Optimizing wheat growth and zinc uptake with compost and rice husk in alkaline conditions

The combination of RH with Zn exhibited the promising effects on wheat growth and yield. Moreover, the combined effect of RH and CP along with Zn expressed the highest performance in overall plant growth, increased soil organic matter, increased zinc concentrations in alkaline soil as well as in the grain of wheat. In addition, available phosphorus and potassium contents were also enhanced in zinc-deficient soil. This study provides the future directions to determine the effectual methods of Zn application for increasing the absorption and accumulation of Zn in wheat grains to address the human's demand.
