Abstract

A field experiment was conducted to assess the effect of foliar nutrition and bio-inoculants on growth and yieldof black gram under Northern Transition Zone of Karnataka during kharif, 2020 at Main Agricultural Research Station,UAS, Dharwad with 11 treatments, which includes foliar spray of Dharwad nutrient mixture (DNM), Water soluble all 19(19:19:19), Di-ammonium Phosphate (DAP), Urea and Pink Pigmented Facultative Methylotrophs (PPFM) with andwithout soil application of mycorrhizal consortium and their combinations. The treatments were replicated thrice in arandomized block design. Among the treatments, soil application of mycorrhizal consortium @ 15 kg ha-1 at the time ofsowing in the furrows and spraying of Dharwad nutrient mixture (DNM) @ 2 per cent at flowering and pod formationstage improved the growth parameters such as plant height (85.0 cm), stem girth (0.72 cm), plant spread (39.1 cm), drymatter production (32.65 g plant-1) and seed yield (1,180 kg ha-1) over the recommended production practice alone(25:50 N, P kg ha-1 + seed treatment with Rhizobium @ 200 g + PSB @ 200 g).
