| dc.description.abstract | The study was conducted with the general objective of evaluating the effects of different concentrations of PBZ on the growth, water use and grain yield of two special quality rice varieties (NSIC Rc216 and Dinorado) under drought stress condition. The results showed that PBZ generally improved tiller and panicle number which is supported by correlation analysis with moderate and strong relationships, respectively, Among root parameters evaluated, only lateral roots showed positive moderate relationship with PBZ indicating PBZ has the potential of improving this root parameter which is considered as key root trait under drought condition. Moreover, tiller number and root parameters showed weak to very weak relationships to grain yield and water use. Thus, the targeted parameters of traits (tiller number and root parameters) did not contribute to better performance of NSIC Rc 216 and Dinorado under contrasting water regimes. Lastly, PBZ showed different effets on grain yield two rice ecotypes wherein positive effects for newly released modern society (NSIC Rc216) but negative effect on traditional variety (Dinorado). This indicates that different rice varieties require different levels of PBZ; thus, it is recommended to conduct another study using different traditional and modern rice varieties under field condition. | |
