Turkish hazelnut (Corylus avellana L.) is naturally grown as a multi-stemmed shrub. This hazelnut produces lots of suckers. Suckers compete with the main branches for nutrients and water. Because the emergence of suckers negatively affects crop management in the hazelnut orchards are required to eliminate at least twice a year. Flaming is an alternative method to chemical and mechanical control methods. In this study, the effect of gas pressure, flaming time on fuel consumption and flaming efficiency in hazelnut sucker control were evaluated. The trials were carried out in an shrub ocak (in Turkish) type hazelnut orchard The results show that the torch flaming method is a useable method for hazelnut basal sucker cleaning. Gas pressure and flaming time had significant effects on fuel consumption and flaming efficiency. 150 s flaming duration and 3 bar pressure is sufficient for the flaming application. Durations above this time will increase fuel consumption and time loss.

Ever-developing agricultural technologies and progress in communication science increase competition and globalization in converge countries. Agricultural fairs offer ambient to bring producers and input-suppliers of agriculture together at certain places and times. They offer direct and efficient information about new technologies to producers. German Agricultural Society and Leader Farmer Association have jointly organized outdoor fairs in Turkey since 2010. Agriculture Days Fair is one of the most important events among these jointly organized fairs. This study was conducted to determine the reasons for producers’ participation in these fairs held in 2015 and 2017 and to determine the effects of socio-economic characteristics of the producers on their reasons for participation in these fairs. A total of 589 questionnaires were made in this study (250 in May 2015 fair and 339 in August 2017 fair). The same questionnaire forms were used in both years. CHAID analysis technique was employed in analyzing data gathered from the producers. It was observed that producers generally participated in agricultural fairs just for the excursion or spent time with their families at weekends. However, it was also determined that the producers were informed about the agricultural fairs by producer organizations and Leader Farmer Association participated in the fairs to promote a new products or to give information about new technologies and inputs. It can be suggested that beyond informing producers about the fairs, Leader Farmer Association formed within the scope of Leader Farmer Project initiated with the support of German Agricultural Society (DLG) should convey information about how important the fairs are in the acquaintance with introducing new information and technologies.

Rainbow trout (Oncorhynchus mykiss) were examined effects of apricot kernel oil (Prunus armeniaca L.) on the immune mechanisms. After Fish weight 40 ±0,03 g was intraperitoneal (i.p.) injection 1% and 10% apricot kernel oil (AKO), blood was taken from the caudal vein of anesthetized (50 ppm, benzocaine) fish. Myeloperoxidase production (MPO), Serum bactericidal activity, protein levels, Lysozyme response (LYS) and total immunoglobulin (Ig) were determined on days 3, 7, 14 and 21. The same strategy was conducted on a control bunch. No contrasts were found within the levels of immunuglobulin between the control and test groups. However, there were considerable increases in bactericidal activity, MPO, LYS, protein levels and important differences were detected between the control and experimental groups. AKO can be utilized to improve the resistant instruments of rainbow trout.

In July 2017, three specimens of an alien fish species were caught by the amateur fishermen in Kızılırmak River at Sivas city center. One of the fish specimens was taken from the fishermen for ichthyologic examination. The morphological, metric (23 features) and meristic characters (13 features) of this specimen were determined. The alien fish is with ovoid shape and flattened laterally. Mouth is in a sub-ventral position. The tooth row is double. Teeth formula are 3,2 / 2,3 (at first row on maxil) and 2 / 2 (at second row on maxil), 3,3 / 3,4 (at first row on mandibul), 1,1 (at second row on mandibul). The number of rakers on the first gill arch is 33. The scale numbers in line lateral are 107 (on right side) and 103 (on left side). The number of branched rays of dorsal, anal, pectoral, and ventral fins are 14, 24, 14, and 7; respectively. As a result of the evaluation of morphological, metric and meristic characters, it was decided that the alien fish caught from Kızılırmak was Piaractus mesopotamicus (Holmberg, 1887) belonging to the Characidae family. This species is also called as the small-scaled pacu. P. mesopotamicus is not among to native fish fauna of Kızılırmak. It is a fish species which originated from South America and is a tropical freshwater fish. These alien fish specimens which were caught by the amateur fishermen, probably translocated from a hobbyist aquarium to this aquatic system. Both directly and indirectly, invasive fishes affect a wide range of native organisms from zooplankton to mammals across multiple levels of biological organizations ranging from the genome to the ecosystem. This study is the first scientific record for Sivas aquatic systems related to alien fish species.

Çalışma, endofit bakteri uygulamalarının farklı kuraklık stresi altında yetiştirilen biber fidelerinin gelişimi üzerine etkisini ortaya koyabilmek amacıyla, kontrollü koşullarda saksı denemesi şeklinde yürütülmüştür. Biber çeşidi olarak Mostar F1; endofit bakteri olarak da Ochrobactrum sp. (CB36/1) ve Bacillus sp. (CA41/1)) izolatları uygulanmıştır. Bakteri uygulaması, 109 cfu/ml yoğunluğunda iki kez (ilk uygulama 10 ml- ikinci uygulama 15 ml) yapılmıştır. Tohum ekiminden itibaren, 52 gün boyunca tüm saksılar düzenli olarak sulanmıştır. Kontrol (B0) uygulamalarında sulamalara 2 gün aralıklar ile devam edilmiş; ikinci uygulamada (B1) dört günlük bir kuraklık stresi ve son uygulamada (B2) ise 8 günlük bir kuraklık stresi uygulanmıştır. Bitki gelişim parametreleri olarak; gövde çapı, sürgün boyu ve kök uzunluğu, sürgün yaş ve sürgün kuru ağırlığı, yaprak sayısı, kök yaş ve kök kuru ağırlığı incelenmiştir. B1 ve B2 stres uygulamalarının, bitki gelişimine etkisinin genel olarak olumsuz olduğu tespit edilmiştir. Endofit bakterileri uygulamalarının ise farklı kuraklık streslerinin yol açtığı olumsuzluğa karşı nispeten olumlu düzeyde etkilere sahip olduğu belirlenmiştir.

