| Abstract: | Summary A field experiment was conducted at Agricultural Research Institute, Dholi during Rabi 1976–77 in sandy loam soil to study the interaction between zinc and potash in wheat. Zinc and potash were applied to the soil in the form of ZnSO4 and KCl respectively. Interaction between zinc and potash was found significant. Both the levels of zinc sulphate 12.5 kg/ha and 25 kg/ha being at par produced significantly higher grain yield over control. There was significant increase in grain yield with application of 40 kg and 80 K2O/ha over control. Potash at the rate of 120 kg in combination with 25 kg Zinc sulphate/ha decreased the yield. |
