Abstract

In order to improve soil fertility and plant nutrients, agricultural growth will optimize agricultural waste resources, such as shrimp waste. More than half of the yearly global output weight is made up of shrimp waste. Pots experiment was conducted to assess the impact of these wastes on faba bean production by incorporating phosphorene (phosphorus-dissolving bacteria) and using them as a total or partial substitute for mineral fertilization. The design used was completely randomized blocks (CRD), consisting of nine treatments: control, NPK, Phosphorene, Shrimp shell powder, Shrimp + ½ NPK, Phosphorene + ½ NPK, Shrimp + Phosphorene, Shrimp + Phosphorene + ½ NPK, and Shrimp + Phosphorene + NPK. Results showed that adding shrimp shells with phosphorene and half of the recommended dose of the chemical fertilizer for beans recorded the highest germination rate, germination velocity index (GVI), plant weight and length, and root weight. The addition of phosphorene improved the nutritional state of the plant and soil by increasing phosphorus and potassium levels. Nitrogen recorded the highest value with the addition of shrimp shells with phosphorene. Shrimp shells and phosphorene are eco-friendly fertilizers, emphasizing their combined benefits for soil health and plant growth. Therefore, reducing chemical additives by adding shrimp shells and phosphorene is recommended.
