas. PCR products were purified from agarose gel and cloned into the pGEM T-Easy cloning vector. Recombinant plasmids were introduced into the prokaryotic cloning bacteria by electroporation. Plasmid isolation was performed by selecting one of the positive clones randomly and sequencing was performed by Next Generation Sequencing (NGS). Sequencing results revealed that the 16S rRNA gene associated with phytoplasma was 1251 nucleotides in size, and this sequence was denominated as ‘Iğdır 10’ isolates and recorded in the GenBank under the MT344968 accession number. The virtual restriction fragment length polymorphism (V-RFLP) and phylogenetic analysis of the 16S rDNA sequence confirmed that the cause of disease in infected tomato plants was 'Candidatus Phytoplasma trifolii' ('Ca. P. trifolii') (16SrVI-A, Clover proliferation group), with a 1.00 similarity coefficient. This present study is the first report of ‘Ca. P. trifolii’ and its nucleotide sequence analysis in naturally infected tomato in Iğdır province.

This experiment was conducted in tomato field at Agriculture and Forestry University (AFU, Chitwan, Nepal) between October 2016 and May 2017 to evaluate effect of net house on invasive insect species of tomato moth, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae). The trial was setup with two treatments inside net house and under open conditions and was designed with four replications. The adults of T. absoluta were observed significantly lower numbers inside the net house (1.41 adult/trap) compared to the open condition (24.84 adult/trap). The T. absoluta population increased with rainfall. The marketable yield was significantly higher inside the net house (100.91 ton/hec) due to reduction of damage to tomato fruit (4 ton/hec) by T. absoluta. The initial level of investment was found to be higher inside the net house when compared to open cultivation. In terms of economic analysis in long term aspect only, the net house is a suitable means of pest management against T. absoluta.

Processing of melon plays a significant role in the livelihood of rural women as it serves as their major occupation. Despite its significant role, the women processors were faced with some challenges. This study, therefore, identified the challenges faced by women in melon processing in Enugu-Ezike Agricultural Zone of Enugu State, Nigeria. Primary data were collected from 80 respondents using a structured questionnaire coupled with an interview schedule and analysed using descriptive statistics. The results showed that the majority of the women processors were advanced in age, well experienced, do not belong to a cooperative society, and relied strictly on processing melon as their source of livelihood. They had an average income of N286,400 (USD 751.71) per annum. Low capital, poor credit facilities, high transportation cost, price fluctuation, rapid deterioration, low supply of melon, poor storage facilities, high cost of processing machine, and breakage of seed were the identified constraints facing them. The study recommended that the women processors should form a cooperative society which will help in financing and easy marketing of their products. Also, the government should provide financial assistance, good storage facilities, and subsidized melon processing machine to increase efficiency.

This research was conducted between 2011 and 2015 at research field of Faculty of Agriculture, Eskişehir Osmangazi University for evaluating two tillage methods (conventional and reduced), three crop rotations (wheat-wheat; wheat-fallow; wheat-chickpea) and four N levels (0, 50, 100, 150 kg ha-1). The experimental design was split-split plot with three replicates. Tillage methods were in main plots, crop rotations in subplots and N levels in sub-sub plots. The N concentration of grain and straw harvested from aboveground plant organs was separately determined using by the Kjeldahl digestion method after the plant samples were ground. Then, grain protein content, nitrogen use efficiency (NUE), nitrogen uptake efficiency (NUPE), nitrogen utilization efficiency (NUTE) were calculated. According to results, effects of tillage methods on NUE were unclear. Conventional tillage methods resulted in higher NUPE than reduced tillage in the last three years of the experiment. The NUTE was higher in reduced tillage than conventional in 2011-2012 and 2014-2015. The effects of tillage methods on grain yield were different due to the climatic conditions. Wheat-chickpea rotation had the better results for examined traits in this research. Increasing nitrogen doses increased grain and plant protein rate, however it decreased NUE and NUPE. The effects of nitrogen doses on NUTE were ambiguous. Nitrogen use efficiency and NUPE is traits that can be differed according to changeable grain yield depend on environmental conditions. Therefore, the experiments should be conducted for more than four years for revealed absolute effects both soil tillage method and nitrogen fertilization.

Nowadays, whitening of stained teeth has become the most popular topic in aesthetic and cosmetic dentistry. Because of the side effects of materials that were used for bleaching, in this study the effects of some plants which were used in Anatolian folk medicine on the treatment of tooth staining were examined. In this study, upper central incisors which were extracted for periodontal reasons were used. The colour values of numbered teeth were obtained and the teeth were immersed into three different essential oils of medicinal plants (Mentha piperita, Ocimum basilicum, Rosmarinus officinalis, Salvia officinalis) for different time periods (1 day, 1 week, 1 month). At the end of the immersion periods, colour measurements of all samples were made and the colour changes were analysed. Obtained data were statistically analysed by using ANOVA and Duncan test. As a result of the variance analysis, plant species and the duration of immersion was found to be statistically significant. Within the limits of this study, we can indicate that tested medicinal plants has a whitening effect by resulting significant change in tooth colour.

In this study, effects of medium components and inoculum size on the protease production by Bacillus sp. EBTA6 that was isolated from a home-made Tarhana sample were investigated. The cell-free supernatant of bacterium cultured on a shaking incubator for 24 h was used to test protease activity as the response. With a total number of 11 factors, 12 different experiments were run and the highest experimental protease activity was measured as 2280.4 U/mL. Results were analyzed statistically by ANOVA and the most efficient factors were detected as yeast extract, dipotassium phosphate, casein, and peptone with a contribution of 93.78, 2.19, 1.96, 1.31%, respectively. For validation of the selected factors, a further experiment was performed by using of yeast extract (9.98 g/L), dipotassium phosphate (1.27 g/L), casein (8.69 g/L), and peptone (9.88 g/L) obtained from the design equation. The experimental response was found as 2411.4 U/mL which was only 5.5% higher than the predicted response showing that the model was applicable.
