Abstract :The aim of this study was to determine the effect of increasing levels of iron applications (0-6-30-60 ppm) on dry matter weight, active (Fe+2 ) and total iron and iron uptake from soil and chlorophyll contents of different bean varieties under green-house conditions. According to the results in the varieties of Göynük-98 and Şehirali-90 with the increasing iron applications (except 6 ppm Fe) generally dry weight decreased. With the comparing of iron doses, 6 ppm iron was found to be the most suitable dose in view of dry weight. Variance analysis showed that the difference among genotypes, iron application rates and ‘genotype x iron’ interactions in dry matter weight, total and active iron content and iron uptake from the soil were found statistically significant (p< 0.01). In the result of analysis correlation it was between dry weight and active iron content determined that statistically significant (p< 0.01) negative correlation. The relationships between dry weight and chlorophyll a content (r = - 0.229**) and chlorophyll a+b content (r = - 0.221**) were statistically significant (p< 0.01). But the relation with chlorophyll b content (r = - 0.226*) was statistically significant at the level of P<0.05. It was found that statistically significant (p< 0.01) positive correla-tion between active iron and total iron contents (r = 0.935**) , and again between active iron and iron uptake from the soil (r = 0.900**).Keywords : Fasulye, klorofil miktarı, aktif demir, toplam demir
