Abstract:
The field experiment was conducted at crop research farm during Rabi season 2021-2022, Department of Agronomy, SHUATS, Prayagraj (UP), to adjudge the influence of bio- fertilizer and seaweed extract on yield and economics of wheat. The experiment was conducted in Randomized Block Design consisting of 9 treatments combinations with 3 replications and was laid out with the different treatments allocated randomly in each replication viz., seed inoculation with Azotobacter (ASI) 20g/kg seed and 0% application of seaweed extract (SWE) (T₁), (ASI) 20g/kg seed and 5% application of (SWE) (T₂), (ASI) 20g/kg seed and 7.5% (SWE) (T₃), seed inoculation with phosphorus solubilizing bacteria (PSB) 20g/kg seed and 0% (SWE) (T₄), seed inoculation with PSB 20g/kg seed and 5% application of (SWE) (T₅), seed inoculation with PSB 20g/kg seed and 7.5% application of (SWE) (T₆), seed inoculation with both Azotobacter and PSB 10+10 g/kg seed and foliar application of 0% (SWE) (T₇), seed inoculation with both Azotobacter and PSB 10+10 g/kg seed and foliar application of 5% (SWE) (T₈), seed inoculation with both Azotobacter and PSB 10+10 g/kg seed and foliar application of 7.5% (SWE) (T₉). The results showed that seed inoculation with both Azotobacter and PSB 10+10 g/kg seed and foliar application of 7.5% (SWE) found more productive as it attained the superior values of yield attributing (traits), spikes/m², grains/spikes, test weight (g), grain yield (t/ha), straw yield (t/ha) and proved significantly superior over seed inoculation alone with Azotobacter or PSB without foliar application of (SWE). Though the former treatment fetched the higher values of net monitory return (117048.00 INR/ha) and final cost of cultivation (49594.00 INR/ha), but plots receiving seed inoculation with both Azotobacter and PSB 10+10 g/kg seed alone with foliar application of 5% (SWE) found more remunerative due to proportionate increase in benefit/over cost investment (2.46).
