Abstract

Nutrient deficiency diagnosis and uptake limitation of nutrients at different phosphorus and zinc fertilizer application rates for DRYLAND WHEAT were studied. Experiment was set up in a completely randomized block design with 4 rates of phosphorus (0, 50, 100 and 150 kg/ha P2O5)and 4 rates of zinc (0, 10, 20 and 30 kg/ha Zn) in factorial arrangement with three replications in field of Dryland Research Institute station (Maragheh) for three years (1995-1998). Data were compared at different methods (DRIS and correlation between nutrient ratios and grain yield). The results showed that the correlation between nutrient ratios and grain yield was effective than DRIS method. Mn was most critical nutrient to increase grain yield compared to other nutrients. For the NUTRIENT BALANCE, between Mn and other nutrients, the ratios N/Mn, P/Mn, K/Mn and Fe/Mn should be less than 660, 29, 420 and 2.8 respectively. In contrast, the ratios of Mn/Zn, Mn/Cu and Mn/B should be more than 2.5, 10 and 9 respectively. It can be concluded that correlation method is best fitted to the NUTRIENT BALANCE and increased grain yield. As indicated by this method, the above mentioned ratios are required for NUTRIENT BALANCE and highest grain yield.
