Influence of Growth and Yield of Wheat by Manganese Biofortification

Wheat is one of the most important staple food in the world. So, increase the productivity of wheat, nutrient management is one of the most important factor. Asset this, field experiment carried out at micronutrient project (ICAR) farm to study the effect of soil application of Mn besides their scheduled foliar application at different concentrations with the perspective of biofortification of wheat with Mn. The field experiment was taken with ten treatment and four replication under randomized block design. The results showed that external supplementation of Mn in wheat through Foliar MnSO₄ were found effective in increasing grain, straw and root yield over their soil application MnSO_4. Soil + foliar application of Mn also provedto be significancehigher over its both individual applications. The study further indicated that enrichment of wheat grain yield with Mn was best accomplished by soil application of Mn at 20 kg MnSO₄ ha⁻¹ followed by its three foliar sprays at 0.5% caused substantial increase in its uptake by wheat. Similarly, the straw yield and root biomass higher by its soil + foliar application i.e. 20 kg MnSO₄ ha⁻¹+ three foliar spray at 0.5% of MnSO₄.
