Recently, food safety which has become one of the decisive factor in demand for all food products, is becoming a major concern due to increasing sensitivity of consumers to food production and consumption. As honey is produced and marketed on more uncontrolled conditions, which is relatively different from other agricultural products, the food safety issue is becoming more intense. In this study, it is examined what kind of applications are applied in food safety in bee products in Turkey. In the second part of the study, it is aimed to determine the importance of food safety in honey consumption of urban consumers in Niğde province based on the primary data and to put consumer's consciousness in this subject. For this purpose, it was conducted a survey by interviewing face to face with 286 consumers. In the study, besides basic statistical methods, univariate analysis of variance and factor analysis method were also used to determine the effective factors in purchasing according to income groups. As a result of the research, it was determined that there is a great lack of confidence in the quality of honey in purchasing from the market due to both the concern of sugar added fraudulent honey and residual problem by consumers. For this reason, consumers prefer to buy honey from directly producers rather than market. In addition, consumers are more likely to believe that honey is less safety than in previous years. Health consciousness is an important factor in consumers purchasing honey and health and quality consciousness develops positively especially as the income level of consumers’ increases.

The experiment was conducted to assess the integrated effects of pre-emergence herbicides and hand-weeding on weed control, yield components, yield, and their economic feasibility for cost effective weed control in faba bean. The experiment consisted of 12 treatments viz. pre-emergence s-metolachlor (1.0, 1.5 and 2.0 kg ha-1) and pendimethalin (1.0, 1.25 and 1.5 kg ha-1), each at three rates metolachlor, s-metolachlor + one-hand-weeding, pendimethalin + one-hand-weeding, two-hand-weeding, complete weed free and weedy checks arranged. The weed flora consisted of broadleaved and sedge with the relative densities of 81.02 and 18.98 % at Haramaya district, and 80.83% and 19.17%, at Gurawa district, respectively. Application of s-metolachlor and pendimethalin 1.0 kg ha-1 each supplemented with hand weeding 5 WAE significantly (p ≤0.01) affected the broadleaved weeds, sedges and weed dry weight at both sites. S-metolachlor 1.0 kg ha-1 supplemented with hand weeding 5 WAE gave the lowest total number of weeds (8.29 m-2) following the weed free check. Higher grain yield (3555.8 kg ha-1) was produced with s-metolachlor 1.0 kg ha-1 supplemented with one-hand-weeding 5 WAE following complete weed-free at Gurawa. The benefit gained from s-metolachlor and pendimethalin at 1.0 kg ha-1 each supplemented with one hand weeding 5 WAE were greater than the value recorded from the weedy check by 216% and 198 %, respectively. S-metolachlor 1.0 kg ha-1 supplemented with hand weeding 5 WAE treatment resulted in the highest grain yield and economic benefit. However, in case labour is constraint and s-metolachlor herbicide is timely available, pre emergence application of s-metolachlor at 2.0 kg ha-1 should be the alternative to preclude the yield loss and to ensure maximum benefit.

Multistoried agroforestry systems as a form of jackfruit-eggplant based is increasingly recognized as a promising option to counteract the catastrophic effects of climate change through providing multifaceted benefits. Unfortunately, farmers of Bangladesh did not manage their jackfruit orchard in a scientific manner. Therefore, the present study was aimed to assess the productivity and profitability of jackfruit-eggplant based agroforestry system after modification from a traditional jackfruit orchard during the period of July 2012 to December 2013. Five treatments covering four orientations of jackfruit tree and an open field was used as a control treatment. To observe the growth and economic performance of the system; soil moisture and temperature, DBH, number of fruits per tree, fruit length, fruit width, fruit weight, total yield, BCR, and LER were calculated following different established methods. The yield of jackfruit dramatically increased by 81% in the agroforestry system in compared to sole cropping, while eggplant shows inverse trend. Soil moisture was high in agroforestry system than that of control plot while soil temperature shows reverse pattern. Indeed, agroforestry system had some negative effects on growth performance of understorey crops. Despite, net return and BCR from jackfruit based agroforestry system were 5.58 lakh and 4.56, which was 66 and 45%, respectively higher than sole cropping systems. The LER of jackfruit-eggplant based agroforestry system was 2.17. Considering the main findings, we can elucidate that jackfruit orchards can be transformed to agroforestry system for maximizing production, generating income and conserving environment.

Renewable energy interest is increasing day by day due to the progressive decline of fossil fuels and negative effects on the environment. As is known, generating energy using solar energy is the most popular of renewable energy source applications. One of the reasons for this is that the sun, which is the source of all the energy in the world, will give energy for a very long time. Another important reason is the rapid developments in semiconductor electronics technology. Direct solar water heating with solar collector, power generation without photovoltaic panels, and even power generation with concentrated parabolic systems. In this research, electricity is generated by solar panels used in a traditional plateau house, photovoltaic solar batteries from solar energy and electricity stored in battery benches and electricity stored in the battery is converted to mains electricity through an inverter if necessary. Saving electric elements at home are selected, and the minimum power required for basic needs is provided. In addition, the economics of the designed system was investigated and efficiency analysis was carried out considering the energy efficiency at the optimum level.
