Abstract
A field experiment was conducted during kharif season of 2022 to evaluate the effect of different NPK levels and bio-inoculants on growth, yield and economics of NDR-2065. Factorial Experiment was laid out in completely randomized block design involving three NPK levels i.e. control, 60% RDF, 80% RDF and 100% RDF in combination with three levels of bio- organics viz. BGA + PSB, Azolla + PSB and BGA + Azolla + PSB along with seven treatment combinations replicated thrice. The total per ha-1 paddy and straw yield of rice varieties amounted a sum of ₹ 122721 for T5 (80% RDF + 500kg Azolla ha-1 Soil application + PSB), ₹ 116048 for T2 100% RDF (150, 60, 40 N2, P2O5, K2O kg ha-1), ₹ 111108 for T3 (80% RDF + 10 kg BGA ha-1 Soil application + PSB), ₹ 107709 for T6 (60% RDF + 500kg Azolla ha-1 Soil application +PSB) and ₹ 86580 for T1 under control. The Benefit Cost Ratio (BCR) was higher for T5 having value of 2.0 and least for T1 with a value of 1.3. The treatment combination T2, T6 and T3 presented a close value of Benefit Cost Ratio (BCR) with respect to each other viz. 1.8, 1.7 and 1.7 respectively.
