The aim of this study was to evaluate the performance of several Sorghum bicolor cultivars as forage on a dry land with pH of 5.4, N of 0.08%;  C/N of 9%, P of 0.06% and K of 0.01%. Nine cultivars of S. bicolor (Super 1, Super 2, Numbu, Kawali, G2, G5, PAC 537, PAC 593 and PAC 501) were evaluated. Plot size was 16 m2 with space planting of 15 x 75 cm. The experimental design used was randomized block design with three replications.  Parameters observed were plant height, time of flowering, forage production and quality. The result showed that the primary plant growth was not different in all cultivars. In the 65 days old primary plant,  the Super 2, PAC 537 and Kawali had no flower yet. Biomass production varied in primary plant between cultivars of 11.35 - 26.17 kg/16 m2. The highest biomass production was obtained in PAC 537 of 26.17 kg/16 m2 (16.34 t/ha) which were significantly higher than G2 of 11.35 kg/16 m2 (7.09 ton/ha) and was not significantly different with other cultivars. In the 45 days ratoon I, Super 2, G5 and Super 1 showed faster growth. Biomass production increased in the ratoon I around 19.88 kg/16 m2 (12.42 ton/ha). PAC 537 produced the highest biomass of 30.14 kg/16 m2 (18.84 ton/ha) and was not significantly different with other cultivars, except with the G2. Biomass production of ratoon II decreased around 1.83 kg/16 m2 (1.14 t/ha)–4.77 kg/16 m2 (2.98 t/ha) and increased in the ratoon III of 15.72 kg/16 m2 (9.82 t/ha)–26.05 kg/16 m2 (16.28 t/ha). The quality of forage ratoon I was better compared to the primary plant with the lowest one was in ratoon II. It could be concluded that Super 1, Super 2 and PAC 537 cultivars might be recommended as potential forage.

Fungus Beauveria Bassiana

Cocoa pod borer Conomorpha cramerella snellen (lepidoptera: gracillaridae) is one type of the key pest which is highly responsible for drilling cocoa, which then causes the production and quality of cacao to decrease. The use of entomopathogenic fungus is one of the alternatives to cope with it. By invecting and developing within the insect, such a fungus can cause the insect to suffer from diseases which will then be responsible for their death. Beauveria bassiana are types of the entomopathogenic fungus which are used for controlling cocoa pod corer, as they are able to infect the pest trough the enzyme or toxin produced, which then leads to its death. This study aims at an effectiveness test of entomopathogenic fungus Beauveria bassiana against cocoa pod borer. This research was conducted at the Laboratory Udaya University in Bali from May to November 2010. The experimental design employed was randomized complete block design (RCBD) wich was made up of four treatments such as B0 (Control), B1 (B. bassiana in which the spore density was 105 spora/ml/); B2 (B, bassiana in which the spore density 106 spora/ml); B3 (B. bassiana in which the spore density was 107 spora/ml).  The result shows that the Larvae CPB which was infected by B. bassiana shows different treatments and responses than control. The fastest death of the larvae CPB took place on the treatments and responses than control. The fastest death of the larvae CPB took place on the treatment of B. bassiana in which spore density 107. The fastest appearance of spore took place on the treatment five days after inoculation. The fungus of B. bassiana at the spore speed of 105 and 107 caused all the larvae CPB 100% to die at five days inoculation.
