An experiment on INM effect on growth, yield, quality, nutrient uptake, and economics of garden pea (Pisum sativum var. hortense L.), cv. Arkel, was carried out in the rabi season of 2025-26 at the Research Farm of SAM Global University, Raisen, MP. The experiment was based on Randomized Block Design with 10 treatments and 3 replications. The treatments comprised various combinations of RDF, FYM, Rhizobium, PSB, and foliar NPK spray. No significant differences in plant population were observed due to INM treatments, suggesting that the crops were established uniformly. On the other hand, plant height, days to 50% flowering, yield characteristics, yield, nutrient uptake, protein content and economics were significantly affected by the treatment combinations. The use of 75% RDF+ 2.5 t/ha FYM (Treatment No.4) resulted in the highest value in plant height (58.17 cm), seeds/pod (8.20), pods/plant (32.98), seed index (14.33 g), biological yield (6928 kg/ha), grain yield (2286 kg/ha), harvest index (33.0%), protein content (20.77%) and protein yield (475.2 kg/ha). Similarly, the treatment combination T4 also showed maximum values in nitrogen, phosphorus and potassium uptake along with the highest net returns (Rs. 90957/ha) having benefit cost ratio 3.25. The results suggest that substitution of chemical fertilizer partially with FYM is highly beneficial in terms of increasing productivity and grain quality along with its economic profitability of garden peas.
