International Journal of Soil Science1816-4978xxxx-xxxxAcademic Journals Inc.10.3923/ijss.2009.14.26T. aestivum L.) in Northwest of Iran]]>FeiziaslV.JafarzadehJ.PalaM.MosaviS.B.1200941Plant 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 interaction
between 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 determined as 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 column order procedure and interaction
chi-square methods. These methods can be applicable for classifying and
prediction of soil micronutrient needs in dryland wheat cultivation in
Northwest region of Iran.]]>Agrawal, H.P., 1992Ali Ehyaei, M. and A.A. Behbahanizadeh,1993Amer, F.M., 1995Ascher-Ellis, J.S., R.D. Graham, G.J. Hollamby, J. Paull and P.
