Experiments under laboratory and greenhouse conditions were conducted to investigate the response of wheat to Zn application in five loess‐derived alkaline calcareous soils and to assess the contribution of Zn in various soil fractions on its uptake by plants. Zinc in soil extracted by different reagents was also determined. Total Zn ranged from 58 to 81 mg/kg. On an average 45% of total Zn in all soil fractions was associated with sand, silt and clay. Whereas silt alone held 33% of total Zn among soil fractions in the five soils. Ammonium acetate extractable and acid residual Zn (Sand, silt and clay) explained 98% of variation of Zn in plants, and 70 or 75% of Zn in the AB‐DTPA extract and DTPA extract respectively. Application of 10 mg Zn/kg soil significantly (P < 0.01) increased plant shoot dry weight, Zn concentration and total Zn content in plants over control. Concentration of Zn in plants was significantly positively correlated with Zn extracted with DTPA and AB‐DTPA in soils.
