Abstract
The effort to increase food production in tidal lowland areas was conducted by applying production technology through the use of superior varieties and organic fertilizer enriched with bacteria (bio organic fertilizer). This fertilizer was a formula that had been tested in swamp lowland area and proven capable to regain land fertility through action of beneficial microbia. Some microbia which used to produce bioorganic fertilizer are Azospirillium bacterium and phosphate solvent bacterium with carrier substance of chicken manure fertilizer. The reserach objective was to determine yield capacity of two rice varieties by using inorganic fertilizer and bioorganic fertilizer at tidal lowland area. This research was done at tidal lowland area of C-flooding type. The design used in this study was Factorial Randomized Block Design with 4 treatment combinations and 6 replications for each treatment. The first factor was varieties which consisted of Inpara 6 (V1) and Inpari I (V2), whereas the second factor was fertilizer types which consisted of inorganic fertilizer (P1) and bio-organic fertilizer (P2). The results showed that yield capacity of Inpari I rice variety treated with bio-organic fertilizer + 50% of recommended NPK fertilizer could increase the production of dry unhulled rice with magnitude of 165% (1.59 kg/plot or equal to 3.98 ton/ha) at tidal lowland of C flooding type. Through the provision of biofertilizers, chicken manure enriched with Azospirillum and bacteriophosphate biofertilizers contributes to sustainability agriculture, especially in tidal wetland
Highlights
Out of 20.1 million ha tidal lowland areas in Indonesia, more than 9 million ha have potential to be developed as agricultural production areas, especially for rice cultivation (Haryono, 2013)
This research had been done at tidal lowland area of C flooding type
Based on criteria according to Soil Research Council (2005), soil used in this study can be classified as very acid soil
Summary
Out of 20.1 million ha tidal lowland areas in Indonesia, more than 9 million ha have potential to be developed as agricultural production areas, especially for rice cultivation (Haryono, 2013). The efforts that can be done to increase rice production at tidal lowland area are through technological breakthrough such as the use of superior variety and fertilizing (either inorganic or organic fertilizer)(Akmal and Yufdi, 2008). Results from the previous research showed that application of bio-organic fertilizer at dose of 300 to 400 kg.ha-1 was capable to increase rice production and reduce NPK fertilizer usage by 25% from the recommended dose on lowland swamp area (Marlina et al, 2014). Utilization of the use of organic fertilizers enriched with Azospirillum and Phosphate bacteria was expected to increase crop yields, especially Inpari 1 varieties in type C tidal wetland so as to contribute to safe and healthy sustainable agriculture by decreasing the use of inorganic fertilizer
