An Operations Research Application In The Particleboard Industry, Selman Karayilmazlar, Erdal Balaban

Turkish Journal of Agriculture and Forestry

In this study, a model was used for the optimization of product mix (the amounts of each product in the mixture) in particleboard industry by using linear programming. A theoretical model was constructed in which operations research methods and linear programming were applied to the maximization of the profit of a particleboard mill (KÖYKOBİR) as the consumer of industrial wood. To this end, 1993-1994-1995-1996 production, sales, stock quantities and costs as well as data related to capacities of the chipping, drying, pressing, sanding and gluing units were processed. Moreover, processing times of every product at these units were calculated. The …

Investigations On The Performance Of Some Strawberry Cultivars (Fragaria X Ananassaduch.) Grownin Open Fields And Under High Tunnel Conditions, Kubi̇lay Önal

Turkish Journal of Agriculture and Forestry

Five strawberry cultivars were grown as frigo seedlings planted in July by using two management systems, open grow-ing and high tunnel, in 1996 and 1997. Yield, earliness and some quality characters were observed. The high tunnel system made the crop 2-3 weeks earlier than the open field system with a longer period. Yield was also high in the high tunnel system with 1053 grams per plant while it was 877 grams in open growing. Miranda was the highest yielding cultivar in both management systems. Cultivars Camarosa and Miranda were superior for fruit weight and the rate of high quality.

The Effects Of Spiral Grain On Some Mechanical Properties Of Calabrian Pine (Pinus Brutia Ten.) Wood., Yener Göker, Nusret As, Turgay Akbulut, Türker Dündar

Turkish Journal of Agriculture and Forestry

The effects of spiral grain on some mechanical properties of Calabrian pine wood were studied. For this purpose, 17 sample trees were taken from Çakirlar region, Antalya district. The experimental trees were classifed into five groups according to the values of spiral grain angles as follows: 0- 5 % , 5-10 % , 10-15 %, 15-20 %, and > 20 %. No difference was found in bending strength and modulus of elasticity, up to 10 and 15 % spiral grain degrees, respectively. A spiral grain of 20 % or higher can be permitted in compression stresses. If wood has a spiral …

Estimation Of Inheritance Of Some Agronomical Characters In Common Wheat By Diallel Cross Analysis, Okan Şener, Mehmet Kilinç, Tacetti̇n Yağbasanlar

Turkish Journal of Agriculture and Forestry

This study was conducted to determine the genetic structure of a population which included six common wheat cultivars or lines and crosses of half diallel cultivars or lines. It was concluded that the epistatic effect was significant for a weight of 1000 grains and yield per plant, while the additive effect was significant for period of maturity, the number of spikelets per head, and the number of kernels per hear. The dominance effect was found in yield per plant. A partial dominance effect was found in other char-acters. It was found that at least 4 pairs of genes were effective …

A Study On Azolla As A Nitrogen Source In Rice Farming, Mi̇that Nuri̇ Gevrek

Turkish Journal of Agriculture and Forestry

This study was conducted to determine the best combination of azolla ( Azolla anabaena) and N fertilizer under Menemen ecological conditions in 1996 and 1997. The A. mexicana genotype of azolla was brought from the International Rice Research Institute (IRRI) and adapted to the Aegean region of Turkey. The results of study showed that the combination azolla+N fertilizer yielded approximately 356 kg/da of rice under Menemen second crop conditions. It was also concluded that the use of azolla will lead to a 1/3 reduction in the N demand of a rice crop.

Research On The Selection Of Hazelnuts Grown In Samsun, Taki̇ Demi̇r, Neri̇man Beyhan

Turkish Journal of Agriculture and Forestry

Performed in 1995 and 1996, the aim of this research was the selection of hazelnut types grown in Terme, Çarşamba, Salıpazarı and Ayvacık districts of Samsun province.

Effects Of Wood Species, Thickness And Cross-Section Factors On Wood Moisture Change Of Some Wood Species In The Indoor Climatical Conditions, Kemal Üçüncü

Turkish Journal of Agriculture and Forestry

The effects of wood species, thickness and cross-section factors on wood moisture content under centrally heated indoor conditions in Trabzon. Factors of thickness, cross-section and wood species were found to affect daily wood moisture content variation, but these factors did not appear to affect the average monthly wood moisture content. Strong relationship were found between average monthly wood moisture and wood equilibrium moisture contents (r 2 =0.9972), and wood moisture content, temperature and relative humidity (r 2 = 0.9926). According to climatical data for earlier years for indoor conditions in Trabzon, it was estimated that the average annual wood moisture …

Turkish Journal of Agriculture and Forestry

This study was conducted to determine the effects of different media, auxin types and concentrations on callus induction and plant regeneration from young inflorescences of 15 ecotypes of yellow bluestem ( Bothriochloa ischaemum). The young inflorescences were cultured on two different basal media (LS and SH) containing different concentrations (2, 4, 6, and 8 mg/l) of two different auxins (2, 4-D and Dicamba). The results showed that the ecotypes were significantly different from each other in callus induction rate, callus weight per dish and regenerate number per inflorescence segment. Depending on the ecotypes, mean callus induction rate varied from 9.7% …
