Rabia Göçmen | Gülşah Kanbur
This study was conducted to investigate the effects of hemp seed oil replaced soybean oil as an energy supply on growth performance parameters, carcass yield, liver weight, breast meat pH, and meat color values in quails. A total of 100 one-day old quail chicks were reared in two treatment groups for 5 weeks. The experimental diets were formulated as to contain 4.4% crude soybean(control) and hemp seed oils. According to the results of the present study, crude hemp seed oil replaced soybean oil in the diet was effective on finishing body weight, feed intake, feed conversion ratio, weight gain and carcass yield. All of these parameters were lower than the soybean oil (control) group. Liver weight, and breast meat color values (L*, a*, and b*) have shown similarities between experimental groups. The breast meat pH value decreased significantly in the hemp seed oil treatment group compared to soybean oil group. Using hemp seed oil instead of soybean oil used in quail diets negatively affects performance parameters (except for feed conversion ratio).

Huriye Dönmez Özyakar | Hasan Yılmaz
Bu çalışmanın amacı Burdur ilinde süt sığırcılığı ile birlikte bitkisel üretim yapan işletmelerin, gübre olarak ahır gübresi kullanımlarının farklı işletme büyüklükleri düzeyinde ekonomik analizini yapmaktır. Araştırmanın verileri süt sığırcılığı ile birlikte bitkisel üretim yapan 102 işletmeden anket yöntemi ile elde edilmiştir. Analiz sonuçlarına göre; işletme büyüklüğü arttıkça işletmelerin bitkisel üretimlerinde ihtiyaçları olan bitki besin maddesini, hayvan gübresinden karşılama oranlarının arttığı belirlenmiştir. Ahır gübresinden besin maddesi ihtiyacının karşılanma oranı Grup I, II ve işletmeler ortalaması için sırasıyla; %29,9, %58,9 ve %45,2 olarak hesaplanmıştır. Çiftçilerin gübre olarak ahır gübresi kullandıklarında, Grup I, II ve işletmeler ortalaması için sırasıyla 51,8, 107,1 ve 80,6 TL/dekar tasarruf sağladıkları hesaplanmıştır. Bu sonuçlar ahır gübresi kullanımının çiftçiler için ekonomik olabileceğini göstermektedir. Bununla birlikte, işletmelerde fazla kimyasal gübre kullanımı ile ilişkili olarak besin maddesi kayıplarının olduğu saptanmıştır. İhtiyaç fazlası kimyasal gübre kullanımından dolayı ortaya çıkan besin maddesi kayıpları (fazlalıkları) Grup I, II ve işletmeler ortalaması için sırasıyla 7,1, 15,9 ve 11,8 kg olarak belirlenmiştir. Fazla bitki besin maddesi kullanımından dolayı ortaya çıkan ekonomik kayıp Grup I, II ve işletmeler ortalaması için sırasıyla 65,1, 152,6 ve 110,6 TL olarak hesaplanmıştır. Araştırma bölgesinde ahır gübresi ve kimyasal gübre kullanımında ve yönetiminde çiftçilerin bilgi düzeylerinin yetersiz olduğunu söylemek mümkündür. Ahır gübresi kullanımından önce çözülmesi gereken önemli bir sorun, çiftçileri toprak analizinin önemi hakkında bilgilendirmektir.

There are few studies in Botswana which have examined the relationship between agriculture and economic growth. The uniqueness of this study is grounded in investigating disintegrated agriculture components into crop production and livestock production and investigating their nexus with economic growth. This study estimated the short and long term effects between crop production, livestock production and economic growth in Botswana for the period 1990 to 2017. The Auto-Regressive Distributed Lagged (ARDL) bounds testing approach was employed to investigate the stated relationship. Study findings from the ARDL bound testing approach confirm evidence of a long-run equilibrium relationship between crop production, livestock production and economic growth. Results indicated that livestock production has a positive and significant impact on economic growth both in the short run and long run. On the other hand crop production has a positive and significant impact on economic growth only in the long run. Efforts towards supporting agricultural sector growth should be emphasized to promote agricultural sector productivity in a bid to forge a move away from dependence on imports of food in Botswana. To enhance economic growth, in both the short run and long run, the government of Botswana and all relevant stakeholders should invest in and promote livestock production. In the long term, policies that foster crop production are essential for economic growth.

