Bu çalışmada 8. hafta canlı ağırlık tartımlarına göre sınıflandırılarak büyütülen kazların 16. hafta kesim yaşında performans özellikleri ile göğüs ve but etinde renk ve pH değerlerinin belirlenmesi amaçlanmıştır. Çalışmaya günlük 478 adet palaz ile (dişi-erkek karışık) başlanmıştır. 8. Haftada canlı ağırlığa göre sınıflandırma (hafif, orta ağır, ağır) yapıldıktan sonra 270 adet kaz (dişi-erkek karışık) ile çalışmaya devam edilmiştir. 10. ve 16. haftalarda, ağır grupta canlı ağırlığın daha yüksek olduğu ve hafif grupta ise canlı ağırlık artışının daha yüksek olduğu belirlenmiştir. Yemden yararlanma oranı da hafif ve orta ağır grupta daha düşük bulunmuştur. Ayak ve but ağırlığı ile göğüs pH değeri ağır grupta, abdominal yağ ağırlığı ve oranı orta ağır grupta, baş oranı hafif grupta daha yüksek tespit edilmiştir. Sonuç olarak, sınıflandırmalı büyütmenin hafif grupta canlı ağırlık artışı üzerine etkisi olumludur. Kaz yetiştiriciliğinde hedef kesim canlı ağırlıklarına üniform olarak ulaşmak için bu yöntemden faydalanılabilir.

The objective of this work was to determine the effects of UV-C and chitosan coatings, alone or in conjunction, on the quality of strawberry fruit during storage. The treated fruits were examined for weight loss, respiration rate, soluble solids content, titratable acidity, ascorbic acid contents, total anthocyanins, total phenolic contents, decay incidence and sensory analysis of strawberry fruit were investigated during cold storage 1±0.5°C and 90±5% RH for 15 days. The result showed that chitosan coating with UV-C irradiation could further reduce decay incidence of strawberry fruit, restrain increase of respiration rate and weight loss of strawberry fruit compared to other treatments. Moreover, the total anthocyanins and total phenolic contents were maintained at higher level, and the decrease of ascorbic acid was restricted during storage period. Likewise, sensory analysis results also showed the effectiveness of UV-C + chitosan treatment by retaining the quality of strawberry fruit. Control and individual UV-C treatment had similar effects on respiration rate and weight loss. The results showed that UV-C + chitosan treatment can be an effective method for enhancing the phytochemical content and delaying fruit senescence of strawberry fruit during cold storage.

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.

Su hasadı teknikleri kurak alanlarda yağmur sularını biriktirerek su sıkıntısının ve kuraklığın etkilerini azaltmanın yanı sıra, toprak ve su koruma açısından da yarar sağlamaktadır. Bu çalışmada, yağışların yetersiz olduğu yarı kurak iklime sahip Güneydoğu Anadolu bölgesinde, sulama olanağı bulunmayan genellikle eğimli arazilere tesis edilmiş zeytin bahçelerinde toprak ve su erozyonu kontrolünü sağlamak amacıyla, Negarim mikro havza yağmur suyu hasadı tekniği uygulanmıştır. Bu çalışmada; yağmur suyunun bitkinin kök bölgesinde birikimini sağlamak amacıyla Negarim adı verilen mikro havzalar içerisine yerleştirilen plastik örtü, taş örtü, mikro-havza yüzeyinin sıkıştırılması ve kontrol konularından oluşan 36 adet mikro-havzanın toprak ve su erozyonuna olan etkisi değerlendirilmiştir. Araştırmada 2009-2010 yılları boyunca yüzey akış ve sediment kayıpları ile bitki gelişimi ölçülmüştür. Araştırma sonuçlarına göre yıllık ortalama yağışı 250 ile 400 mm arasında değişen deneme alanında, 2 su yılı boyunca meydana gelen ortalama maksimum yüzey akış 6201 L/parsel ile plastik örtü konusunda, ortalama minimum yüzey akış 810 L/parsel ile taş örtü konusunda belirlenmiştir. Ortalama maksimum sediment kaybı 1163 g/parsel ile yüzey sıkıştırma konusunda, ortalama minimum sediment kaybı ise 673,5 g/parsel ile taş örtü konusunda ölçülmüştür. Mikro-havza yüzeyi plastik örtü ile kaplı olduğundan erozyon kontrolünü en iyi şekilde sağlayan uygulama plastik örtü olarak saptanmıştır. Plastik örtü konusu en iyi yüzey akışı gerçekleştirdiğinden bitki boyu gelişimi yönünden ortalama 107,5cm uzunluk ile en iyi uygulama olmuştur. Sonuç olarak kuru koşullarda ve eğimli arazilerde üretimi yapılan zeytin bahçelerinde Negarim mikro havza su hasadı tekniğinin ağaçların büyüme ve gelişimi arttırmanın yanı sıra toprak ve su muhafazası açısından da yararlı ve uygulanabilir bir teknik olduğu sonucuna ulaşılmıştır.

