The processes involved in the conversion of cassava tuber into various products generate large volumes of wastes in solid, liquid and gaseous forms. These wastes when discharged into the environment have serious environmental impacts on the natural composition and structure of soil. The aim of this research work was to investigate the effects of cassava whey on the physicochemical properties and metal contents of soil samples around Gari facrory at Erinfun Village along Federal Polytechnic road, Ado-Ekiti. The physicochemical parameters determined were the pH, moisture content, loss on ignition, organic matter, water holding capacity, bulk density, particle density, total porosity, calcium (Ca), magnesium (Mg) and cyanide (CN). Heavy metals determined were lead (Pb), zinc (Zn), copper (Cu), manganese (Mn), cadmium (Cd), chromium (Cr) and iron (Fe). The presence of cassava whey in the soil led to increasing soil acidity, moisture content, water holding capacity, CN, Cr, Ni, Pb and As concentrations while reductions were observed in total porosity, organic matter, loss on ignition, particle density, Ca, Mg, Fe, Mn and Zn concentrations. The results show appreciable variations of physicochemical parameters and heavy metal contents when compared to the control sample.

In this study, it was aimed to identify the change in some micromorphological characters in Prunus laurocerasus L. leaves obtained from 6 different provinces located in the areas where different climate types are dominant, depending on their habitat. In this regard, the leaf samples were collected from Prunus laurocerasus L. individuals in the provinces of Rize, Samsun located in the areas including the European-Siberian, Irano-Turanian and Mediterranean phytogeographical regions. The leaf epidermis images were obtained with the help of SEM on the collected leaf samples, and the required measurement procedures were performed on these images with the help of “Image J” measurement program. By measurements performed on the leaf epidermis surface, Stoma Length (µm), Stoma Width (µm), Pore length (µm), Pore width (µm) and Stoma Density (in an area of 1 mm2) measured such as micromorphological characters. The data obtained were subjected to the Variance analysis and Duncan’s test, and the change in these characters depending on their habitat was statistically evaluated. At the end of the study, it was determined that there were statistically significant differences at the confidence level of minimum 95% among the conditions of the habitat in terms of all characters except for the stomatal width.

Kesme çiçek sektöründe, çiçeğin kalite parametrelerinin ve vazo ömrünün uzun süre korunması hem ürünün ekonomik değerini hem de satıla bilirliğini artırmak açısından önem taşımaktadır. Benzer şekilde, hasattan sonra soğanlı süs bitkilerinin toprak altı organlarının soğuklama gereksiniminin giderilmesi amacıyla depolanması aşamasında, ürünün hasat sıcaklığından depolama sıcaklığına hızlı bir şekilde getirilmesi önem arz etmektedir. Ürünün kalitesini artırırken kayıpları en aza indirmek için geçmişten günümüze pek çok yöntem geliştirilmiştir. Bu yöntemlerden biri de ön soğutma yöntemidir. Ön soğutma, ürünün hasat sıcaklığından depolama sıcaklığına hızlı ve etkin bir şekilde düşürülmesi olarak tanımlanmaktadır. Ön soğutma, hem ürünün hasat sonrası soğuk depoya konulması hem de depolama yapılmaksızın doğrudan satışa çıkarılması durumlarında, ürünün dayanım süresini ve kalite parametrelerini artırmak için kullanılabilmektedir. Uygulandığı tarımsal ürünlerin yapısal ve fizyolojik özelliklerine bağlı olarak ön soğutma, havayla, suyla ve vakumla olmak üzere temelde üç ayrı yöntemle yapılabilmektedir. Bu çalışmada, ön soğutma yöntemleri süs bitkilerine uygunlukları bakımından detaylı bir şekilde tartışılmıştır.

Competition is fierce in the world markets of agricultural products. It is especially harder for developing countries to compete with the wealthier industrialized countries. Canada entered in the lentil production mainly for export purposes in the early 1990s and exports nearly all of its lentil products every year. As Canada has become the dominant power in lentil trade, Turkey’s lentil production has declined notably. In the study, Turkey’s adaptation to this trend is investigated. Based on the results, it is concluded that Turkey’s market share has not changed in its traditional markets and its export has risen both in quantity and value. For instance, Turkey’s lentil export has increased from 127 Thousand tons in 1997 to 178 Thousand in 2013. This is achieved through partnerships between Canadian and Turkish entrepreneurs. Furthermore, lentil producers in Turkey have shifted to alternative crops, which yields higher income.

This study was conducted to evaluate the effects of In ovo injection of β-Alanine which is a modified form of the alanine amino acid on hatchability, hatching weight, chick quality score and survival in broiler breeder eggs. For this purpose, 120 fertile eggs from Ross 308 breeder (32-week-old) were allocated randomly to four groups with 3 replicates. Except the negative control group eggs (non injected; NC), to the amniotic fluid of the eggs in the other 3 groups were injected with 1 ml solutions 0.9% salt (Positive control, PK), 0.75% (0.75βA) or 1.5% (1.5βA) by using 19 mm and 27 gauge needle. Death rates at the different stages of embryonic development, hatching yield, weights and quality scores of chicks and mortalities were recorded at hatching day. Hatching weight of the chicks in the 0.75βA group was higher than other two control groups. Accessing feed, determined as an indicator of chick quality, was better in the 0.75βA group. Conversely, mobility score of chicks in the NC group was higher than other groups. Hatching yield, chick quality score and mortalities of the first week were not affected from In ovo βA injection. Results of this study demonstrated that In ovo βA injection can be used up to 1.5% without any deteriorations on weight, quality and mortalities of chicks but 0.75% βA injection induced better hatching characteristics.

