Abstract

The results of a pot experimant to study the effect of organically complexed iron on different nutrient ratios in sorghum crop revealed that there were significant negative relationships between Ca/Fe ratios as well as P/Fe ratio and drymatter yield of 30 and 60 day old plants, grain and straw. There were significant positive relation- ships between Fe/Mn. Fe/Zn and Fe/Cu and dry matter yields of 30 and 60 day old plants, grain and straw. There was no significant relationship between K/Ca ratio and drymatter yield of 30 and 60 day old plants, grain and straw.
