BR3 rice was grown at the Bangladesh Agricultural University Farm, Mymensingh, May-Oct 1982 with four treatments of ZnO (0, 2, 5, and 8 kg Zn/ha) and gypsum (0, 20, 30, and 40 kg S/ha). Normal cultural operations were done. The experiment was in randomized block design with four replications. Seedlings (23 d old) were transplanted 22 May at 15 25- x 15-cm spacing and harvested at 134 d. Rough grain and straw yields were recorded. Samples of rough grain and straw were analyzed for protein content by the improved Kjeldahl method (Nx 6.25). There was a significant positive correlation between grain protein content and yield (r=0.84** ) and straw protein content and yield (r=0.79** )
