Impact of zinc levels on growth and seed yield of variety Dadu Maize-1 under the agro climatic conditions of Tandojam Sindh-Pakistan

Abstract

The use of Zinc fertilizer is an essential to make sure of maximum production and its concentration in the grain. Keeping in view the six levels of ZnSO₄ such as T₁ no application of Zn (untreated), T₂ Zn @ 7.5 (25% < recommended), T₃ Zn @ 5.0 (50% < recommended), T₄ Zn @ 10.0 (recommended), T₅ Zn @ 12.5 (25%> recommended) and T₆ Zn @ 15.0 (50%> recommended) kg ha^-1were tested on the variety Dadu Maize-1. The data depicted that all the yield contributing parameters and kernel yield were recorded at maximum level under the application of T₆ zinc @ 15.0 kg ha^-1 (50%> recommended) followed by T₅ zinc application @ 12.5 kg ha^-1 (25%> recommended). Nevertheless, the lowest values were noted regarding the yield and yield components under T₁ (no zinc application). Hence, the application of T₆ zinc @ 15.0 kg ha^-1 (50%> recommended) proved suitable zinc level for achieving optimal kernel yield of variety Dadu Maize-1.
