Abstract

The rational application of fertilizers is one of the vital factors which control rice yield. The objective behind the rational application of fertilizers is to supply a reasonable amount of nutrients, synchronizing with the requirements of the crop at different stages of growth. The absence of information regarding the uptake of nutrients by rice has led to haphazard application of fertilizers regardless of the actual requirements of nutrients during different stages of growth. This has not only reduced the advantages of fertilizer application but sometimes depressed the yields also, when ferti lizers were applied without taking into consideration the actual plant needs at different stages of growth. Hence, the present investigation was planned and carried out with a view to furnish information on this aspect.
