Abstract

A nondigestion method described earlier for K determination in plant tissue was tested for measuring K in grain samples of chickpea, pigeonpea, sorghum and pearl millet crops. The method involves shaking 0.5 g of finely ground (< 0.4 mm) seed sample with 40 ml of 0.5 N HC1 for 5 minutes at room temperature ( ? 25°C). The values of K obtained by this method with grain samples of the four crops were in close agreement (r ? 0.997) with those obtained using the conventional triacid digestion technique. These results suggest that this method may also be used for routine rapid and precise K analysis is seed materials of different crops.
