Abstract

The use of Bacillus spp. Bacteria as biocontrol agents is one alternative disease control for Fusarium wilt Fusarium oxysporum f.sp. Lycopersici on chilli plant . this study aimed to determine the effectiveness of Bacillus spp. As a biocontrol agent in various ways of application to control Fusarium wilt disease in pepper in in-vivo. Experiments were prepared  using  two  factor  factorial  in  a  completely randomized design  (CRD).  Factor  1 (Applications) consisted of levels, namely: application of biocontrol agent Bacillus spp. M11 isolates (B1), application of biocontrol agents Bacillus spp. isolates F133 (B2), and application biocontrol agent Bacillus spp. mix. M11 isolates and isolates F133 (B3). The second factor (time of inoculation/application) consisted 3 levels, namely: inoculating the seed (S1), inoculation of Bacillus spp. simultaneously with pathogen inoculation (S2), inoculation of Bacillus spp.  one week after pathogen inoculation (S3), to see the effect of the two isolates of Bacillus spp. that the latent period, the biocontrol agents Bacillus spp. mix isolates M11 and F133, was the best treatment with the longest latency period of the disease (16 hsi), the best plant growth by plant height reached 57,39 cm, and the lowest disease incidence and severity were 12,96 % and 11,11 %, respectively interaction between agent Bacillus spp. mix. Isolates M11 and F133 at the time of application on seed significantly affected the incidence of disease and plat height. Keyword: biocontrol agents, Bacillus spp., and Fusarium oxysporum f.sp.

Abstract

This study aimed to evaluate the resistance of sorghum cultivars to wilt fusarium. This research was arranged in a randomized block design, with six  treatments [brown  sorghum, white sorghum and  red  sorghum with no inoculation fusarium, brown    sorghum, white sorghum  and  red  sorghum with  inoculation  fusarium]  with  3  (three)  replications. Data observed were plant height, leaf number, leaf area, and heaviest of grain weight for vegetative observation, while for disease character was disease incidence. The results showed that none of sorghum cultivars evaluated showed resistance to wilt fusarium infection. The tolerant response to wilt fusarium  was observed on brown sorghum, whereas red and white sorghum were  susceptible to wilt fusarium. The heaviest of  grain weight was found in brown sorghum (27.86 g/penicle). The wilt fusarium caused disease incidences ranging from 33.33% (brown sorghum)  to 50% (red sorghum). Keywords: cultivars, disease incidence, fusarium, sorghum, resistance

Abstract

The research to study the effects of arbuscular mycorrhiza fungi (AMF) and organic nutrients to enhance the growth of chili has been conducted in Experimental Field, Faculty of Animal Husbandry and laboratory of Agrotechnology, Halu Oleo University, from June to November 2012.  The research was based on the split-plot design with a randomized  block design pattern (RAK) of two factors: Organic Nutrition as the main plot and AMF as subplot. Organic nutrients as the main plot consisted of three levels, namely: without organic nutrition (S0), 1 mL L-1  of water (S1) and 2 mL L -1  of water (S2);   and AMF dose as subplot consisted of three levels, namely: without AMF (M0), 5 g plant-1  (M1) and 10 g plant-1  (M2). therefore, there were 9 combinations of treatments and each treatment combination was repeated  three  times  to  obtain  27  experimental  units.  Each  variable  was  analyzed  by analysis of variance, then followed by Duncan's Multiple Range Test (UJBD) at 95% confidence level. The results of research indicated that the best interaction of   AMF   and organic  nutrient  treatment was 10 g AMF plant-1 (M2) and 2 mL L-1 (S2) of organic nutrients. This treatment combination can improve growth on variables: leaf area, leaf area index and yield index of the chili plants.  The best treatment for AMF independently was at 10 g plant-1 (M2) because it can promoted growth of plant height of the chili plants. The best treatment for organic matter independently was at 2 mL L-1(S2), because it can promoted growth of plant height of the chili plants. Keywords: FMA, organic nutrition, growth, chili
