Savaş Atasever | Violetta Tóth | Edit Mikóné Jónás
The aim of this study was to determine the factors affecting mastitis cases and to estimate the correlations of somatic cell count (SCC) with milk yield in Holstein cows. The study was conducted in two private dairy farms in Hódmezõvásárhely, South-Hungary. A total of 882 Holstein cows were tested by SCC, fat and protein contents of milk monthly intervals. To test milk SCC and components, two groups were designed, and to examine effect of parity on first mastitis day (FMD) and total mastitis cases (TMC), four groups were divided. It was noted that higher SCC caused to higher TMC. While cows had higher protein content exposed to higher FMD and TMC, cows had lower daily milk yield (DMY) had higher values by mastitis case parameters. In parity evaluation, only primiparous cows had statistically lower TMC. The cows with lower SCC were found in advance in change of milk yield (CMY) up to 6.858±0.947 kg. A negative correlation coefficient was estimated between SCC and DMY. Finally, monitoring SCC of milk is offered to prevent milk production losses and new mastitis occurrences in the herds.

Biology of the lonicera whitefly, Aleyrodes lonicerae Walker (Aleyrodidae: Hemiptera) were studied on violet, Viola tricolor L. (Violaceae) plants. Whitefly adults were collected from Mercurialis annua L. (Euphorbiaceae) plants in Adana. The development duration of egg, first, second, third, fourth larval (pupa) stages of A. lonicerae on V. tricolor were 9.17, 6.33, 5.83, 4.00, 5.17 and 30.50 days for the females and 10.27, 5.91, 5.55, 4.82, 4.55 and 31.10 days for the males, respectively. The total development duration from egg to adult of female and males of A. lonicerae were 30.50 and 31.10 days. The mortality rate (%) of egg, 1., 2., 3. and 4. larva (pupae) stages on violet leaves were 22.45, 18.37, 12.25, 4.08 and 8.16, respectively. According to life table depending on pre-adult stages on violet plants, the biggest k value determined was for the first larvae stage (k=0.1174). At the same time, the k-values determined indicated the stage with the highest mortality rates. In the studies conducted for host plant preference, the average numbers of eggs deposited by the females of A. lonicerae were significantly different between rose (2.67/two leaves) and violet (15.83/two leaves) in the same experimental area. The study was conducted in a climate-controlled room in at 20±2°C, 40%±5 relative humidity.

This study was carried out to investigate the floristic features (family, preference by grazers, growth form and response to grazing) and qualities of forage species collected from mountainous rangeland (Akdağ Mountain, Ladik) in the middle Black Sea region of Turkey. Forage samples were collected five times by 15-day intervals from the before-flowering stage to the after-flowering stage in 2015 and 2016. The total number of species was 105 species belonging to 73 genera and related to 26 families. Of the total species, 20 were from Poaceae (19.0%), 30 were from Poaceae (28.6%). Rests of the species belonged to other families (52.4%) dominated by families such as Asteraceae (13/55) and Lamiaceae (6/55), of which 26 species were weeds harmful to animals. While the percentages of decreaser, increaser and invader species were 16.2, 12.4 and 71.4, those of annual, biennial and perennial species were 31.9, 2.9 and 65.2, respectively. The number of species preferred by grazing was 74 (70.5%), while the number of non-preferable species was 31 (29.5%). The ME (MJ kg-1), RFQ and quality category of legumes, grass, and other botanical families were found as 8.88±0.07, 130.9±3.05 and very good, 8.00±0.07, 83.2±1.62 and good, and 8.98±0.07, 141.0±3.62 and premium, respectively. These results can be used as a management tool to improve rangeland quality and sustainability. The evidence from this study is that floristic pattern is not merely a result of invader forage species, but also might be a beneficial result that deserves further study for mountainous rangelands.

