Research area includes Bursa province. According to data from the year 2009, peaches with the 410 thousand ton production value, 10 thousand ton export value has an importance place in our country’s economy. Marmara Region (first place to Bursa) is leading in terms of production and export. In the research area, 30 agricultural organizations were examined and the gathered data is analyzed with the help of Cobb-Douglas production function. It was determined that, between the examined variables, the relations between fertilizer expenses and the other factors are relatively high. While fertilizer and irrigation expenses affect each other negatively, irrigation and labor expenses affect each other positively. According to this, it can be said that labor expenses takes a large place in irrigation expenses. When the marginal rate of technical substitution between production factors i...

Turkey's 40% of the production of table olives, 28% of peaches production, 80% of table black figs, 19% of strawberries production, 11% of tomato production, 15% of pepper production, 50% of pea production are carried out in Bursa. However, there are some problems in the production and marketing in province. There are some of needs about planning of agricultural production, important marketing investment and regulations of organization in Bursa. Producer organizations should be supported in order to reduce the problems. Misuse of agricultural land should not be allowed. Food businesses must be used advantages of modern technics about production and marketing. About of solving marketing problems, the state must be supported marketing infrastructure as well as marketing services. Unregistered trade in food should be avo...

Data were analyzed by multivariate statistical methods. Regarding the plant height, the genotype no. 23 recorded the highest value; however, the genotype no. 21 recorded the lowest one. The genotype no. 3 recorded the highest spike length; however, the genotype no. 21 recorded the lowest values respectively. The genotype no. 3 recorded the highest value of grain number spike-1. The genotype no. 4 recorded the highest value of 1000 kernel weight. The genotype no. 21 recorded the highest test weight; however, the genotype no. 7 recorded the lowest values respectively. Regarding the grain yield, the genotype no. 13 recorded the highest value (6723 kg ha-1); however, the genotype no. 16 recorded the lowest one (5244 kg ha-1). According to the two years results, the differences between triticale genotypes were found to be statistically sinificant in all components observed. The differences between the years were proved significant in all components. According to the results of factor analysis, triticale genotypes have similar properties significantly. Therefore, more than one major component has not been found. However, it was found one principal component (PC1) by factorial analyses. In addition, twenty-two examined cultivars were separated in two main groups by cluster analyses.

In the determination of the relationship, gross domestic product and the annual agricultural export data (1998-2017) were used. Initially, the unit root test was performed to identify long-term analysis. ADF method was used for the unit root test. In the long-term cointegration determination between the variables, Johansen cointegration analysis was performed. The presence of cointegration between the variables was determined in the cointegration test. The error correction model (VECM) was estimated based on the existence of a long-term relationship. Granger causality test was performed to determine the direction of the relationship between the variables. The causality analysis results reveal a bidirectional relationship between agricultural gross national product and agricultural exports in Turkey. The change in agricultural gross national product will also affect agricultural exports in an additional direction or the opposite. The growing importance of agriculture and supporting it in the economy will have a positive impact on the increase in national income.

Insanlarin cogu muhtemelen etik davranisin neyi vurguladigi hakkinda fikir sahibidirler – bu bir seyin iyi yapilmasi anlamindadir. Ekonomistler, gida uretim davranislarindaki uc cesidi betimleyerek, tarimsal uretimdeki etik standartlarin daima kendi odulunu getirmeyecegini belirleyen durumlarin da olasi oldugunu soylemektedirler. Tuketicilerin davranislari; arastirma, tecrube ve guven seklinde etiketlenmektedir. Saglik iddialari ve besin etiketlemesi konusu toplumun etik olarak davranan gida ureticilerinin ilgisini korumaya yonelik adimlar atilmasina gerek duyabildigi ve onlari etik davranislarinin istikrarini korumasini talep ettigi gercegini vurgulamaktadir. Etik matriksin ilk prensibi ve en onemlisi uretici ve tuketicinin refahini da belirten faydadir. Gida tuketiminde saglik tehlikelerine neden olacak gida uretim surecleri, tuketicilerin refahini azaltma potansiyeline sahiptir. Bunun en uc ve en tehlikeli bo...

However Turkish beekeeping sector has not utilized the rich natural resources sufficiently. Turkey is one of the most important honey producer countries. In Turkey, 200 000 agricultural organizations have activities in apiculture. But, only 20 000 of these organizations deal with apiculture as their main source of income. Apiculture sector in Turkey still has faced to some important problems with respect to high chemical use in the hives and marketing and export problems caused by quality of honey, mix harvest, and so on. The aim of this research is to analyze of apiaries ’ technical and economic aspects in Turkey. The total numbers of surveyed of apiaries in Bursa province of Turkey are 80 in 2008 production period. Although it has high quality honey production, Bursa province has the highest quality pollen production in Turkey. First of all, technical and econ...

Se observaron diferencias significativas entre las variedades para caracteristicas agronomicas tales como rendimiento de semillas, rendimiento biologico y ciclo del cultivo. El analisis de factores basado en los componentes principales (PC) mostro que los dos primeros factores representaron el 99,13% de la variacion total. PC1 explico el 98,69% de la varianza total y estuvo altamente correlacionado con los factores del tamano de semillas y de las vainas. PC2 puede ser considerado como el factor del ciclo del cultivo y rendimiento por planta. Los once genotipos examinados se separaron en dos grupos mediante los analisis de factores y de agrupamiento.
