Abstract:
A field experiment was conducted to find out the nutritional efficiency and yield performance of different Rhizobium isolates in groundnut var. GG-20 during three consecutive kharif seasons of 2016-17, 2017-18 and 2018-19 at Junagadh Agricultural University, Junagadh. The results revealed that the seed treatment of groundnut with Rhizobium leguminosarum isolate-1 (10⁷ cfu/ml) at the rate of 10 ml/kg of seeds along with soil application of recommended dose (RD) of P₂O₅ (25 kg/ha) and K₂O (50 kg/ha) and 75% RD of N (9.4 kg/ha) at the time of sowing gave higher pod yield 1502 kg/ha and net return of ₹ 25439 with ICBR of 1: 8.69. But, the maximum nitrogen use efficiency (72.16) was found in seed treatment of Rhizobium leguminosarum isolate-1 (10⁷ cfu/g) @ 10 ml/kg of seeds along with soil application of recommended dose (RD) of P₂O₅ (25 kg/ha) and K₂O (50 kg/ha) and 50% RD of Nitrogen (6.25 kg/ha) as compared to other treatments.
