Impact of farm-made liquid organic nutrients jevamirtham and fish amino acid on growth and nutritional status in different season of Abelmoschus esculentus—a self-sustainable field trial

In organic agriculture, jeevamirtham (J) and fish amino acids (FAA) (Liquid organic nutrient bioformulations—LONBFs) were used to improve the plant growth and soil fertility. The effect of J and FAA in combination on the growth, nutritional status, and yield of plant has not been scientifically evaluated. In this study, liquid organic preparations of J and FAA were prepared and applied to okra plants individually and in combination (J + FAA). The experimental fields were designed as T1—untreated control field, T2—chemical fertilizer treated field, T3—jeevamirtham-treated field, T4—fish amino acid-treated field, and T5—mixture of jeevamirtham and fish amino acid-treated field. Microbial population and growth parameters were significantly increased in the T3, T4, and T5 fields. Higher chlorophyll, carbohydrate, and protein contents and more fruits were observed in plants from the T3, T4, and T5 fields than in plants from T2 and T1. The most favorable results were recorded in the J+FAA-treated field (T5). Results showed that LONBFs enhanced the beneficial microbial flora and fauna, higher yields, and nutritional products compared with chemical fertilizer and untreated fields. Hence, this eco-friendly LONBF could be added as an integral component to reduce the impact of chemical fertilizer in modern agriculture practice.
