Abstract
Agronomic constrains of vegetable cultivation in riparian wetland are low soil quality and possibility of shallow water table and submergence during reproductive stage. These constrains can be overcome by amelioration and cultivation of adaptive crops. The main objective of this dissertation was to obtain adoptive technology and economically affordable for improving soil quality and to select adaptive vegetable as a recommendation for peasants to improve riparian wetland productivity. This research was conducted in Macan Kumbang Demang Lehar Daun Palembang, Integrated laboratory of graduate school Universitas Sriwijaya, Jakabaring and Pemulutan Ulu village, Ogan Ilir District, South Sumatra. Grounded research was conducted prior to this research in order to explore the common vegetable cultivated by local peasants. M-8 (water table at 8 cm below soil surface), M-3 (water table at 3 cm below soil surface) and WL+2 (waterlogging; 2 cm above soil surface). Based on the pt and 2 experiment, the water table on the 3rd experiment was managed at 10 cm below soil surface (M-10), 5 cm below soil surface (M-5) and control. The purpose of this treatment was to observed the proper water table for optimum plant growths in shallow water table condition. Results showed that eggplant, snap bean and tomato were tolerant to water table at more than 3 cm below soil surface. Eggplant showed the highest tolerance ability in shallow water table especially in waterlogging condition as it was able to survive and grow during recovery period. Based on the tolerance ability, eggplant>snap bean> tomato. In order to understand deeply about crop adaptation ability, beside growth aspect, physiological aspect was observed in 2nd research. Plant physiological responses were observed through proline leaf content analysis carried out in the graduate laboratory of Sriwijaya University. Proline content in leaf is a main indicator for crop adaptation under environmental stress. Based on the l st research, eggplant and snap bean were selected. Shallow water table treatments were M-13, M-8, M-3 and WL+2. This research revealed that up to 6th day leaf proline content of eggplant as well as snap bean increased, however in waterlogging condition snap bean proline content was 43,23% higher than eggplant, meanwhile in 3 cm below soil surface treatment, snap bean proline content was 85,02% higher than eggplant. Data indicated that snap bean was more stressed than eggplant. Another fact found that increment of proline contents in
