Field experiments were conducted in rabi and kharif seasons to find out the effect of potassium application on lowland rice in marginally saline soils. The results indicated that application of 125 kg k2 O/ha in three splits at transplanting, maxmium tillering and panicle primordium initiation stages significantly increassed the plant height, number of panicless/m2, dry matter production (DMP) in both the seasons. Leaf area index (LAI) was maximum at 125 kg k20/ha in three splits during kharif season and for rabi season it was maximum under 93.75 kg k20/ha in three splits. Highest grain yield" was obtained with 125 kg k20/ha applied in three splits in both the seasons.
