This research was conducted at uruş subdistrict, Beypazarı district of Ankara in 1996. The variety of winter lentil named Pull-11 was used as seed material, and also Rhizobium leguminosarum and Pursuit 100 SL were applied as inoculant and herbicide, respectively. The interaction between inoculation methods and the different time herbicide applying was significant statistically in characteristics of plant height, plant weight, number of pods, pod weight, 100 seed weight, harvest index and yield except number of seed Per plant, and seed weight Per plant. According to results of the research; the value of characteristics investigated in plots done inoculatiion were higher than in plots done no inoculation. The yield increased with inoculation. Herbicide (Pursuit 100 SL) used for weed control in lentil have caused significant differences according to applying times of herbicide. The best results were obtained first applying time that was after sowing. The third applying time, application of herbicide which is tdone in the beginning of blooming gave the lowest values and caused negative effects.

Key Words: lentil, Rhizobium, inoculation methods, herbicides

Ankara University, Faculty of Agriculture, Department of Farm Structures and Irrigation-Ankara

In this study, the evapotranspirations of sunflower (Helianthus annuus L.) in the Experiment Farm of the Agricultural Faculty, University of Ankara, were measured during the years of 1994 and 1995, and the measured values were compared with the values calculated by some estimating methods of evapotranspiration. As a result, the most reliable estimation methods of evapotranspiration which could be used for irrigation scheduling of sunflower were found as Christiansen-Hargreaves pan evaporation and Jensen-Haise methods.

Ankara University, Faculty of Agriculture, Department of Farm Structures and Irrigation-Ankara

The aim of this study was to investigate sprinkler irrigation applications in Nevşehir-Derinkuyu and Kaymaklı region. By this aim questionnaire was achieved with 125 farmers performed sprinkler irrigation. Irrigations systems and irrigation applications were evaluated in 25 farms represented site conditions, considering questionnaire results. Sprinkler irrigation systems investigated were situated considering land situation and shape on whole farm units, but, 24 % of which were not operated in convenlent operating pressure and sprink space, and in 40 % of which radius of main and lateral lines were not selected convenlently. Generally excessive irrigation water was applied. However irrigation applications were not enough to meet crop water requirement during total growing season and not to suffer from stress lack of water. Moreover the IRSIS computer sofware was used to evaluate existing irrigation applications and optimum and practice irrigation schedules were recommended for site conditions.

The effect of P. vera L., P. atlantica, P. khinjuk and P. terebinthus species pollens on fat content and fatty acid composition of Siirt, Ohadi, Kırmızı, Halebi and Uzun cultivars grafted on P. vera L. was investigated. Statistical analysis showed that pollen source did not has significant effect on fatty acid compositions of pistacia kernels. Otherwise, pollen source had significant effect total fat content in Uzun, Halebi and Ohadi cultivars. While the highest fat content was determined in Uzun and Halebi cultivars pollinated with P. vera pollens in the first year of this experiment, kernels obtained by pollination with P. atlantica and P. khinjuk pollens had higher fat content in the second year.

(Turkish)

Gönül YILDIRIM and Tümer URAZ
Ankara University, Faculty of Agriculture, Department of Dairy Technology-Ankara


In this study, effect of using GDL on some properties of white pickled cheese was investigated. Raw milk was divided into three equal parts and cheese samples were manufactured by adding GDL without starter culture at the levels mentioned below (A: 0.0 % GDL (control), B: 0.2 % GDL, C: 0.5 % GDL). Total solids, fat, total nitrogen, titratable aciditiy and pH values in raw milk were determined in cheese samples total solids, fat, salt, total nitrogen, water soluble nitrogen, non-protein nitrogen, tyrosine, total volatile fatty acids, titratable acidity pH and penetrometer values were analyzed. Additionally counts of total bacteria and sensoryp properties at the 30th, 60th and 90th days of storage were determined. Cheeses made by using GDL were softer than the control cheese. Also samples with 0.5 % GDL had weak and creamy consistency after the 30th day of ripening. Organoleptic scores of cheeses made by GDL were lower than that of the control cheese. In all samples flaviour defects were determined.

The effects on performance, egg and blood parameters of supplementation at the levels of 0.00 %, 0.15 %, 0.30 %, 0.45 % ascorbic acid to corn- soyabean meal based rations were investigated. Diets were formulated isocaloric and isonitrogenic.In the research füor the groups feed efficiency, initial and final weight, egg weight, sheel ratio, sheel centre and stubby thickness, average shell thickness, albumen length and height, yolk height and width, broken or crack egg, ortality, serum ascorbic acid and calcium were not found statically different (P<0.05). However, egg production, feed consumption, sheel resistance, sheel sharp thickness of control group were lower than other groups. Differences were not significant (P<0.05). Albumen width of control group was found statically higher than 4th group including 0.45 % ascorbic acid (P<0.05). As a results of experiment, supplementation of ascorbic acid can not be recommended up to 0.45 % in layer rations for blood parameters, egg production, feed consumption, sheel resistance and shell sharp thickness, in 17-31oC.

Total number of 36 Lactobacillus strains were isolated and identified from cecum in our previous study. Some properties of those strains were determined. These properties were lactic acid production, proteolytic activity and antibacterial activity against pathogens. It was determined that lactic acid productions ranged from 2.200 to 6.800 mg/ml, and proteolytic activity ranged between 0.013 and 8.600 mg tyrosine/5 ml. Strains with high proteolytic activity produced less lactic acid than the others. Beyond that 25 strains inhibited E. coli K12 107 and S. typhimurium 60-62 at different levels. It was found that S. typhimuriu 60-62 was inhibited more than was E. coli K12 107, and the most effective Lactobacillus strains were L. fermentum KY2002 and L. plantarum KY2402.

This study was carried out at the experimental field and in the greenhouse of Field Crops Department. Faculty of Agriculture, University of Ankara in 1993 year. Experiments were conducted in splik plots in randomised plots design with four replications. Cutting were treated with IBA, IAA and NAA at 100, 250, 500 and 1000 ppm concentrations with 6 and 12 hours periods to induce rooting. The highest rooting rates in C. ovata (41.0 %) was achieved by treating the roots with 500 ppm IAA for 12 h and 500 ppm NAA for 12 h (29.5 %) in the experiment carried out in April.
