      Abstract

      The research objective of this study is to carry out land evaluation for paddy cultivation in reclaimed tidal lowland area of Della Saleh South Sumatra Indonesia. Research sampling was conducted based on the land typology: of land area, ie. typology of A. B. C and D. The works were divided into two steps. field survey activities and laboratory work. The results showed thai i.e. the land has the potency and suitability for paddy cultivation which can be divided into four main groups. i.e. high potency class of (S1 and S2), middle potency (classes of S2 and 53), low potency (class of S3) and less potency (class of N). The high potency classes S1 and S2 was a land suitability for paddy cultivation with. suitability >75% and limited suitable < 25%. An acreage of this high potency land is around 17,982.3 ha (67.4% of the total research area) with its land productivity of more than> 6.0 tons dried paddy per ha per year. The middle potency classes of 52 and S3 were a land with suitability between 25-50% and limited suitable 50-751)/0. An acreage of Ihis middle potency land is around 5.389.4 ha (20.2% of the total research area) with its laud productivity of around 2-5 ton, OilS dried paddy per b.c per year. The low potency classes S3 was land suitability for paddy cultivation with limited suitable 50,· 75% and not suitable 25-50%. An acreage of this low potency land is around 3,308.3113 (12.4% of tobe total research area) with its land productivity of around 1-2 tons dried paddy per ha per year. The less potency classes of]\.l were land suitability for paddy cultivation with limited suitable < 15% and not suitable> 75%..A.n acreage of this low potency land is not found in the field (0% of the total research area) with its land productivity of around < 1 ton dried paddy per ha p~r year. The needed efforts to improve land capability from original suitability to potential land sustainability [or rice cultivation are i,e. (i) to develop drainage systems,(2) to develop water barriers to retain the waler itl the cultivated land, (3) to apply agricultural lime in tbe land, (4) to apply som , organic matters in tbe land without removal in organic mailers, (5) to remove cations ofNa and H. and (6) to apply the fertilizer of N, P and K
