Abstract

The objective of this research was to identify entomopathogenic fungi associated with green leafhopper (Nephotetix virescens) and to determine its virulence toward N. viresnes mortality. The indicators of pathogenicity were symptoms, time of symptom appeared, and mortality of green leafhopper after inoculation of the entomopathogenic fungi. The research was conducted in three phases. The first phase was collecting green leafhopper infected by entomopathogenic fungi in the field. The second phase was isolation, inoculation, and re-isolation of entomopathogenic fungi from the infected green leafhopper (wereng). The third was pathogenicity assay conducted in the Laboratory of Plant Pest and Disease, Faculty of Agriculture, Tadulako University. The research was conducted for four months from February to May 2010.  Five isolates of entomopathogenic fungi were collected in Donggala Regency: Metharizium sp., Asperigillus sp., Beauveria sp., Cladosporium sp. and Fusarium sp. Two isolates were found potential as entomopathogenic             fungi: Metarhizium sp. and Beauveria sp. Mortality of nimpha green leafhopper (wereng hijau) caused by both fungi were 80.75%, and 80.25% respectively.

ABSTRACTMost upland soils are poor in organic matter and have high temperature. The utilization ofmulch and organic manure with appropriate dosage are expected to enhance the physical andchemical conditions of the soil and the production of shallot. This study aimed to determine the effectof applying various types of mulch and cow urine bioculture on the growth and yield of shallot. Theresearch was conducted in March to June 2017 in Oloboju Village, Sigi Biromaru District, SigiRegency, Central Sulawesi Province. A randomized block design factorial with two factors was usedin this study. The first factor was the various types of mulch, namely: Gliricidia sepium leaves, ricestraw, and plastic mulch. The second factor was the frequency of bioculture, namely: without cowurine bioculture, two times and four times application. Thus, there are nine in the combination oftreatments and repeated three times and therefore there were 27 experimental units. The resultsshowed that interaction of rice straw mulch and four times cow urine bioculture application have avery significant effect on the growth and production of shallot. The use of 3 ton ha-1 rice straw andfour times cow urine bioculture application frequency produced 11.25 ton ha-1 shallot bulb.Keywords: chemical properties, gliricidia leaf, organic matter, rice straw, soil physicalABSTRAKLahan kering umumnya memiliki kandungan bahan organik yang rendah dengan suhu yangtinggi.

Abstract

This experiment aimed to determine the best growing media composition and coconut water in stimulating the growth of pepper plant cuttings. It used a two factorial randomized block design. The first factor was various proportions of media compositions of manure, sand and top soil i.e. 1:4:12; 1:4:6; and 1: 4:4. The second factor was different rates of coconut water i.e. A0           (no coconut water added), A1 (40 cc), A2 (80 cc), and A3 (120 cc). There were 12 combination treatments and each was replicated three times with each treatment consisting of three plants. Parameter observed included shoot length, leaf number, leaf area size, root length, and fresh root weight. The research results showed that there was no significant interaction effect between         the media composition and the coconut water on the shoot length at 45 days after planting (DAP), 60 DAP, and 90 DAP but it was significant at 75 DAP. The interaction effect was also significant on the leaf number at 60 DAP. Only the coconut water had significant effect on the total leaf area size, the root length, and the fresh weight. The stimulation of the pepper cutting growth was best under the 120 cc coconut water treatment per week and the sand, manure and top soil proportion of 1:4:4 treatment. Key Words : Coconut water, pepper cuttings, and planting media

Abstract

Shallot growth is strongly influenced by climatic factors and available soil nutrients. By doing appropriate fertilization, the plants will get the nutrients needed. This study aimed to determine the effect of cow urine bioculture (liquid organic fertilizer) rates on shallot growth and yield. The research was conducted in Oloboju village, Sigi Biromaru sub district, Sigi Regency, Central Sulawesi Province from March to June 2017. The study used a randomized completely design which consisted of with no application of bioculture liquid fertilizer (B0), 250 L ha-1bioculture liquid (B1), 500 L ha-1bioculture liquid (B2) and 750 Lha-1bioculture liquid (B3). Each treatment was replicated four times, so there were 16 experimental units. Each unit of experiment consisted of 260 plants so that a total of 4160 plants were grown. The results showed that the bioculture liquid fertilizer applied at the rate of 750 L ha-1 resulted in significantly higher plant height, bulb diameter, bulb water content, number of tillers per hill, fresh weight of bulb,  bulb bulk weight, dry weight of plant and bulb yield per hectare compared to the other treatments. Adding the bioculture liquid fertilizer at the rate of  750 L ha-1  produced  shallot bulb of  9.27 ton ha-1.
