A field experiment was conducted at the CSRC, Karamana during summer 1987 to study the effect of potassium and kinetin on carbohydrate partitioning in rice. It was found that both potassium as well as kinetin application decreased the carbohydrate concentration in the source (leaf, sheath and culm) and enhanced their accumulation in the economic sink. Their interaction effect was also favourable to mobilize carbohydrates to the grains. A dose of 35 kg K2O/ha plus a single spray of 10 ppm kinetin at 10 days after flowing (DAF) was optimum for carbohydrate yield from panicle as well as for grain yield.
