Food waste and loss is an ecological, economic and social problem. The United Nations Food and Agriculture Organization states that approximately one third of all edible foods produced for human consumption are wasted or lost after harvest. The aim of this study is to determine the factors affecting food waste behavior of consumers. In order to reach this aim, a questionnaire was conducted with 583 people in November and December of 2018 in Çorum province. The obtained data were analyzed and explained through Structural Equation Models. As a result of the exploratory factor analysis, a 5-factor structure explaining 76,612% of the total variance was obtained. These factors were named as norm, intention, result awareness, purchasing behavior and planning. These factors were found to have validity, reliability and internal consistency. In addition, it was investigated whether the factors were compatible with the fit indices by means of Confirmatory Factor Analysis. As a result of confirmatory factor analysis, it was determined that the obtained factors met the fit indices values. As a result of Confirmatory Factor Analysis, it was determined that the obtained factors met the fit index values. The effect of the factors on the relationship between each other and the waste behavior were measured by means of the path analysis. As a result of this study, although consumers have positive statements regarding consequence awareness, intent and norms, they have been determined to be unstable in planning and purchasing. Besides, although there was a direct effect of intent and result awareness on waste behavior, it was determined that planning and norms had indirect effects. Considering that the intention is the most influential factor on waste behavior, it should be focused on the activities that will create result awareness in society.

Soil moisture has a vital role in the cultivation of crops. Its sufficiency and availability to crop- water supplies depends on the management practices of soil and amount of available water to the soil. This study examines the influence of rice husk biochar on the water holding capacity of soil in the savannah ecological zone of Ghana. Increasing rate of rice husk biochar increased water-holding capacity of soils. 4t/ha rice husk biochar showed higher significant differences among the treatments. It is recommended that 4t/ha rice husk biochar should be applied to increase the water-holding capacity of the soil.

Strawberry is one of the most preferred fruits all over the world due to its characteristic properties. Due to the morphological structure of fresh strawberries after harvesting, quality losses are observed during cold storage. Therefore, industrial washing of fresh strawberries is especially important for reducing microbial load and increasing shelf life. Demand for the new methods as an alternative to the chemicals used in industrial washing of fruits and vegetables is increasing due to consumer-related health concerns. Ultrasonic washing is a preferred innovative method in terms of reducing the microbial load and maintaining quality properties compared to chemical washing processes. In this study, fresh strawberries were washed with ultrasound (550 W/35 kHz) and peroxyacetic acid (40 ppm) after harvesting. The pH, total acidity, water soluble dry matter (brix), vitamin C, total phenolic content, antioxidant capacity, total viable, mold and yeast count analyses were performed in every two days during 14 days of cold storage of washed strawberries. Ultrasonic washing was found to be more effective in reducing microbial load and preserving bioactive properties of strawberries compared to other method due to its cavitation effect.
