Abstract

A pot culture experiment has been carried out to find the extent of changes occurring in the biochemicals and nutrients of maize plants (Zea mays L.) grown under different concentrations of cobalt (50, 100, 150, 200, 250 mg kg-1 soil). The growth and yield parameters such as seedling vigour, number of cobs, number of seeds per plant; photosynthetic pigments viz., chlorophyll âaâ, chlorophyll âbâ, and total chlorophyll contents; biochemicals like total sugars (reducing and non reducing), starch, amino acids and protein content and various macro- and micronutrients are determined 90 days after sowing (DAS). All the growth parameters, pigment content, biochemicals and mineral content increase at 50 mg Co kg-1 soil when compared with the control. Further increase in the Co levels (100-200 mg kg-1 soil) has a negative effect on all the above parameters.  

Keywords: Cobalt; Growth; Zea mays; Biochemicals; Nutrients.
