This study was conducted in the Aegean region conditions of Turkey in 2020. It was carried out on May-505, a local cotton variety. The study examined the variation of seed yield, water use efficiency (WUE), and irrigation water use efficiency (IWUE) of cotton with different irrigation programs and water levels. The field trial, which was designed as two factors and three replications, was designed according to the randomized complete block trial design. Four different irrigation levels (IL) (100%, 67%, 33%, and 0%) and two different irrigation scheduling approaches (gravimetric and pan evaporation) were investigated in the study. Seasonal water use values in treatments varied between 215 (0%) and 746 (100% - Pan evaporation approach) mm during the production period. The average yield values obtained with irrigation levels, which have essential effects on cotton seed yield, are listed as follows; 2057 kg ha-1 (IL-0%), 3471 kg ha-1 (IL-33%), 3771 kg ha-1 (IL-67%), and 5083 kg ha-1 (IL-100%). It was determined pan evaporation applications performed higher yields than gravimetric applications. WUE values were between 0.63 – 1.04 kg m-3. The gravimetric method’s yield response factor (ky) was 0.73, and the pan evaporation method’s yield response factor (ky) was 0.89. These results show that cotton is tolerant of water stress. In conclusion, although the pan evaporation approach with 100% treatment is suggested for cotton production in the parts of the Aegean region within the semi-arid climate zone, while water resources are sufficient. When the results are evaluated in terms of seed cotton yield for a deficit irrigation strategy, IL-67% treatment with a gravimetric approach can be used.

The study aims to investigate the monthly changes in the prices of culture fish that were sold in retail fish outlets in Sinop in 2019 and determine the correlations between the prices of the species. The retail outlets were determined using stratified sampling and divided into three groups as I (high), II (medium), and III (low) with respect to their product range and sale amounts. Each sale group was represented by two independent retail outlets. The prices were determined twice a month at the same time of the day during the study. The retail outlets were determined to sell sea bream (Sparus aurata), sea bass (Dicentrarchus labrax), and rainbow trout (Oncorhyncus mykiss) culturing of which are carried out in Turkey. The difference in the monthly prices of the species was not statistically significant. There was a positive and moderate relationship between the prices of sea bream and sea bass (r=0.69), a positive and strong relationship between the prices of sea bass and trout (r=0.85), and a positive and strong relationship between the prices of sea bream and trout (r=0.71).

Marine litter, which can be seen in almost all seas in recent years, is a serious problem for the environment. Similarly, the same problem also exists in Turkey's seas. This study was carried out in 4 different areas, each of which is 100m², in the Yumurtalık Fishing Port in İskenderun Bay. Marine litter was removed from the seabed by diving in these selected areas in April 2016 and June 2017. In the study, a total of 157.2 kg of rubber (49.5%), 118.9 kg of glass (37.4%), 21.61 kg of plastic (6.8%) and 19.94 kg of metal (6.3%) marine litter were detected and removed. It was determined that the marine litter extracted in 2017 was less by weight compared to 2016 (p

Study on toxigenic mycoflora and potential mitigation effect of Christmas Melon (Laganaria Breviflorus) extract in unpolished rice sold in Abeokuta Ogun state of Nigeria was carried out. Unpolished rice gotten from markets in Abeokuta were aseptically transported to the laboratory, serial dilution to reduce the fungal load was carried out and were plated on Potato Dextrose Agar (PDA) and Methyl Red Dessicated Coconut Agar (MRDCA) respectively. Microscopy, macroscopy, toxigenicity test and inhibition studies with the peeled and unpeeled fruit of Laganaria breviflorus fermented for seven days was carried out. Results reveal the predominance of Aspergillus as the major genera, specifically, A. niger, A.flavus, A. parasiticus, A. fumigatus, A. terreus, A. nidulans. Other fungi genera isolated include Penicillium, F`usarium, Mucor, Alternaria and Rhizopus . Of the 11 fungi genera isolated, 9 were toxigenic of which the zones of inhibition of unpeeled whole fruit extract of Laganaria breviflorus range from (3 - 28mm) where A. nidulans shows the highest susceptibility to the whole fruit extract of Laganaria breviflorus while the zone of inhibition of peeled fruit extract of Laganaria breviflorus ranges from (3 - 22mm) where A. parasiticus, Fusarium specie and P.chrysogenum showed the highest susceptibility . As the day progresses the zone of inhibition becomes wider. Unpeeled LB extract exhibited more zones of inhibition than the peeled LB extract. Laganaria breviflorus fruit extracts in the study demonstrates a potential in reducing toxigenic fungi, consequently a means to reducing mycotoxins in staple foods in Nigeria.

In this study, the White Layer Pure Line that housing as individual cage system at the Poultry Research Institute in Ankara was used. Eggs obtained from 24, 28, 32, 36 and 40 weeks old eggs were collected 3 times a day in the morning (10:00), noon (12:00) and evening (15:00). Egg Size and Egg Width (YBE), Shape Index and Elongation (SIE), Egg Surface Area and Volume (YAH), Shell Weight and Shell Thickness (CAS), Number of Pores and Pore Density (GSY), Yellow Ratio and Yellow Weight (SOA), Albumen Weight and Albumen Ratio (AO) were examined in 438 eggs obtained from these chickens found in these cages which are three tiers as upper, middle and bottom. The difference in cage layer did not have a significant effect on the calculated properties. On the other hand, the effect of on all traits obtained from these calculations based on egg weight was found to be significant.

The compost product, which offers many benefits such as the evaluation of organic wastes, improvement of soil structure, neutralization of toxins and pH balance of the soil, has significant potential for the improvement of our country's lands. Considering the development of animal existence in our country, the production of compost product to be obtained from feces, which is the product of these animal beings, is an issue that needs to be emphasized. The choice of plant location, which must be determined for an investment to be made for the acquisition of this product emerges as a separate problem. For this reason, in this study, the order of optimality among the alternatives for compost plant installation is considered as a multi-criteria decision making problem. For this purpose, the criteria determined for 10 clusters with the potential of 35,829 animals that can produce compost in Samsun were weighted by the SWARA method. The optimal ranking of these 10 compost clusters was carried out using the COCOSO and WASPAS methods, by means of the criteria weights taken into consideration. According to the ranking results obtained from both methods, it was determined that the cluster number 27 was in the first rank, the cluster no 13 was in the second rank, and the cluster no 14 was in the third rank.

The compost product, which is a biologically active substance, emerges as a result of microbial decomposition of organic materials under controlled conditions. This product, which is used for the improvement of soil structure and the development of agricultural products, also offers opportunities in terms of minimizing the damage caused by organic wastes to the environment. It is important to encourage efforts for compost production, especially in terms of both disposal and economic evaluation of wastes generated in animal production farms. Determining the most suitable location of a facility for the utilization of animal wastes as compost, which will be obtained from livestock enterprises scattered in different geographical areas, will be an essential study in terms of minimizing operating costs. For such a facility, it would be an appropriate approach to use multi-criteria decision making methods to choose among predetermined facility location alternatives. In this study, a total of 17 facility location alternatives with 83,163 cattle potential in Çorum province were ranked according to the criteria determined and weighted by means of SWARA method. The optimal ranking of 17 alternatives determined by K-Means clustering analysis was carried out by COPRAS and MAIRCA methods. According to the ranking results obtained from both methods, it was determined that cluster number 6 was in the first rank, cluster number 4 was in the second rank, and cluster number 3 was in the third rank.