In this study, an investigation of the preference and perception of the different broiler housing and feeding systems among staff and students of Eskisehir Osmangazi University, Turkey was undertaken. A structured questionnaire was administered with a face-to-face to 790 randomly selected respondents [257 academic staff (academicians), 166 non-academic staff (worker with a secondary school national graduate diploma) and 367 undergraduate students (students)]. Most respondents preferred chicken (63.3%) and beef (32.0%) meats to fish meat (4.7%). The number of academicians preferred broiler meat (16.8%) was lower than those of students (52.6%) and workers (30.6%). There were significant differences among respondents in terms of preference and perception of different production sources of chicken meat. The proportion of academicians who preferred conventional broiler meat (68.2%) was higher than students (25.4%) and workers (6.4%). The impact of mediatic information (disinformation) about broiler meat relating to ingredients and/or feed additives used in broiler nutrition was higher on academics and students compared to workers. The results of the study indicated that as the level of education increases, the negative perception increased due to false media reports about chicken meat production and subsequently, the preference for chicken meat decreased.

In this study, the effects of two traditional, three reduced and a zero tillage methods applied for nine years on GEA and PMN were determined and compared. The study, initiated in 2006 as randomized block design, includes a total of 18 plots with 3 replications for 6 different soil tillage systems. In the study, six different soil tillage methods are applied, namely conventional tillage with stubbles (CT-1), conventional tillage with stubbles burned (CT-2), reduced tillage with heavy disc harrow (RT-1), reduced tillage with rototiller (RT-2), reduced tillage with heavy disc harrow (RT-3) and no tillage (NT). Winter wheat was grown as the main crop every year or corn and soybean was grown following the harvest of wheat (second crop) every other year. Differentiation of tillage systems led to a significant variation in GEA and PMN concentrations. The GEA concentration, which increased significantly with the decrease in tillage density, varied between 44.68 mg PNP kg-1 h-1 (CT-2) and 207.66 mg PNP kg-1 h-1 (STI). However, the trend determined in GEA could not be detected in PMN. Although PMN concentration was significantly higher in soils under NT, it was included in the same statistical group with RT-1 for PMN concentrations. Higher PMN concentration in no till soils can be possibly related to the non-disturbance of soil structure. The results of study revealed that reduced and no tillage systems are extremely necessary to increase the quality of soils in the region.

Ayşegül Gedük | Kubilay Kurtulus Bastas | Şaban - Kordali | Ferah Yılmaz
Xanthomonas aXonopodis pv. phaseoli (Xap)’nin neden olduğu adi yaprak yanıklığı hastalığı, tropikal ve subtropikal iklimlerde önemli verim kayıplarına neden olan ve tohumla taşınan en önemli fasulye bakteriyel etmenlerinden biridir. Hastalıkla mücadelede antibiyotikler ve bakırlı preparatlar kullanılmakta, ancak patojenin dirençli mutantlarına ve fitotoksisiteye neden olmaları nedeniyle sorunlar yaşanmaktadır. Bor (B), bitki için temel bir besin elementidir ve ayrıca bitki hastalıklarına direnç sisteminde önemli bir rol oynar. Bu çalışmada, 12 farklı bor bileşiğinin Xap üzerindeki etkileri araştırılmıştır. In vitro denemelerde, kimyasalların Xap popülasyon gelişimlerine etkileri ve MIC değerleri belirlenmiştir. Kontrollü koşullarda, 6 haftalık hassas fasulye çeşidi Aras 98 bitkileri, 108 CFU ml-1 yoğunlukta Xap süspansiyonu ile inokule edilmişlerdir. Bitkiler, in vitro’da belirlenen ve kimyasala göre değişen 5 farklı (1, 5, 10, 20, 40 mM) konsantrasyonda 7 gün ara ile iki kez muamele edilmişlerdir. Hastalık şiddeti, 1-9 skalası ile değerlendirilmiş ve kontrole göre (%81,15) en düşük hastalık şiddetine sahip bileşikler; sodyum tetrafloraborat (%13,88) ve potasyum tetrafloraborat (%15,38) olarak belirlenmiştir. En düşük hastalık şiddeti ise borik asit uygulaması (%78) ile elde edilmiştir. Bitkilerde kimyasalların fitotoksik etkileri tespit edilmemiştir. Çalışmadan elde edilen bulgulara bağlı olarak, bazı bor bileşiklerinin, fasulyede adi yaprak yanıklığı hastalığı üzerindeki önemli etkileri ile organik ve sürdürülebilir tarım içerisinde yer alabileceği düşünülmektedir.
