ODC: 114.445.1:114.445.2:176.1 Populus
Author: TUNCKALE, I.H.
The municipal populetum, established in spring 1962 near by the Tacin nursery, was planted with clones of Populus nigra. During the following years almost all of the saplings were decayed. In 1965 summer to investigate the causes of death of the plants at populetum mentioned above, forty soil samples were taken from thirteen soil profile ditches excavated in different plots such as from the places of alive and decayed plants. After the statistical control of the soil analysis it was found significantly differentiation between ESP and boron at the plots of alive and death saplings and the cause of decay is imputed on the high amounts of exchangeable sodium percentages (ESP) and boron.
2) AN INVESTIGATION ON A POPLAR PLANTATION INFLUENCED BY SALINE WATER TABLE
ODC: 114.53:176.1 Populus
Author: TUNCKALE, I.H., OZ, C.
Location of the plantation area is 1.2 km far from the sea, in Izmit. This plantation was established at the end of 1966 and 2000 saplings of P.x euramericana "I-214" in two years old were planted. However, growth of the plantation was remarkably satisfactory during first vegetation period in 1967, but it was completely parished on July of second vegetation period by the effect of severe salinity and alkalinity caused by irrigation water allowed to run. According to analysis carried out on water table and soil, both the salinity and also alkalinity are arisen due to saline water table only. The ions of Na+ and Cl- included by water table are in toxic level for poplars. Symptom was a chlorine blight which caused the fall of leaves.
3) INFLUENCE OF NPK MINERAL FERTILIZERS ON HEIGHT GROWTH OF YOUNG P. RADIATA AND P. PINASTER Ait. PLANTINGS
ODC: 232.322.41 Pinus
Author: TUNCKALE, I.H.
Different rates of N, P, K and Ca mineral fertilizers were applied to the seedlings 1, 2 and 4 years old in the plantation area Izmit-Işiktepe. The best result were obtained from the nitrogen fertilizers. The other fertilizers such as superphosohate and potassium sulphate alone had no effect on practical height growth. Among the NPK mineral fertilizers NK and NP were found to be most effective combinations. Nitrogen fertilzer resulted in an increase of 10 % in height growth for the first two years of the plantation. An older ages as the same fertilizer has shown only 4-5 % increase in the height growth. Fertilizer effect on height increment was parallel to that in height growth. However, the increment was not very pronounced.
4) INVESTIGATION OF MINERAL FERTILIZATION ON GROWTH RESPONSES IN THE POPLAR NURSERIES
ODC: 232.425.2:176.1 Populus
Authors: TUNCKALE, I.H., SEMIZOGLU, M.A., TOLAY, U.
To determine the influence of mineral fertilizers on the growth of P.x euramericana experiments were established with clone "I-214" in Izmit and Torbali and Populus nigra Tr. "56/52" in Ankara nurseries. 200-400 kg/ha N in Izmit, 400 kg/ha N and 600 kag/ha P in Torbalı showed the best growth on P.x euramericana "I-214". Non significant results were obtained in Ankara on P. nigra Tr. "56/52".
5) THE EFFECTS OF AMMONIUM NITRATE ON GROWTH OF I-214 POPLAR PLANTATIONS
ODC: 232.322.4:176.1 Populus
Author: GÖKÇE, O.
The experiment was designed to determine the effects of ammonium nitrate (%26 ) on poplar plantations with three replications and 4 treatments. Ammonium nitrate was given in April, May, June in 1973, 1974, 1975 with three rates, 225 kg/ha, 300 kg/ha, 450 kg/ha. Result showed no significant effects of fertilizer an diameter and height growth.
6) AN INVESTIGATION ON THE INFLUENCE OF N.P.K. FERTILIZERS ON E. CAMALDULENSIS GROWTH IN NORMAL SOILS
ODC: 232.425.1:176.1 Eucalyptus
Author: AKYILMAZ, M., DEMIRTAS, M.
