Response of rice peat humic acid ameliorant. saturated,. soil. culture. (SSC) within tidal. swamps

Abstract

Water management is the primary key to agricultural cultivation in the tidal swamps. Saturated soil culture (SSC) technology could decrease pyrite reduction more than conventional systems. The humic acid application will improve soil fertility by chelating Fe and Al. This study was conducted in the plastic house in Karya Bhakti Rantau Rasau Village Sub District Tanjabtim District Jambi Province, from March until June 2022. This study objective is to paddy response to the peat humic acid Saturated Soil Culture (SSC) within tidal swamps. This study used a design randomized. block complete with 2 factors and 4 replicates. The first factors. was a variety consisting. IR 64 and INPARA 4. The second factors was a peat humic acid concentration consisting of: without humic acid, 0,04 g/bucket, 0,08 g/bucket, and 0,12 g/bucket humic acid. Paddy was cultivated in the bucket with 10 kg of soil. Paddy cultivated tree plants per bucket. The research result showed that the INPARA 4 growth was better than IR 64. The lowest shoot Fe content was obtained on INPARA 4 variety with humic acid 0,12 g/bucket.
