Assessing Crop Water Stress And Irrigation Scheduling In Cotton Through Use Of Infraredthermometry Technique, Berkant Ödemi̇ş, Ruhi Baştug

Turkish Journal of Agriculture and Forestry

Crop Water Strees Index (CWSI), based on canopy temperature which can be measured through use of an infrared thermometer, can be used to quantify crop water stress. However, the use of this index on farm level, require field tests for different crops. This study was carried out to evaluate the usage of CWSI for irrigation scheduling and predicting lint cotton yield under Antalya conditions. Soil water contents for different irrigation treatments were measured weekly and before each irrigation during the growing season. During the experiment, crop canopy temperature, dry and wet bulb temperatures and other climatic measurements were taken three …

The Effect Of Drought On The Growth And Yield Of Winter Wheat, Ali̇ Öztürk

Turkish Journal of Agriculture and Forestry

The effect of drought on the growth and yield of "Dogu-88" winter wheat variety was investigated in this field experi-ment using plot covers. Fully irrigated (FI), rainfed (R), early drought (ED), late drought (LD) and continuous drought (CD) treat-ments were studied under Erzurum conditions. ED decreased grain number per unit area by 44.4 %, 1000 kernel weight by 6.9 % and grain yield by 40.6 % compared with FI. A rapid senescence of green tissues in LD treatment also led to shorter green area duration (27.5 days), lighter 1000 kernel weight (3.8 g) and lower grain yield (24.0 %). CD …

Relationships Between Yield And Yield Components On Currently Improved Spring Rapeseed Cultivars, Hakan Özer, Erol Oral, Ünsal Doğru

Turkish Journal of Agriculture and Forestry

This research was conducted in Erzurum in 1991 and 1992 seasons using 14 spring oilseed rape ( Brassica napus ssp. oleifera L.) cultivars in order to investigate the relationships between yield and yield components by correlation and path analyses. Positive values were obtained in both seasons between seed yield and the characters: days to flowering, plant height, number of branch, number of pods per plant, number of seeds per pod, pod diameter, pod length, 1000-seed weight, and oil content. However, seed yield was significantly and positive correlated with only number of pod per plant and 1000-seed weight in both seasons. …

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 …

Turkish Journal of Agriculture and Forestry

In order to determine the effect of bleaching conditions on the physical and optical properties of pulps during the bleaching of CTMP with H_2O_2, 48 bleaching trials were carried out. After the analysis of the data obtained, the optimum bleaching conditions were as follows: H_2O_2 ratio 2.5-3%, Na_2SiO_3 ratio 3%, NaOH ratio 3%, NaOH/H_2O_2 ratio 0.75, MgSO_4 rate 0.5%, reaction temperature 70ºC, EDTA rate 0.5%, reaction time 80 minutes and concentration 16%. Brightness, breaking length, burst and tear index of CTMP bleached with H_2O_2 were found to be 51.42%, 18.03%, 92.50% and 13.20% respectively, higher than those of unbleached CTMP.

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 …
