Abstract

Two field experiments were conducted at El-Sirw Agriculture Research Station, Experimental Farm, Damietta governorate, Egypt during 2012 and 2013 summer seasons. The present investigation was designed to study the effect of gibberellic acid and potassium applications in improving salinity tolerance of three rice cultivars, namely; Giza 177, Giza 178 and Sakha 101. Data of both seasons revealed that, the three tested rice cultivars were significantly varied in their growth patterns, as well as, grain yield and its attributes. Giza 178 rice cultivar recorded the maximum values of plant height, number of tillers/m2, chlorophyll content, leaf area index, the contents of N, P, K and proline, as well as, grain yield and its attributes; viz, panicle weight and number of filled grains/panicle. However, the lowest values of the abovementioned traits were always shown with Giza 177 rice cultivar. Data, also, showed that, potassium and gibberellic acid applications could partially mitigate the harmful effects of salinity stress on growth and productivity of the three tested rice cultivars.
