Notes:
Pot experiments were conducted to study the effects of different levelsof Cobalt (Co), on the growth and on the chemical constituents of peanutplants. Co was added to soil at concentrations of 0, 25, 50, 100, 200and 400mg Co/kg soil. Dry matter accumulation, chlorophyll content,catalase activity, total proteins and free amino acids content,carbohydrates and sugars and mineral contents were determined in roots,stems and leaves of the plant. Results showed that soil polluted withhigher rates of Co depressed plant growth in terms of dry matterproduction. However, the relatively low levels of Co increased the drymatter accumulation. The results obtained indicated high accumulation ofCo in plant, although the level of Co in the soil was added inrelatively low concentrations. On the other hand, plant chemicalconstituents exhibited different responses according to plant organ andCo application rate. In addition, the interaction effect both Co and Nion the mineral content of peanuts was investigated.
