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 the 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 experimental
results revealed that malt barley crop took maximum days to attain heading, 50 % anthesis and physiological maturity when crop was fertilized with highest
fertility levels i.e. 70 kg N+40 kg P2O5 +25 kg K2O ha-1 as compared to application of 60 kg N+30 kg P2O5 +20 kg K2O ha-1 and 50 kg N+25 kg P2O5 +15 kg
K2O ha-1. Among different liquid biofertilizers, Seed inoculation with Azotobacter + PSB + KMB recorded maximum days taken to heading, 50% anthesis and
physiological maturity over single inoculation of Azotobacter, PSB and KMB. The study showed the result that combined application of 70 kg N+40 kg P2O5
+25 kg K2O ha-1 + liquid biofertilizers Azotobacter + PSB + KMB extended the growth duration of crop and helps to increase productivity of malt barley crop.
