Importance of organic agriculture has been increased by developing of consumer's conscious in recent years. In this study, the effects of different organic applications on yield and some quality parameters of Camarosa and Fern strawberry cultivars were investigated. This research was conducted at Ankara University Faculty of Agriculture Ayaş Horticultural Research Centre during 2002-2004 years. Frigo seedlings of Camarosa and Fern strawberry cultivars were planted in July. Yield and some quality parameters of plants grown under different organic applications performed in different plots were determined. The highest yield values were obtained from Green manure+farmyard manure+humic acid+foliar fertilizer application (Fern: 177,07 g/plant, Camarosa: 133,9 g/plant). As a result, Green manure+farmyard manure+humic acid+foliar fertilizer application can be suggested to organic strawberry growers in Ankara ecological conditions.

In this research the transformation of rainfall into runoff was simulated using two dimensional SV equations in the Kamanaj watershed, a subwatershed of Ajichay river, located in East Azarbaijan Province, Iran. Rainfall-runoff was simulated based on a diffusive model by considering momentary infiltration rate for temporal and spatial analysis. SV equations were solved using explicit method of finite difference numerical technique as the initial and boundary conditions were defined. For this purpose, the watershed area was divided into a grid size of 250m×250m by the tools of GIS leading to prepare digital elevation map. Kostiokov infiltration, as the best fitted model, was selected to measure infiltration data and applied in SV equations. Three hydrographs were used to verify the model. Comparison of the simulated and observed hydrographs verificated the capability of model in simulating the rainfall-runoff. The presented model can be used for determination of runoff from momentary rainfall with consideration of temporal and spatial variation of infiltration over the watersheds.This model can also be used to forcast the peak discharge and time to peak in watershed outlet.

Key Words: Diffusive model, Rainfall-runoff, SV equations

The leaf shape, size, area and number of leaf per plant of cotton are factors which effect seed yield via photosynthetic activity. In the study, the four cotton cultivars, two normal leaf shape and two okra leaf shape, were used as material. The number of leaf, mean of individual leaf area, leaf area index, leaf chlorophyll content, plant height, number of monopodial and sympodial branches and cotton seed yield were investigated. The coefficient correlation between cotton seed yield and all characters was analyzed. The normal leaf shape cultivars were the higher than okra leaf shape cultivars for mean of individual leaf area, leaf area index, plant height, number of sympodial branches. The highest chlorophyll content (50.54) was for Maraş 92, but Dicle 2000 had the minimum content with 46.44. Maraş 92 variety, okra leaf shape cotton cultivar, for cotton seed yield was the highest with 509.93 kg da-1, Siokra ¼ had the minimum cotton seed yield (365.56). Seed yield was pozitive correlation with leaf area index, but was negative correlation with number of leaf per plant.

The purpose of this research is to determine the sex reversal of the Nile tilapia fries fed in separate times with dietary including 17-?-methyltestosterone (MT) hormone. The experiment was conducted in five groups and two replicate at 28 ºC. The fries were fed with diet containing 60mg/kg MT for 28 days from 1, 5, 10 and 20 days after yolksac absorption. At the end of this period, all groups were started to feed with control diet. The resulting sex ratio in the control group is 55% male and 45% of female. Maximum ratio of sex reversal with value of 100% was observed in the 2nd group fed with diet including MT from first day after yolksac absorption. In 3rd, 4th and 5th groups; the sex ratios were determined as 90%, 95% and 90% male; 10%, 5% and 10% intersex respectively. These results indicate that the effect of the hormone on the sex reversal is, parallely decreasing with age and weight of the tilapias fed with diet including hormone.

This study was conducted to investigate the effects of NaCl levels on germination of confectionary sunflower genotypes in 2007. Seeds of Opal, Beyaz, Suriye Nevadasi, Elazig, Kıbrıs, 01M007, 01M008, 01M012 and 01M013 were used as material. Electrical conductivity (EC) values of NaCl solutions were 5, 10 and 20 dS/m. Distilled water (0 dS/m) served as control. Germination percentage (%), mean germination time (day), root length (cm), shoot length (cm), seedling fresh and dry weight (mg) were measured at 10 days after sowing. As a result of the research, genotypes showed different response to NaCl. Increased NaCl levels resulted in both decreasing in germination and inhibiting of seedling growth but increasing in mean germination time. The least affected genotype by NaCl concentrations was Beyaz. Germination and seedling growth were inhibited at 10 dS/m and above. It was observed that NaCl depressed seedling growth of the genotypes rather than germination because five genotypes germinated but did not have root and shoot to be measured. Moreover, it was concluded that hull ratio of the seed was an effective factor for germination regardless of NaCl levels. It was evaluated that a positive and significant correlation (r=0.692**) between hull ratio and water uptake is an important clue for delaying germination.

Key Words: Confectionary sunflower, NaCl, germination, seedling growth

The term we live in known as conventional is a beginning of the conscious of possibility of risks of depletion. Such reasons like, fossil originated energy sources can be consumed before the time it is guessed, these sources can cause huge and irrevocable catastrophes, they can not be enough to the need of rising energy sources and newly developing technology and for the wish of the developed countries to rise and widen the variety of useable energy, investigators new focused on the searching for new and renewable energy resources. Today, the variety of new and renewable energy sources are increasing, some part gaining value as alternatives of economy, some part of it is still under investigation from its both economic and technical sides and almost everyday, there appears a new source of energy. The most common side of these sources are that they do not cause short or long term negative effects. Bio fuels are within the mostly new of these with this aim. The reasons that they can be used in present motor technologies without making any change, as they have a close product to diesel fuel, as it can be gained from both animal and vegetable sources and it has an environment causes investigations to go on this way. It is impossible to use vegetable oils directly to the motors as their high viscosities. So the methods are appliquéd is to solve this problems which. The objective of this research is to determine the feasibility and examine the effect of cottonseed oil methyl and ethyl esters which are produced by transesterification method and blending method used as fuel on the performance and emissions controls of diesel engine. For this purpose, a naturally aspirated, direct injection, single cylinder Lombardini LDA 450 model diesel engine was used as the power unit. The engine displacement was 0,454 L with a 85 mm bore and 80 mm stroke. The compression ratio was 17,5:1. the test engine was attached to a 40 kW hydraulic dynamometer to measure torque. During the test, torque, emissions values and fuel consumption were measured with respect to the engine speed. The brake power, brake specific fuel consumption values are also calculated. Accordingly, cottonseed oil alkyl esters were found to closely similar to those of diesel fuels.

