The aim of this study was to determine the genotype-environment (GE) interaction and also to determine stable corn cultivar for grain yield in Turkey. The study was carried out from 2 years and 3 different locations around the Central and South Anatolia Region. GE interaction was analyzed by linear regression techniques. Stability was estimated by the Eberhart and Russell methods. According to the stability analysis, it’s seen that the cultivar 3 was the most stable for grain yielding. Among the cultivars, the highest grain yield was obtained from cultivar 3 (9.4 t ha -1 ) at across environments. This genotype had regression coefficient ( i b =1) around unity and deviations from regression values ( ij δ =0) around zero; considering that they are responsive to environment changes and they can be
This study was conducted at the Experimental Field of the Bahri Dagdas International Agricultural Research Institute, in Center of Konya, Turkey, between the years 2003-2004 in order to determine the effects of various nitrogen doses on yield and chemical composition of soybean cultivars. Athow and Defiancy cultivars of soybean were used in this study. 0.0, 2.5, 5.0, 7.5 and 10.0 kg/da nitrogen doses were applied while sowing. The results from both years were evaluated together. According to the results of the research; application of various nitrogen doses on two soybean cultivars resulted in significant differences in seed yield and chemical composition. Oil content decreased with added nitrogen fertilizer. The greatest values of seed yield and chemical composition were generally obtained at a dose of 7.5 kg/da nitrogen. Higher nitrogen doses led to lower values of seed yield and chemical composition. Defiancy cultivar had generally higher seed yield values in all traits and lower starch contents than Athow.
Knowing the quality and content of the irrigation water used in agriculture irrigation management is very important in terms of the impact on soil-plant and the environment. All surface and underground water used in irrigation also contain salts dissolved in their plant bodies. Salts transmitted to the soil by irrigation water, affect the physical and chemical properties of the soil and as a result, they decrease in yield and quality. This study was carried out to investigate the salt contents of irrigation water in irrigated agricultural areas in Kirsehir province in the Middle Kizilirmak region and to determine the relationship between the amount of salinity in irrigation water and the distribution of plant. In the study, 120 irrigation water samples were taken from 40 different irrigation points, and the analysis of the mentioned samples was carried out at Chemistry Laboratory of Ahi Evran University Mucur Vocational High School. As a result, it has been observed that related to the contents of the water and the plants grown. The amount of salinity varied from 201 μS/cm to 1878 μS/cm. Grain plants such as barley, wheat and triticale are at the foreground in areas where salinity is high, while plants such as walnut, grape, bean and lentil are grown in places where salinity is low. In the studied areas, very high salinity was observed in 23 areas, while low salt concentration in 38 areas was observed. The remaining 59 regions were found to have moderate salinity.
This study aimed to determine the outlier values in live-weight performance data of Japanese quails. Japanese quails were grown under the same conditions, and, after being divided according to gender, the live weight data of quails up to 56 days of age (7 weeks) was collected. For both male and females, measurements on 50 animals were done, and these values were measured over. For each week measurement, values were separately determined. In order to determine the outlier values in each measurement, DFBETA and DFBETAS criteria were used. In males, females, and in all the flock a high number of outlier values was found. However, more outliers were observed especially in females. Under the same conditions, in spite of the training, the potential environmental effects of the variability in females was originated to react more quickly than in males.
