The use of the seaweed extract increased significantly N, P and K uptake by grains at higher concentrations (7.5% and above) and reached maximum at 12.5%, 15% and 15% application rate respectively of the seaweed extract compared with control.Sulphur uptake by grains was significantly increased at 10% and above levels of seaweed extract applications. Nitrogen and S uptake by straw were not significantly influenced by seaweed extract applications whereas, P and K affected significantly. Highest P uptake by straw was observed at 7.5% and followed by 10% concentrations of the seaweed extract.
