Abstract

Cultivated potato (Solanum tuberosum) is an economically important crop world wide as shown by its increasing demand each year.  However, the relatively high demand of this crop is hard to meet due to leaf miner flies (Liriomyza huidobrensis) attack which could reduce potato production up to 70 percent.  The devastation is due to the ability of the flies’ imago to suck up leaf liquid and then lay their eggs which in turn develop into larvae which fed on the potato leaves.  To overcome this problem, it was necessary to assess the heritability resistance of some potato varieties to leafminer flies.  Therefore, the aim of the present study was to identify some parameters genetically resistance to leafminer flies on the potato plant. The study took place in Ngadas Village, Sukapura District of Probolinggo Residence from June to August 2007.  L  huidobrensis flies and six potato varieties such as Granola, Granola Kembang, Granola Lembang, HK, Atlantik, and Sulur were used.  The study results showed that trichome density of lower (73.29%) and upper (67.76%) leaves had high resistance heritability assessment. Such parameters with high heritability assessment can be used as selection criteria for plant breeding program.

Abstract

The research about the understorey plant community in the Lore Lindu National Park Central Sulawesi has been conductedfrom March 2004 to February 2005. The research used multiple plots by survey methods with plot size 2X2 m as much 25 plots eachforest type. There were 2 types of observed forest namely: “wana” (primary forest) and “pangale” (primary disturbed forest). Theresult showed the understorey plant composition was differ in two forest types observed. “Wana” were dominated by Pilea wightii(Urticaceae), Curculigo orchimoides (Hypoxidaceae), Chionanthus ramiflorus (Oleaceae) Callophyllum soulatri (Clusiaceae)whereas “pangale” were dominated by Diplazium angustippina, Zizhipus sp (Rhamnaceae), Freycinetia angustifolia, Castanopsisaccuminatissima. The Shanon diversity index of wana (3.25) was higher than pangale (3.06).Keywords : Understorey plant, diversity, and Lore Lindu.

Abstract

Aspergillus niger produces α-amylase and glucoamylase enzymes whichenable starch to be broken down into simple glucose then fermented into ethanol.  The growth of A. niger is directly related to food substances within the medium.  A. nigeralso generatessuch enzymes as amylase, amyloglucosidase, pectinase, cellulose, glycoside that can break down urea into amino acid and CO2.  The research objective was to find A. Niger fungi isolate which potentially has antagonist characters against the growth of P. Palmivora  fungi in cacao fruits. The research was conducted in the Pest and Disease Laboratory, Faculty of Agriculture of Tadulako University from September to December 2015.  The research results showed that 20 isolates of A. niger found are potentially utilized as biological control agents of fungal antagonist against P. Palmivora in four villages where cacao are produced i.e. Sidondo, Lalundu, Towiora and Martajaya.  The results of  in-vitro inhibition test suggested that two isolates best in suppressing the growth of P. Palmivora causing cacao fruit rot are Lalundu isolates (rate of inhibition of 63.65%) and Martajaya isolates (rate of inhibition of 63.63%)Key Words: Aspergillus niger, fungi, antagonis, Phytophthora palmivora.

Abstract

This research aimed to identify : (1) factors influencing production of hybrid and non-hybrid corn, and (2) the disparity of income between hybrid and non-hybrid of corn agribusiness. The research was conducted in 3 villages of Palolo Subdistrict,  namely: Bobo, Bunga and Berdikari. Sixty six farmers (34 hybrid corn farmers and 32 non-hybrid corn farmers) were chosen as sample respondents based on randomized sampling. The results of the research showed that all variables observed were found to influence the hybrid corn production, except for experience in agribusiness. Similarly, production of the non-hybrid corn was also influenced by all variables, except for the amount fertilizer used and experience in agribusiness. The income of the hybrid corn agribusiness for one planting season was IDR 4,882,225.79 ha-1 higher than IDR 2,691,452.10 for the income of non-hybrid corn agribusiness

