This work was carried out to test whether germination of fifteen Lagenaria siceraria genotypes which were collected from western and southern parts of Turkey were improved by KNO3 and NaCl treatments. The experiment was conducted in two consecutive years, 2004 and 2005. Germination tests were performed at 15 0C and 18 0C. Results indicated that the effect of the treatments varied between the genotypes, temperatures and solutions that were used. KNO3 treatment was better and effective in larger number of lots than NaCl in both years. NaCl promoted germination in a few but inhibitive in large number of lots at both temperatures. As germination temperature was reduced, the positive effect of the KNO3 became greater. As a conclusion, priming treatments, specifically KNO3, appears to be promising in enhancing germination percentages of Lagenaria siceraria particularly at 15 0C that is the prevailing temperature in rootstock production for grafted watermelon seedling in unheated glasshouse conditions in early spring.

Key Words: Lagenaria siceraria, priming, germination, low temperature

This research was conducted to determine the effects of tobacco waste and straw incorporated to soil on urease activity and kinetics by an incubation experiment. For this purpose, clay loam soil sample and organic wastes were mixed until reaching 5% dry weight and this mixture was incubated in 25±0.5°C temperature for 30 days. Following incubation period, urease activity and changing of kinetic parameters were searched in soil samples in different substrate concentrations (0,1,2,4,6,8,10 and 12%), incubation periods (0,1,2,3,4,5 and 6 hours) and incubation temperatures (0,10,20,30,40 and 50°C). Research results showed that treatments of tobacco waste and wheat straw increased urease activity in soil. It was also determined that reaction velocity increased until the level of 8% substrate concentration for control and 10% for tobacco waste and wheat straw treatments. Then it did not change for both of them when exceeding these thresholds. The highest reaction velocity in all substrate concentrations was observed in 50°C incubation temperature for all soil samples including control. In all treatments, the highest Vmax and Km values were measured between 40-50°C. In addition, the highest Vmax/Km ratio for control and soil treated with organic wastes were observed in 50°C and 40°C, respectively.

The quality of the soil tillage and seedbed preparation depends on how well tillage equipment is designed and its purposed function. However, the abrasion and the deformation on tillage equipment are important factors that effect work quality in undesirable way. The deformed tillage tines and moldboard plough blades causes the soil to shift and in order to increase soil deformation energy as well as the tillage expenses. In this study, a three point hitched two unit moldboard plow as well as trapezoidal blades is used in two split plots where total is 60 decares. The amount of deformation on material loss from the plow blades were determined by using the image processing and weight loss determination together with the planimeter measurements. The Global Lab Image 2 Streamline software for trial version is used as image processing purposes. The mean material loss is determined as 33.6 g per decare by the use as the result of the weight loss of the moldboard blades. The mean material loss that is defined as the projection area of the blades is determined as 61.6 cm2 as the result of the image processing measurement of the moldboard blades. The mean material loss is also determined as 61.8 cm2 as the result of the planimeter measurement of the moldboard blades. It was found that the soil texture and the compaction had a great effect on the material deformation of the blades. On the other hand, the results of experiments show blades on the back units had less material loss compared with the blades on front units respectively.

Key Words: Moldboard plow blade, abrasion, image processing, soil compaction.

According to obtained result; callus induction was % 88.75 (Eliz 66) - % 98.75 (İba 99 Musaddak), callus weight was 0.7025 g (Temmuz 2) - 7.2179 g (Eliz 66), regeneration capacity was % 86.75 (Eliz 66) - % 98. 99 Musaddak), cluture efficiency was % 77.50 (Eliz 66) - % 97.50 (İba 99 Musaddak) and number of regenerated plants was 3.500 (İba 99 Musaddak) - 16.26 (Temmuz 2). In addition, when investigated relationships among traits; there was significant relationship between callus weight and number of regenerated plants (r = 0.674**). And also, regeneration capacity was effected as significantly by callus weight (r = 0.900**). Callus induction and regeneration capacity or their potential of the production process of trans genetic plant were investigated of some Iraqi common wheat varieties (which are resistant / tolarent to the drought, salt and some abiotic stress factors) in this research; and also, it was determined Irak variety is most favorable for this kind of studies.

Key Words: Wheat, tissu culture, Iraq, callus induction, plant regeneration.

Agricultural policy plays a major role in effective management of natural resources of a country. It is important that the acreage and condition of the various crop production sites, amounts and yields should be determined and forecast on time for a complete set up of agricultural planning. Otherwise, the development of agricultural policies in compliance with the realities of the country, and coinciding with development objectives beco me difficult. Most cereal production in the Anatolian Plateau is rainfed and therefore, exposed to the inter-annual variability of rainfall which directly affects the variability of the main cereals and food security as well. Yield forecasts were made by using AgroMetShell in the scope of FAO Technical Cooperation Project (TCP). Meteorological data, crop coefficients, phenological observations, soil characteristics and NDVI data are prepared in order to run the model. Model was run at 265 stations for unirrigated conditions. Water Satisfaction Index (WSI) values and graphics were obtained. By using NDVI data, average values of WSI calculated city by city. Statistical analysis were made between WSI values and statistics. As a result yield forecasts of cities were obtained for wheat in 2005 and 2006. Maps were prepared by using statistics and yield forecasts for 2005 and 2006. A relation of r ² = 0.9067 calculated between yield forecasts and statistics.

Ants interactions with Coccoidea(Hymenoptera: Formicidae) Species (Hemiptera: Sternoryncha)
(Turkish)

The ants and Coccoidea (scale insects) species that produce honeydew have diverse and interesting relationships. The ants use these Coccoidea as the source of carbohydrate, protein and lipid while the coccoids take advantage of being transported to new plants by ants so that they protect themselves from changing climate conditions and from their natural enemies. The presence of ants on the plants has two important effects; it increases the population of scale insects and increases the general well-being of the plants by hunting the pest on plant. The extermination of ants or ignoring the harmful effect of pesticides on ants during pesticide treatment results in the significant increase in the population of other pests on the plant. The floristic and/or structurally complex ecosystems may intrigue the ants tended to honeydew. The mutual relations between ant and scale insects in poly-cultural environments should be considered more seriously than in mono-cultural environments during pest management.

Key Words: Ants, Coccoidea, Hemiptera, natural enemies, honeydew
