A field experiment was conducted in participatory mode on farmers’ field in Sankumari village of Nabarangpur district under Eastern Ghat High Land (EGHL) zone of Odisha during kharif 2016 to assess the response of boron application on yield and economics of maize. The experiment was laid out in Randomized Block Design with four treatments replicated five times. The experimental soils were slightly acidic, non-saline, loamy sand, medium in organic carbon and available K; low in available N, P, B and Zn contents. The maximum grain yield per cob (210.21 g), 100 seeds weight (38.16 g), stover yield (8.10 t ha−1), grain yield (6.52 t ha−1), total dry biomass (14.62 t ha−1), harvest index (44.59%) and B: C ratio (1.90) were recorded in Soil Test Based NPKZn @ 150: 75: 60: 6.25 kg ha−1 + 0.5 kg B ha−1 soil application + 0.2% borax as foliar spray at 30 & 45 DAS (T4) followed by Soil Test Based NPKZn @ 150: 75: 60: 6.25 kg ha−1 + 1.0 kg B ha−1(T3) over control (i.e. Soil Test Based NPKZn @ 150: 75: 60: 6.25 kg ha−1+ 0 kg B ha−1). Hence, Soil Test Based fertilizer application with boron is to be followed in soil deficient in boron under continuous maize growing areas of EGHL zone of Odisha for remunerative maize production by the farmers.
Soil Test Based NPKZn @ 150: 75: 60: 6.25 kg ha−1 + 0.5 kg B ha−1 soil application + 0.2% borax as foliar spray at 30 & 45 days after sowing (DAS) in maize is profitable and it improves productivity.