This study presents a new sex pheromone trap for European Grapevine Moth, Lobesia botrana, to monitor its field population without direct field observations in Turkey. The study was conducted in Hadim and Taşkent (Konya) districts in 2016. Viticulture has been carried out for many years in both districts where the maximum vineyards are located. Due to the distance to the center and the difficulty of transportation to these districts, there has not been conducted any detailed studies until today. Therefore, this study about L. botrana, which is harmful in these vineyards, was planned. In order to monitor the pest population, the cameras were placed onto the pheromone traps, and it was tried to get information about the population development of the pest via internet without going to the vineyards. For this purpose, four locations in Hadim and one location in Taşkent district were selected and one pheromone trap was established in each location before the bud burst in vineyards. The camera was placed on each pheromone trap and was linked with vMEyeIPC program via internet. The time of first adult flight and the population development of adult L. botrana were determined. The first adult flight began at the beginning (7/4/2016) and in the middle of April (15/4/2016) in Hadim and Taşkent, respectively. The number of offspring and the maximum number of pest individuals caught in traps were recorded in vineyards in both districts.

This study was carried out to determine the effect of non-genetic factors on growth and reproductive traits in Saanen goats. For this aim, total of 274 Saanen goats and kids were investigated for growth and reproductive traits in South Marmara Region of Turkey. Fertility parameters were evaluated during two reproductive years. Saanen kids were measured from birth to 6 months of life. The average live weights at birth, weaning, 60th, 90th, 120th and 180th days of age were calculated and determined as 3.05±0.04kg, 11.80±0.27kg, 12.26±0.08kg, 14.20±0.32kg, 17.41±0.45kg, 25.01±0.65kg, respectively. The effects of sex and birth type on live weights until 90th days of age; maternal age only on birth weight; month at birth on all of investigated days were found significant statistically. The pregnancy, birth rate per pregnancy (BRP), birth rate per mating (BRM), infertility, abortion, kidding rate (single, twin or triplet), survival rate (until weaning), number of kids per parturition (NKP), number of kids per mating (NKM) were found; 92.98%, 85.07%, 91.25%, 7.02%, 8.75%, 36.12%, 49.00%, 14.88%, 89.13% and 1.74±0.06, 1.42±0.07 respectively. The effects of maternal age on all rates (out of BRM and abortion rate); the year on birth, abortion, single kidding rate, survival rate and NKM were found significant for reproductive traits. The advanced reproductive performance and rapid growth rates were observed in Saanen goats. Environmental factors such as age, year, sex, birth type and month at birth were found significant on some growth and reproductive traits in Saanen. So consideration of these factors could be useful as a selection criteria in dairy goat breeding.

In this study, fish consumption preferences of the families living in the district of Almus in Tokat province and the factors that are effective in choosing them were investigated. In the scope of the study, the data obtained from face-to-face interviews with households were used. In the study, consumers prefer which of the alternatives of rainbow trout (Oncahorynchus myciss), carp fish (Cyprinus carpio) and spring fish (Silurus glanis) consumed most of the fish species found in Almus Dam Lake, and the importance level of consumer preference in this choice. the Analytic Hierarchy Process (AHP) method was determined by the AHS method. Criteria consist of price, nutritional value, taste, freshness, bone condition, sold place, habit, hunting, aquaculture. It has been determined that the most attention is paid to the freshness (0.175) in the direction of the findings and that the criteria of taste (0.136), sold place (0.133) and food value (0.122) follow. In the preference of fish consumption, Rainbow Trout criterion was given priority with 48% points. İt is aimed to determine the importance level of the criteria that are effective in consumers ‘preference of fish consumption in the direction of obtained findings and to be a guide for fish farmers and sellers.

The aim of this study was to evaluate the chemical composition and mineral bioavailability of T. tetraptera fruit pulp, an aromatic wild edible plant, using standard methods. The pulp were extracted from mature dried fruits obtained from plants at Awabo (5°30’14.2”N and 4°01’30.6”W) and Loviguié villages (5°48’24.5’’N and 4°20’15.8”W), all in south-eastern Côte d’Ivoire. The results of chemical analysis revealed that T. tetraptera fruit pulp contains carbohydrates (63.73±0.51%), crude protein (7.01±0.66%), crude fat (1.18±0.01%), ash (5.38±0.18%), fibre (11.78±0.02%), moisture (40.52±0.18%) and an energy value of 254.74±0.15 kcal/100g. Besides, the results showed a relative high amount of vitamin A (2.11±0.02%) and vitamin B9 (261.78±0.01 µg/100g) while vitamin E, B1 and B2 in trace concentration. Otherwise, the phytochemical analysis (mg/100g) based on dry weight revealed an appreciable amount of total phenol (2407.10±8.36), flavonoids (14.29±0.56), tannins (55.11±0.44), catechin (392.93±1.01) and also carotenoids (108.19±7.42 µg/100g). Organic acids profile (mg/100mL) showed citric acid (175.06±0.02) and salicylic acid (109.85±0.01) as major organic acids. Mineral composition (mg/100g) on dry weight basis revealed that potassium (1303.67±0.58) is the most abundant followed by phosphorus (303.33±5.77), calcium (187.33±0.58) and magnesium (141.33±0.57). Furthermore, the Phytates:Zn, Phytates:Ca, Oxalates:Ca and Phytates*Ca:Zn molar ratios recorded were all below than recommended threshold values, implying a bioavailability of zinc and calcium. These data indicate that the pulp of this fruit could be a good source of ingredient for both medicine and food industries in production.

Against rapidly developing industry and increasing population, natural resources on earth are getting destroyed. One of the most important adverse effects on the environment is perhaps the depletion of ozone layer which protects the earth from harmful effects of UV radiation, especially UV-B. The effect of UV-B radiation can vary according to species. At high rates of UV-B radiation, many disorders in DNA, photosynthesis, morphological and physiological structure, and biomass accumulation in plants are observed. In this review, the effects of high UV-B radiation on terrestrial ecosystem are discussed.
