The effect of the application of fertilizer on the quality and quality of wheat genotypes in Varamin region

To study the effect of the application of different levels of macro and micro elements on qualitative and quantitative characteristics of the wheat genotypes (Triticum aestivum) a Split plot exferiment arranged in randomized complete block design with three replications was conducted. The research field of the Ghaleh-sin located at Varamin branch in 2006-2007.The main plot consisted of appling fertilizer at 5 levels (1-N,P 2-N,P +K 3-N,P,K +Zn 4-N,P,K,Zn+Fe5-N ,P, K, Zn+Cu)and sub plots, consisted of the 3 genotypes (Shiraz, Pishtaz, M72). Analysis of data indicated that the best results were obtained in the Shiraz genotype with 4443.2 kg/h grain yield. The effects of Application of fertilizer were significant. The highest grain yield achieved from N,P,K ,Zn, Fe , Cu with 4941.5 kg/h, the lowest grain yield and another characteristic was obtained from appling only N ,P. Analysis of variance showed a significant effect of Ratio Fitik Acid/Zn at Applying fertilizer. The lowest ratio was obtained from applying N , P , K, Zn and Fe (A4).
