The effect of mixed cultivation with green manure crops and liquid pig manure on rice growth was investigated. Field experiment in site 1 (Astragalus sinicus L.) and site 2 (Lolium multiflorum Lam.) were designed with control (non-green manure crop), PLM 100 (non-green manure crop + liquid pig manure 100%), A(L)PLM 0 (green manure crop + PLM 0%), A(L)PLM 50 (green manure crop + PLM 50%), A(L)PLM 75 (green manure crop + PLM 75%), and A(L)PLM 100 (green manure crop + PLM 100%). The results of 1,000 grain in rice plant were in the order of APLM 100 greater-than or equal to APLM 75 ≒ PLM 100 ≒ APLM 0 ≒ APLM 50 ≒ control for site 1 and LPLM 100 greater-than or equal to LPLM 75 = LPLM 50 = PLM 100 greater-than or equal to LPLM 0 ≒ control for site 2. The yields of rice in site 1 and site 2 were 636 kg 10a-¹ (increasing yield 10%) for APLM 100 and 775 kg 10a-¹ (increasing yield 12%) for LPLM 100, respectively.
