Öğe Altitude: Is determinant for tuberculosis incidence?(2006) Tanrikulu A.Ç.; Abakay A.; Abakay Ö.; Alp A.In the last year, there have been very important improvements about tuberculosis (TB) all over the world. In this study, it was researched TB control studies at two cities in Turkey between 1999 and 2003 in order to determined the factors affecting to TB prevalence. The forms using those dispensaries in two cities to informing about diagnosis and treatment of TB have been investigated retrospectively. In This period, 2387 new TB patients were determined in Diyarbakir, 1844 (77.2 %) of them were pulmonary TB and 543 (22.8 %) extrapulmonary TB. 691 (37.5 %) with pulmonary TB were smear positive. In same period, 375 new TB patients were determined in Kars, 276 (73.6 %) of them were pulmonary TB and 99 (26.4 %) extrapulmonary TB. 50 (18.1 %) patients with pulmonary TB were smear positive. The average incidence of TB was 37.55/100000 in Diyarbakir and 19.59/100000 in Kars (p<0.05). The average incidence of pulmonary TB was 29.04/100000 in Diyarbakir and 14.53/100000 in Kars (p<0.05). The altitude at Diyarbakir is 660 meters and 1768 meters in Kars. According to research from the State Planning Organization of Turkey, there has been an important difference regarding the rates of urbanization and rates of literacy between two city (p<0.05). It was thought that the significant difference regarding incidence of TB between two cities was due to the difference of altitude of those city (2.3 times). Moreover, it was thought that some socioeconomic parameters could be affective on TB prevalence. However, some extensive study should be carrying out to clearly understand the factors affecting TB prevalence.Öğe Conservation and conventional tillage methods on selected soil physical properties and corn (Zea Mays L.) yield and quality under croppin system in Turkey(2010) Sessiz A.; Alp A.; Gursoy S.This study was conducted to determine the effects of conventional and conservation tillage on the some soil physical properties, penetration resistance (PR), seedling emergence rate, yield and yield components under southestern of Turkey conditions. The experiments were carried out at 2003 and 2004 years in a clay loam soil. Six different soil tillage methods in corn production were tested. The experiment was performed in randomized block design with six treatments and each treatment consists of three replications. No significant (p>0.05) treatment differences in seedling emergence were found between the tillage treatments for both years. Plant height was found significant between years while treatment effects were not significant. However, the highest plant height was obtained in 2004 under CT tillage method. The stalk thickness was found significant between years while treatment effects were not significant. The cob length was not found significant between years and treatments.The lowest cob length was obtained under NT method. It was found that yield was significantly (p<0.01) different between years. The yield in the second year was found to be higher than that of the first year. The highest yield was found in CT method as 678.00 kg/da and the lowest yield was found in RT4 method as 535.66 kg/ha in year 2003. The highest yield was found in CT method as 778.66 kg/da and the lowest yield was found in RT4 method as 642.33 kg/ha in year 2004. The highest fuel comsumption was obsorved as 33.48 Lha-1 in conventional method (CT) whereas the lowest value was found in direct seeding method as 6.6 Lha-1.Öğe Determination of competition capacity of local Karacadag and Osmancik-97 rice variety against some weeds(Bangladesh Botanical Society, 2017) Alp A.; Celik S.; Kaya B.In the first part the effects of aqueous extracts of leaf, straw, hull and seed of 7 different weed species on germination of local Karacadag and Osmancik-97 rice seeds was investigated. In the second part, Karacadag and Osmancik-97 rice seeds were sown together with weed seeds to plots, and it was determined effects of varied weed species on germination, root, seedling, leaves and grain yield of rice varieties in field conditions. As a result of the findings; aqueous extracts of Echinochloa crus-galli L. Beauv, E. oryzoides(Ard.) Fritsch., Amaranthus retroflexus L. and Physalis peruviana L. were found to be the weeds which inhibit the germination of both rice seeds the most in both laboratory and field conditions.Öğe The evaluation of durum wheat landraces for resistance to wheat yellow rust (Puccinia striiformis f. sp. tritici) in the Southeastern Anatolia Region, Turkey(WFL Publisher Ltd., 2009) Alp A.; Sağir A.Fifty wheat samples collected from 11 different durum wheat landraces produced in the central district and villages of Diyarbakir province were used as study materials. Suspension, prepared as 352,000 spores per ml by using the spores composed of a mixture of yellow rust (Puccinia striiformis f. sp. tritici) species provided by the Field Crops Central Research Institute, was injected into plant tissue in the pre-earing stage during the 2004-2005 and 2005-2006 growing seasons. Of the 50 durum wheat landrace samples 15 used in the study were classified as resistant to yellow rust, 19 as semi-resistant and 14 as semi-susceptible. Moreover, it was also found that one sample from the Aşure landrace was in the susceptible group with the highest rust intensity of 61.68% while one sample from the Ruto landrace was found to be in the immune group with an intensity of 0%.Öğe Tillage effects on sunflower (helianthus annuus, l.) emergence, yield, quality, and fuel consumption in double cropping system(2008) Sessiz A.; Sogut T.; Alp A.; Esgici R.The relation between crop growing and soil tillage treatment are play important role in agricultural production. Soils under conventional tillage (CT) generally have lower bulk density and associated higher total porosity within the plough layer than under no tillage (NT). No-till farming can reduce soil erosion, conserve soil moisture and minimize labor and fuel consumption. The aim of this study were to investigate the effects of conventional, reduced and notillage methods on soil physical properties, sunflower yield and yield components, protein and oil content and fuel consumption in Southeastern of Turkey. Six tillage methods for the second crop sunflower were tested and compared each other within after lentil harvesting at 2003 and 2004 years in a clay loam soil. According to results, the first year, the bulk density had decreased from 1.29 to 1.09 g cm-3, the second year the ?b had decreased from 1.41 to 1.23 g cm-3. Differences between years and tillage methods in terms of yield were found signifi cant (p<0.05). However, no differences were found between the NT and CT. There were also no signifi cance differences in content of protein, oil and ash among six tillage methods. The highest fuel consumption was measured in conventional method (CT) whereas the lowest value was found in direct seeding method as 33.48 L ha-1 and 6.6 L ha-1, respectively.
