Abstract

Cacao is one of the prioritized commodities of crop plantations in Central Sulawesi. However, the main obstacle faced in the cultivation of cocoa plants is plant pest organisms (OPT). One of the most frequently OPT encountered is black pod rot caused by Phytophtorah palmivora fungus. Based on the above description, this study aimed to determine the resilience of some cacao clones on the development of P. palmivora. Cocoa fruit samples of six different clones were taken from people plantations in Uenuni village, Palolo sub district of Sigi Regency, and brought to the Laboratory of Phytopathology Plant where their resistance to black pod rot disease was tested using a Detached Pod method. The six clones used included Local II (Criolo), M01, Lokal III (Mulia), CRD 60, Local I (Forestero), and Local IV (Hibrida). This study used a Completely Randomized design (CRD) with P. palmivora as a factor. The fungus was inoculated to the fruits of the six cacao clones. An experimental unit consisted of three pieces of cocoa for each clone tested and replicatedthree times.  Observations were made on the area size of spots on the fruit’ssurface and itsincreasingsizeper day for seven days. After seven days, the largest spot area of 350.79 cm2 was found in the Lokal III (Mulia) clone with the fastest rate of increasing spot size of 58.11 cm2 per day in average and with 0.63 cm thickness of the outer skin and with 0.43 cm thickness of the inner skin suggesting that this clone is very prone to P. palmivora attack. The lowest spot area found in the CRD 60 clone was 12.86cm2 with the rate of increasing spot size 1.91 cm2per day in average, and with 1.03 cm thickness of the outer skin and with 0.77 cm thickness of the inner skin suggesting that this clone belong to a group resistant to P. palmivora attack. Keywords: Cacao clone and Fungi P. Palmivora.

Abstract

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.
