Plant and Soil Aims and scope Submit manuscript

Summary

Seed treatment with cobalt nitrate followed by foliar spray, foliar spray alone, seed treatment with cobalt followed by Rhizobium inoculation, increased nodule development, and yield significantly. Nodule number and nitrogen content were positively correlated. Cobalt uptake by the plants increased with cobalt treatments. Among the treatments seed and foliar spray influenced all the plant characters most profoundly and the highest yield was obtained in this treatment. In the present study an attempt has been made to investigate the influence of cobalt in relation to growth, nodulation, nitrogen content, and yield of the groundnut crop.
