Abstract

In Indonesia, rice is the staple food of most homes in urban and rural areas. Management of post-harvest activity has an important role on the rice seed quality at the storage period. One of the solutions to overcome seed deterioration is to perform invigoration. It can be conducted in some methods; those are osmoconditioning, hydration-dehydration, and matrioconditioning. The purpose of this study is to determine the effects and interaction of storage duration and invigoration toward seed viability and vigor of Bangka local rice accession Mayang. This study was conducted in the Laboratory of Agrotechnology, Faculty of Agriculture, Fisheries and Biology, University of Bangka Belitung form November 2012 to January 2014. Completely Randomized Design Factorial (CADF) was used as design of experiment of this study. The first factor is the storage duration (L) that consist of 3 treatment levels those are L7 = storage duration (7 months), L8 = storage duration (8 months) and L9 = storage duration (9 months), while the second factor is the invigoration treatment which consist of 4 treatment levels, those are K = controls, P = osmoconditioning using PEG 8000, H = hydration-dehydration and A = husk. The results showed that treatment of storage duration and invigoration statistically significant to the seed viability and vigor of Bangka local rice accession Mayang. However, there was no interaction between storage duration and invigoration. The best result was storage duration of 7 months for seed viability and vigor, while hydration-dehydration method was the best result on invigoration treatment.

Abstract

Tidal swamp areas in Indonesia have important role and strategic for agricultural development, especially to support national food security. It has a potency, land productivity and management technology. Tidal swamp land have a large area which potentially used as agricultural land, especially for rice. There are constraints for agriculture in tidal swamp areas, such as: (1) low soil fertility, (2) infrastructure is not optimally function, (3) low education farmer, (4) harvest index once a years, dan (5) high pest attacks. Total damages and losts effected by climate change, such as flood and drought, increase time by time. Because tidal swamp areas have different characteristic, we need information about the condition in an extreme climate change and its damages causes yield loses in tidal swamp areas. The rereach aimed to identify relatedness between climate change and crop production in tidal swamp areas, especially in South Sumatera. Climatic factor which giving effect to production, harvest area and rice productivity in South Sumatera from 2000 to 2012 is rainfall. It means that water availability will greatly effect the production, harvest area, and rice productivity. Sunlight and temperature have not a big role to increase production, harvest area and productivity, but there is increasing trend in temperature and lighting give effect to production, harvest area and rice productivity. Otherwise,  high humidity gives effect in decreasing production, harvest area and rice productivity.

Abstract

In order to fulfill food needs, we need another food resources beside rice. Cassava (Manihot esculenta L.) is one of the sources food that substitutes the rice. Beside that, utilization of ultisols as cropland can support the efforts to fulfill food needs. This study was conducted to determine the effect of giving Phosphate Solubilizing Fungi (PSF) to one variety (Malang 1) and three accesions of cassava (Sutera, Kuning, and Bayel) on planting in ultisol land. The experiment were conducted with a split plot design, where the main plot consists of PSF and non PSF, while the subplot consists of 1 variety and 3 accessions of cassava. The results showed that addition of Phosphate Solubilizing Fungi (PSF) gives good effects to some characters such as plant height, number of leaves, number of tuber, and tuber weight if compared without PSF. Furthermore, only the Kuning accesion that shows the interaction with PSF for the number of leaves character.
