Abstract

The research aims to determine the main types of pests and the intensity of their damage to chili plants with different cultivation systems. This research was conducted in Konda Satu Village, Konda District, South Konawe Regency. This study consisted of 3 treatments with 6 replications, so there were 18 experimental units. Observational data were analyzed using analysis of variance (ANOVA) and if the results showed significant differences then it was continued with the Least Significant Difference Test (LSD) at the 95% confidence level to find out the best treatment by testing the differences between all treatments. Then test further LSD0.05. This study used three cultivation systems as treatments, namely the Conventional Cultivation System (Without Application of Biofresh Fertilizer + 100% Inorganic recommended dose + Use of Plastic Mulch), Semi-Organic Cultivation System (Application of Biofresh Fertilizer 50% recommended dose + 50% Inorganic of recommended dose + Application Phymar C Botanical Pesticides + Use of Plastic Mulch), and Organic Cultivation Systems (100% recommended dosage of Biofresh Fertilizer Application + Phymar C Botanical Pesticide Application + Organic Mulch). The results showed that the main pests that attack chili plants are armyworm pests (Spodoptera litura), fruit fly pests (Bactrocera sp.) and Aphids pests (Aphididae). The lowest damage intensity of armyworm pests was in the organic cultivation system of 18.08%, the lowest intensity of fruit fly pest attacks was in the semi-organic cultivation system of 31.81%, the lowest intensity of attack by aphids was in the semi-organic cultivation system of 12.59%.

Abstract

The  research was  conducted to  test  the  potency  of  several local  maize genotypes (landraces) of Southeast Sulawesi and to find the genotypes that were tolerant to less water conditions. The research was performed in  a  plastic house at  the  experimental farm of Agriculture Faculty, University of Halu Oleo.  The research was arranged in a Randomized Complete Design (RCD) with 2 treatment factors. The first factor was water availability level (A), consisted of 3 (three) levels (A0, A1 dan A2), and the second factor was maize genotype, consisted of 9 local maize and 1 national variety (Arjuna).  Research results showed that the less water conditions (A1 and A2) had negative effects on maize vegetative variables (plant height, plant diameter, leaf number and length of leaf tip).  On the other hand, the genotype treatment had significant effect on plant height, plant diameter, and length of leaf tip. Genotipe G7 dan G6 had the highest plant height, while G1 had the biggest plant diameter. Keywords: less water condition, local maize genotype, vegetative stage

Abstract

Ginger (Zingiber officinale Rosc.) is one of the spices and medicinal plants which has many benefits and usefulness. Currently ginger production in Indonesia is still very low, du e to limited sources of genes possessed by plant breeders (narrow genetic stock), therefore it is  necessary to  obtain new  genetic diversity. The  purpose of  this  study was  to  conduct exploration activities to collect local ginger germplasm in Southeast Sulawesi to get information in the form of (a) genetic diversity of accessions, (b) determination that can be used to identify germplasm genetic diversity of ginger of Southeast Sulawesi, (c) description of the collected ginger types, for the benefit of ginger crop improvement through breeding programs. This study began with exploration activities, then planting accessions for collection and conservation which will be utilized in various ginger breeding programs. The results of exploration obtained as many as 18 accessions from Kendari, Konawe, Bombana, Muna and Buton regencies. Results of the collection of some areas of Southeast Sulawesi showed that ginger genetic diversity was quite high, seen from the morphological appearances of the rhizome.  Based on the size, shape and color of the rhizome, the ginger accessions of Southeast Sulawesi can be classified into three major groups, i.e. large white/yellow ginger, small white/yellow ginger, and red ginger. White ginger was large and more attractive than red ginger, but less spicy aroma due to its low essential oil content, and less disease resistant, but high productivity. Keywords: ginger, Zingiber officinale, genetic diversity

Abstract

Rhizobacteria have been used for plant growth enhancement. The research was aimed on  finding  the  best  method  of  preplant  seed  treatment through  seed  invigoration plus rhizobacteria as biofertilizer to increase physiological quality of preplant sorghum   seed. The research was undertaken in Agronomy Laboratory, Agriculture Faculty, Haluoleo University, Kendari Southeast Sulawesi.    Research results showed that seed bio- matriconditioning with rhizobacteria was effective in enhancing seed quality of sorghum. The most effective treatment was the integration of seed matriconditioning using rice hull charcoal  or  ‘serbuk  bata  merah’  with  rhizobacteria  Pseudomonas  fluorescens  PG01  or Bacillus spp.CKD061. The seed treatment increased seedling growth by 120% compared to untreated seed. Based on this experiment, rhizobacteria P.fluorescens PG01 or Bacillus CKD061 integrated with   rice hull charcoal or ‘serbuk bata merah’ seed matriconditioning can be used as biological agents in improving seed quality of sorghum. Key words:   bio-matriconditioning, rhizobacteria, seed quality, sorghum

Abstract

ABSTRACT The research was aimed to analysis the integration of seed invigoration with rhizobacteria to improve the growth of Numbu and Kawali varieties of sorghum (Sorghumbicolor L.). The experiment design was a randomized block design arranged in Split-plot pattern. The main factor was sorghum varieties which consisted of 2 varieties ie. Numbu and Kawali. The sub plot was seed biomatriconditioning integrated with rhizobacteria treatments which consisted of 5 treatments, namely: control, seed biomatriconditioning with Bacillus sp. CKD061 + rice hulls charcoal, seed biomatriconditioning with Bacillus sp. CKD061 + red brick powder, seed biomatriconditioning with Pseudomonas fluorescens PG01 + rice hulls charcoal, and seed biomatriconditioning with P. fluorescens PG01 + red brick powder. Every treatment was replicated 3 times, therefore, overall there were 30 experimental units. Data obtained were analized using analysis of variance and followed by Duncan’s Multiple Range Test. The result of growth analysis showed that the interaction of both factors significantly influenced the leaf area index, plant growth rate, and net assimilation rate. In both varieties, seed biomatriconditioning with Bacillus sp. CKD061 or P. fluorescens PG01 using red brick powder or rice hulls charcoal were effective in increasing leaf area index, plant growth rate, and net assimilation rate of sorghum compared with untreated treatment. Keywords: biomatriconditioning, rhizobacteria, sorghum