Kuru baza göre başlangıç nemi %83,95 ± 0,01 y.b. (5,24 ± 0,003 kg su kg KM-1) olan 100 ± 0,10 g ağırlığındaki Deveci armudu dilimleri (Pyrus communis L. cv. Deveci) son nemi %11,40 ± 0,06 y.b. (0,13 ± 0,001 kg su kg KM-1) değerine ulaşıncaya dek gölgede kurutma, 60, 80 ve 100°C’de sıcak havayla kurutma yöntemleriyle kurutulmuş ve bu yöntemlerin kurutma süreçleri sırasıyla 11150, 437, 252 ve 148 dakikada tamamlanmıştır. Çalışmada deneysel olarak elde edilen zamana bağlı ayrılabilir nem oranı değerleri yirmi farklı ince tabaka kurutma eşitliği kullanılarak modellenmiştir. Buna göre 60°C ve 100°C için deneysel verilere en yakın sonuçları veren modelin Modified Henderson & Pabis eşitliği olduğu; buna karşın gölgede kurutma ve 80°C’de kurutma yöntemlerinde ise sırasıyla Alibas eşitliğinin ve Jena & Das eşitliğinin en iyi modeller olduğu görülmüştür. Gölgede kurutma yönteminde her hangi bir enerji tüketimi olmamasına karşın bu yöntemin oldukça uzun olması ve ürünün kalite parametreleri üzerinde olumsuz etkilere yol açması gibi nedenler Deveci armudunun kurutulmasında gölgede kurutma yönteminin kullanışlı bir yöntem olmadığını ortaya koymuştur. Bununla birlikte toplam enerji tüketiminin kurutma sıcaklığının artmasıyla yükseldiği görülmüştür. Ayrıca sıcaklık artışının kalite parametrelerini de olumsuz etkilediği tespit edilmiştir. Kurutma süresi ve özgül enerji tüketimi gibi işletim parametrelerinin yanı sıra parlaklık, kırmızılık, sarılık, kroma, hue açısı, toplam renk değişimi ve kahverengileşme indeksi gibi kalite parametrelerinin taze ürüne oldukça yakın olmasından dolayı 60°C’de sıcak havayla kurutma yönteminin Deveci armudunun kurutulması için uygun bir yöntem olduğu görülmüştür.

Potato is a high potential food security crop in Ethiopia. Genetic variability is the basis of all crop improvement programs. The study was conducted at Adet in 2018 with the objective of assessing the extent and pattern of genetic variability of potato genotypes for yield and yield related traits. A total of 36 potato genotypes were evaluated for 18 quantitative traits in simple lattice design. The analysis of variance revealed that highly significant difference among the tested potato genotypes for all quantitative traits except stem number per hill. The phenotypic coefficient of variation was ranged from 4.56 to 56.01% (for specific gravity and unmarketable tuber yield ha-1 respectively) and the genotypic coefficient of variation was ranged from 2.32 to 40.66% (specific gravity and late blight severity percentage respectively). Days to attain 50% emergence, leaf area index, number of marketable and total tubers per plant, marketable and total tuber yield ha-1, and late blight severity percentage showed high heritability and high genetic advance as percent of mean. Most of the traits had high phenotypic coefficient of variation and genotypic coefficient of variation; and coupled high heritability with high genetic advance as percent of mean. Traits having high heritability and high genetic advance as percent of means is effective for simple selection.

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.

This study was aimed at investigating the effects of dietary supplementation with different levels of olive cake meal (0%, 2.5%, 5% and 7.5%) on the fattening performance and slaughter and carcass traits of quails. For this purpose, 400 one-day-old Japanese quail chicks were randomly assigned to 4 groups, each with 5 replicates. The quails were fed on either a basal diet alone (Control Group) or a basal diet supplemented with olive cake meal at rates of 2.5% (Group I), 5% (Group II) and 7.5% (Group III) for a period of 42 days. At the end of the fattening period, dietary olive cake meal was observed not to have caused any adverse effect on body weight, feed intake and feed conversion rate. Eviscerated hot carcass weight, eviscerated cold carcass weight, wing weight, breast weight, thigh weight and edible visceral organ weights were determined to have improved in the treatment groups that received dietary olive cake meal, when compared to the control group. In conclusion, dietary supplementation with olive cake meal, a waste product of the olive oil industry, at a level of 5%, was observed to produce the closest and most similar results to those of feeding on the basal diet. Thus, it is suggested that olive cake meal could be used as an alternative feedstuff for poultry. Furthermore, the use of olive cake meal as an alternative feedstuff would contribute to reducing both feed costs and environmental pollution.
