Abstract

The experiment was carried out to characterize the ability of rhizobacteria isolated from the rhizosphere of healthy lowland rice in dissolving phosphate or fixing nitrogen.  The research was conducted from February to June 2011 at Agronomy Laboratory, Agriculture Faculty, Halu Oleo University. The experiment was arranged based on descriptive methods. Overall, the number of isolates characterized were 40 isolates.  The results of the isolate characterization were documentated with specific indicators (eg. the ability to dissolve phosphate in the form of halo/clear zone). The research indicated that most of these isolates had the ability to dissolve phosphate and fix nitrogen.  Isolates PKNW 6, PKMN 7,  PKNS 3, PKNS 9 and PKNW 4 showed better ability in dissolving phosphate and fixing nitrogen than other isolates evaluated. Further studies are still needed for the development of the potential isolates as biological agensts or biofertilizer.

Abstract

The objective of this research was to evaluate the effect of seed invigoration on improving seed viability and vigor, and to overcome problems of postharvest physiological dormancy of upland rice seed. The research was conducted from February to June 2011 at Agrotechnology Laboratory, Faculty of Agriculture, Halu Oleo University. The experiment used randomized complete design which consisted of 13 treatments, i.e control (G0), Hidration-Dehidration (G1), Matriconditioning using ground brick (G2), Matriconditioning using ground burned-rice husk (G3), Bacillus CKD061 (G4), P. fluorescens PG01 (G5), Serratia CMN175 (G6), Biomatriconditioning using ground brick + Bacillus CKD061 (G7), Biomatriconditioning using ground brick + P. fluorescens PG01 (G8), Biomatriconditioning using ground brick + Serratia CMN175 (G9), Biomatriconditioning using ground burned-rice husk + Bacillus CKD061 (G10), Biomatriconditioning using ground burned-rice husk + P. fluorescens PG01 (G11), Biomatriconditioning using ground burned-rice husk + Serratia CMN175 (G12). Each treatment was replicated three times, therefore, overall there were 36 experimental units. Data obtained were analyzed using analysis of variance and followed with Duncan’s Multiple Range Test. The research results showed that bio-invigoration treatments integrated with rhizobacteria were effective to overcome the problems of postharvest physiological dormancy when local upland rice seeds were harvested. In addition, this treatment was also able to increase viability and vigour of the seed. Among treatments tested, the use of Bacillus sp. CKD061 or P. fluorescens PG01, either independently or integrated with matriconditioning using ground brick or ground burned- rice husk was more effective in improving viability and vigour of local upland rice seed compared to other treatments.

Abstract

The research aimed to know the efectifity of cover crop applied with rhizobacteria to influence chemical characteristic of  soil of  ex-nickel mine. This research was conducted since May to August 2012 at experimental farm and Agrotechnology Laboratory of Faculty of Agriculture of  Haluoleo  University. Soil  analysis  was  carried  out  been  in  Soil  Research Institute Bogor. The experiment was designed in a randomized block design, in a factorial pattern. The first factor was application of rhizobacteria consisted of 2 levels : R0 (without application of rhizobacteria) and R1 (with application of rhizobacteria). The second factor was cover crop with 4 levels, namely : C1  (Centrosema pubescens Benth.), C2  (Calopogonium mucunoides), C3  (Crotalaria sp.) and C4  (Amaranthus spinosus L.), resulted in 8 treatment combination. Each treatment was repeated 3 times, resulted in 24 experimental units. The experimental data were  analyzed using analysis of variance and then followed by Least Significant Differences Test. Soil analysis data were analyzed descriptively. The research results showed that the application of rhizobacteria at Crotalaria sp. (C3) gave a significant effect on crop height and number of leaf branch. Besides, application of cover crop and rhizobacteria at ex-nickel mine increased soil chemical characteristic C organic, N total, P2O5, HCl 25% and K-ddKey words :   Rhizobacteria, cover crop, soil chemical, nickel mining
