Rüstem Cangi | Gözde Öncel Deveci
In this study, the effects of re-cutting, wounding and disbudding over the base of dormant rootstock cuttings on the grafting success, final take and grapevine sapling quality in grafted grapevine sapling production were investigated. Five different treatments were experimented in this study as of T-1 (in which the base of the rootstock was cut and two distal buds from the base were disbud (standard application); T-2 (in which the base of the rootstock was not cut but two distal buds were disbud); T-3 (in which only the base of the rootstock was cut); T-4 (in which the base of the rootstock was cut and three buds were disbud) and T-5 (in which the base of the rootstock was crashed with a hammer and two distal buds were disbud). Scions of Royal cultivar were grafted on 5BB,1613 Couderc and 140 Ruggeri rootstocks by omega grafting machine. Grafted cuttings were planted and grown in plastic pots in a greenhouse. The callusing development and rooting performance of grafted cuttings, the final take of the first grade of the sapling and sapling itself, final take of potted grafted saplings, fresh and dry matter weight of shoot and root were evaluated. The existence of bud on base of rootstock and re-cutting of the base affected graft success positively. Re-cutting of 140 Ru rootstock of the base positively affected callusing and root development. Graft success ratios ranged from 71% (140 Ru, T-3) to 100% (1613C, T-2). Total final take ratios varied between 25% (140 Ru, T-3) and 90% (5BB, T-3) and the final take of the first grade ranged from 2.5% (140 Ru, T-2) to 37% (1613C, T-2,3,4). The existence of bud on the base portion of rootstock had a positive effect on final take and sapling quality parameters. As a result, existence of bud on the base of rootstock positively affected the graft success, shoot and root quality. Re-cutting of the base of the 140 Ru had a positive effect on graft success and final take ratios. In order to reduce the labour costs, there is no need to cut the base portion of 1613 C and 5BB rootstocks.

Chronic diseases progress slowly and generally cause symptoms in middle age onward. It is widely known that there is a close link between diets and chronic diseases in human. Foods which have specific target functions and preventive impacts on human health as well as their basic nutritional effects are defined as functional foods. These foods may decrease risk for chronic diseases due to having health preventive impacts on human health. Milk is an useful baverage for during childhood and adolescence because of its macro and micro nutrients. Milk composition is affected by mainly genetic, nutrition, season, lactation stage etc. Therefore, there are some differences in milk components between organic and conventional milk because of especially heredities of herds and nutrition. Seasonal variations in pasture, amount of grains and forages (fresh or conserved) cause changes in milk fatty acid composition of organic and conventional milk. Furthermore, organic production regulations limit the use of starch-based concentrates and supplements; therefore, some nutrients’ concentrations (protein, thiamine, vitamin B1 and B2, I etc) in organic milk may be expected to be lower than those of conventional milk. In this paper, organic and conventional milk components have been reviewed in term of functional milk.

Heat requirements in greenhouses are calculated considering greenhouse type, the climate of the region and temperatures desirable for plant growth. Calculations made according to daily average temperature values lead to misleading results during periods when temperatures are high and under conditions when greenhouse temperature is kept low. For this reason, determining heat requirements according to hourly values provides more accurate results. Calculations of heat requirements in greenhouses are based on the difference between the desired temperature in the greenhouse and the outside temperature. However, in unheated greenhouses and those that are not ventilated until a specific temperature, actual temperature values are higher than outside temperatures. For this reason, heat requirement calculations should be made according to hourly climate values taking into account actual temperature in the greenhouse and temperature rise resulting from greenhouse specifications. This study aims to compare the amounts of fuel consumed under real conditions with fuel consumption calculated with conventional methods using inside and outside temperature difference and considering the above mentioned inconveniences. Daily fuel consumption calculated theoretically differs from actual consumption values. However, in comparisons based on fuel amounts consumed on an annual basis, best results were obtained when temperature rise in the greenhouse was taken into consideration. In the event that temperature rise is taken into consideration, a 3% difference is observed between calculated fuel consumption and actual fuel consumption.

Star Ruby is the main grapefruit (Citrus paradisi) variety grown in Turkey; however, small fruit size is a common problem in ‘Star Ruby’ grapefruit. Fruit size is a decisive external quality parameter in citrus at the marketing of fresh citrus fruits. Fruit size can be enhanced by several techniques such as girdling and thinning. Various plant growth regulators are known to affect the growth and size of citrus fruit. The objective of the present study was to observe the effects of 2,4 dichlorophenoxypropionic acid-p (2,4-DP-P) on the fruit size, yield and quality of Star Ruby from 20-year-old trees budded on sour orange rootstock in Adana, Turkey in 2007. Four concentrations (50, 100, 150 and 300 ppm) of 2,4-DP-P were applied 8 weeks after anthesis during physiological fruit drop when the mean fruit diameter was 13-15 mm. The results indicated that the application of 2,4-DP-P increased the fruit size of Star Ruby grapefruit without reducing yield. The application had a significant effect on fruit yield except for trees treated with 50 ppm 2,4-DP-P. Compared with the control trees, applications of 2,4-DP-P increased the number of large, commercially valuable Star Ruby (>93 mm, 89-93 mm and 84-89 mm). No effects were determined on fruit internal quality parameters. Thus, the results of the present study revealed that 2,4-DP-P can be used to improve the fruit size of Star Ruby fruitlets during the June drop.

