Salinity is veritable issue in coastal lowlands of Niger Delta, due to salt water intrusion, and can reduce yield of lowland rice. Hybrid lowland rice cultivar (particularly FARO44; SIPI) are currently distributed and cultivated across Nigerian agroecological zones but the specific effect of salinity on these hybrid rice varieties is not well defined. This study seeks to determine the effect of sodium chloride (NaCl) on germination and seedling growth of FARO44 (SIPI). The study was a pot experiment, with 5 levels of sodium chloride (NaCl) concentrations (0, 1.0, 1.5, 3.0, and 5.0 dS cm -1 ). The seeds took about 30days to germinate in the control, as compared to other treatments. Germination was 42% in the control, 45% at 1.0 dS cm -1 and 34% at 5.0 dS cm -1 . A visual assessment for salt injury showed that the Control plants had normal growth of leaves and at 5.0 dS cm -1 NaCl, there was nearly normal growth of leaves but the tips of the leaves were whitish and rolled. Vegetative growth studies showed that the height to the first leaf in the control was 4.45m and the longest height to the first leave was recorded at 1.5 dS cm -1 NaCl. The tallest (38.7 cm) plants were observed at the 1.5 dS cm -1 NaCl treatment but it was statistically similar with other treatment expect in the control which had the lowest plant height (23.4 cm). The highest number of leaves was recorded at 1.5 dS cm -1 NaCl concentration, while lowest was recorded with 5.0 dS cm -1 NaCl. FARO44(SIPI) appears to tolerate NaCl of up to 1.5 dS cm -1 .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
