Manure derived from cow used as treatment. Each treatment repeated three times. Manure dose three ton per ha of cow applied. Two swamp rice varieties, Inpara 1 and Indragiri obtained from Indonesian Center for Rice Research at Sukamandi. These varieties cultivated under recommended technology model of Integrated CropManagement (ICM). Inorganic fertilizers applied at rate 300 kg NPK Phonska and 200 kg Urea per ha by applying half dose Urea together with full dose NPK Phonska at seven days after sowing rice, while remaining half Urea applied at 24 and 38 days after sowing. Parameters measured included soil physical and chemical properties, growth and yield component rice. Results showed average rice productivity obtained through use combination both organic and inorganic fertilizers and use recommended adaptive variety Indragiri and Inpara 1 for sub optimal land was 7.61 t per ha and 7.48 t per ha, respectively. Those produced by famers was low in which only yielded 2.6 t per ha and 2.9 t per ha rice planted through direct seeding and transplanting methods.
