Field and pot experiments were conducted for the split application of potash in paddy
(Oryza satiνa L. cultiνar Jinheung.) Production and the experimentaI resuIts were analysed
with regard to the yield of paddy and its yield components. The absence of potash at the
reproductive stages such as primodial and heading period but supplied most of the potash
at the early growth stages. resulted in an increase of panicles but in a decrease of grain
numbers per panicle and yield of paddy. On the other hand. however. the reduced amount of
potash application at the earIystage of growth showed a decreased number of panicles and
yield of paddy. paticulary where lime and fresh rice straw were applíed.
