Abstract

This research aimed to examine the relationship between soil pH, exchangeable aluminum (Al-dd), and available phosphorus (P-available) in Ultisol soil through the application of sago waste compost. The research was conducted in a greenhouse located in Wowawanggu Village, Kadia District, Kendari City. Soil analysis was performed at the Laboratorium Dasar Kimia Analitik, Haluoleo University. The study was designed based on a Completely Randomized Design (CRD) with sago waste compost treatment doses, where each treatment was repeated 3 times. The doses of sago waste compost tested consisted of three levels: 10 tons/ha (KAS1), 20 tons/ha (KAS2), and 30 tons/ha (KAS3). Soil analysis was conducted on pH, Al-dd, and P-available before and after the application of sago pulp compost. Observations after application were made in stages every 7 days with four observations. The results showed that the application of sago waste compost had a significant effect on increasing pH and P-available and decreasing Al-dd in Ultisol soil. There was a very strong relationship between pH, P-available, and Al-dd, as indicated by a correlation coefficient value of > 0.90. The best treatment was shown by KAS3, with a sago waste compost dose of 30 tons/ha.

Abstract

The research aims to determine the main types of pests and the intensity of their damage to chili plants with different cultivation systems. This research was conducted in Konda Satu Village, Konda District, South Konawe Regency. This study consisted of 3 treatments with 6 replications, so there were 18 experimental units. Observational data were analyzed using analysis of variance (ANOVA) and if the results showed significant differences then it was continued with the Least Significant Difference Test (LSD) at the 95% confidence level to find out the best treatment by testing the differences between all treatments. Then test further LSD0.05. This study used three cultivation systems as treatments, namely the Conventional Cultivation System (Without Application of Biofresh Fertilizer + 100% Inorganic recommended dose + Use of Plastic Mulch), Semi-Organic Cultivation System (Application of Biofresh Fertilizer 50% recommended dose + 50% Inorganic of recommended dose + Application Phymar C Botanical Pesticides + Use of Plastic Mulch), and Organic Cultivation Systems (100% recommended dosage of Biofresh Fertilizer Application + Phymar C Botanical Pesticide Application + Organic Mulch). The results showed that the main pests that attack chili plants are armyworm pests (Spodoptera litura), fruit fly pests (Bactrocera sp.) and Aphids pests (Aphididae). The lowest damage intensity of armyworm pests was in the organic cultivation system of 18.08%, the lowest intensity of fruit fly pest attacks was in the semi-organic cultivation system of 31.81%, the lowest intensity of attack by aphids was in the semi-organic cultivation system of 12.59%.

Abstract

This study was to determine differences in the distribution of photosynthate of vegetative phase of several varieties of soybean (Glycine max L. Merril) cultivated on acid soil of Southeast Sulawesi. This research was conducted in the sub district Anduonohu, Poasia district and at Agrotechnology Laboratory, Faculty of Agriculture University Halu Oleo, Kendari from July to October 2013. The research design used was randomized block design (RBD) with three replications. Variety treatment consisted of varieties Kaba, Argomulyo, Tanggamus, Grobogan and Gema.  The variables observed in this study were root dry weight, stem dry weight, leaf dry weight, stem dry weight, and branch dry weight. Results of statistical analysis of the data showed that the treatment affected the distribution of photosynthate on different plant varieties. Different varieties gave significant effect on root dry weight, stem dry weight, leaf dry weight, branch dry weight.Keywords : Acid soils, distribution of photosynthate, soybean, varieties

Abstract

This study aimed to determine the changes in some chemical properties of coastal soil and the growth of pakcoy (Brassica rapa L.) given chicken manure and to obtain a treatment that changed the chemical properties of coastal soil and the growth of pakcoy (Brassica rapa L.) was more good. This study used a randomized block design (RBD) consisting of 4 treatments, namely A0 (without chicken manure), A1 (100 g chicken manure polybag-1), A2 (200 g chicken manure polybag-1), and A3 (300 g chicken manure polybag-1). Soil analysis was carried out at the Nanotechnology Laboratory, Halu Oleo University. This study showed that chicken manure increased the nutrient content of total N-, P-available, C-organic, and pH in coastal soil, with a dose of organic fertilizer that gave the best effect, namely 100 g polybag-1.
