A field experiment was conducted on farmers' fields in Sankumari village, Nabarangpur district, Odisha's Eastern Ghat High Land (EGHL) zone, during the kharif 2016 season to investigate the impact of boron application on maize yield and economics. Due to its photo insensitivity, maize has been grown in a variety of seasons and locations for crop durations varying from 90 to 130 days. Because maize is a C4 plant, it has a larger yield potential that is also influenced by the soil's nutrient delivery capacity. Four treatments were duplicated five times in this study, which used a Randomized Block Design. The soils used in the experiments were slightly acidic, non-saline loamy sands with a medium level of organic carbon and available K but low amounts of available N, P, B, and Zn. Soil Test Based NPKZn @ 150:75:60:1 had the maximum possible grain yield per cob (210.21 g), 100 seeds weight (38.16 g), stover production (8.10 t ha-1), grain yield (6.52 t ha-1), total dry biomass (14.62 t ha-1), harvest index (44.59 percent), and B:C ratio (1.90). 6.25 kg ha-1 + 0.5 kg B ha-1 soil application + 0.2 percent borax foliar spray at 30 and 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). As a result, farmers in Odisha's EGHL zone must use the Soil Test Based Boron Fertiliser Application to grow remunerative maize in soil lacking in boron.