Leaf area is related to many physiological and agronomic studies including growth, photosynthesis, transpiration, and energy balance . The study aimed to determine the leaf area estimation of sugar beet ( Beta vulgaris L.) at different nitrogen levels under field conditions. The study was conducted out in split plots in randomized complete blocks with three replications in 2012-2013, and measurements were taken from leaf parameters, such as length (L) and width (W), petiole length, and the total number of leaf per a sugar beet. The artificial neural networks and such non-linear methods as the Logistic, Richards, and Gompertz were compared to estimate the leaf area measurements. As a result, all models have shown the highest identification success in the level of third fertilization. While the ANN model in the first three fertilizer doses showed a higher definition of success compared to other models, the Richards model in the fourth fertilizer dose has been more successful. An increase in the nitrogen level has accelerated the plant growth. While the ANN model remained insufficient for very rapid growth identification, the Richards model is defined in more successful rapid growth

Groundwater is a significant water resource widely used for drinking, irrigation, and industrial purposes. Therefore, the determination and evaluation of quality parameters are of great importance for the sustainable use of groundwater resources. This study was conducted to evaluate the irrigation water quality of groundwater wells in the Seyfe Lake Basin and to determine the variation in groundwater quality parameters. Water samples were taken from six groundwater wells during pre-irrigation (June) and post-irrigation (September) periods of the years 2008-2009. Some physicochemical parameters were determined, such as: EC, pH, Na + , K + , Ca +2 , Mg +2 , Cl - , ,, HNO 3 , NH 3 , total salt content, and water hardness. The parameters of sodium adsorption ratio, residual sodium carbonate, and sodium percentage were computed to evaluate water quality. For statistical analysis of the data, the repeated measurements method was employed. Water samples were evaluated according to the criteria of the Water Pollution Control Regulation and the researchers determined that based on the electrical conductivity, total amount of salt, percent sodium, sodium, chloride, and nitrate values of the groundwater well, it cannot be used for irrigation water due to higher than the permissible values of the usable water.
The animal material of the study consisted of quails of similar live weight selected from a randomly mated 14-week-old flock. Selected 29 male and 29 female quails were placed in individual cages with a ratio of 1-1 male females. The chicks obtained from this flock were fed ad libitum with 24% crude protein and 2900 kcal/kg metabolic energy from hatching to the sixth week of the experiment. The sexes of those who completed their development up to three weeks in growth cages by marking were determined and placed in special cages one by one according to their genders. In the study, 86 quails belonging to each family, including 3 siblings, were used. At the end of the trial, the survivability decreased to 75.58%. When considered as the sum of Male+Female, it is seen that the average of the starting weight is 8.776 g, the final weight measurement is 176.16 g and the average weight is 86.47 g. While this average weight is 85.06 g in females, it increases to 87.43 in males. Considering the average heritability, it was clearly separated from the others with a heritability value of 0.586 and this was found to be statistically significant (P
Abstract This study was conducted to determine the opinions of the farmers producing dry bean landraces (DBL) at the regional level of Turkey (eight provinces). In total, 140 questionnaire forms were filled by DBL producers. The population and then the sample size were determined according to 2016-year-preliminary-study. The capital structures of the farms according to the production types were evaluated using the Five-Capital-Model approach, and differences were tested by parametric and non-parametric statistical methods. The study showed that 37.86% of the DBL producers produce as the home-garden-type while 62.14% of them as the field-type, which is larger than 0.1 ha. While home-garden-type producers majorly produce for their own family needs, commercial ideas and concerns are at the forefront for field-type producers. While field-type producers have higher values in terms of five capitals, home-garden-type producers move within a more traditional way of production. More than half of the producers indicate that they will continue to produce DBL; this ratio is higher in home-garden-type producers. This indication of approximately 25% of both types of producers wherein their children will continue to produce DBL, there is a need for more human labour, efficiency and profitability concerns, production mostly by the elderly population increasing the risk of future depletion in DBL-genetic resources. This calls for more efforts to increase the awareness among the young population on the importance and protection of genetic resources and to make special policies for the protection of genetic resources by policy makers and develop models based on genetic resources.
The aim of this study is to investigate the behaviors of and monitor the changes on behaviors of Japanese quails reared in different stocking density, through using different objects, (small red balls, bunch of rope, mirrors and beads) providing environmental enrichment (EE) in the cages of quails. Six hundred of 1 day old Japanese quail chicks (mixed sex) were used in this study. Birds were reared in battery cages with four floors, each of which has two separations. The quails were placed in cage dimension in the quantities of 10 quails (lower density: LD) and of 20 quails (higher density: HD) per separation. Our hypothesis was that EE would improve the welfare of quails. The birds were observed in their cages naturally in accordance with one-zero sampling, and home cage avoidance test was performed for these birds. While the applications have significant effect on feeding and relaxation behaviors (P<0.05 levels) in LD environment, the effect of comfort, social and other behaviors was realized at P<0.01 levels in the same environment. However in HD environment, only rest behavior was affected significantly in P<0.05 level, the other properties were affected in P<0.01 levels. The live weights weren’t affected from EE (for LD, P=0.134 and for HD P=0.216). It was determined in the result of this study that the objects hung in the quail cages had potential effect to improve the welfare of quails.
