A greenhouse experiment with green gram grown on boron (B) deficient calcareous soils was conducted for two years in Northwest India to study the influence of soil and foliar applied boron on green gram. Three soils with calcium carbonate content 0.75 (Soil I), 2.1 (Soil II) and 4.56 (Soil III) percent were collected from different sites of Ludhiana and Bhatinda districts, Punjab, India. The treatments comprised of four levels of soil applied boron viz. 0.5, 0.75, 1.0 and 1.5 mg B kg−1 and two levels of foliar applied boron viz. 0.1 and 0.2 per cent borax solution with common control. Soil applied boron has more influence on mean dry matter yield while foliar applied boron has on mean grain yield. Among all soil applied boron 0.5 mg kg−1 is best treatment while 0.1% is best foliar treatment. Soil applied boron was at the par with foliar applied boron. Among all three calcareous soils, Soil I with lower calcium carbonate was best soil in respect of mean yield and yield components in comparison to Soil II and Soil III. Combined effect of boron level and soils had a significant effect on yield and yield attributing characters. Total seed weight and leaf boron content are highly correlated with one another.
Soil applied boron was at par with foliar applied boron.
Among all soils, Soil with lower CaCO3 was best soil in respect of yield in comparison to soil with higher CaCO3.
