Shear And Bending Strength Of Some End To End Grained Jointsprepared From Scotch Pine, Hani̇fi̇ Tokgöz, Ayhan Özçi̇fçi̇, Musa Atar, Burhanetti̇n Uysal
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.

Determination Of Yield And Quality In Marjoram As Influenced By Development Periods, Menşure Özgüven, Sezen Tansi
Turkish Journal of Agriculture and Forestry
Marjoram, naturally grown in Mediterranean region, is a perennial shrub. It is used as spices, and its essential oil has also antimicrobial and antibacterial properties. Marjoram is well-adapted to Çukurova conditions, so, the highest fresh (1077.2 kg/da) and dried herba yields (492.9 kg/da) and essential oil yield (7.77 l/da) were obtained at post-flowering stages. The determined main components of its oil were \gamma-terpinen, p-cymol and terpineol. The contents of geraniol, p-cymol and cineol were found to be influenced by only development stages while sabinen, myrcen, borneol, terpineol, thymol and carvacrol contents were influenced by both development stages and experiment years.

Examining Statistical Sufficiency Of Rainfall Intensities At Standard Times Of Adana, Ali̇ Yücel, Fati̇h Topaloğlu, Kazim Tülücü
Turkish Journal of Agriculture and Forestry
Hydrological and meteorological events are effected from different factors. Their values in future can only be determined by probability and statistical laws because rainfall intensities at standard time occurring under different eftects are random character. However, these values not being random character can not be used in their present situation in system simulation, frequency analysis, watershed amelioration, drainage studies, urban settlement planning, etc. In this study, it is aimed to examine some statistical analysis techniques thought to be helpful in deciding sufficiency of rainfall intensities at standard times in studies in questions. Depending on this aim, 14 rainfall intensities at …

Effect Of Fallow, Winter Lentil, Nitrogen Fertilization And Different Soil Tillage On Wheat Yield In The Dryfarming Areas Of Central Anatolia, Di̇dar Eser, M. Sai̇t Adak, Andreas Biesantz
Turkish Journal of Agriculture and Forestry
This research was carried out in two different dryfarming areas of Central Anatolia (Haymana-Ankara and Gözlü-Konya) to detect the effect of fallow and winter lentil and different tillage systems on wheat yields. According to experimental results of two crop rotation cycles, wheat yields after fallow or after lentil respectively, were in the same statistical group (i.e. no significant difference), in spite of a neglectible reduction of yield after lentil in comparison to wheat yield after fallow in Haymana. In this case it could be proved that sowing of winter lentil was more profitable instead of implementing fallow before wheat. In …
