Abstract

Peanut production in Indonesia is still low and there has been a decline in peanut production over the last five years. The low production of peanuts in Indonesia is caused by, among other things, varieties, spacing, fertilization, and attacks of pests and diseases. This research was conducted in the experimental garden of the Faculty of Agriculture, Muhammadiyah University of Jember, Jember, East Java, Indonesia. The research was conducted in the form of a field experiment designed in a factorial split plot. Main plot is the frequency of tillage, the main plot is 3 levels, namely: No Tillage, T1: Minimum tillage, T2: Maximum tillage and subplots is population optimization with 3 levels, namely: P1: plant population 830,000 tons/ ha, P2: plant population 714,000 tan/ha, P3: plant population 625,000 tan/ha, each treatment was repeated 3 times. The results showed that the frequency of tillage in peanut plantations had a significant effect on the physiological character of peanut plants. Minimum tillage is the best tillage treatment because it has a significant effect on leaf area index and plant leaf area. Population optimization in peanut plantations has a significant effect on the physiological character of peanut plants. Populations of 830,000 tan/ha and 714,000 tan/ha were the best plant population treatments because they had an effect on plant growth rate and leaf area. The interaction of the frequency of tillage with the peanut population has a significant effect on the physiological character of the peanut plant. The interaction between minimum tillage and peanut population of 830,000 tan/ha was the best treatment combination because it had a significant effect on plant growth rate parameters.

Abstract

Land conversion activities have reduced the availability of dry land for vegetable cultivation, therefore optimization of wetlands needs to be done. One of the potential wetlands is riparian wetlands. This study aims to determine the morphological, anatomical and physiological effects of shallow water table stress and waterloging on beans in riparian wetlands. The research was conducted from October 2017 to January 2018 in experimental ponds located in the Demang Lebar Daun Village, Palembang and at the Postgraduate Integrated Laboratory, Faculty of Agriculture, Sriwijaya University, Palembang. The study used a randomized block design (RBD) with control treatment (not soaked), M-13 (Water table at 13 cm below the soil surface), M-8 (Water table at8 cm below the soil surface), M-3 (Water table at 3 cm below the soil surface) and WL+2 (waterloging at 2 cm above ground level). Each treatment was repeated 3 times. The results showed that water table at 3 cm below the soil surface and waterloging increased proline content but decreased chlorophyll content, relative leaf expansion rate (RLER), specific leaf fresh weight (SLFW), and specific leaf water content (SLWC). Root tissue was formed one day after the treatment. Beans treatedwith water table at 3 cm below the soil surface and waterlogingwere only able to survive for 6 days. Beans are the adaptive plant to water table of more than 3 cm under the soil surface and has prospects for development in riparian wetland.
