Abstract

In order to determine the Fe CRITICAL VALUE in soils of West Azarbaijan, East Azarbaijan, Kurdestan and Kermanshah dry land areas, this study was conducted in randomized complete block design with four treatments (0, 5, 10 and 15 kg.ha-1 from iron chelate (NaFeEDDHA)) with three replications for four years (1998-2002). Then, the crop and soil data uniformity test were completed for experimental sites. The results of the experiments were interpretated by different SOIL TESTING interpretation methods as Cate- Nelson graphical, Cate- Nelson two and three classes ANOVA models, Mitcherlich equation, plant response column order procedure and interaction chi-square methods. The results showed that Fe CRITICAL VALUE by the above mentioned methods were 5.2, 8.5, 9.5, 8.7 5.5 and 4.7 mg.kg-1 respectively. Regarding nutrients absorbtion limitation in dryland condition, and significant plant response for Fe fertilizer application of 6.5 mg Fe.kg-1 in soiL final CRITICAL VALUE by averaging of Cate-Nelson two and three classes ANOV A models and Mitshcherlich equation defined 8.9 mg.kg-1 for DRYLAND WHEAT in North West of Iran. It can be concluded that SOIL TESTING interpratation methods could affect the Fe CRITICAL VALUE. Therefore, from different SOIL TESTING interpratation mehtods, Cate-Nelson two and three classes ANOV A models, and Mitshcherlich equation can be recommended for determination of Fe CRITICAL VALUE for DRYLAND WHEAT in North West of Iran.
