The influence of varied potassium nutrition (20 and 40 ppm) at two levels of light irradiance on rice t.Orvza StJl;VQ (L) indicated that low light irradiance operative from 40 days after planting (DAP) to harvest reduced all physiological parameters studied. at-flowering and harvest stage though leaf area. specific leaf weight (SLW). chloro- phyll and sterility increased at both potassium levels. During the transition from veg- etative to the reproductive phase the 40 ppm potassium supply could panially compen- sate. the photosynthetic me (Pn). stomatal conductance (~~), soluble protein and chlo- rophyll. At harvest. ho~. the positi ve effect of K became weaker and there was no increase in dry maIler and yield but under normal light irradiance elevated K increased the total dry. mauer and yield. Thus, potassium raised the photosynthetic rate and veg- etative growth under low ifT3diance but this was not capable of promoting the filling of grains in inadequate illumination. . Not Available |
