    Abstract


    The objective of this study was to evaluate the effects of transplanting density and fertilizer doses for inbred rice cultivar ĐH12 yield. The experiments were designed by using the two factors (Split-plot type) with four transplanting density levels and four fertilizer doses. These experiments were conducted in three northern provinces in the spring and summer seasons. For the Red River Delta, ĐH12 has shown that the optimal transplanting was at 40 plants/m2both spring and summer season, chemical manure 100kg N + 100kg P2O5+ 75kg K2O/ha (spring season) and 90kg N + 90kg P2O5+ 68kg K2O/ha (summer season). For the mountainous north areas, it should be at 40 plants/m2both spring and summer seasons, chemical manure 120kg N + 120kg P2O5+ 90kg K2O/ha (spring season) and 90kg N + 90kg P2O5+ 68kg K2O/ha (summer season). Similarly, in Northern Central area, ĐH12 would be 40 plants/m2in the spring season and 45 hills/m2in the autumn season, chemical manure 120kg N + 100kg N + 100kg P2O5+ 75kg K2O/ha (spring season) and 90kg N + 9Okg P2O5+ 68kg K2O/ha (autumn season).
