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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
