Rice (Oryza sativa L.) is an important cash
crop in Honduras. The availability of inexpensive irrigation in the study
area (Flores, La Villa de San Antonio, Comayagua) encourages rice farmers to
neglect prescribed methods of soil and water conservation, such land leveling,
puddling, and soil bunds. This study looked at the effect of failure to
mitigate water loss on sloping fields. Soil moisture (Volumetric Water Content)
was measured using a soil moisture probe after the termination of the first
irrigation within the tillering/vegetative, panicle emergence/flowering,
post-flowering/pre-maturation and maturation stages. Yield data were obtained by harvesting on 1 m2 plots in each soil moisture testing site. Data analyses looked at the relationship between yield and slope, soil
moisture, farmers, and toposequential position along transects. Toposequential
position influenced yields more than slope and soil moisture was not a significant
predictor of yields. Irrigation politics, high water inputs, and land tenure
were proposed as the major reasons for this result.
We assessed the spatial distribution of Copernicia alba Morong. In the study area, a lowland palm savanna floodplain, C. alba is the only overstory species. We hypothesized C. alba would be randomly distributed within natural stands. Palms were tallied in six randomly located 0.25 haplots and analyzed using a first-order, Ripley’s K function to assess the distribution of juvenile, adult, and total palm populations. While the total population had either aggregated or random distributions, when analyzing juvenile and adult population separately, we found juveniles were consistently more aggregated than the adults.
