“…This process can also ensure normality and homogeneity in the distribution of the data. In addition, continuous and categorical data can be included in the model at the same time with CHAID analysis (Doğan, 2003). For this reason, CHAID analysis removes the distinction between parametric and non-parametric and has a statistically semi-parametric feature in the method algorithm (Kayri and Boysan, 2008).…”

The aim of this study was to determine the differences and the importance of the differences in terms of some socio-economic factors and agricultural practices of the producers who had soil analysis in Edirne and Tekirdağ provinces and to evaluate the opinions of the producers about soil analysis and soil analysis subsidies. Three laboratories were selected among the laboratories with the highest number of sample acceptances for soil analysis in the provinces determined in the study. For each province, total of 60 producers who applied to the laboratories in 2015 and who utilized from soil analysis subsidies, and consequently, total of 120 producers were interviewed. The analysis of the differences of the producers who had soil analysis in Edirne and Tekirdağ provinces was determined by the regression tree model (CHAID analysis). According to the CHAID analysis, in which the provinces were taken as the dependent variable, it was seen that the first most distinctive feature was the state-supported agricultural insurance. Of the producers who stated that they did not have agricultural insurance, 31% were located in Edirne and 69% were located in Tekirdağ. It was seen that 56% of the producers in Edirne and 44% of the producers in Tekirdağ had agricultural insurance. The most important feature of the second node was the education level of the producers, the third sub-node decision point was whether the producers had training on fertilization, and the fourth decision point was whether the producers faced risks in agriculture in the last three years. The four most important reasons for the producers to have soil analysis in Edirne province were to increase the product yield, to reduce the cost, to increase product quality and protect the environment, respectively. In the province of Tekirdağ, the criteria of increasing the product yield was on the first rank, increasing the product quality in the second rank, reducing the cost in the third rank and protecting the environment in the fourth rank. It is expected that it will be beneficial to introduce soil analysis conditions to the producers at the stage of purchasing fertilizers, and thus to ensure that the producer purchases fertilizer by determining the type and amount of fertilizer to be disposed of according to the analysis results.

“…In this study, CHAID (Chi-Square Automatic Interaction Detection) method was used since dependent variable of the present research is nominal categoric and independent variable is continuous categoric or nominal categoric (Doğan, 2003). CHAID analysis technique is a significant decision tree used to assess the factors influencing dependent variables and their level of significance.…”

Ever-developing agricultural technologies and progress in communication science increase competition and globalization in converge countries. Agricultural fairs offer ambient to bring producers and input-suppliers of agriculture together at certain places and times. They offer direct and efficient information about new technologies to producers. German Agricultural Society and Leader Farmer Association have jointly organized outdoor fairs in Turkey since 2010. Agriculture Days Fair is one of the most important events among these jointly organized fairs. This study was conducted to determine the reasons for producers’ participation in these fairs held in 2015 and 2017 and to determine the effects of socio-economic characteristics of the producers on their reasons for participation in these fairs. A total of 589 questionnaires were made in this study (250 in May 2015 fair and 339 in August 2017 fair). The same questionnaire forms were used in both years. CHAID analysis technique was employed in analyzing data gathered from the producers. It was observed that producers generally participated in agricultural fairs just for the excursion or spent time with their families at weekends. However, it was also determined that the producers were informed about the agricultural fairs by producer organizations and Leader Farmer Association participated in the fairs to promote a new products or to give information about new technologies and inputs. It can be suggested that beyond informing producers about the fairs, Leader Farmer Association formed within the scope of Leader Farmer Project initiated with the support of German Agricultural Society (DLG) should convey information about how important the fairs are in the acquaintance with introducing new information and technologies.

“…Her bir değişken için gruplar ikişerli olarak dikkate alınır ve eşitlik (1) kullanılarak i. değişken için elde edilen aralığın sıfır değerini içerip içermediği kontrol edilir. Eğer sıfır değeri belirlenen aralıkta yer alıyorsa, ilgili gruplar arasında anlamlı bir farklılık olmadığı, aksi durumda grupların farklı olduğu şeklinde yorumlanır [7].…”
