Intervention effect Zinc and manganese significantly affected all measured wheat traits except protein percentage.
Intervention effect The interaction of zinc and manganese treatments significantly affected all measured wheat traits except plant height, spike length and protein percentage.
Intervention effect Wheat plant height was highest at 89 cm with 10 kg.ha-1 zinc.
Intervention effect Wheat spike length was highest at 11 cm with 10 kg.ha-1 zinc.
Intervention effect Number of spikes per square meter was highest at 403 with 10 kg.ha-1 zinc.
Intervention effect Number of seeds per spike was highest at 42 with 10 kg.ha-1 zinc.
Intervention effect Seed yield was highest at 5595 kg.ha-1 with 10 kg.ha-1 zinc.
Intervention effect Biological yield was highest at 10364 kg.ha-1 with 10 kg.ha-1 zinc.
Intervention effect Harvest index was highest at 54% with 10 kg.ha-1 zinc.
Intervention effect Protein percentage was highest at 13% with 10 kg.ha-1 zinc.
Intervention effect Different manganese levels gave a similar result.
Intervention effect Spraying 10 kg.ha-1 zinc with 4 gr.1000L-1 manganese gave the maximum seed yield, its components, harvest index and protein percentage.
Recommendation Producers can be advised to spray 10 kg.ha-1 zinc and 4 gr.1000L-1 manganese on wheat.
