Abstract:

Composite topsoil samples from 16 study sites were taken and then their physical as well as chemical attributes were determined at the National Soil Testing Center (NSTC). Moreover, plant attributes such as Leaf Length (LL), Leaf Biomass (LB), Fiber Length (FL) and Tensile Strength (TS) were measured. Data analysis was carried out using JMP5 (version 5.0) and SPSS (version 12.0) statistical softwares. The one way analysis of variance (ANOVA) for Leaf Length (LL), Leaf Biomass (LB), and Tensile Strength (TS) showed statistical significance with respect to the study sites ( p<0.0001). Furthermore, one way ANOVA for tensile strength (TS), Leaf Biomass (LB) and Leaf Length (LL) with respect to blocks found statistically significant at p<0.0001, p<0.001 and p<0.05 respectively. Nevertheless, one way ANOVA for Fiber Length (FL) appeared statistically insignificant (p>0.05) with respect of blocks. On the other hand, the one way ANOVA for both soil chemical and physical attributes with respect to blocks found statistically insignificant (p>0.05). The rainfall, sunshine, and temperature situations as well as the soil chemical and physical attributes being inline with the requirements of Agave species could be reasons for the unique growth and development of A. americana and A. sisalana crop plants in the study area.