Hemorrhoids are swollen vascular vein pads in the upper part of the anal canal. The deformations in these tissues cause serious disturbances, and most important one is hemorrhoid, which is a symptomatic degenerative disease. Due to various etiologic factors, weakening and disintegration of connective tissue cause this disease. Many methods have been developed in the treatment of hemorrhoids from the past to the present day, and drug therapy is used as primary care. However, surgical treatment methods are applied in advanced stages in which the disease can not be treated with medication and when there is a life-threatening risk. As alternative medicine applications, herbal remedies have been used in hemorrhoid treatment for centuries. Prepared herbal mixtures or extracts are still frequently preferred by the patients today. In this context, in the research we have carried out in Beyköy village of Havza district; Teucrium orientale L. are used by regional people in the treatment of hemorrhoids and it was detected that the awareness of this herbal treatment is limited. In this study, the efficacy of T. orientale L. plant in hemorrhoid treatment was evaluated by conducting a questionnaire survey on the patients using plant extract. Of the approximately 500 patients using plant extracts, 89 agreed to fill out the questionnaire. Due to the results of the survey, it was found that all of the patients using the extract of T. orientale L. plant are healed partly or completely, and the benefit from the extract changed according to the patient's age and the stage of the disease. There has been no study on the use of this plant in the treatment of hemorrhoids in literature, and it is the first study to be done in this respect.

Lentil crop has largely been affected by global climate changing, particularly, due to rainfall and temperature changing and variability. Hence, the experiment was conducted in Central Highlands of Ethiopia, namely Akaki, Chefe Donsa and Bishoftu Agricultural Research Centre, in the 2009 and 2010 cropping seasons to assess the genotypic variation of lentil for growth and yield performances. Five lentil genotypes viz. 87S-93549 X EL-103-16, 87S-93549 X EL-103-9-1, Alemaya X FLIP 88-41L-02-AK-14, Alemaya X FLIP 88-41L-02-AK-6 were arranged in randomized complete block design with four replications at all locations. The result of study revealed that the genotype 87S-93549 X EL-103-9-1 produced the highest seed yield of 1985.90 and 2500.00 kg ha-1 during 2009 and 2010 cropping seasons, respectively, at Akaki. On the other hand, the genotype Alemaya X FLIP 88-41L-02-AK-14 gave the highest seed yield (4189.1 kg ha-1) at Chefe Donsa in 2009 cropping season. The genotype X FLIP 88-41L-02-AK-14 was found to be the earliest in physiological maturity, accounting 128.75 days, and the genotype 87S-93549 X EL-103-9-1 had yield advantage of 27.6% over the local check at Chefe Donsa in the 2010 cropping season. Generally, all lentil genotypes were performed better at Chefe Donsa, followed by at Akaki and Bishoftu locations during both cropping seasons. Rainfall and temperature conditions have enormous influences on the growth and yields performances of lentil genotypes at all research locations. The study inspires other studies to be conducted on other factors than climate events thwarting the production of lentil crops in the study areas.

In this study, the effects of Anatolian Black pine [(Pinus nigra Arn. subsp. pallasiana (Lamb.) Holmboe] plantation on hydro-physical soil properties and soil loss were investigated. This study was carried out on the afforestation field of Anatolian Black Pine in the Gölbaşı district of Ankara province, which is included in the arid and semi-arid regions. Totally 48 soil sample in two soil depth level (0-20cm, 20-50cm) were collected from forest (36 soil sample) and barren (control) area (12 soil sample). Hydro-physically important soil properties were analysed [Sand (%), Silt (%), Clay (%), Organic Matter (%), pH, Field Capacity (%), Wilting Point (%), Saturation (%), Available Water Holding Capacity (cm/cm) Saturated Hydraulic Conductivity (cm/hr), Bulk Density (gr/cm3)]. And soil loss in a unit area by using ABAG (Allgemeine Boden Abtrags Gleichung) model was estimated. Soil properties and soil loss amount relations among the land use group were determined. Topsoil (0-20cm) and subsoil (20-50cm) properties except subsoil organic matter were significantly affected by land use group. Finally, Significant changes were found for annual soil loss amounts in a unit area. Avarage annual soil loss in planted area was found approximately 5.5 times less than barren area at 0-50 cm soil depth. Vegetation factor (C) which is one of the most important components of the soil loss equation, has been significantly affected by afforestation in a short period of 40 years and thus it was a variable to reduce to soil loss.

One-year investigation is carried out aimed at evaluating all incomes and costs with a specific focus on the impact of feeding factors in 12 Holstein dairy farms (in total 284 cows) in Kosovo. The cost of on-farm produced feeds; the price of purchased feeds and the price of milk were used for the analysis. All costs created during this period are duly registered and considered in the analysis. Economic analysis showed that prices of on-farm produced feed were much lower (30 €/ton for silages and for hay). Average daily feed cost was 2.33 €/cow/day, while milk income was only 4.9 €/d. Individual feed groups contributed to total milk cost as follows: silages with 0.04 €/kg, dry roughages with 0.02 €/kg, and concentrates with 0.10 €/kg, while all other factors taken 0.13 €/kg of milk price. This study showed that feed was the largest farm expense making 68% of total farm costs.
