Abstract
A randomized block design experiment with 11 treatments and 3 replications was conducted during Kharif 2020 to investigate the impact of liquid biofertilizers on finger millet (Eleusine coracana L.) growth and yield. The study used RAU-8 variety, sown on July 28, 2020, with a recommended fertilizer dose of 40:20:20 NPK kg/ha. Results showed that combining 100% RDF with liquid biofertilizer seed treatment and soil application significantly enhanced soil nutrient availability, dehydrogenase activity, and crop productivity, comparable to RDF alone. that integrating 100% recommended dose of fertilizers (RDF) with liquid biofertilizers significantly enhanced soil nutrient availability, with notable increases in nitrogen (185.25 kg/ha), phosphorus (19.21 kg/ha), and potassium (132.78 kg/ha) levels under the application of 100% recommended dose of fertilizers (RDF) in conjunction with liquid biofertilizer treatment, comprising seed inoculation (5 ml/kg seed) and subsequent soil application (2.5 L mixed with 500 kg farmyard manure applied in furrows), which was found to be at par with treatment T10- RDF (40:20:20, N:P:K Kg ha -1) and lower available nitrogen (121.52 kg ha -1 kgha-1), phosphorus (10.40 kg ha -1) and potassium (84.78 kg ha -1 ) in soil were estimated with T11 -(control) has observed that the greatest post-harvest availability of total N, P2O5, and K2O from finger millet has demonstrated a noticeably higher nutritional availability.
