This study was conducted to determine the corn cultivars growing for silage production as second crop in between 1996, 1997 and 1998 years in condition of Kazova-Tokat. 13 corn cultivars which had been obtained from different sources were used in these trials. In the research, plant height, plant composition (% leaf, stem and ear or head ratio), fodder yield and dry matter yield were determined. The results of variance analyses showed that there were statistically significant differences among cultivars for all characters. The highest fodder yield (10558.3 kg/da) was obtained from RX-947 and the lowest fodder yield (7720.0 kg/da) was obtained from P.3167. Plant height, leaf ratio, stem ratio and ear ratio of varieties changed between 203.8-283.3 cm, 14.3-21.3 %, 57.1-65.2 % and 15.7-26.3 %, respectively. While the lowest ear yield (1417.2 kg/da) was obtained from LG-60 cultivars, the highest ear yield (2745.5 kg/da) was obtained from RX-788 varieties.

Department of Agricultural Economis Faculty of Agriculture University of Ankara

The purpose of this study is to measure and to analyze the efficiency of cotton production activities on cotton producing farms. The goals of this study were focused on assessing data envelopment analysis, and on the technical and scale efficiency of cotton-production activities. One hundred and sixty-five representative cotton-producing farms were selected in the Söke Valley through a stratified random sampling method and then the relevant data were collected on the production activities of these selected farms. According to data envelopment analysis carried out considering all inputs, the number of farms found to be technically efficient was 20. The average technical efficiency of the 165 farms was calculated to be 83.90%. Differences between average efficiencies of the cotton-producing farms were evaluated using the Kruskal-Wallis test. All efficiency measures of the small-sized farms except for scale efficiency were found to be statistically different from farms of other sizes. When farms were grouped according to the educational levels of their owners, technical and pure technical efficiency measures were observed to be higher for farms whose owners were university graduates, but scale efficiency was found to be higher on farms owned by high school graduates. Nonetheless the differences in these efficiency measures grouped according to educational levels were not found to be statistically significant. When efficiency measures are assessed in terms of the location of the farm settlement, technical and pure technical efficiency measures are observed to be greatest in urban locations, while scale efficiency was higher in the villages. Statistical comparisons showed no significant differences between technical and scale efficiencies according to settlement location, but significant differences were found in pure technical efficiency measures.

Key Words: technical efficiency in cotton production, scale efficiency, data envelopment analysis

The aim of this study is to determine some slaughter and carcass characteristics of Akkeçi (White goat-Saanen x Kilis Bı) kids 6 month old and fed ad-libitum by different forms of barley. Each group containing 5 kids weaned 2 month age received grain (GI), cracked (GII) and crushed (GIII) barley separately, for 4 months of growing period. Slaughter weight, warm and cold dressing percentages in GI, GII and GIII were found as 30.48±1.38 kg, 47.18±1.74 % and 45.28±1.28 %; 28.45±1.64 kg, 47.41±1.29 % and 45.35±1.37 %; 26.28±1.71 kg, 45.01±1.27 % and 43.32±1.38 % respectively. Although the difference were not statistically significant between groups, internal fat and kidney-pelvic fat were higher in the kids fed with grain and cracked barley. Internal fat percentage in the slaughter weight was 1.51±0.14 %, 1.63±0.21 % and 1.25±0.16 % in GI, GII and GIII respectively. The kidney-pelvic fat percentage in the cold carcass weight was also 5.83±0.98 %, 5.94±0.39 % and 5.35±0.58 % respectively. The portion of valuable parts in the left-half carcass were found fore-leg; 20.41±0.24 %, 22.10±0.49 % and 22.32±0.42 %, hind-leg; 32.27±1.28%, 32.41±1.03 % and 33.32±1.01 %, back-loin; 23.03±1.38 %, 23.04±0.96 % and 22.96±0.46 % respectively. It was also found respectively, 54.60±2.822 %, 57.03±1.757 % and 54.44±3.050 % for muscle; 28.20±3.150 %, 24.98±1.511 % and 26.64±1.668 % for bone and 21.70±1.167 %, 11.70±1.369 % and 13.95±1.909 % for total fat following physical dissection of tissues in the 6th-12nd ribs (rack).

