*2.2.3 Analysis of results in relation to the concentration of copper in fruits (mg/kg)*

Ho: There are no differences in Cu between sampling groups.

H1: There are differences in Cu between sampling groups.

In the ANOVA, it is observed that the significance value is 0.371, a result that is obtained from comparing selected groups A, B, and C, respectively, in accordance with the heavy metal of copper according to intensity of use of agrochemicals. Said value is greater than the significance of α = 0.05; therefore, the statistical decision in this regard is to accept the null hypothesis; consequently, the alternative hypothesis is rejected, concluding that there is sufficient evidence to affirm that there are no significant differences in copper concentration in fruits at different intensity of application of agrochemicals with a confidence level of 95% (see **Table 3**).

### *2.2.4 Analysis of results in relation to the content of arsenic and lead in the soil (mg/kg)*

Ho: There are no differences in As and Pb between sampling groups.

H1: There are differences in As and Pb between sampling groups.

In the ANOVA, the significance values are of 0.863 (As) and 0.579 (Pb), results obtained from comparing selected groups A, B, and C, respectively, according to the heavy metal content of arsenic and lead in the soil from the fields of granadilla fruit production (*P. ligularis*) according to intensity of use of agrochemicals. These values are greater than the significance of α = 0.05; therefore the statistical decision in this regard is to accept the null hypothesis; consequently, the alternative hypothesis is rejected. In this way, it is concluded that there is sufficient evidence to affirm that there are no significant differences in the content of arsenic and lead in the soil samples at different intensity of application of agrochemicals at a confidence level of 95% (see **Table 4**).

#### *2.2.5 Analysis of results in relation to the mercury content in the soil (mg/kg)*

Ho: There are no differences in Hg between sampling groups.

H1: There are differences in Hg between sampling groups.

From the ANOVA analysis, the significance value is 0.012, whose result has been obtained after comparing between selected groups A, B, and C, respectively, in accordance with the heavy metal content of mercury in the soil from the granadilla fruit production fields (*P. ligularis*) according to intensity of use of agrochemicals. As can be seen, such value is less than the significance of α = 0.05; therefore the statistical decision in this regard is to reject the null hypothesis; consequently, the alternative hypothesis is accepted. In this way, it is concluded that there is sufficient evidence to affirm that there are significant differences in mercury content in the soil samples at different intensity of application of agrochemicals at a confidence level of 95% (see **Table 5**).

### *2.2.6 Analysis of results in relation to the content of cadmium in the soil (mg/kg)*

Ho: There are no differences in Cd between sampling groups.

H1: There are differences in Cd between sampling groups.

From the ANOVA analysis in **Table 6**, it is observed that the significance value is 0.331, a result obtained from comparing selected groups A, B, and C, respectively, in accordance with the heavy metal content of cadmium in the soil from fruit production fields granadilla (*P. ligularis*) according to intensity of use of agrochemicals. Said value is greater than the significance of α = 0.05; therefore the statistical decision in this regard is to accept the null hypothesis; consequently, the alternative hypothesis is rejected, concluding that there is sufficient evidence to affirm that there are no
