Abstract
The study takes place at upper Mutale valley
and Madimbo corridor Irrigated Smallholder Agricultural production area. The
purpose of the study was to Outline Perspective of Irrigated Smallholder
Agricultural Enterprises in Vhembe District through Correlation for Demography
and Livelihoods in Association with the Cultivation of Sweet Potatoes as
Selected Field Crop. Chi-square test was used as descriptive analysis method
through application of Fischer Exact test. The Fischer Exact tests were
employed to test demography (gender, age, education, and income) in winter and
summer production season of Irrigated smallholder agricultural enterprises and
their association with the cultivation of selected field crop (i.e. Sweet
potatoes). The A Correlation for Demography and Livelihoods in Association with
the Cultivation of Sweet Potatoes as Selected Field Crop were determined and
associated. The results show that, gender is statistically significant, the
effect size showed a weak association (Cohen, 1988), [6] as measured
by the Phi measure of effect size, φ = 0.173, p = 0.003 in winter and φ =
0.095, p = 0.103 in summer. In Age, the result not being statistically
significant, the effect size showed a weak association, as measured by the Phi
measure of effect size, φ = 0.032, p = 0.863 in winter, while φ = 0.047, p =
0.727 in summer. As far as Education is concern, the result not being
statistically significant, the effect size showed a weak association, as
measured by the Phi measure of effect size, φ = 0.127, p = 0.197 in winter
production season and φ = 0.091, p = 0.492 in summer. In income, the result not
being statistically significant, the effect size showed a weak association, as
measured by the Phi measure of effect size, φ = 0.012, p = 0.841 in winter and
φ = 0.017, p = 0.774. In conclusion, the study has an impacts of the
demographic and livelihoods in correlation with cultivation of sweet potato as
a selected field crop. It should be noted that a Bonferroni correction was made
due to multiple comparisons with the same dependent variable (cultivating Sweet
potato), this correction decreases the possibility of making a type I error.
Therefore, the significant value of 0.05 was adjusted to 0.013 (0.05/4). This
level of significance was too steep for the effects of the demographic traits
to be significance.
