“…However, few published studies are available on the influence of liming on kikuyugrass chemical composition other than the work of Awad, Edwards, and Milham (1976) and Awad and Edwards (1977) with an Australian Ultisol. Although increased forage Ca resulting from the application of Ca-containing soil amendments may slightly enhance the digestibility of some tropical grasses by altering cell-wall composition (Mathews, Miyasaka, and Tritschler 2004), the Ca-level solution-culture study of Marais, Figenschou, and De Figueirdo (1992) suggests that a similar effect is unlikely to be observed for kikuyugrass.…”

Kikuyugrass (Pennisetum clandestinum Hochst. ex Chiov.) is an active silicon (Si) accumulator, and Si can reduce the organic-matter digestibility of forage grasses. Calcium carbonate (crushed coral) applications to a low Si Maile silt loam soil (Acrudoxic Hydrudands) had no effect on the in vitro digestible organic matter (IVDOM) concentration of 3-week-old (4.5-leaf-per-tiller stage of development) 'Whittet' kikuyugrass regrowth, whereas calcium silicate (wollastonite) applied at the calcium equivalent of the calcium carbonate rates produced a curvilinear (crescent-shaped quadratic) IVDOM response. Whittet IVDOM decreased when grass Si concentration exceeded about 22 g kg 21 or when 0.5 M acetic acid-extractable soil Si exceeded about 230 mg kg 21 . Common and 'Hosaka' kikuyugrass regrowth on the Maile soil had less Si and greater IVDOM concentrations than those observed for high-Si Kohala (Humic Dystrustepts) and Waialua (Pachic Haplustolls) silty clay soils. Whittet had greater crude protein and IVDOM concentrations and lesser fiber concentrations than common.

“…ex Chiov (Kikuyo) es una pastura común en muchos ambientes y se asocia principalmente a los sistemas silvopastoriles en el altiplano cundiboyasense con diferentes especies arbóreas. Debido a su rápida tasa de crecimiento se utiliza para la alimentación de ganado, además es un pasto apetecible y altamente digerible, con alto valor proteico, bajo conte-nido de fibra y altas propiedades nutritivas (Marais et al, 1992), también se emplea en la recuperación de suelos degradados en ambientes fríos, para el control de la erosión, aplicados como cobertura del suelo. Numerosos reportes indican que P. clandestinum es tolerante al estrés abiótico como la salinidad, la sequía, el anegamiento y la acidez del suelo (Sidari et al, 2004).…”

Artícu lo cI ENtíF IcoM i c r o b i o l o g í a d e l s u e l o Effect of plant growth-promoting rhizobacteria (PGPR) associated to Pennisetum clandestinum in the altiplano cundiboyacense A B S T R A C TPennisetum clandestinum (kikuyo) is a common pasture in the altiplano cundiboyacense silvopastoral systems, which possesses high nutritional value. Therefore, studies to improve the production process in both economic and environmental terms are very important. The role of inoculation with plant growthpromoting bacteria was evaluated on the growth of kikuyu grass. The 4K and 5B strains were identified, through amplification and analysis of their 16S rDNA, as members of the Stenotrophomonas and Pseudomonas genera, respectively. They were characterized in vitro for their efficiency of biological nitrogen fixation, production of indole compounds, and phosphate solubilization. Four treatments were evaluated under greenhouse conditions. Furthermore, the biomass was evaluated at different stages of the plant (70, 100 and 130 days). The 4K strain demonstrated a root dry weight that increased by 50% at 70 and 100 days and the 5B strain showed a statistically significant behavior for plant and root dry weight with an increase of 50% at 130 days. The most important effect was presented after 100 d where treatments, TQ, TB1 and TB2, exceeded more 80% to absolute control in the fresh weight of the air. These results showed that inoculation with PGPR represents a biotechnological alternative to promote growth of P. clandestinum, as we observed relevant effects on biomass production 100 days after planting.
