Abstract
Mean yield of sorghum shoot studied in 18 aridisols was observed to increase by 19 per cent in response to the application of 10 ppm Fe over control. A response of more than 20 per cent was obtained in 54.5 per cent soils. A highly significant positive relationship was obtained between Bray's per cent yield and DTPA extractable Fe. A critical limit of 4.5 ppm DTPA extractable Fe was established to separate Fe responsive soils from non-responsive ones.Downloads
