The objective of the study was to compare selected physical and chemical composition of shea butter processed from nut sourced from inorganic and organic fields. The treatments were O (shea butter processed from nut picked from organic fields) and N (shea butter processed from nuts picked from inorganic fields). These treatments were arranged in a Complete Randomized Design and were replicated four times in the laboratory for studies of free fatty acids (FFA), pH, peroxide value, insoluble impurities, unsaponifiable matter, and moisture content. The study revealed that organic shea butter had lower free fatty acids (FFA), lower moisture content, lower pH, less unsaponifiable matter, less insoluble impurities and lower peroxide value as compared to inorganic shea butter shea butter. The lower FFA value of organic shea butter indicates that it can be used for the cosmetic and pharmaceutical industry and for direct consumption. Hence higher chances that organic shea butter and attract premium prices in both local and international markets. The study also revealed that there was a positive relationship between; unsaponifiable matter and moisture content. Insoluble impurities had a very strong correlation with unsaponifiable matter and moisture content. A very strong positive correlation was observed between peroxide value and unsaponifiable matter, moisture content, and insoluble impurities. For good quality butter, nuts should be sourced from organic fields.

The aim of this study was to find potential PGPR from sub-forest soil located different region soils of Turkey. Previous research indicated that the existing bacteria in arable soil are not capable to represent their individual performance most probably due to the competition. To overcome this phenomenon, soils are collected from sub-forest soil of Adana (Ad), Antalya (An), Hatay (Ha), Isparta (Is), Ordu (Or) and Sivas (Si) provinces. Experiment was carried out on the soil existing in Isparta in a greenhouse condition. Four fast growing bacteria colonies in tryptic soy (CASO) agar medium from each province were isolated and then, each isolate cultivated at liquid CASO broth until they reach 106 cfu ml-1. Experiments were carried out with a total of 24 bacteria including 6 province and 4 bacteria cultures from each region. The effects of those bacteria on biomass development and nutrient uptake of maize (Zea mays) were investigated. Sterile broth was applied treatment defined as control. The results revealed that 23 isolates out of 24 stimulated plants shoot dry weight. The highest value observed in the Or1 and Is4 isolates as 12.8 and 12.7 g plant-1 which around 77% higher than control whereas the lowest was in Or2 as 6.45 g plant-1. Plant nutrient concentrations were also influenced from inoculates where An1, Ad1, Or1, Is1 and Is3 significantly increased macro nutrients uptake where total N, available P, K, Ca and Mg were higher by 19%, 14%, 14%, 59% and 41% over the control, respectively. The Fe concentration was found 48% higher in Ad3 isolate. The Cu, Mn and Zn were the highest in Si3 as 43%, 30% and 31%, respectively. In general 4 out of 24 isolates were selected as promising PGPR for both plant development and nutrient uptake of maize.

Fentahun Asrat | Asrat Ayalew | Asfaw Degu
Valuation of postharvest loss and identification of its causes enables to develop proper measures required to reduce losses. The study was conducted at “Fogera” District, South Gondar, Ethiopia between 2017 and 2018 years to assess the extent of postharvest loss of tomato (Solanum lycopersicum L.) and to identify major causes with respective handling system. In this study, a total of 125 farmers and 40 traders (10 wholesalers and 30 retailers) were involved as main respondents. Data collection was done using semi structured interview schedule, key informant interview, focus group discussion and observation. Besides respondents estimation, a sample analysis was conducted to estimate the extent of postharvest loss as per the FAO minimum quality standards. Descriptive statistics such as average, percentage, frequency and standard deviation were used to analyse data and tables, graphs and charts were used to present result. Result revealed that almost half of tomato produced is damaged and puts out of normal use with highest loss at producer level due to different causes which are complex and interrelated across tomato market chain. Marketing situation, insect pest and disease, lack of awareness, low economic status of producers, late harvesting, mechanical damage during harvesting and transportation, poor quality of produce and price fall were some of the reasons identified as major cause of post-harvest loss of tomato. For solving the postharvest loss problems, actors in supply chain has to develop cooperation and effective communication among all the research, extension, and industry personnel involved.

2019
Khaula Sakhr | Sami El Khatib
The Syrian Sumac (Rhus coriaria) is a widely used spice in the Arab world of attractive economic importance in food, cosmetic and pharmaceutical industries. Meat tenderness is one of the very most important factors for customers’ acceptability. The global objective of this study was to add an additional value to Sumac by evaluating its meat tenderizing effect. Crude sumac fruits were used to create three different extracts (aqueous, ethanolic and purified enzymatic extract). Pectoralis superficialis cuts were treated with the extracts and studied for their shear stress, pH, protein and fat contents and collagen. The hypothesis that Sumac could have a meat tenderizing effect was supported by our results showing a significant decrease in shear stress and protein content with increase in collagen solubility. Moreover, an effect on decreasing meat fat was detected, where the aqueous sumac extract decreased significantly the fat percentage in meat. The active enzymes in Sumac were shown to be variate in nature, lipase and protease, with a significant effect on collagen, thus proving Sumac’s possibility to be potentially used as a meat tenderizer.

In this study, the effects of the extracts obtained from flower, stem, leaf, branch and their mixture of Nerium oleander L. on the seed germination and seedling growth of four Pistacia species (Pistacia terebinthus L., P. vera L., P. khinjuk Stocks., P. atlantica Desf. and P. terebinthus L.) were investigated. Five hundred grams of N. oleander was taken from the plant parts and the extracts were mixed with distilled water (1.5 L). The extracts were applied to Pistacia species for 24 and 48 hours. The results showed that the extract had positive effects on their germination and growths of the species mentioned above. The highest germination rate for all the Pistacia species was obtained from the extracts of flower, while the lowest germination rate was recorded in the mixture of all parts of N. oleander mentioned above. Moreover, the treatment time was found to reduce the germination ratio. It was also found that the extracts from the stem of N. oleander were the most effective on the stem height of the Pistacia species studied. It was followed by the extracts from branches, leaves and flower, respectively. Furthermore, the findings indicated that the extracts from the stem of N. oleander had pronounced effect on the stem diameter of the Pistacia species studied. It was followed by the extracts from flower, leaves, and branches, respectively. In general, the effects of the extracts from several parts of N. oleander on the germination and other growing parameters were found to be almost comparable to those of synthetic promoter, Gibberellic Acid (GA3).
