SARMIENTO-SARMIENTO, Guido Juan et al. Application of vermicompost and seaweed in the watermelon crop (Citrullus lanatus Thunb.) Var. Santa Amelia. Scientia Agropecuaria [online]. 2019, vol.10, n.3, pp.363-368. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2019.03.06.

The global trend of the consumption of harmless fruits from sustainable agricultural systems demands the need to look for alternatives to the use of agrochemicals. In this context, the research aimed to determine the effect of the application of vermicompost (HL) and seaweed cream (AM) on the yield and profitability of watermelon fruits var. Santa Amelia in San Camilo irrigation, Arequipa - Peru. Three levels of HL were studied: 4 t·ha^-1 (HL4); 8 t·ha^-1 (HL8); 12 t·ha^-1 (HL12); and two levels of AM: 2 l·ha^-1 (AM2) and 4 l·ha^-1 (AM4), from which 6 treatments emerge in experimental design of random complete blocks (DBCA), with factorial arrangement 3 x 2. HL was incorporated into the soil in full dose at 30 days from the planting of the plant in a localized manner; AM was applied via foliar to 30 and 60 days of sowing. The highest yield was achieved with HL8AM2 treatment (48,62 t·ha^-1), with an average weight of 9,2 kg·fruit^-1; however, the highest profitability of the crop was achieved with HL4AM2 (124%). No significant statistical differences were observed in the content of total soluble solids (SST) due to the effect of the treatments.