The experiment was established at Karabucak-Tarsus with complete block design, 4 replications in 1970. Treatments were control, N, P, K, NP, PK, NK, NPK. P showed positive effects on height growth. Combinations have no effects on growth. P showed its effects three years after planting.
7) A STUDY ON SITE EVALUATION AND MAPPING USING BLACK AND WHITE AERIAL PHOTOGRAPHS
Author: HIZAL, A.
Black and white infrared serial photographs with an average scale of 1/20.000 used in this study. 41 soil pits were distributed in the study area where the soil forming factors different. These soil profiles were sampled according to the standard soil sampling procedure by taking loose and bulk density samples at the following depths; 0-20 cm 20-40 cm, 40-60 cm and 60-80 cm, furthermore 80 loose samples of topsoil were taken for determining some properties of the topsoil. Data obtained from serial photo-interpretation and field-laboratory work were evaluated by regression and correlation methods. Consequently, significant correlation and regression between gully density and topsoil frictions showed that texture and organic matter content of the topsoil can be estimated by interpretation of gully density on serial photographs. Besides, the determinations of gully shapes on the photographs gave a reasonable opportunity to differentiate the fine and coarse textured soils.
8) AN INVESTIGATION ON EFFECT OF THE FIVE DIFFERENT AMOUNTS OF NITROGEN FERTILIZER ON THE GROWTH OF P. RADIATA AND P. PINASTER YOUNG PLANTATIONS
ODC: 237.4:174.7 Pinus
Authors: TUNCKALE, I.H., OZ, C., HIZAL, A.
The experimental area is in the Cenedag plantation area located in Kocaeli peninsula. Diameter and height growth of the young trees of P. radiata and P. pinaster were effected by the several amounts of amonium nitrate. Because, the soil of the experimental area included adequate amounts of mineral fertilizers for the seedlings. Result obtained by the research confirmed that fertilizing is not profitable unless it is not required for soil.
9) THE EFFECT OF LAND CLEARING BY PRESCRIBED BURNING ON THE PHYSICAL AND CHEMICAL SOIL PROPERTIES OF REFORESTATION AREAS IN KOCAELI PENINSULA
Authors: HIZAL, A., SARIBAS, M.
Location of the area of trial is near the village of Bahcecik in Izmit. The experiment was established in accordance with 2 x 2 x 2 factorial randomized block design. After burning the vegetation on the blocks, soil samples were taken from three different soil depths (0-10 cm, 10-20 cm, 20-30 cm) so that natural structures of the samples were kept. Following results were obtained from the investigations at the trial area and laboratory analysis of the soil samples: Soil temperature at the depth of 30 cm was between 3oC-39oC after burning. The litter on the surface was burned up to 7.5 cm depth. Decrease on soil moisture was between 0.7 %-3.5 % average. There was not any significant effect of fire on pH and permeability and the amount of potassium and phosphorus. But decrease was observed at the amount of sodium and water retention capacity. The organic soil layer was mainly influenced by prescribed burning. The mos convenient time for this application is early spring.
10) AN EXPERIMENT OF FERTILIZATION WITH N.P.K. AND GREEN MANURE ON EUCALYPTUS CAMALDULENSIS DEHN. PLANTATIONS ON SAND DUNES
ODC: 232.322.41:232.322.43:176.1 Eucalyptus
Author: AVCIOGLU, E., SUN, O., GURSES, K.
An experiment was established at Turan Emeksiz-Tarsus and Akyatan-Adana
sand dunes to observe the effects of N.P.K. fertiliser and manure on E.camaldulensis
In the experiment; different combination of N.P.K. and rye oats, wild watch, kidney beans were used as green manure. Treatments were repeated three years. The results listed below were obtained at the end of 6 years.
CaCO3 had positive effect on diameter and height growth of E. camaldulensis on sand dunes.
The fertilisers and manure treatments showed no significant effect on diameter and height growth of E. camaldulensis plantations.
The treatments of N.P.K. repeated three years showed better results one and two years applications.
