Abstract
Prospect of Swampland Development as a Source of Rice Production in South Kalimantan. The role of tidal land and lowland swamps for agricultural development especially for the production of food crops as well as supporting the state of the national food security will be increasingly important when it was associated with the depletion of the fertile lands. Some of the constraints faced in the utilization of swamp land, were not only those related with the land biophysical but also those related with the socio-economic, institutional, and infrastructure issues. It was expected at when these above-mentioned problems can be handled, the vamp land would have a great potential as a source of rice production in the country. The increase of rice production in South Kalimantan might be done through: (1) extension, increase more planting area. (2) increase the planting intensity, and (3) increase crop productivity. The improvement of rice planting areas in the swamp land in South stan is still possible, as the total of tidal and swampy area available were 183,540 and 205,545 ha, respectively. Among them, a total of 38,780 and 90.1078 ha of tidal and swampy area, respectively, were ready to utilize for growing rice. The swampland was also possible to be planted twice a year with adaptive rice variety Results of experiment in South Kalimantan indicated that by growing the right variety of rice, its production could reach up to 4.0 and 50 that in tidal and swampy areas, respectively Kalimantan

Beberapa kendala yang dihadapi dalam pengembangan pertanian di lahan rawa, bukan saja masalah biobisik lahan, tetapi juga masalah sosial ekonomi, kelembagen, dan infastruktur yang belum memadai. Apabila kendala kendala bofisk lahan dapat dikendalikan, diharapkan lahan rawa mempunyai potensi besar sebagai sumber produksi padi. Strategi peningkatan produksi padi di Kalimantan Selatan dapat dilakukan dengan (1) peningkatan luas arcal tanam, (2) peningkatan intensitas tanam, dan (3) peningkatan produktivitas. Peningkatan luas areal tanam padi di lahan rawa Kalimantan Selatan masih memungkinkan, dengan pertimbangan masih tersedia lahan pasang surut seluas 38.780 ha dan lebak seluas 90.078 ha yang dapat dimanfaatkan untuk pengembangan tanaman padi. Peningkatan produksi padi di lahan rawa dapat juga dilakukan dengan meningkatkan intensitas tanam, melalui penanaman lahan rawa dua kali setahun, yang sampai saat ini baru terlaksana sekitar 5%. Peningkatan produktivitas padi di lahan rawa dapat dilakukan dengan pendekatan pengelolaan tanaman dan sumberdaya lahan secara terpadu yang meliputi perbaikan kualitas lahan dan penggunaan varietas yang adaptif. Hasil penelitian di lahan rawa Kalimantan Selatan menunjukkan dengan varietas padi yang tepat di lahan pasang surut produktivitas padi dapat mencapai 4.0 tha dan di lahan lebak dapat mencapai hasil >50 t/ha
