<em>Sweet potato is an important staple food crop especially for the local people of Central Highlands Jayawijaya. There are many accessions that have always been maintained its existence to enrich their various uses. Traditionally, sweet potato accessions were grouped based on the utilization, such as for animal feed, cultural ceremonies, consumption for adults, as well as for infants and children. This study was aimed to analyze the nutritional value of sweet potatoes consumed by infants and children of the Dani tribe. Chemical analyses were conducted at the Laboratory of Post-Harvest Research and Development Center, Cimanggu, Bogor. The results showed that each of 4 (four) sweet potato accessions which were consumed by infants and children had good nutrient levels. Accession Sabe showed the highest water content (72.56%), vitamin C (72.71 mg/100 g), Fe (11.85 mg/100 g), and K levels (130.41 mg / 100 grams). The highest levels of protein (1.44%), fat (1.00%), energy (154.43 kkal/100 gram), carbohydrate (35.47%), starch (30.26%), reducing sugar (3.44%), riboflavin (0.18 mg/100 g), and vitamin A (574.40 grams IU/100 were produced by accession Manis. On the other hand, accession Saborok produced the highest value for ash content (1.32%), vitamin E (28.30 mg/100 g), and ?-carotene (64.69 ppm). The highest level of crude fiber (1.81 %) and thiamin (0.36 mg/100 g) was produced by accession Yuaiken.</em>

Sweet potato (Ipomoea batatas) is a food crop that supplies energy, minerals and vitamins C and B. Some cultivars are very rich in carotenoids (pro-vitamin A). In this study were evaluated and compared the total carotenoids content of two cultivars and the losses on the dehydrated extruded sweet potato flour. Samples from organic and conventional crops were analyzed, in the form of fresh and dehydrated extruded samples. Total carotenoids content of the fresh product, expressed on wet basis, was of 437 µg 100 g-1 for the cream cultivar and 10,12 µg 100 g-1 for the orange cultivar. After dehydration, losses of total carotenoids were of 41% and 38%, respectively. The fresh orange cultivar presented high total carotenoids content in comparison to the cream cultivar. The extruded orange sweet potato flour showed the lowest losses in total carotenoids. Therefore, the processed flour of orange sweet potato could be used to obtain pre-gelatinized extruded flour with high total carotenoids content.

ABSTRACT Paulus, J.M. 2005. Land Productivity, Competition, and Tolerance of Three Sweet Potato Clones Planted as Intercroping with Maize. Eugenia 11 (1): 1-7. A field experiment was conducted in Cikeumeuh Experimental Garden of Food Crop Biotechnology Research Station (BAUTBIO) Bogor to study Land Equivalent Ratio (LER), Competition Ratio (CR), and Stress Tolerance (TOL) of sweet potato and maize. The highest tuber yiled of sweet potato was 16,83 ton ha-[1] gained by CIP-2 at 100 cm planting distance of maize and the highest maize yiled was 4,50 ton ha-1 Cangkuang in intercropping with Cangkung clone. The LER, CR, and TOL, CIP-2 and SQ were suitable for intercrops at all planting distance but Cangkuang was not suitable for intercrops with maize.

Various potentials and challenges in agricultural development in the border region are expected to managed and overcome properly. The participation of all parties, is needed to support this sector. The purpose of study was to determine the basic food crop agricultural commodities that have fast growth and competitiveness in the border region of North Sulawesi. This study uses analytical methods with secondary data. The data analysis determined changes in the structure or performance of the regional economy against higher economic structures (provincial or national) is the location quotient analysis (LQ). To determine the performance or productivity of the work of the local economy by comparing it with the larger using Shift Share Analysis (SSA). The results showed that the most superior commodity and the base in the Sangihe Islands Regency was sweet potato with the LQ value of 12.64, cassava 9.1and peanut 2.96. The results of the Shift Share analysis show that the six agricultural commodities of food crops (lowland rice, dry rice, cassava, sweet potato, peanuts) have not been able to growth in the food crop agriculture sector because it has slow growth.

Agrobacterium rhizogenesandAgrobacterium tumefaciensare plant pathogenic bacteria capable of transferring DNA fragments [transfer DNA (T-DNA)] bearing functional genes into the host plant genome. This naturally occurring mechanism has been adapted by plant biotechnologists to develop genetically modified crops that today are grown on more than 10% of the world’s arable land, although their use can result in considerable controversy. While assembling small interfering RNAs, or siRNAs, of sweet potato plants for metagenomic analysis, sequences homologous to T-DNA sequences fromAgrobacteriumspp. were discovered. Simple and quantitative PCR, Southern blotting, genome walking, and bacterial artificial chromosome library screening and sequencing unambiguously demonstrated that two different T-DNA regions (IbT-DNA1 andIbT-DNA2) are present in the cultivated sweet potato (Ipomoea batatas[L.] Lam.) genome and that these foreign genes are expressed at detectable levels in different tissues of the sweet potato plant.IbT-DNA1 was found to contain four open reading frames (ORFs) homologous to the tryptophan-2-monooxygenase (iaaM), indole-3-acetamide hydrolase (iaaH), C-protein (C-prot), and agrocinopine synthase (Acs) genes ofAgrobacteriumspp.IbT-DNA1 was detected in all 291 cultigens examined, but not in close wild relatives.IbT-DNA2 contained at least five ORFs with significant homology to theORF14,ORF17n, rooting locus (Rol)B/RolC,ORF13, andORF18/ORF17ngenes ofA. rhizogenes.IbT-DNA2 was detected in 45 of 217 genotypes that included both cultivated and wild species. Our finding, that sweet potato is naturally transgenic while being a widely and traditionally consumed food crop, could affect the current consumer distrust of the safety of transgenic food crops.

This chapter studies the ritual conservation of archaic cultigens. Contemporary food-crop agriculture in the region is heavily focused on rice. But tribal mythology, supported by archaeological evidence, suggests that much grain cultivation was preceded by the cultivation of tubers, in particular taro. Myth and ritual depict this process of agricultural change as a contest, as political in effect; and indeed, the history of the development of rice cultivation — especially irrigated cultivation — cannot be told without reference to the rise of central states, which favored rice cultivation as easy to control and tax. State ideologies disparage systems of food-crop production that are less amenable to state control as primitive, as reflected in folk mythology that depicts the earlier forms of cultivation, for example of tubers, as demanding less knowledge. The native mythology and ritual thus represent the terms of a historical contest over rice cultivation that played out over the centuries. The “constitutive absence” of long-gone crops in contemporary myth and ritual affords people a perspective on the present, showing its apparent inevitability as historically contingent. This exemplifies the capacity for “correctives” like ritual and religion to escape the confines of “conscious purpose.”
