Abstract

The research objective is to increase rice productivity using a ratoon system through N fertilizer and growth regulator treatments at two flooding types of tidal swampland. It was conducted from February to August 2020. The experiment design used in this research is Split Plot Design with three replications. The main plot is N fertilizer and rice variety (NV) which consisted of N1V1= N fertilizing, 1/3 dose during planting + 1/3 dose at primordia phase + 1/3 dosis at harvest for Inpari 30 variety; N1V2= N fertilizing, 1/3 dose during planting + 1/3 dose at primordia phase + 1/3 dose at harvest for Hipa 5 Ceva variety; N2V1= N fertilizing, 1/3 dose during planting + 1/3 dose at primordia phase + 1/6 dose at harvest +1/6 dose at 21 days after harvest for Inpari 30 variety; N2V2= N fertilizing, 1/3 dose during planting + 1/3 dose at primordia phase + 1/6 dose at harvest +1/6 dose at 21 days after harvest for Hipa 5 Ceva variety. The subplot is the application of growth regulator GA3 (G) consisting of G0 = without application of GA3; G1 = application of GA3 once in 7 days; G2 = application of GA3 once in 14 days. The research results showed that N fertilizing, 1/3 dose during planting + 1/3 dose at primordia phase + 1/3 dosis at harvest and application of growth regulator GA3 60 ppm with interval of once in 7 days to ratoon rice is capable to increase rice productivity using ratoon rice system at B and C flooding types at tidal swampland.How to Cite: Gribaldi, Nurlaili, Novriani, S.
