Cem Baltacıoğlu | Nisanur Ülker
In this study, pumpkin (Cucurbita pepo L.), which is usually produced for its seeds, was used for production of whole pumpkin powder directly incorporated into biscuit formation. Fiber, protein and ash content of pumpkin powder are determined 13.4%, 8.5% and 4.7% (dry basis), respectively. Pumpkin powder was added into the dough by means of displacement with the wheat flour at rates of 15%, 30% and 45% during biscuit production. Firmness, work of shear, stickiness and work of adhesion were examined after adding pumpkin flour to biscuit dough at different rates and an increase of firmness, work of shear, stickiness and work of adhesion were recorded as 58.9%, 72.4%, 52.1%, and 29.4%, respectively. A decrease of 24.8% in thickness and 22.7% in volume were observed as the amount of pumpkin flour increases. When the color values were examined, darker biscuits were obtained compared to the control biscuit. Approximately an increase of 232.6% in ash content in biscuits was observed. Biscuits adding pumpkin powder had 58.4% more moisture content than the control biscuit. While decrease of hardness and toughness were observed as 82.3% and 85.4%, respectively, a significantly change of brittleness value was not observed. Biscuits were evaluated in the sensory analysis in terms of crust color, inner color, homogeneity and size of pore, taste, odor, softness, and dissolve in the mouth and greasy feeling in the mouth. According to the results of sensory analysis, biscuits that 45% pumpkin powder was added was the highest rated.

Zinc (Zn) deficiency is an important mineral nutrient problem that restricts the crop yield especially that of the cereals grown in calcareous soils. This study was carried out with the aim of testing the sensitivity of various cereal species consisting of bread (BDME-10, Bezostaja), durum (Kızıltan Ç-1252) and rye (Aslım) to Zn deficiency. In experiments carried out under greenhouse conditions plants were grown at two different Zn doses (Zn 0 and Zn 5 mg kg-1). When the plants were 44 days old, Zn deficiency symptoms were observed and scored for the severity of Zn deficiency according to 1-5 scale and the plants were harvested. With respect to the severity of Zn deficiency symptoms, the most severe symptoms were observed in the C-1252 (1.0) and Bezostaja (2.0) varieties while the least mild symptoms were observed in varieties of Aslım (4.0) and Kızıltan (3.0). A distinctive increase in shoot dry matter yield has been realized with Zn application which was highest in Ç-1252 (78.8%) and BDME-10 (52.5%) varieties. Greatly differential responses have been seen to Zn deficiency among cereal species and varieties within the same species. Symptomatically and with respect to dry matter yield while durum wheat was affected severely from Zn deficiency, bread wheat was affected moderately and rye has been seen to be affected least. According to the severity of Zn deficiency symptoms and plant growth cereals which are the subject of experiment have shown a rank as as Ç1252> BDME-10> Kızıltan> Bezostaya> Aslım.

Günümüzde insan ömrünün en az %80’i kapalı mekanlarda geçmekte ve bu kapalı mekanlardaki iç ortam hava kalitesi insanların sağlıklarını ve performanslarını doğrudan etkilemektedir. Özellikle CO2 miktarı belirli seviyelerin üzerine çıktığında baş ağrısı, baş dönmesi, yorgunluk, konsantrasyon bozuklukları, boğaz ve burun tahrişi, burun akıntısı, öksürük ve göz akıntıları gibi pek çok rahatsızlığa sebep olmaktadır. İç ortamdaki CO2 miktarını etkileyen en önemli faktör canlı metabolik faaliyetleridir. Solunumla artan CO2 miktarı fotosentezle azalmaktadır. Dolayısıyla iç mekanlarda bitkiler CO2 miktarını azaltmak amacıyla kullanılabilir. Ancak bitkilerin iç ortamdaki hava kalitesine etkisi konusunda yeterli bilgi bulunmadığından, bitkiler iç ortamdaki CO2 miktarını azaltmak konusunda etkin ve bilinçli bir şekilde kullanılamamaktadır. Bu çalışmada iç mekan süs bitkisi olarak en sık kullanılan bitkilerden birisi olan difenbahyanın (Dieffenbachia amoena Gentil) iç ortamdaki CO2 miktarına etkisinin sıcaklığa bağlı olarak değişiminin belirlenmesi amaçlanmıştır. Çalışma sonucunda difenbahyanın karanlık ortamda yaptığı solunumun sıcaklığa bağlı olarak önemsiz düzeyde olduğu belirlenmiştir. Ancak ışık bulunan ortamda en yüksek etkiyi 23-24℃ sıcaklıklarda gösterdiği, 30°C sıcaklıktaki fotosentez hızının, 20°C dekinden düşük ancak 15°C dekinden daha yüksek olduğu belirlenmiştir.

There are small number of tables that show digestibility and energy contents of compound feeds produced by feed factory in different regions of Turkey. Thus, in this paper, four different compound feed types (dairy cattle, beef cattle, calf and lamb growing feeds), totalling 78 compound feeds were analysed to determine their feeding value, dry matter (DM), organic matter (OM) digestibility and energy content (digestible energy (DE), metabolisable energy (ME) and net energy for lactation (NEL). As a result of this study, the crude fiber (CF) levels were higher than standard values in calf and lamb compound feeds and beef cattle compound feeds; however, in the dairy cattle and calf and lamb compound feeds, the crude protein (CP) values were lower than standard values. These findings are considered highly important for the region’s animal feeding. According to our results, the compound feeds for dairy cattle and lamb being used for ruminant nutrition in Diyarbakir Province of Turkey were found to have low nutrient qualities; however, in the calf feed both the metabolisable energy level and nutrient quantities were low.
