摘　　要：Rice can grow in the non tidal lowland despite its limited soil fertility.One of the biofertilizers that can be used to improve fertility is azolla.This research aims to evaluate the growth of rice in non tidal lowlands using azolla to enrich the soil and different dosage of N(Nitrogen)and P(Phosphate)fertilization.A FCRD(Factorial Completely Randomized Design)was adopted consisting of 3 treatment factors,namely concentrations of N with doses of N1:46 kg/ha;N2:69 kg/ha;N3:92 kg/ha;P with P1:34 kg/ha;P2:68 kg/ha;and the application of azolla(A0:without azolla and A1:with 100 g/m2 azolla).The result showed that enriching the soil with azolla,fertilization dosage N and P,has a significant effect on plant height in the 4th WAP(Week After Planting).Furthermore,the interaction between azolla and N significantly influences panicle number,grain weight,and plant height at 2nd,4th,and 8th WAP.Conclusively,the application of azolla,N,and P fertilization supplied nutrients to rice crops in the non tidal lowland.
