### Melon Fruit Traits  
Table 3 showed the analysis of variance of fruit traits of melons grown under different _Azolla_ treatments. Fruit weight (0.54 **), fruit height (4.23 **), fruit perimeter (7.45 **), rind thickness (0.24 **), pulp thickness (1.19 *), fruit cavity (1.80 **), lightness (34.06 *), redness (10.53 *), yellowness (47.01 *), color appearance (2.21 *), color saturation (54.00 *), total soluble solid (10.59 **), were significantly different among the _Azolla_ treatments. However, there is a nonsignificant difference found in the pulp firmness (0.02 *), juice electrical conductivity (763,548 *s), and juice pH (0.03 *ns). Table 4 showed the mean comparison of fruit traits of melons grown under different _Azolla_ treatments. As compared to control treatments, the treatments of fermented and fresh _Azolla_ were not significantly different in the traits of fruit perimeter (15.36 \(\pm\) 0.85 and 14.43 \(\pm\) 0.84 cm), fruit height (15.79 \(\pm\) 0.81 and 15.21 \(\pm\) 0.86 cm), fruit weight (1.64 \(\pm\) 0.18 and 1.44 \(\pm\) 0.12 kg), pulp thickness (2.89 \(\pm\) 0.16 and 3.08 \(\pm\) 0.34 cm), fruit cavity (6.14 \(\pm\) 0.21 and 5.70 \(\pm\) 0.41 cm), and total soluble solid (11.26 \(\pm\) 0.94 and 11.53 \(\pm\) 1.55 *Brix). Whereas the fruits from the treatments of dried _Azolla_ were the lowest of those traits. The radar chart of melon fruit pulp is illustrated in Figure 2. The melon fruit pulp from control treatment shows the highest value of redness (\(a^{*}\); 9.26), yellowness (\(b^{*}\); 43.45), and color saturation (\(c^{*}\); 44.46), whereas it shows the lowest values of lightness (\(L^{*}\); 68.73) \begin{table}

Table 2: Analysis of variance of agronomic traits of melons grown under different _Azolla_ treatments. and color appearance (_Hue_; 36.24). The melon fruit pulp from dried _Azolla_ treatment shows the highest value of lightness (L\({}^{*}\); 73.88) and color appearance (_Hue_; 37.58), however, it was the lowest value of redness (\(a^{*}\): 5.90), yellowness (\(b^{*}\); 36.34), and color saturation (\(c^{*}\); 36.84). Several studies have reported that the nutrients supplied impacted fruit quality and pulp color. [PERSON] et al. [14] investigated the fish water with and without synthetic fertilizers for melon production.
