An experiment in Petri dishes with filter paper beds using saline solutions of different electrical conductivities (ECe) 3 obtained by dissolving common salt in distilled water to study their influence on rice seed germination, and a soil culture experiment with different levels of induced salinity under greenhouse conditions to study the effect of salinity on vegetative growth and grain yield of rice, were carried out. ‘Dular,’ a local variety of rice, was used as the experimental material. Rice seeds could germinate normally in medium of ECe up to 4.5 mmho/cm. Seed germination, which began to be adversely affected from ECe of 8.9 mmoh/cm onwards, could, however, be initiated to some extent by transferring the treated seeds to distilled water. Grain yield and vegetative growth were markedly hampered at ECe of 7.2 and 9.8 mmho/cm, respectively.
