Abstract

The purpose of this research is to know the effectiveness of insecticide type to population, Liriomyza sp attack and onion plant production. The study was conducted from February to November 2017 in Guntarano Village and at the Pest and Disease Plant Laboratory University of Tadulako Palu. This study used Randomized Block Design consisting of 4 treatments, namely control, M.anisopliae, citronella extract and insecticide Dimehipo. The results showed that the type of insecticide applied to onion crops affected the population and the attack Liriomyza sp. as well as onion plant production. Imago population Liriomyza sp. the highest was in the control treatment of 4.56 tail / trap compared to the treatment of insecticide Dimehipo 1.39 tail/trap while the treatment of gray and M.anisopliae extract of 2.22 tail / trap and 2.11 tail / trap. Attack  Liriomyza sp. highest in the control treatment was 21.2% compared with the treatment of  M.anisopliae 16.27%, the treatment of citronella 18% and the lowest in the treatment of insecticide Dimehipo 13.13%. The highest production was in the treatment of insecticides Dimehipo 6.87 tons / ha, M.anisopliae 5.11 tons / ha, citronella extrack 4.85 tons / ha and control of 3.10 tons / ha. Thus an effective insecticide suppresses the intensity of the attack, the population of Liriomyza sp. and increase the production of onion crops, namely insecticide Dimehipo.

Abstract

Bactrocera sp. is one of the important pests on crops of chili. Losing of the results caused by this pest attack can reach 80%, and even can be 100% if the control is not done immediately. The purpose of this research is to know the influence combination factors of color and the height of the traps on the number of fruit flies trapped in red chili. This research used Randomized Block Design (RBD) with factorial pattern consisting of 2 factors that are first factor consisting of yellow trap (W2), orange (W1), and clear (W3) and second factor is height of trap, that are height above of 50 cm ( T1), height of 75 cm (T2), and height of 100 cm (T3) respectively applied by Methyl eugenol. The research results showed that (W2, T2) (yellow and height of 75 cm) more effective control of fruit flies on Chili, average of  fruit flies trapped at the height and color is as much as 1758, and of the results of the yield from a height and color also effective because the average yield reached 2.28 kg/week when compared with the results of other productions. The use of methyl eugenol is very effective with the high number and variety of fruit flies trapped by 9113 with four types of fruit flies.

Abstract

This study aims to analyze the income and feasibility of lowland rice farming system on direct spreading seed system. This research has been conducted from July to August 2017. Determination of location is done by purposively with the consideration that Dolago Village is one of rice production area with productivity of 5.09 ton/ha. Respondent determination was done by using simple random sampling method (Simple Random Sampling). Samples taken as many as 31 respondents of farmers' households from rice farmer population in Dolago Village as many as 108 farmers /household with error rate (15%) who work on  paddy. The analysis used in this research is income analysis (π) and feasibility (R/C-ratio). The result of the analysis showed that the average income of rice farmer in one season planting season in Dolago Village is Rp. 10.759.370/1.25ha/ Season Planting or Rp. 8.607.496/ha/ Season Planting. The results showed that Revenue of Cost Ratio (R/C) of lowland rice farming system of direct seeding system in Dolago Village, South Parigi Subdistrict of Parigi Moutong Regency is feasible to be cultivated. This is evidenced by the value (R/C) obtained by 2.21. This means that every expenditure of Rp. 1 will generate revenue of Rp. 2.21.

Abstract

Cocoa (Theobroma cacao L.) is a plant with high economic value, but in its cultivation technique, is inseparable from pest attack, one of which is cacao fruit borer (Conopomorphacramerella). In an effort to control it, can take advantage of soilborne entomopatogenic fungi found in several layers of soil on cocoa plantations.The aims of this study were to determine the type of entomopathogenic fungi and its effect on bait insects (Chrysalis of C. cramerella). The research took place from August 2017 to completion. Sampling was done at Cocoa Plantation then tested further in Laboratory of Plant and Disease, Agricultur Faculty of Tadulako University.This study used Randomized Complete Design (RCD) method consisting of 3 treatments, namely: Soil on horizon O (L1), horizon A (L2), and horizon E (L3) resectively. Isolation of the fungus was done by using bait insects (Chrysalis of C. cramerella) obtained from the field. Identification of fungi was done macroscopically and microscopically. There are 4 genera of entomopathogenic fungi that can be identified which are Aspergillus, Beauveria, Verticillium and Fusarium.The results showed that the percentage of mortality of test-infected fungi in the horizon O was 20 (100%), A horizon was 20 (100%), and E horizon was 15 (60%).

Abstract

This study aims to determine the physical properties of the soil at various slopes of  watershed Poboya Palu City so that it can be used as a reference / consideration in the management of the physical properties of the soil, so that the land can be properly utilized. This research is a descriptive exploratory approach of variables through field survey and supported the results of laboratory analysis of the soil in the Environment Faculty of Agriculture, University Tadulako. This research was conducted in June 2015 and September 2015. The results showed that the physical characteristics of the soil at various gradients of watershed Poboya highly variable, namely the soil texture is dominated by medium-sized particles with a class of argillaceous texture, permeability tend fast to very fast, very high porosity, soil bulk density is relatively modest, and the organic matter content is low to moderate. Based on the physical properties of soil slope changes the value of the texture in the form of sand, silt, and clay is low, increased permeability, increased porosity, bulk density decreases, and increased organic matter. Vertically, the physical characteristics of the soil changes according to the depth value, the texture in the form of sand, silt, and clay is low, permeability increased, decreased porosity, bulk density increased, and organic matter decline.

This researchaimed to determinethe effect of cow manureaddition to soil physicalpropertiessoil and tomatoplant yield. The research was conducted during September toDecember 2014in BulupountuVillage, Sigi Biromaru Sub District, Sigi Regency, Central Sulawesi Province.This research used a Randomized Block Design (RBD) with cow manurerates as the experimental treatments. The rates included without fertilizer (control), 15Mg ha-1, 30Mg ha-1 and45 Mg ha-1.Eachtreatment was replicated3timesso thatthere were 12experimental plots.Rising the cow manure rate significanltly increased plant height. Similar results also indicated by the number of tomato fruits except at 45 Mg ha-1the fruit number decreased. Applying 30 Mg ha-1 resulted in highest number of tomato fruit. The addition of cow manure significantly improvedsoilphysical properties. Soil bulk density, porosity and permeability declined significantly to only 1,56 g cm-3, 35.45 % and 2,18 cm jam-1 when the rate of cow manure increased to 45 Mg ha-1.