Abstract

One main constraint for growing wetland rice in Inceptisol is low soil fertility.  Soil acidity (pH), CEC, C-organic are several indicators used to determine the level of soil fertility. To overcome these kinds of problems, such organic materials as rice husk biochar can be added to the soil in order to modify the soil chemical properties.  This research compared treatments of   different biochar rates with various fineness degrees on soil pH, CEC, C-organic, and  available P.  The research results showed that after incubation for 21 days at room temperature, the best interactionshown by the biochar at the rate of 15 ton ha-1 with 60 mesh particle size can reduce the soil pH by 5.19% from 7.7 to 7.3, increase the soil CECby 32.92% from 16.37 to 22.25 cmol (+) kg-1, improve the soil C-organic by 33.94% from 1.09% to 1.46%, and enhance the soil available phosphor by 277.08% from 12.61 ppm to 47.55 ppm.Keywords: Incubation, Rice HuskBiochar,  and  Soil Chemical Properties.

Abstract

ABSTRACT The objectives of the research was to discover the income of farmers and to determine the development strategy of red chili farming system in Tibo village of Donggala district, Central Sulawesi.   Respondents of twenty three family heads who have been cultivating red chilli were selected from farmer population along with five stakeholders, three local extension workers, and the head of the village. Data collected was gathered through observation, interview and Focus Group Discussion (FGD).  The average income of the red chili farming system was found to be IDR 19,471,130/ha/planting season, while the R/C ratio was 3.90.  These results suggested that the red chilli farming is very profitable to be developed. The Strength Weakness Opportunities and Threats (SWOT) analysis showed that the strategy of developing the red chilli farming in Tibo village was positioned in the quadrant II indicating Strength-Threats strategy to support diversification strategy.  These strategies include:  (1) to increase the availability of potential land and to make the most of the manpower availability for the development of this potential commodity (red chilli), and (2) to take advantage of the experience and high motivation of the farmers as well as to improve the farmer knowledge.  The Quantitative Strategic Planning Matrix (QSPM) analysis indicated that the second strategy is the most feasible program that could be implemented with the total value of attractiveness (TAS) was highest (6.624) Keywords: Development Strategy, Income Analysis, Red Chili.

Abstract

The objectives of this study were to evaluate bioactive compound contents of the ”Sidondo” plant (Vitex negundo L.) especially those compound that are potentially used as botanical pesticide and to test the plant extract influence on tested Spodoptera exigua and Plutella xylostella larvae mortality and toxicity. This study was conducted in Plant Protection and Biotecnology Laboratories, Faculty of Agriculture, Tadulako University from March to October 2008. Results of the study indicated that     crude extract of the V. negundo could kill both S. exigua and P. xylostella larvae. The highest mortality rate for S. exigua (32%) was found when the plant was extracted with ethanol and for P. xylostella (27%) was seen with methanol extraction. The effective extract concentration was 0.3% for S. exigua and 0.2% for                               P. xylostella.  The extract sub-lethal concentration (LC50) was 0.49% for S. exigua and 0.42% for P. xylostella.  The extract of V.  negundo contained Saponin which could be used as a botanical insecticide active ingredient

Abstract

This study aimed to determine the influence of atonic concentrations which can increase plant growth and yield of shallot (Allium cepa L. Aggregatum Group) of Lembah Palu variety.  This study was conducted from February to May 2015in Bulupountu village, Sigi District, Central Sulawesi Province.  This study used a Randomized Block designin which grouping was based on diameter of shallot bulbs. Five treatments with four replicates were applied including Control (A0), 0.25 ml atonic/l water(A1),0.50 ml atonic/l water (A2), 0.75 ml atonic/l water(A3), and 1.0 ml atonic/l water (A4).Datawas analyzed using analysis of variance (ANOVA) followed by a HSD test at 5% if the atonic effect was significant.  The atonic concentrations significantly affected the growth and yield of Lembah Palu shallot variety in which the best treatment was found in the application of 1.0 ml atonic/l water.  Keywords: Atonic, Lembah Palu shallot variety.
