Effect of Sulfur and Zinc Nutrition on Yield and Uptake by Wheat

A field trial was performed to study the effect of zinc (Zn) and sulfur (S) on yield and uptake by wheat crop at research farm, the University of Agriculture (34° 1′ 2″ N, 71° 28′ 5″ E,) Peshawar, Pakistan during 2019–2020. The experiment was laid out in a Randomized complete block design (RCBD) with factorial arrangement and was replicated three times. Four Zn levels (0, 5, 10, and 15 kg Zn ha−1) and four S levels (0, 30, 60 and 90 kg S ha−1) were used. Wheat plant biomass, grain yield and straw yield were significantly (p ≤ 0.05) affected by different levels of Zn and S. Plant biomass (8514 kg ha−1), grain yield (3887 kg ha−1) and straw yield (4531 kg ha−1) were significantly (p ≤ 0.05) greater with combine application of Zn at 15 kg ha−1 and S at 60 kg ha−1. The interaction (Zn x S) was found significant for all the above-mentioned parameters including S and Zn content in plant and post-harvest soil. It can be concluded that application of Zn at 15 kg ha−1 and S at 60 kg ha−1 has the potential to enhance wheat yield and yield components in the prevailing soil and environmental condition.
