Abstract

Phosphorus (P) is a finite resource and is a major limiting factor for rice yield on a large area of World’s arable land. The main objective of this study was to investigate plant and soil P interaction in P limiting conditions. A P deficient 25/75% subsoil/sand mix was determined using pots in a preliminary experiment as to be used for screening 30 rice genotypes (Oryza sativa L.).The experiment was designed using a randomized complete block design to test if shallow and deep-rooted genotypes differ in extracting P present in soil by using rock phosphate in three treatments: when rock P was absent or embedded either in a shallow 10 cm layer or distributed homogenously in soil mix. All treatments were fed with Yoshida’s nutrient solution lacking of P (YNS-P). Results indicated that P treatment x genotype interaction was significant on shoot dry weight (SDW). The addition of rock phosphate especially in shallow 10 cm layer greatly stimulated plant growth where SDW of plants grown in homogenous P and shallow P significantly outgrew those in zero P treatment. Both P treatment and genotype affected root dry weight (RDW) and root/shoot ratio significantly. Rice from the aus subgroup grown in zero P treatment accumulated significantly more SDW than indica and japonica genotypes. In zero P treatment, the genotypes Black Gora, Rayada, Kasalath, Azucena, IAC25, Dom Sufid, Aux1Wild type, FR13A and especially Sadu Cho accumulated higher SDW relative to the others.
