Phosphorus (P) deficiency is one of the of the most important nutritional constraints to rice growth across the globe. The desire to improve the P acquisition efficiency of rice arises because of very low use efficiency of fertilizers and also are not always adequate to overcome the crop production constraints. Fertilizers are a costly input, such that their use limits the profitability of rice farming for high-input or low-input systems and the use of fertilizers for these two rice nutrients is inefficient. Rice-growing environments can be categorized into two very broad categories: ‘upland’ and ‘lowland’. For the purposes of this review, we have explored whether there are other ways by which P acquisition by rice can be emphasized. Also, recent interests in foliar nutrition in rice, we must explore some of the other no traditional ways by which external application of P have been utilized. In this brief review paper, we have also tried to review some of the genotypes which are very efficient in low P tolerance.
