The effects of compound fertilizer，slow/controlled release fertilizer，organic-inorganic mixed fertilizer and no nitrogen fertilizer on the growth dynamics and yield of rice under the conventional mid-season rice and the rice-shrimp symbiosis were explored to provide a theoretical basis for optimizing nitrogen management and improve yield under different rice farming models.The split zone design was adopted，with 2 rice cultivation patterns as the main zone and 4 nitrogen fertilizer types as the split zone.The rice leaf area index (LAI)，photosynthetic potential (LAD)，dry matter accumulation (DW)，growth rate，photosynthetic characteristics were investigated during the main growth period of rice，and the yield and yield component factors were determined at maturity，and the harvest index and nitrogen partial productivity were calculated.The results showed that the total growth period was prolonged under the rice-shrimp symbiosis.LAI at heading stage，DW at heading and maturity stages，growth rate，SPAD at heading，net photosynthetic rate and yield were significantly reduced，LAD from heading to maturity stage increased significantly.The reproductive growth period and total growth period of no nitrogen treatment under the conventional mid-season rice were shorter than those of other treatments，and the vegetative growth period and total growth period of no nitrogen treatment under the rice-shrimp symbiosis were longer than those of other treatments.The organic-inorganic mixed fertilizer had the highest LAI，LAD，photosynthetic capacity at heading stage and 1000-grain weight.The photosynthetic capacity at the tillering stage and growth rate from the heading stage to the maturity stage of the treatment of compound fertilizer were the highest.Slow/controlled release fertilizer had the DW，growth rate from tillering stage to heading stage，effective panicles number，yield and partial productivity of nitrogen fertilizer were the highest for the treatment of slow/controlled release fertilizer.Slow/controlled release fertilizer was the best nitrogen fertilizer with the highest rice yield and nitrogen partial productivity under the two rice farming modes.
