Abstract

A pot and a field experiment were conducted to observe the growth and yield characteristics of super high yielding rice varieties， Zhongzheyou 1 and Yongyou 9 in red paddy soils (K levels: 50 and 90 mg/kg) at various potassium fertilizer rates (KCl: 0, 75, 150 and 225 kg/hm2 )． The soil K content had significant effect on the panicle number, pencentage of productive culms, grain number per panicle, grain density, plant height, leaf chlorophyll content(SPAD value), leaf photosynthetic rate and grain yield． The order of the contributions to output for potassium fertilizer applicated at different stages was as follows: basal fertilizer >fertilizer applied 5 days after transplanting>fertilizer applied at the exsertion of the third leaf from the top, with grain yield difference from 3% to 10%. The plant height significantly increased with increasing potassium application rate, especially for Zhongzheyou 1. At the same time, the culm thickness increased, especially the basal culm internode. The grain yield of the two varieties increased by 5.6% and 8.8% with potassium application, and no significant difference was found among different potassium application levels.

Key words： potassium fertilizer; red paddy soil; yield