Catalase from the thermophilic fungus Mycothermus thermophilus is a bifunctional enzyme with a secondary phenol oxidase activity (CATPO). MtCATPO catalyses the oxidation of catechol, chlorogenic acid, caffeic acid and (+)-catechin to yield mainly dimers, and higher molecular weight oligomers and polymers. The role of this phenol oxidase activity is not known. Here, the antioxidant capacities (AC) of the phenolic substrates in the absence and presence of MtCATPO were compared. The oxidized products displayed enhanced AC reaching a maximum of 2.4-fold with catechol. Other phenol oxidases (laccase and tyrosinase) did not yield AC enhancement to the same extent. MtCATPO-treatment increased AC of green and black tea infusions, as well as water extracts of samples collected from a black tea production line up to 28%. The bifunctional MtCATPO appears to be an important antioxidant enzyme with a wide range of potential applications in the food, neutraceuticals and pharmaceuticals industry.

This experiment was carried out under the study entitled “Ripening regulation of the banana Cv. Malbhog using different ripening inducers” for controlling the ripening of the banana, for improvement of quality attributes and post-harvest life of banana. The experiment was conducted at laboratory of horticulture, Agriculture and Forestry University, Rampur, Chitwan, Nepal from 14th March to 16th April 2019. These experiments were laid out in completely randomized design in which the first experiment comprised of seven treatments consisting of distilled water spray, ethephon @ 250 ppm, ethephon @ 500 ppm, ethephon @750 ppm, ethephon@1000 ppm, Dhurseli (Colebrookea oppositifolia) leaves and Ripe banana replicated thrice. Different post-harvest parameters were recorded at the interval of two days for the experiment till any one of the treatment attained score 6 in the color chart. In this experiment, the CI-6 stage was reached earlier on the 9th day with the use of ethephon @ 1000 ppm but ethephon @ 500 ppm was found more effective regarding quality parameters with TSS (21˚B), and TSS/TA (34.66). The maximum physiological loss in weight (12.927%) and pulp peel ratio (3.65) was observed with ethephon@1000ppm and the minimum was achieved in banana sprayed with distilled water. The shelf life of banana was seen minimum (13.33 days) in ethephon @ 1000 ppm and maximum (20.33 days) in banana sprayed with distilled water.

Bu çalışma büyüyen bıldırcın rasyonlarına farklı seviyelerde arı poleni ilavesinin performans, karkas ve serum biyokimyasal parametreleri üzerine etkilerini belirlemek amacıyla yürütülmüştür. Araştırmada günlük yaşta toplam 240 adet karışık cinsiyette bıldırcın civcivi her birinde 40 civcivin bulunduğu dört tekerrürlü altı muamele grubuna rastgele dağıtılmıştır. Muamele rasyonları bazal rasyona 0, 3, 6, 9, 12 ve 15 g/kg arı poleni ilave edilerek hazırlanmış olup, bıldırcınlar 42 gün süren deneme boyunca bu rasyonlarla yemlenmiştir. Deneme sonunda canlı ağırlık, canlı ağırlık artışı, yem tüketimi ve ölüm oranı gibi performans parametreleri muamelelerden etkilenmezken, rasyona 9 g/kg seviyesinde arı poleni ilavesi ile yemden yararlanma oranı önemli ölçüde iyileşmiştir. Karkas parametrelerinden ise relatif karkas, göğüs ve but+sırt ağırlıkları rasyona farklı seviyelerde arı poleni ilavesinden önemli ölçüde etkilenmiştir. Serum biyokimyasal parametrelerinden yalnızca albümin konsantrasyonu muamelelerden etkilenmiş; rasyona 3 ve 9 g/kg seviyesinde arı poleni ilave edilen gruplarda kontrol grubuna göre önemli ölçüde azalmıştır. Deneme sonuçlarına göre rasyona 9 g/kg arı poleni ilavesinin yemden yararlanma oranına olumlu etkilerinin olduğu söylenebilir.

Soil is one of the most important factors affecting the plant development on the basis. The method mostly applied for the purpose of accelerating the plant development and ensuring the increase in products is to increase the nutrients in the soil, namely fertilization. Fertilization ensures lots of food elements in the soil to get mixed in the soil and change the soil composition. Another factor affecting the plant growth speed and productivity is shadowing. Shadow conditions change the light receiving amounts of the plant and directly affect the plant photosynthesis speed. In addition; shadowing not only affects the dissolution and in-soil mixture speed of the fertilizers applied to the soil, but it also directly affects the humidity content of the soil. In this study, it has been aimed to determine the food element changes in the soil on the lavender individuals grown under different shadow conditions and fertilized with different fertilizers. The lavender used in the study has been selected due to the fact that it adapts to dry areas, it is abstinent in terms of soil and it is an important and income-generating medical aromatic plant. As a result of the study, it has been determined that shadowing statistically affects salt, carbon, phosphor, nitrogen and potassium and fertilization statistically affects phosphor, nitrogen, potassium, carbon and salt at least at 95% confidence level.
