Abstract

Sweet orange (Citrus sinensis L.) is an important fruit produced and consumed worldwide and it’s an excellent source of vitamin C. However, citrus industry in Ethiopia is at an infant stage; which is particularly due to shortage of improved and adapted cultivars and their distribution. Considering these, six sweet orange cultivars were evaluated to select adapted, high yielding and quality cultivar/s. Different growth, phenological, yield and yield component data were collected and analyzed using SAS. Days to maturity was also highly significantly (p<0.01)) affected by cultivars in 2017 cropping year. Fruit weight without rind (flesh weight) and juice weight were highly significantly (p<0.05) affected by cultivars in 2018 harvesting year. Marketable yield, unmarketable yield, and total yield tree-1 were significantly affected by cultivars in both 2017 and 2018 harvesting year. O. Valencia is late matured cultivars which took 1622 days from planting to first harvest. While, P.W.N. is early matured cultivars with average number of days of 1104 from planting to first harvest. In 2017, Hamlin, gave the highest marketable fruit yield tree-1 (68.61 kg) and total yield tree-1 (68.94kg). Jaffa gave significantly the maximum marketable fruit yield tree-1 (197.24 kg) and total yield tree-1 (198.81 kg) in 2018 cropping year. In 2019 harvesting year, Hamlin gave the highest marketable (63.3 kg) and total (64.02 kg) fruit yield tree-1. In average Jaffa and Hamlin gave the maximum marketable fruit yield tree-1 from the three consecutive harvesting years with mean value of 95.38 kg and 72.24 kg respectively. So, in Raya Azebo, and other areas having similar agro-ecologies Jaffa and Hamlin cultivars are recommended. Further, studying the nutritional content and water requirements of these cultivars are suggested.

Abstract

Central Sulawesi's agricultural sector is classified as a substantial sector. This study aims to identify the existence of the agricultural sector in the economic structure of Central Sulawesi. Data analysis used Location Quotient (LQ), Dynamic Location Quotient (DLQ), and Shift Share Analysis methods. The data used is based from the Central Statistics Agency for Central Sulawesi and Indonesia in 2015-2020 based on constant prices. The results showed that the agricultural sector of Central Sulawesi was classified as the base sector with the highest average LQ value and was followed by the mining and quarrying sector. Meanwhile, the results of the DLQ analysis show that the agricultural sector is threatened with repositioning in the future. The combined analysis of LQ and DLQ indicates that the agricultural sector in Central Sulawesi is on a basic non-prospective. The results of shift-share analysis (Nij) show that the highest performance in the agricultural sub-sector is produced by the plantation sub-sector and the fishery sub-sector. The industrial mix value (Mij) from the agricultural sector and all sub-sectors mostly shows negative numbers, so only three agricultural sub-sectors, including the developed sector in Central Sulawesi Province include the horticulture sub-sector, livestock sub-sector, and fishery sub-sector. Based on the value (Cij) of the agricultural sector, it shows a negative number, so the sub-sectors that need to be improved include the food crops sub-sector, the horticulture sub-sector, the plantation sub-sector, and the fisheries sub-sector. It is necessary to pay attention to increasing labor wages in the agricultural sector and improving the performance of agro-industry in Central Sulawesi to create added value.

Abstract

Indonesia is listed as one of the countries with a high rate of deforestation. This deforestation occurs in almost all islands in Indonesia, including Sulawesi. Deforestation analysis needs to be carried out to determine the rate of change in forest cover and the factors that cause it, so that forms of forest management can be planned to achieve sustainable forest management This analysis is expected to fulfill the need for information on how the vulnerability of deforestation occurs spatially, where the locations of deforestation occur and what factors encourage deforestation and forest degradation. The study found that the rate of forest decrease from 1990 to 2020 was 328 hectares/year with the highest rate was from 1990 to 2000 with rate of forest decrease 690 hectares/year. The deforestation located in four area that has difference land cover change. Area 1 changed to settlement and dry land agriculture, area 2 changed to cocoa plantation by the local community planted in 2000s, area 3 changed to cocoa plantation by the local community planted in 2010s. Area 4 changed to open area/bareland indicated after ilegal logging occurred since 2000.
