Abstract

Various methodologies (soil or foliar application) and doses of zinc (Zn), iron (Fe) and manganese (Mn) either in conjunction with urea or in combination with one another were used to evaluate grain and straw production as well as nutrient concentration and their uptake in wheat. The experiment's findings showed that adding Zn, Fe and Mn significantly enhanced grain and straw production over control as well as available nitrogen (N), phosphorus (P) and potassium (K) content and their uptake. When 2.5 mg Zn kg-1 + 5 mg Fe kg-1 + 5 mg Mn kg-1 + 30 mg N kg-1 was applied, the maximum grain yield, straw yield, P uptake in grain and straw, as well as K concentration and uptake in grain and straw were found. Highest N content both in grain and straw was observed when 0.5% FeSO4 + 3 % Urea were applied. Phosphorus content in grain was recorded highest when 0.5% MnSO4 + 0.5% Citric acid was applied whereas in straw maximum concentration of phosphorus was noticed when 0.5% ZnSO4 + 2% Urea were applied. Highest uptake of nitrogen in grain was found when 0.5% MnSO4 + 2.5% Urea were applied and in straw when 0.5% FeSO4 + 3 % Urea were applied. The experimental results also showed that micronutrient (Zn, Fe and Mn) concentration and uptake significantly increased as compared to control with micronutrient application (Zn, Fe and Mn).
