Abstract:
The present investigation was undertaken to establish the critical limit of iron for soil and plant in wheat crop. All the doses of iron applied from 2.5 to 10 kg ha^-1 increased the dry matter yield of wheat significantly and it was recorded to be 645.74 to 841.95 g/m² as compared to control where mean dry matter yield was 556.64 g/m². The postulated critical level ranged from 5.30 to 5.59 mg kg^-1 and the critical limit was designated as 5.45 mg kg^-1 of iron in soils of Rajsamand district. The postulated critical level for wheat pant was obtained as 31.47 to 33.89 mg kg^-1 and that critical limit of iron in wheat plant could be referred as 32.68 mg kg^-1.
