The potential of bamboo as a plant for soil and water conservation can be identified by the morphological character. The quality of bamboo can be shown from the morphological character. Bamboo is a plant that is difficult to propagate generatively, while there is a paucity information on the vegetative propagation of bamboo species especially genus of Gigantochloa and Schizostachyum. The aims of this research is to characterize morphology of bamboo, studies of bamboo propagation with vegetative method andmeasure the potential of bamboo as a plant for soil and water conservation. 4 species of bamboo namely Gigantochloa atroviolaceae Widjaja, G. robusta Kurz., G. luteostriata Widjaja and Schizostachyum zollingeri Steud.are used in this study. The result ofmorphology characterization show that four species of bamboo have unique morphological characteristics from reed midribs, reed height, diameter, leaves and roots. The results of vegetative propagation of bamboo using different growing media show that thecompost + soil (1: 1) is the best for bamboo growth. Soil media can also be used as an alternative media for vegetative propagation. Sand media gives the lowest growth. G. atroviolaceae and G. robusta are species of bamboo that suitable for soil and waterconservation. Both species of bamboo are characterized by strong reed, dense growth and canopy, good quality of litter, and a strong root system that supports to soil and water conservation.

Land degradation is a global negative environmental process that causes the decline in the productivity of land resources’ capacity to perform their functions. Though soil and water conservation (SWC) technologies have been adopted in Geshy subcatchment, their effects on soil quality were limitedly studied. The study was conducted to evaluate the effects SWC measures on soil quality indicators in Geshy subcatchment, Gojeb River Catchment, Ethiopia. A total of 54 soil samples (two treatments–farmlands with and without SWC measures ∗ three slope classes ∗ three terrace positions ∗ three replications) were collected at a depth of 20 cm. Statistical differences in soil quality indicators were analyzed using multivariate analysis of variance (ANOVA) following the general linear model procedure of SPSS Version 20.0 for Windows. Means that exhibited significant differences were compared using Tukey’s honest significance difference at 5% probability level. The studied soils are characterized by low bulk density, slightly acidic with clay and clay loam texture. The results revealed that farmlands with SWC measures had significantly improved soil physical (silt and clay fractions, and volumetric soil water content (VSWC)) and chemical (pH, SOC, TN, C : N ratio, and Av. phosphorus) quality indicators as compared with farmlands without SWC measures. The significantly higher VSWC, clay, SOC, TN, C : N ratio, and Av. P at the bottom slope classes and terrace positions could be attributed to the erosion reduction and deposition effects of SWC measures. Generally, the status of the studied soils is low in SOC contents, TN, C : N ratio, and Av. P (deficient). Thus, integral use of both physical and biological SWC options and agronomic interventions would have paramount importance in improving soil quality for better agricultural production and productivity.
