Growth, yield and nitrogen use efficiency of dry-seeded rice as influenced by nitrogen and seed rates in Bangladesh

The fertilizer N requirement of dry-seeded rice (DSR) grown with alternate wetting and drying (AWD) water management may differ from that of traditional puddled transplanted rice (PTR) grown under continuous flooding due to differences in N dynamics in the soil/water system and crop growth patterns. The effects of changing establishment method and water management on N fertilizer requirement may also vary between crops grown in the dry and rainy...
