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

Pectin is a natural substance found in most food crops. In general, pectin extraction uses mineral and organic acids, such as sodium hexametaphosphate acid, sulfuric acid, hydrochloric acid, acetic acid, nit citric, and citric acid. The study aimed to obtain the concentration of HCl, which gave the best value for the physical and chemical properties of passion fruit pectin. This study was a completely randomized design. The tested factor was 400 ml HCl solution with five treatment levels of HCl concentration: 1 N; 1.5 N; 2 N; 2.5 N; and 3 N. Each treatment was repeated three times, and therefore 15 experimental units were tested. The variables observed were pectin yield, methoxyl content, galacturonic content, esterification degree, clarity, water content, and ash content. The results showed that the 2.5 N HCl concentration resulted a yield value of 27.47%, methoxyl content 5.20%, galacturonic content 121.62%, esterification degree 24.26%, clarity 14.65%, water content 4.37 %, and 0.54% ash content, so the 2.5 N HCl concentration was the HCl concentration that gave the best effect on the physical and chemical properties of passion fruit pectin extraction.

Abstract

Before crossing plants, it's critical to understand their morphological characteristics. Differences in plant morphological features distinguish the advantages of each plant. The objective of this study was to determine the morphological characteristics of superior purple and local red corn cultivated at the height of 22 meters above sea level, as well as their adaptability. Kalukubula Village, Sigi Biromaru District, Sigi Regency, Central Sulawesi was the site of this study. The research took place between October 2020 and February 2021. A Randomized Block Design was used in this investigation, with two corn kinds as treatments: The experiment was repeated 16 times with purple superior corn and red corn, yielding 32 experimental units. The quantitative data was examined using ovarian analysis (ANOVA) followed by a 5% Tukey HSD test to assess the difference between the two corns. Plant height, number of leaves, leaf length, stem diameter, age of male flower appearance, harvest age, fruit diameter with husk, length of cob, number of seeds per fruit, the weight of kernel per fruit, and dry kernels production of tons/ha were all found to have a higher growth rate than purple corn kernels. The qualitative characters of superior purple corn kernels include: leaf veins and leaf bases are purple, stems are purplish-green, female flowers are white with anger, the husk is purplish-green, and kernels are purple-black. Local red corn include white leaf veins, light green leaf bases, purple stems, light green female flowers, purple husk, and red kernels.

Abstract

The purpose of this study was to determine the effect of shade level on the growth and yield of shallot plants from seed. This research was conducted in Lolu Village, Sigi Biromaru District, Sigi Regency, Central Sulawesi Province. The time of this research is from January to March 2021. This research was conducted using a Randomized Block Design (RAK) which consists of 5 levels of shade, namely N0 = No Shade, N1 = 9% Shade, N2 = 18% Shade, N3 = 38% Shade and N4=Shade 50%. Each treatment was repeated 3 times so that there were 15 experimental units. Parameters observed were plant height, number of leaves, number of tillers per clump, number of tubers per cluster, tuber circumference, fresh weight of tubers per cluster, weight of tuber per tile, tuber weight per ha and weather variables. The data obtained from the study were then analyzed using analysis of diversity (ANOVA). If the results of the diversity analysis show a real or very real influence, then it is continued with the Honest Significant Difference (BNJ) test at 5% level. The results of this study showed that the level of shade had a significant effect on the observed variables of tuber fresh weight, tuber weight and tuber weight per hectare, but on the variables of plant height, number of leaves, number of tillers, number of tuber clumps and tuber circumference had no significant effect. The 18% shade gives the best shallot crop yields.

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

The use of antibiotics as growth promoters (AGP) in poultry feed aims to stimulate growth and prevent disease. However, the use of antibiotics in animal feed has been banned spread of resistant bacteria which can be harmful to human health. The use of natural compounds, especially essential oils, as a natural alternative for antibiotics. The aim of the study was to evaluate the inclusion of eugenol clove leaf oil as a feed additive to replace antibiotics in feed on immune organs and growth performance of male laying hens. Experiment was designed in Completely Randomized Design with 5 treatments and 4 replicates. The study Animal used 120 DOC (Day Old Chick) of male laying hens. Treatments consist of: P1 = Basal feed; P2 = Basal feed + 0.005% tetracycline ; P3 = Basal diets + 0.5% eugenol; P4 = Basal diets + 1.0% eugenol; P5 = Basal diets + 1.5% eugenol. Variables observed i.e.: immune organs (thymus, bursa fabricus, spleen, liver) and growth performance (weigh gain, feed intake, protein intake, energy intake, feed efficiency). The statistical analyses were carried out using Anova and LSD test. Results were shown high significant (P<0. 01) effects on thymus (immune organ) and growth performance (weight gain, feed intake, protein intake, energy intake, feed efficiency) of male laying hens. However, no significant (P>0.05) effects on bursa fabricus, spleen, and liver (immune organs). Our finding suggest that the use of eugenol clove leaf oil as a substitute for antibiotics in feed, with a level of 0.5%-1.0% of male laying hens resulted similar response to the use of tetracycline 0.005%.
