Abstract

Bangka Island is known to have red-yellow podzolic soil type with acid characteristic and is rarely to take as agricultural land. Planting cassava in local area might be a source for local food needs diversify. The purpose of this study was to determine the productivity of the 10 genotypes cassava landrace on red-yellow podzolic soils type. The experiment conducted in the Balunijuk village, Bangka as reference. Experimental design used randomized block design with 10 genotypes Bangka cassava landrace (Upang, Sekula, Bayel, Mentega, Kuning, Batin, Pulut, Sutera, Rakit and Selangor) as treatments. The results showed that 10 genotypes cassava tested produce well on a red-yellow podzolic soils. Morphological analysis performed on tuber parts of Bangka cassava landrace showed outer skin color, skin and tuber flesh color were vary among genotypes. Sutera had the highest tuber production for 2960 g/plant. Cluster analysis based on isozyme markers divided in two groups with similarity coefficient of 0.742.

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.

Abstract

Bangka Belitung Island has alot of degraded lands due to tin mining activities. Because the people do not use those for farming, the lands will be the places for unconventional mining continuously. Based on this situation, the researcher did some extension activities and tarinings which aimed to introduce LEISA technology to the farmers in the period of June-Desember 2009 in Kace Village, Mendo Barat Subdistrict, Bangka Regency. The results indicated that 73.81% of the participants strongly agreed and nobody disagreed to the implementation of LEISA in post-tin mining land. the percentage of public confidence to the success of LEISA program in increasing the farmers’ income was about 24.39% for the confidence level >81% and 36.59% for 61-80% of the confidence level. SWOT analysis showed  that government and security officials needed to guarantee the safety and the legal certainlyof agricultural development in post-tin mining land, and also needed to be a partnership among the farmers,  institutions, relevant organizations and government to help the fulfillment of the material and means of agricultural production that can not be supplied by the people independently.
