Factors Affecting Iron Chlorosis Observed In Peach Trees In The Bursa Region, Haluk Başar
Factors Affecting Iron Chlorosis Observed In Peach Trees In The Bursa Region, Haluk Başar
Turkish Journal of Agriculture and Forestry
This research was implemented to determine the factors causing iron chlorosis observed in peach trees in the Bursa region. For this purpose, four peach orchards having trees with various degrees of chlorosis were selected. Soil and leaf samples were collected during a two year period. According to the results, chlorophyll, total Fe and active Fe contents of the leaves were negatively correlated with soil pH and lime (CaCO 3 ) and the active lime content of the soils. Significant positive correlations were found between organic matter content of the soils and chlorophyll, total Fe and active Fe content of the …

Effect Of Some Plant Growth Regulators On Fruit Thinning In Apricots, Mehtap Coşkun, Ahsen Işik Özgüven
Turkish Journal of Agriculture and Forestry
This study was carried out during 1995-1996 in Çukurova. In the experiment, Priana and Belliana were used as comparative cultivars. In addition, 12.5, 25, 50 ppm of NAA and 500, 1000, 2000, 4000 ppm of carbaryl and 50 % of hand thinning were applied about three weeks after full bloom. The results showed that 50 ppm NAA increased both the thinning rate and the fruit size while 1000 and 2000 ppm of carbaryl had a positive effect on the fruit size and weight without having any effect on thinning. Although the treatments gave better results on the fruit size and …
Exploring The Concept Of A Forest Landscape Management Paradigm, Emi̇n Zeki̇ Başkent, Haci̇ Ahmet Yolasiğmaz
Exploring The Concept Of A Forest Landscape Management Paradigm, Emi̇n Zeki̇ Başkent, Haci̇ Ahmet Yolasiğmaz
Turkish Journal of Agriculture and Forestry
The concept of forest management planning has rapidly progressed towards a more holistic approach in the last decade. Considering the whole landscape of ecosystems is the focus of landscape management. This paper examines the evolutionary process of forest management and compares and contrasts the landscape management planning concept to its predecessor, the conventional forest resource management approach. It explains the conceptual framework, provides the principles and the improvements over the conventional management planning, and discusses different approaches towards the landscape management concept. However, the paper stresses the fact that the evolutionary process of forest management provides the basis for what …
Impacts Of Turkey's Integration Into The European Union On Agriculture In The Post-Uruguay Round Environment, Cemal Atici, P. Lynn Kennedy
Impacts Of Turkey's Integration Into The European Union On Agriculture In The Post-Uruguay Round Environment, Cemal Atici, P. Lynn Kennedy
Turkish Journal of Agriculture and Forestry
Agricultural trade policies between Turkey and the European Union are modeled using a political preference function (PPF). The PPF is used to estimate the producer and consumer weights perceived by policy makers. The agricultural effects of Turkey's integration into the European Union (EU) and optimal strategies for Turkey and the EU are analyzed Results show that Turkey' s PPF values will be lower, with respect to agriculture, when it joins the EU; however, EU trade liberalization benefits Turkey.
Comparison Of The Swelling And Shrinkage Characteristics Of Corcisan Pine (Pinus Nigra Var. Mantima), İlker Usta, Ari̇f Güray
Comparison Of The Swelling And Shrinkage Characteristics Of Corcisan Pine (Pinus Nigra Var. Mantima), İlker Usta, Ari̇f Güray
Turkish Journal of Agriculture and Forestry
The objective of this study was to determine the volumetric swelling and shrinkage characteristics of air-dried Corsican pine in the longitudinal, tangential and radial directions. For this purpose, the swelling of the wood was caused by the wood being increased in water whilst placed in a swelling jig, and the shrinkage made in an oven by drying. The experimental results showed that although the differences in swelling or shrinking occur in the first 5 hours, both swelling and shrinkage are then negligible in the three directions. The values of swelling-shrinkage showed considerable difference among different directions; for instance, swelling-shrinkage in …

Turkish Journal of Agriculture and Forestry
This study was conducted to investigate the effect of vesicular-arbuscular (VA) mycorrhizae on plant growth of cucumber. Yayla F 1 seeds were sown in sterile and non-sterile growing medium (organic manure:soil:mix of sand; v:v:v 1:1:1). The mix inoculum of Glomus mosseaand Glomus fasciculatumspores (10 g/plant) was placed 5 cm below the cucumber seed before sowing. In order to investigate the effects of VA mycorrhizae on plant growth, plant height, diameter, number of nodes were measured every 15 days. Also once a month biomass, P, Zn and Mn content of dry matter biomass and mycorrhizal infection were also determined. The results …

Mafic Microgranular Enclaves In The Kozak Granodiorite, Western Anatolia, Cüneyt Akal, Cahi̇t Helvaci
Turkish Journal of Earth Sciences
Enclaves which are relicts of initial basic magma give important information on the origin and evolution of granitic magmas. The mafic microgranular enclaves from the l-type Kozak pluton are less than 1 m that are located at the margin of pluton and mostly less than 15 cm and are generally in sharp contact with the surrounding granodiorite. In some cases, several enclaves may occur close to each other, but they are not closely clustered to form swarms. Most of the enclaves are ellipsoidal in shape. The largest enclaves are less ellipsoidal with curved boundaries. The mafic microgranular enclaves contain same …

Turkish Journal of Agriculture and Forestry
This study was carried out to determine the shear and bending strength of different end-to-end grain joints, which were glued with PVAc (polyvinyl acetate). For this reason, specimens, prepared from scotch pine (Pinus sylvestris l), were made with three types of end to end grain joints namely: half-lap, mortise and tenon and double mortise-and-tenon. End-to-end grain of half-lap joints gave the highest strength in shear (2.385 N/mm 2 ) and bending (0.540 N/mm 2 ) experiments.
