GROWTH AND YIELD OF SHALLOTS PLANTED BETWEEN CHILI PLANTS
Get PDFCommunity needs for the shallot commodity take place regularly every day because it is a food flavoring ingredient. For this reason, it needs to be followed by the availability of production supplies that are in accordance with consumer needs. Sigi Regency is one of the centers of shallot and chili production in Central Sulawesi, so far it has not been able to make a real contribution in meeting the needs of the community which tends to increase. This is because the exploitation of shallots and chillies is still monoculture, so the risk of crop failure, production decline and farmers\u27 losses is very high. This research was carried out with the aim to determine the growth and yield of shallots planted with various cropping patterns mong chillies, so that information on suitable cropping patterns can be obtained to ensure the availability of high yields of shallots and chillies to meet community needs. The results showed that (i) various shallot cropping patterns among chilli plants did not significantly affect the greenness of leaves, tuber length, fresh weight per tuber, fresh weight of tuber per clump, harvest index and moisture content of shallot bulbs; (ii) leaf length, harvest age and fresh tuber weight of onion bulbs per hectare planted with different cropping patterns among chilli plants were not significantly different, except with monoculture shallot cropping patterns obtained by longer leaves, shorter harvest age (62.0 days) and the weight of fresh bulbs per hectare is higher (1.83 t / ha) compared to various shallot cropping patterns among chilli plants
WATER CARRYING CAPACITY BASED ON ECOSYSTEM SERVICES IN URBAN AGRICULTURE OF PALU
Get PDFUrban agriculture grows increasingly in tropical countries. It develops not only to feed the growth of the population but also to provide green space, biodiversity, and recreational landscaping. However, developing urban agriculture is facing the problem of water provision. This study examines the existence of agricultural land in Palu, investigates the distribution of agricultural land use in each district, and analyzes the status of environmental carrying capacity for provisioning water. The environmental carrying capacity for provisioning water was assessed based on ecosystem services analysis. The total area of agricultural land in Palu is 5,892.06 ha or about 16.52% of the total area, which spreads in all districts. Three districts recorded have the more extensive agricultural lands, Mantikulore, Tawaeli, and North Palu, of each, has 2188.12 ha (14%), 1090.89 ha (18.51%), and 723.88 ha (12.29%) respectively. The status of water carrying capacity ranged from moderate to high levels, covering an area of ??5,189.95 ha or 88.08% of the total area of ??agricultural land. The low carrying capacity of water provision covers ??689.31 ha or about 11.84% of the total agricultural land. The district of West and South Palu calculated to have the highest carrying capacity. However, both districts experienced a decrease in agricultural land space due to urban development. This study\u27s finding contributes to essential data for relevant authorities in decisions making for sustainable development of urban agriculture in Palu

The second factor consisted of two storage times, namely: one month and two months. The treatments repeated six times, so there were 48 experimental units where each experimental unit contains 50 seeds, and the whole seeds used were 2,400. Data analysis used Fisher\u27s test and continued with 1% Tukey’s HSD test. The results showed that the best storage location was in Kalukubula, both outdoors and indoors. The best storage time was two months. Those produced the highest germination capacity and growth potential and faster germination time, percentage of moldy seeds, and moldy sprouts. 
LAND RESOURCE MANAGEMENT STRATEGY FOR THE SUSTAINABILITY OF THE UPPER WATERSHED OF PALU (Case Study of Miu Sub Watershed in Sigi Regency)
Get PDFPopulation growth and regional expansion has increased land needs for settlement, agriculture, and trade in the Palu watershed causing much pressure on the upper part of the watershed where Miu watershed is situated The general aim of the research was to generate strategy for sustainable land resources management in the Miu watershed as a buffer zone of the Lore-Lindu National Park. The objective of the research were 1) to predict soil erosion and sedimentation, 2) to analyze the feasibility of dominant farming systems, 3) to analyze rural development, and 4) to analyze community preference on land use priority. The erosion and sedimentation, and feasibility research was conducted through soil survey and socio-economic approach. The rural development index was determined using secondary data taken from related institution such as demography, regional structure and infra structure, and industrial-trade condition. The preferential analysis of land use priority for 10 years ahead was done using focus group discussion with farmer community leaders. The soil erosion rate was light - heavy whilst the soil erosion index was low - very high estimated by the USLE. The relationship between the river debit and suspended load at the upper and lower part of the watershed was found to follow the equation of Y= 0.001X1.366 (R2= 0.65), and Y = 0.001 X1.409 (R2 = 0.66), respectively. Three villages included Pakuli, Pandere, and Bolapapu had high index of rural development whereas low index was found in Lonca, Bangga and Tangkulowi. The high-low order of land use priority was agro forestry, cacao monoculture, fresh water fishery, wetland rice, ruminant grazing, mixed culture of rice, soy bean, cassava and maize, and poultry farming
