Currently, biostimulants obtained from protein hydrolysates are considered essential agronomic tools to promote sustainable agriculture without the use of chemical fertilizers. This study aimed to investigate the effectiveness of a biostimulant obtained from slaughterhouse sludge via enzymatic hydrolysis processes on green pepper crops in a greenhouse. The biostimulant was administered through both root and foliar applications at two different doses (0.7 and 1.4 g L−1), with a total of four applications made over the 140-day experimental period. Throughout the crop growth period, various parameters were assessed, including plant height, the number of flowers and fruits, macro- and micronutrient content, and photosynthetic pigments in the leaves. Additionally, the nutritional content and vitamin C levels in the harvested fruits were determined. The results obtained indicated higher values of these parameters in the pepper plants when the biostimulant was applied at a higher dose and through root application. These higher values are likely a consequence of the increased plant absorption of the low-molecular-weight amino acids and nutrients derived from the biostimulant. |