Karyotype properties of of six endemic Onobrychis taxa (O. beata, O. cilicica, O. fallax, O. podperae, O. sulphurea and O. lasistanica) naturally grown in Turkey were determined using squash preparation method and similarity of these endemics with cultivated taxon (O. viciifolia) were revealed. Ploidy levels of Onobrychis taxa were diploid (2n=14) except O. lasistanica and O. viciifolia (2n=28). Basic chromosome number is x=7 and chromosomes ranged from median to sub median with regard to centromere position. While the longest total chromosome length was measured in O. cilicica (28.21 µm), the shortest total chromosome length was in O. beata (21.47 µm). O. cilicica and O. sulphurea have satellite on chromosome 1 and chromosome 2, respectively. Hierarchical cluster analysis was performed to determine the relationships among the Onobrychis taxa and they were separated into three groups. O. fallax, and O. podperae were in the first group while O. sulphurea and O. cilicica were in the second group. O. beata, O. lasistanica, and O. viciifolia were assigned to the third group.

Bu çalışma mürdümük “M” (Lathyrus sativus L.) tahıl ikili karışımlarının silaj verimi ve kalitesini belirlenmek amacıyla yürütülmüştür. Tahıl olarak yulaf “Y” (Avena sativa L.) ve arpa “A” (Hordeum vulgare L.) kullanılmıştır. Karışımlar %80:20, 60:40 ve 40:60 tohum oranlarıyla ekilmiş, kontrol olarak mürdümük ve tahılların yalın ekimleri de kullanılmıştır. Hasat yalın tahıllar ve karışımlarda tahıllar süt olum, yalın mürdümükte ise tam çiçeklenme döneminde yapılmıştır. Silaj örneklerinde; fiziksel gözlemler (renk, koku, strüktür) ile kuru madde, ham protein, ham kül, laktik asit, asetik asit, bütirik asit, potasyum (K), fosfor (P), kalsiyum (Ca), magnezyum (Mg), demir (Fe), çinko (Zn), mangan (Mn), kobalt (Co), bakır (Cu), selenyum (Se) ve sodyum (Na) içerikleri belirlenmiştir. Karışımların silaj verimi 703,6 (%100M) – 1939,0 (%80M+%20A) kg/da arasında değişmiştir. En yüksek laktik asit içeriği %4,078 ile yalın arpada belirlenmiş ancak, %40M+%60Y (%3,198) ve %40M+%60A (%2,937) karışımları da yalın arpa ile aynı grupta yer almıştır. Karışımların asetik asit ve bütirik asit değerleri ise %0,001–0,187 ve %0,312–1,101 arasında değişim göstermiştir. Mineral içerik bakımından %100M ve %60M+%40Y silajları diğer karışımlardan daha yüksek değere sahip olmuştur. Sonuç olarak, yalın ekime oranla mürdümüğün tahıllarla ekilmesi verimi önemli ölçüde arttırmıştır. Arpa hem yalın olarak hem de karışımlarda yulaftan daha iyi performans göstermiştir. Bu itibarla mürdümüğün arpa ile 60:40 tohum oranında karışık ekilmesi silaj verimi ile kalitesi açısından daha uygun görülmüştür.

The effects of ground flaxseed (0-0.5%) and pH (3.88-8.12) on the emulsion properties of beef were studied using a model system. A central composite rotatable design was used to determine the response surface. pH, flaxseed and their interactions had significant effects on the emulsion properties of beef. pH and the interaction between pH and flaxseed increased emulsion capacity (EC). Flaxseed and pH increased emulsion stability (ES) until a critical point, which was reached at a flaxseed level of 0.42% and a pH of 7.02. pH decreased emulsion density (ED) and increased emulsion activity (EA). Moreover, the interaction between pH and flaxseed on EA was found to be significant. pH and flaxseed increased emulsion viscosity (EV), and the increasing rate was higher in basic medium than acidic.

E. coli is one of the most important food borne pathogen, which could be transmitted by milk and milk products. To assess the role of dairy milk as the source of drug resistant E. coli, we examined 50 raw dairy milk samples (25-farm milk + 25-market milk) from some selected areas of Bangladesh by cultural, morphological, biochemical and antimicrobial sensitivity tests. In the preliminary observation, the mean total aerobic mesophilic count of market and farm raw milk samples were 8.98 and 8.68 log CFU/ml, while mean coliform count were 4.20 and 3.03 log CFU/ml respectively. Thirty-three E. coli isolates were recovered from collected samples (66% 33 of 50) and this pathogen was more prevalent in market milk (76%, 19 of 25) than farm milk (56%, 14 of 25). In addition, most of the isolated E. coli exhibited resistance against ampicillin and cefotaxime. This result shows that, the raw dairy milk and its products could be a source of human drug resistant E. coli.
