The results were as follows: First, diurnal changes in PR revealed that the maximum values of PR in sago palms were in the range of 25-27 mg CO2 dm-2 h-1 in a palm after trunk formation that was grown in Kendari, values which were much higher than those recorded at younger stages in previous reports (8-15 mgCO2 dm-2 h-1) . The PR values in palms prior to trunk formation that were grown in Bogor were in the range of 16-18 mg CO2 dm-2 h-1. Similar values were observed for the average PR of some folk varieties grown in Jayapura (17.2 mg CO2 dm-2 h-1). Second, the PR was saturated at the light intensity of about 500 ƒÊE m-2 s-1, suggesting that low light saturation plays an important role in maintaining the levels of CO2 fixation required for a high starch yield under the low light conditions caused by the canopy cover. Third, the PR was closely related to the mesophyll conductance (Gm), an indicator of CO2 fixation ability: the decrease in the PR values of the lower leaves was due to the decrease in Gm. However, the lower PR values recorded in Bogor than those in Kendari were associated with stomatal conductance (Gs), rather than with Gm.

The research was conducted at the Agronomy Laboratory, Faculty of Agriculture, Halu Oleo University. Research was arranged in a completely randomized design (CRD) consisting of 24 isolates. The isolates were evaluated their ability to improve the viability and vigor of upland rice seeds. Before tested, upland rice seeds were treated with rhizobacterium isolates of Bacillus spp., and Pseudomonas fluorescens and germinated using standard germination procedures. Germination was recorded daily until 7 days. On the same time all isolates were evaluated for their ability to produce IAA and dissolve phosphate. Results of the experiments showed that seed treatments using rhizobacteria significantly increased viability and vigor of the treated upland rice seeds (percentage of increases as compared to untreated seeds in seed germination u...

The content of anthocyanin will determine the quality of red rice. Upland red rice can be planted as an intercrop to maximize land use on estate crops or forestry. Planting rice as an intercrop will face stress due to a lack of light, and will decrease production capacity, but the anthocyanin content will increase. This research conducted in Agrotechnology Field Experiment, Faculty of Agriculture, Halu Oleo University, arrange in a split design. The different of shade placed as main plot of as follows; N0 = without shading, N1 = 25% shading level, N2 = 50% shading level, and N3 = 75% shading level.

The study conducted in the Laboratory of Agronomy, Agriculture Faculty, Halu Oleo University. Research arranged in a completely randomized design (CRD) consisting of 20 rhizobacterial isolates. Analyses of data using analysis of variance to test viability and seed vigor, while the ability of bacteria to produce IAA growth hormones, phosphate solubilization, and nitrogen fixation were analyzed qualitatively. The results showed that the inoculation of the rhizobacterial isolate could increase the vigor and viability of shallot seeds. Rhizobacteria's ability to increase seed viability and vigor both directly and indirectly relates to its ability to produce IAA growth hormone, phosphate solubilization and nitrogen fixing. Of the 20 rhizobacterial isolates, there were 19 isolates that we're able to fix nitrogen, 13 isolates which could solubiliz...

An experiment was conducted to evaluate different upland rice lines for their growth and yield characteristics. Four rice lines including GS44-2 (V1), GS16-2 (V2), GS44-1 (V3), and GS16-1 (V4) were evaluated in a randomized complete block design (RCBD). The variables observed were vegetative character and generative character including grain yield. Data on various growth and yield characteristics revealed there were growth and yield characteristics different among breeding lines of local upland rice. Plant height at age 84 DAP, GS16-2 line was the tallest (92.71 cm) and GS44-1 line the shortest one (70.07 cm). Breeding line of GS16-2 produced higher leaf area (61.0 cm2), panicle length (30.94 cm), grain number per panicle (230.60), and filled grain number (190.25). The lowest unfilled grain percentage (26.67 %) was also recorded from GS16-2 lines. The highest number of tillers, number of productive tillers, grain dry weight, and grain yield were obtained from GS44-2 lines. Further, grain yield component such as grain dry weight and 1000 grain weight recorded positive and significant correlation with number of productive tillers per hill.

Banana plants have many benefits for human needs so that they have high economic value. Bananas can play a role as food substitutes containing calories, protein, carbohydrates, fats, vitamins, and minerals that are needed by the human body. The potential development of bananas is quite significant because it has broad adaptability to various agro-climate zones and has excellent potential for commercial growth as an export commodity. The market potential abroad is enormous and continues to increase. The domestic market's potential also increased due to rising levels of income and quality of life. There are many obstacles to increasing domestic banana production. Besides, processed banana products have not optimally produced as a source of livelihood and community income.

One of the efforts is to develop upland rice by utilizing the dry land with organic fertilizer application. The research was conducted in North Buton using split plot design. The main plot was the treatment of manure dosage consisting of 4 levels of treatment and the second factor of local upland rice cultivars as a subplot consisting of 22 cultivars. Production characters were observed and assessments are panicle length, grain number, number of grain content, wet grain weight, dried grain weight, grain weight per culm, and grain yield (t ha-1). The results showed that the yield potency of local upland rice cultivar in North Buton ranged from 3.11- 4.97 t ha-1 and the treatment of organic fertilizer can increase the yield components of upland rice.
