Title: Effect of salinity on growth and yield of seven rice ( Oriza Sativa L) varieties
Authors: Drammeh, Baba
Issue Date: 10-Nov-2015
Abstract: A pot experiment was conducted at Crops Research Institute (CRI), Fumesua Kumasi, Ghana to evaluate the response of seven rice varieties (Sikamo, Gbewa Jasmine 85, Nerica L19, Tox 3377, Amankwatia, IR841 and Nerica/4) to different salt concentrations. Each pot was filled with 10kg of sterilized top-soil (of a ferric acrisol) obtained from the research field of the institute. The levels of salinity studied were: 0, 2, 4, and 6dS/m. The set up was a factorial experiment with treatments arranged in Completely Randomized Design. Each treatment was replicated four times. Ten seeds were sown per pot and seedlings were thinned to two per hill at two weeks after emergence. Saline treatments were imposed by irrigating each with water containing different concentrations of sodium chloride. The result showed that plant height and tiller production were significantly affected by soil salinity. Root biomass , however , was not affected by salinity. Rice grain yield and its components were all negatively affected by salinity. Under the conditions of this study, the rice varieties could tolerate up to salt concentration of 2dS/m.
