Improved Molybdenum-Induced Efects on Grain Yield, Macro– micro-nutrient Uptake, and Allocation in Mo-Ineicient Winter Wheat

Abstract

The study investigated the effects of molybdenum (Mo) on grain yield, macro and micronutrient uptake, and allocation in winter wheat, particularly in Mo-deficient conditions. The 
researchers hypothesized that improved Mo application would increase grain yield and 
enhance nutrient uptake and allocation in wheat. The study was conducted in a randomized 
complete block design, using a Mo-deficient soil, with three Mo treatments and a control 
group. Results showed that Mo application significantly increased grain yield, grain weight, 
and total biomass compared to the control group. Furthermore, Mo application led to 
increased uptake of macro-nutrients, including nitrogen (N), phosphorus (P), and potassium 
(K), and enhanced allocation of these nutrients in the grains. In terms of micro-nutrient 
uptake, Mo application significantly increased Mo and zinc (Zn) uptake in both the shoot and 
grain of winter wheat. However, there were no significant changes in the uptake of iron (Fe), 
manganese (Mn), and copper (Cu) in response to Mo application. The study concludes that 
Mo application can significantly improve grain yield and enhance the uptake and allocation
of macro and micro-nutrients in winter wheat, particularly in Mo-deficient conditions. The 
findings suggest that Mo supplementation can be a cost-effective and sustainable strategy for 
improving crop productivity and nutrient quality in wheat cultivation.
