Barley (Hordium vulgare L. var. Jyoti) plants were raised in sand culture conditions with nil (0), 6.25, 25, 100 and 400 ppm levels of DTPA along with full nutrition solutions. Effect of DTPA on growth and tissue concentration of minerals were studied. Yield of barley plants at all the stages of growth studied showed an increase with the increase in levels of DTPA up to 25 ppm. Increase in tissue concentration of calcium, iron, manganese were found in the range of 6.25 to 25 ppm level of DTPA. However, DTPA decreased the nitrogen contents of plants.
