The Role of Potassium in Improving Growth Indices and Increasing Amount of Grain Nutrient Elements of Wheat Cultivars
M.A. Bahmanyar and G.A. Ranjbar

Abstract:
In order to consider potassium role in improvement of growth indices and increasing the amount of nutrient elements in wheat grain, a pot experiment has been undertaken in 2005. In this experiment cultivars Tajan and Nye 60 have been used in four levels of potassium (0, 100, 200 and 300 kg K2O ha-1 from source of K2SO4) in form of factorial experiment based on a completely randomized design. Results showed that application of potassium increased dry matter, 1000 grain weight, tiller number, seed and leaf potassium content, seed Zn content, plant height, seed Iron and protein content. Also, grain yield, 1000 grain weight, seed potassium and Zn content in cultivar Nye 60 were higher than in cultivar Tajan and tiller number and seed protein content in cultivar Tajan were higher than in cultivar Nye 60.
