Two field experiments were conducted with Co-51 variety at Annamalai University in randomised block design comprising ten treatments to determine the effect of foliar application of liquid inorganic and organic fertilizers alone and in combination with 75 % recommended NPK on growth and yield of rice. The results revealed that application of 75 % NPK with alternate spraying of liquid fertilizers – SPIC NPK and Isabion on 10, 20, 30, 40, and 50 DAT increased the plant height (2.3,8.1 cm), LAI (1.3,1.9), number of tillers /hill (8.3) and grain yield (530 Kg/ha) compared to 75 % recommended NPK application alone. The same treatment increased the grain yield up to 141 Kg/ha over 100 % recommended NPK.
