One of the most important factors that increase soil fertility is the amount of soil organic matter. One of the ways to increase soil organic matter is the addition of organic fertilizers. Yemsoy soybean cultivar was used in the study, and pot study was carried out in 3 replications according to the randomized blocks experimental design. In the study, three different fertilizer doses (EC 0- 0.5- 1), three different grape pomace compost (0- 20-40 %) were applied to the peat perlite mixture, and mycorrhiza and bacteria inoculation to these environments. At the end of a 60-day growing period, the plants were harvested from the top of the pot, and measurements were made. In the study, there was an increase in the above-ground fresh and dry weights, root fresh, and root dry weights of soybean plants grown with increasing fertilizer rates. The addition of compost to the growing medium, the addition of mycorrhiza, and bacteria caused different results in the investigated properties. The increase in compost and plant nutrition doses was effective in increasing plant growth.

Teknolojinin gelişmesine ayak uyduramayan küçük aile işletmelerinin, rekabet piyasasındaki mevcut konumlarını korumak ve etkinlik paylarını artırmak önemli bir konudur. Küçük aile işletmeleri gıda üretimin yaklaşık %80’ini karşılamakta ve bu işletmelerin piyasadan çekilmesi gıda arzında ani düşüşe sebep olabilmektedir. Bu çalışmanın amacı küçük aile işletmelerine pazarlama eğitimi sağlanmasının, çiftçilerin becerilerini, üretimi ve karlılığı nasıl artırabileceğini göstermektir. Bu beklentilerin gerçekleşmesi büyük işletmelerin ya da kamunun sağlayacağı desteklerle mümkün olabilecektir. Bu çalışmada oyun teorisi kullanılarak, iki oyuncu (Proje kurucu ve çiftçi) arasında gerçekleşen olası stratejiler dikkate alınmış ve her aşamada elde edilecek kazançlar bulunmuştur. Sonuç olarak, yatırımı yapan kuruluş ile eğitimi alan çiftçinin iş birliği yapması, kazancı artıracağı sonucuna varılmıştır. Bu sonuç güven duygusu, iş birliği ve örgütlenmenin temelini oluşturmaktadır. Böylece üretim artarken, kalifiye eleman eksiği azalacak ve istihdama katkı sağlanacaktır.

In this study, it was aimed to investigate the effect of evening primrose oil (EPO) on some biochemical parameters on nephrotoxicity induced by gentamicin (GM) in rats. The rats used in the study were randomly divided into 4 groups each consisting of 8 rats. The control group, EPO group, GM group and GM+ EPO group. The blood samples were taken 24 hours after the 8-day trial and kidneys were removed and saved for histopathological and PGE2 analysis. The serum creatinine, BUN, calcitriol, Ca, Na, Cl, K and P analyzes were performed via autoanalyser. PGE2 analysis was performed in kidney tissue via ELISA. Histopathological examination of the kidney tissues was performed. The levels of creatinine, BUN and Cl were significantly decreased and PGE2 and Ca increased in GM + EPO compared to GM group. The changes in the biochemical parameters examined and the histopathological findings obtained, it can be said that the EPO weakens the nephrotoxic damage caused by GM and has the protective effects on the kidney.

From all the pigments found in Spirulina platensis, phycocyanin has been found to have a diverse application in various fields, and has a high market demand, calling for a need to increase production and easy isolation methods. In general, phycocyanin production in cells depends on the light conditions, among other factors during the cultivation period. The focus of this study was to look at the effect of different light intensities on phycocyanin production in Spirulina platensis. Other cellular biochemical parameters, including chlorophyll content and protein, were explored under the different treatments. An experimental design containing 4 different light intensities of 20, 150, 300 and 600 μmol photons m2/s was administered with 3 replicates. The results obtained from the study showed that high phycocyanin content was obtained from a low light intensity treatment. Chlorophyll results were a bit in contrary to the results obtained for phycocyanin, with high chlorophyll content obtained in high light intensity treatments. Protein and biomass accumulation also followed the same trend, where they were observed to be higher in high light intensities, with the maximum biomass achieved at 600 μmol photons m2/s and maximum protein content achieved at 300 μmol photons m2/s. Due to the commercial potential of phycocyanin to humans, its low cost downstream cultivation and processing of Spirulina platensis will be of economic advantage to the relevant stakeholders to fulfil the rampant demands and affordability of the blue phycocyanin pigment to both first and third World countries, hence the need of producing phycocyanin using the modified Zarouk’s media which has cheaper if not affordable ingredients.

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.

Roots play an important role in improving crop yield by affecting the amount of water uptake and nutrient acquisition. The objective of this study was to characterize variability in root and above-ground characteristics among three diverse semi-dwarf spring wheat cultivars, ‘Vida’, ‘Oneal’ and ‘Duclair’ and a wild-type cultivar, ‘Scholar’ at early and late growth stages in a greenhouse. Plants were grown in 45-cm long tree pots in a greenhouse under optimal growth conditions. As soil-less media, a mixture of peat (70%) and perlite (30%) was used. Plants were harvested at tillering (GS25-26) with 5-6 tillers, booting (GS43-45), and maturity (GS92). Root and shoot traits indicated significant variability among wild-type and semi-dwarf spring wheat cultivars at those growth stages. The study results showed that root mass per plant at tillering, booting, and maturity ranged from 0.10 to 0.14 g, 0.47 to 0.9 g, and 0.55 to 0.85 g, respectively, while shoot mass per plant varied from 1.7 to 2.5 g, 6.5 to 10.7 g, and 21.2 to 24.5 g, respectively. From booting to maturity, root mass was relatively constant, however, shoot mass increased considerably. Moreover, the average root mass of semi-dwarf spring wheat cultivars was 37% lower at booting and 30% lower at maturity compared to the wild-type cultivar, even though there was no significant variation among the cultivars at the early growth stage. Based on the results of the variability identified in this research, wild-type cultivar, Scholar can be evaluated for the improvement of genotypes with superior root system in breeding programs.

Turkey is known as a top producer and exporter of apricots, both fresh and dried. More than half of Turkey's apricot production is provided by Malatya province. There are many pests and diseases affecting apricots in addition to climatic factors such as frost and hail. Partial shoot drying and sudden drying in apricot orchards have increased in recent years. In this study, it was aimed to determine the chemical control possibilities of Neoscytalidium dimidiatum (Penz.) Crous &Slippers, which is one of the fungal agents that cause partial branch drying and sudden drying in apricot orchards in Malatya province by in vitro studies. For this purpose, Kale 4-C isolate of N. dimidiatum collected from Malatya in a previous study was used. Mycelial growth of N. dimidiatum Kale 4-C isolate in PDA were observed in 0 (control), 0.01, 0.03, 0.1, 1, 3, 10, 30 ve 100 μg/mL concentrations of Azoxystrobin 250g/L, Trifloxystrobin %50, Tebuconazole %25, Floupyram 200 g/L+Tebuconazole 200 g/L, Cyprodinil+Fludioxonil %37.5+25, %70 Thiophanate-Methyl and 400 g/L Phosphorous acide fungicides applications. As a result of the study, Floupyram 200g/L+Tebuconazole 200g/L ve Cyprodinil+Fludioxonil %37.5+25 fungicides effectively inhibited the mycelial growth of the fungus.
