TEJADA VIZCARRA, Juan Carlos et al. Effect of hydrolysis of fish waste on the cultivation of spinach (Spinacia oleracea) in the city of Tacna - Peru. RIIARn [online]. 2025, vol.12, n.1, pp.57-63. ISSN 2409-1618.  https://doi.org/10.53287/mrmp1597fq18c.

The Negative environmental impacts are increasing due to various activities in different sectors, one of them in the agricultural sector is the application of different chemical inputs, causing environmental damage to the quality of soil, water and air, which is why different organic agricultural inputs have been developed to mitigate these impacts. Therefore, the objective of this research was to evaluate the hydrolysis of fish waste (head, viscera, bones and backbone) in the cultivation of spinach (Spinacia oleracea) in the city of Tacna. For which variables such as unit weight (g) and total yield (t ha-1) were analyzed; The spinach was planted in August 2023 and harvested in October of the same year, having a phenological period of 3 months; Four treatments were applied with different dosages of fish hydrolysis, where T1 consisted of 200 L ha-1, T2 with 400 L ha-1, T3 with 600 L ha-1 and T4 with 800 L ha-1. When applying an analysis of variance for the unit weight of the spinach, highly significant differences were evident between the treatments and blocks; however, in the analysis of variance of the total yield there were no significant differences between the treatments and blocks. Therefore, the highest average unit weight was obtained in treatment 4, reaching a value of 192.84 g; while the highest average total yield was evidenced in treatment 1, reaching a value of 3.403 t ha-1. It was concluded that the application of different doses of hydrolysis of fish waste influences the development of the spinach crop, which was demonstrated in the variables of total yield (t ha-1) and unit weight (g).

Keywords : hydrolysis; fish waste; spinach; total yield; unit weight.
