Exploration carried out in the filosphere area (leaves) and rhizosphere area (roots) in upland rice plants to get the type of microbes that have potential that can be utilized as biological fertilizer sources, such as N2 fastening microbes, plant growth microbes or phosphate solvent microbial as well as those acting as natural enemies. The research was conducted by location survey method. Determination of location is done by purposive sampling, which is the location of upland rice cultivated by farmers in Kulawi District. The results showed that 10 isolates were isolated from epiphytic and endophytic microbes and endophytes. Morphological tests showed differences in color, shape, elevation, edge, texture and size and the coloring test showed that the bacteria had Coccus cell forms, Bacill, Diplococcus and Semi-Bacillus.

ysoxylum  mollissimum is a commodity that is widely used as carpentry wood and furniture in Bengkulu. Rastrococcus sp. is one of the pests of D. mollissimum. The purpose of this study was to evaluate the attack of Rastrococcus sp. on saplings, poles and trees D. mollissimum in the campus forest of Bengkulu University. The study was conducted with a purposive sampling survey method. The observational variables were symptoms and the rate of attack of Rastrococcus sp. at various stages of growth, the host range, and the identification of natural enemies of Rastrococcus sp. The results showed that Rastrococcus sp. was able to attack D. mollissimum at all growing stages, namely sapling, pole and tree. The highest number of Rastrococcus sp. population was observed in the pole phase (35.4 ± 6.46 individuals), then the tree phase (34.9 ± 20.38 individuals), and saplings (26.3 ± 5.12 individuals). The Rastrococcus sp. was commonly found in the lower leaves. Scymnus sp. (Coleoptera: Coccinellidae) and Acarina (mites) were found as predator of the mealybug. This information is expected to be a reference in developing control strategies of Rastrococcus sp. especially on D. mollissimum.

ABSTRACT: A major problem affecting some upland rice cultivars is the increase in plant size when subjected to high doses of nitrogen fertilizer, leading to high levels of lodging. A method to reduce the height of upland rice, and therefore lodging, would be to use plant growth regulators. However, little information exists on the effect of these regulators on plant physiological processes. Therefore, the objective of this study was to evaluate the influence of trinexapac-ethyl application in upland rice via analysis of growth and gas exchange. The experiment was carried out under greenhouse conditions using the BRS Primavera cultivar. A completely randomized design with eight replications was used. Treatments were carried out with and without the application of the plant growth regulator, and plants were subject to two-stage assessments in which physiological and gas-exchange indices were measured. The use of trinexapac-ethyl improved the growth of rice plants from the flowering to the physiological maturity stage, resulting in higher values of leaf area ratio, specific leaf area, and leaf matter ratio in treated plants. At the same time, it provided smaller reduction in net CO2 assimilation at the physiological maturity stage. Thus, net/apparent assimilation rate did not change after the application of growth regulator, but relative growth rate decreased in these treated plants. These results indicate the occurrence of self-shading in rice plants induced by what might be a supra-optimum trinexapac-ethyl concentration.
