Abstract:
A field experiment was conducted during 2020-21 and 2021-22 on clay loam soil having low in available nitrogen (278.36 to 279.42 kg ha^-1), medium in available phosphorus (18.73 to 20.39 kg ha^-1) and high in available potassium status (328.40 to 332.72 kg ha^-1) with slightly alkaline in reaction at the Instructional Farm, Department of Agronomy, Rajasthan College of Agriculture, MPUAT, Udaipur during rabi season 2020-21 and 2021-22 with the objective to evaluate the response of malt barley to fertility levels and biofertilizers. The experiment was laid out in randomized block design (Factorial) with 15 treatment combinations comprised of three fertility levels i.e. application of 70 kg N+40 kg P₂O₅ +25 kg K₂O ha^-1, 60 kg N+30 kg P₂O₅ +20 kg K₂O ha^-1 and 50 kg N+25 kg P₂O₅ +15 kg K₂O ha^-1 with five liquid biofertilizers i.e. control, Azotobacter, PSB, KMB and Azotobacter + PSB + KMB. The result revealed that amongst fertility levels, application of 70 kg N+40 kg P₂O₅ +25 kg K₂O ha^-1 proved most effective in elevating nutrient status of grain and straw as compared to rest of the fertility levels. Among liquid biofertilizers, conjoint inoculation of seed with Azotobacter + PSB + KMB proved most effective in elevating nutritional status of grain and straw.