(Turkish)

Suzan ALTINOK
Ankara University, Faculty of Agriculture, Department of Agronomy-Ankara

In this research which was carried out at the experimental field of Agronomy Department of Agricultural Faculty on Ankara University, on the growing season of 1999-2000, hairy vetch (Vicia villosa L.) line of L-626, narbonne vetch (Vicia narbonensis L.) line of L-1025 and barley (Hordeum vulgare L.) cultivar Tokak 157/37 were used as materials. In the research, two vetch species were grown as monocropping and at different mixture rates with barley. All of those mixture rates were; 1) 100% monocropped hairy vetch, 2) 80% hairy vetch+20% barley, 3) 60% hairy vetch+40% barley, 4) 40% hairy vetch+60% barley, 5) 20% hairy vetch+80% barley, 6) 100% monocropped barley, 7) 100% monocropped narbonne vetch, 8) 80% narbonne vetch+20% barley, 9) 60% narbonne vetch+40% barley, 10) 40% narbonne vetch+60% barley, 11) 20% narbonne vetch+80% barley. The plots where different mixture rates were placed on were harvested when the barley was on milk stage for silage and plants were wilted, chopped and filled into 2 liters of jars without having any air. Some forage samples were dried under the sun after harvesting. Some physical observations, dry matter and pH measurements were done on silage samples and flieg scores were calculated after 25 days. Apart then, on the samples of hay and silage, crude protein contents were calculated by the means of dry matter. At the result, the most quality silages were obtained from the mixtures which have more barley ratio than others on monocropped hairy vetch and narbonne vetch and their mixtures with barley. However, according to the all physical observations and flieg scores, the best, good and medium quality silages were obtained from vetch+barley mixtures and their monocrops except monocropped hairy vetch and the mixture of 80% hairy vetch + 20% barley. Another result of this research when the comparison of crude protein contents, narbonne vetch+barley mixtures gave the more positive results in terms of ensiling them then making hay.

As a result of the reconstruction efforts following Turkish Republic, in capital city Ankara, an open-green space system has been formed. The most crucial parts of this subject system were the embassy areas that are within Kavaklidere-Çankaya valley region and which are subject of our research, the garden of the Presidency and main parks. In these areas that are accepted as natural preservation areas by Ministry of Culture in 1974 and also have high importance for the history of our Republic, we can observe rare tree species which have survived through years. In the research we have not only defined the rare trees but also these trees have been classified in accordance with the field researches applied in their various vegetation periods as well as their habitus characteristics during two years. By the clarification of rare and not commonly used tree species, the main aim is to introduce these tree species and enable people to use them in their landscape projects so as to increase the variety of trees used in parks and gardens. At the same time, the level of how the embassy gardens express about their own culture, was tried to be expressed via this project.

Gaziomanpaşa Üniversity Faculty of Agriculture, Department of Farm Strucures and Irrigation-Tokat

The main purpose of this study is to determine the best suitable probability distribution for the daily extreme flows of Kelkit stream. In this study, the daily flow values measured from 1938 to 1988 in the flow station numbered 1401 which is operated by General Directorate of Electric Power Research Survey and Development Administration (EIE) were used. The daily extreme flows among daily flows for each month and each year were selected. Since reserving water by Kılıçkaya dam built on Kelkit stream had been started after 1988, the daily flows, that came after this date were not taken into account for homogeneity. To determine a suitable probability distribution for daily extreme flows, normal, log normal, three parameter log normal, two parameter gamma, Pearson type III, log Pearson type III, extreme value type I, three parameter Weibull distributions were used. The selected maximum daily flows of each month were fitted better to, Pearson type III for the second, fifth and tenth months; log Pearson type III for the first, eleventh and twelveth months; log normal for the third, seventh and eighth months; three parameters log normal for the fourth and nineth months and extreme value type I for the sixth month. The minimum daily flows of each month were fitted better to, three parameter Weibull for the first, second, nineth and tenth months; three parameter log normal for the third, fourth and eleventh months; Pearson type III for the fifth and sixth months; extreme value type I for the seventh month; normal for the eighth month and log normal for the twelveth month. The daily extreme flows for each year were also fitted better to Pearson type III distribution.

This research was carried out in West Pond which supplies water to the Sakaryabaşı Fish Culture and Research Station. Calcium levels were determined in water and sediment samples taken from the station in the hard water eutrophic pond in 2000 (july, october), 2001 (january, april). Pond's sediment had a high calcium level (276,23-297,67 µgg-1 dw) and pond water calcium concentrations (59,75-80,25 mg l-1) were higher than overlying and porewater calcium. The lower level of total filtrable orthophosphate in pond water than that of porewater could be explained by coprecipitation of phosphate with calcium. The effects of pH and water temperature on the exchange of phosphorus between water and sediment were also discussed.

Key Words: Sakaryabaşı West Pond, calcium, total filtrable orthophosphate, sediment, pH
