| Abstract: | Summary Dicalcium phosphate dihydrate and potassium dihydrogen phosphate were applied to calcareous soil in combination with zinc
sulphate in the molar ratio of 100∶0, 100∶1, 100∶2 and 100∶4. Increasing addition of zinc sulphate into P sources gradually
increased KCl (0.01M) soluble P and Zn, NaHCO3 (0.5M, pH 8.5) extractable P and DTPA extractable Zn from soil and grain and straw yields of green gram. |