Fritillaria persica L., which is a species produced and exported from Turkey, can be propagated both vegetative and generatively. Using generative production, it needs four to six years to reach for the required bulb size for export. Vegetative production period is shorter than the generative one. This study was carried out in the experimental fields of the University of Ankara, Faculty of Agriculture, Department of Field Crops, during 2003-2005. Bulbs of Fritillaria persica L. were used as plant materials in this study. The cutting methods used in this study was as follows: a) bulbs were not cut as control, b) basal cuttage carried out by cutting vertically from the base to center of the bulbs, c) bulbs were cut vertically from the top part to the center d) The basal cuttage was carried out by deep incision around the base, and e) the basal parts of bulbs were carved by knife conically. The experiment was established as a randomized complete block design with three replications. Bulbs were planted with 30 cm row spacing and 30 cm intra-row spacing. Plots were constituted as 3 rows with 7 bulbs each. Plant height (cm), flowering percentage (%), flower cluster length, fruit rate, number of fruits, number of harvested bulbs per planted bulb and bulb yield per decare were determined in this study. Our results suggested that different cutting methods significantly affected numbers of harvested bulbs per plant and bulb yield per decare.

This research was conducted to determine the effects of different phosphorus doses on yield and yield components of three rapeseed varieties (Westar, Marinca ve Liravell) in 2004 and 2005 years under Van ecological conditions. Field trials were arranged in a completely randomized design with three replicates at experimental fields of Agricultural Faculty of Yuzuncu Yil University. According to the results of this research, significant differences were found among rapeseed varieties and phosphorus doses with respect to plant height, pod number per plant, seed yield, protein ratio, oil ratio, and oil yield. Generally, yield and yield components increased according to increasing phosphorus doses. However, there was no significant differences between 60 kg/ha and 90 kg/ha phosphorus doses in point of seed and oil yield. According to the mean values of two years, the highest pod number per plant (81.9 ) and oil ratio (%39.5) were obtained from 60 kg P/ha application, the highest seed yield (1458 kg/ha) and oil yield (570 kg/ha) were obtained from 90 kg P/ha application. In addition, this study revealed that the highest seed (1419 kg/ha) and oil yield (548 kg/ha) was obtained from Marinca rapeseed varieties.

In this study, the effects of irrigation methods (drip, furrow and sprinkler) on soil ammonium and nitrate-nitrogen leaching were investigated in the effective root zone (0-80 cm) of maize. The study was established as a field experiment of randomized plot design and ammonium-nitrate fertilizer was applied one time with sowing of maize. During the plant growth, ammonium and nitrate-nitrogen were determined and movement, nitrification and losses of nitrogen were investigated for the soil samples taken from the root zones of 20 cm increments at different times. The results indicated that the effects of drip, furrow and sprinkler irrigation methods on ammonium and nitrate contents at root zones were not found significantly different. It was explained with an approximately same amount of water application during the irrigation of different methods. This study showed that application of whole amount of fertilizer at one time resulted in the most nitrogen losses from the root zone after first irrigation of three methods. It is suggested that application of fertilizer at different times during the plant growth when they need nitrogen at high amounts should be done to reduce the loses of nitrogen from the root zone.

Population development of Aculus schlechtendali (Nalepa) (Acarina: Eriophyidae) was investigated in three different locations (Keçiören, Beşevler and Kalaba) in Ankara, on Malus floribunda L. (Rosasacae) during 2004 - 2006 years. Two-year of observations revealed that A. schlechtendali individuals were hibernates in deutogyne stage in the crevices and hiden places of the trees. They began to move to the blossoms of the plants at the beginning of may. Deutogynes laid their eggs on the feeding place of the youngs. In general higher eriophyoid protogyne populations were observed during May and June all three locations of the study area. The data show that the deutogyne population reached its peak by the end of May and after this, the deutogyne population levels become lower whereas protogyne population showed small rate of increas around the same time but reached its peak by mid June. Deutogyne population has been seen in low population density during the summer months. During surveys on predators of Aculus schlechtendali two phytoseiids, one stigmaeid, and one tydeid mite species, and 14 Cocinellidae species were recognized as natural enemies. Beside this, taxonomic characteristics and distribution of this eriophyid species were indicated.

Our pastures and rangelands have been destroyed because of excessive and early grazing and not making attention works. Notwithstanding in amount of crossbred and import breed animals compared native breed have been nowadays important increases. Consequently, in order to meet hay requirement of our animal existence apt gradually intensive agriculture, it is necessary increase of forage crops field and yields. With decision 2000/467 numbered council of ministers of Ministry of Agriculture and Rural affairs, in supported forage crops cultivation has occurred important increase. But in these increases is not sufficient to meet requirement hay of available animal existence. Consequently, making supports to increase field and yield of forage crops cultivation have been continued increasing and diversifying. Absolutely seed problem must be solved in forage crops. Farmers must informed about forage crops cultivation and important of forage crops for animal feeding.
