摘要

Plant response column order procedure was used to determine critical levels of Fe, Mn, Zn, Cu and B for dryland wheat in West Azarbaijan, East Azarbaijan, Kurdestan and Kermanshah Provinces of Iran. Series of experiments were conducted in randomized complete block design with 4 treatments of each micronutrients (0, 5, 10 and 15 kg ha~(-1) Fe as iron chelate (NaFeEDDHA); 0, 5, 10 and 15 kg ha~(-1) Mn as manganese sulfate; 0, 5, 10 and 15 kg ha~(-1) Zn as zinc sulfate; 0, 2.5, 5 and 7.5 kg ha~(-1)' Cu as copper sulfate and 0, 1.5, 3 and 4.5 kg ha~(-1) B as boric acid) with three replications for four years (1998-2002). The collected data were used in plant response column order procedure and interaction chi-square (probability of no interactionbetween soil classes) models. The results for boundary of between soil deficient and sufficient classes or critical levels by plant response column order procedure and interaction chi-square model for Fe, Mn, Zn, Cu and B critical values were determinedas 4.7, 11.2, 0.7, 1.4 and 0.5 mg kg~(-1) soil, respectively; predictable values for critical levels of micronutrients were also calculated as 99.5, 94, 87, 88 and 78%, respectively. From the results, it can be concluded that soil Fe, Mn, Zn, Cu and B requirements and dryland wheat response relationships can be determined by plant response colunm order procedure and interaction chi-square methods. These methods can be applicable for classifying and prediction of soil micronutrient needs in dryland wheatcultivation in Northwest region of Iran.
