Abstract

Expansion of new paddy land for rice in the tidal area is still experiencing problems, especially their toxic concentrations of Fe which can affect soil productivity. Efforts to improve the productivity of the newly opened paddy fields of tidal swampland are with drainage and specific nutrient management. The purpose of this research is an effort to increase the productivity of land through drainage management and application of ameliorant against iron toxicity in rice at the newly opened tidal swampland. The experimental design used was a Randomized Block Design is repeated 5 times.  The results  showed  that  technology  of  1 week drying and 1 week inundation, limed 2 t ha-1 and fertilized N 112.5 kg ha-1, P2O5 22.5 kg ha-1, K2O 67.5 kg ha-1 and organic materials by 5 t ha-1, can increase rice yields by 237% from 1.40 t ha-1 to 4.72 t ha-1 of dry milled grain and can reduce 50% of Fe in the soil content of 384 ppm to 192 ppm in the newly opened paddy fields of tidal swampland in dry season. While the rainy season, technology of 1 week drying and 2 week inundation, limed 2 t ha-1 and fertilized of N 86.25 kg ha-1, P2O5 30 kg ha-1, K2O 15 kg ha-1, and organic materials by 5 t ha-1, can increase rice yield 272 % from 1.21 t ha-1 to 4.50 t ha-1 of dry milled grain and can reduce 51.88% of Fe in the soil content of 1,168 ppm to 769 ppm.

Abstract

ABSTRACT Shallot cultivation in peat land was constrained by the high production costs, especially fertilizer and lime costs (Abdullah, 2011). Therefore, improvement of shallot productivity in peat land was to use local resources so that the production costs would be reduced. Potential material to be used for that purpose was sea mud which abundantly available in West Kalimantan. The productivity of several shallot varieties in peat land had not reached their production potential. The research used Randomized Block Design (RBD) with the treatment of sea mud consisted of without the treatment of sea mud (L0) and with the treatment of sea mud (L1) and several shallot varieties such as Bima Variety (V1), Manjung Variety (V2) and Sumenep Variety (V3). The research result showed that the treatment of sea mud and varieties of shallot differed significantly in improving the growth and production of shallot. Bima, Manjung and Sumenep each produced 14.73 ton/ha, 12.84 ton/ha and 9.22 ton/ha respectively. Based on profit value and B/C ratio value, the utilization of sea mud in peat land was economically feasible to be applied by farmers in West Kalimantan.
