Abstract: The study “Effect of Fly Ash in Combination with farm yard manure and Vermicompost on nutrient content and uptake in rice” was conducted at Krishi Vigyan Kendra, Janjgir-Champa, Chhattisgarh during kharif 2022 and 2023. Using a Randomized Block Design with 16 treatments across 3 replications, we evaluated various combinations of fly ash, farm yard manure, and vermicompost for their impact on nutrient uptake and nutrient content in rice. The soil was clay loam, low in nitrogen and phosphorus, with adequate potassium and slightly acidic pH. The highest nutrient uptake was observed with Fly Ash @ 30 t/ha + 100% RDN + Vermicompost @ 2.5 t/ha (T₁₃), showing superior results for nitrogen, phosphorus, potassium, and micronutrients compared to other treatments, with the lowest uptake under Fly Ash @ 20 t/ha (T₆).
