A field experiment was conducted in Research Field, Department of Horticulture, Naini Agriculture Institute, SHUATS, Prayagraj; during 2019-2020 to study the effect of different concentration of Arka microbial consortium (AMC) on growth, yield and quality of lettuce (Lactuca sativa) cv. Grand rapid under poly house in Prayagraj agro-climatic condition. Arka microbial consortium with different concentrations was tried. The experiment was laid out in randomized block design having 11 treatments replicated thrice. The result showed that 10g Arka microbial consortium + 75% recommended dose of nitrogen, phosphorous and 100% potassium gave the minimum days to germination (4.07) followed by (4.43) 8g Arka microbial consortium + 75% recommended dose of nitrogen, phosphorous and 100% potassium. Maximum days to germination (6.38) were recorded in control treatment. Maximum plant height (13.74 cm) was recorded in 10g Arka microbial consortium + 75% recommended dose of nitrogen, phosphorous and 100% potassium and minimum (8.78 cm) was observed in control. Minimum days to first harvest (29.63) and last harvest (38.45), maximum number of leaves/plant (10.58) and minimum harvesting duration (5.57) was recorded in 10g Arka microbial consortium + 75% recommended dose of nitrogen, phosphorous and 100% potassium. The yield parameters- average weight of the plant (164.30g), average weight of trimmed head (133.54g), yield/plot (4.80kg), yield/ha (10.88t) and quality parameters- Total soluble solids (5.41 °Brix) and Vitamin C (8.66 mg/100g) and the overall acceptability in Organoleptic test was also recorded best in 10g Arka microbial consortium + 75% recommended dose of nitrogen, phosphorous and 100% potassium. The maximum gross return, net return and benefit cost ratio was recorded in 10g arka microbial consortium + 75% recommended dose of nitrogen, phosphorous and 100% potassium.
