Boron tolerance in wheat in relation to soil salinity

A screenhouse study in Haryana in 1986/87 evaluated the effect of boron on the wheat cultivar WH147 grown in pots in a sandy soil at three salinities. Before sowing, 0-9 mg B/kg soil was added. Without added B the crop produced significantly more grain at electrical conductivity of the saturation extract (EC e ) 6 dS/m than at other salinities, but at EC e 8 dS/m yields were similar to those in nonsaline (EC e 0.8) soil. Grain yield in nonsaline soil was not affected significantly even at the highest concentration of added B, even though at the boot stage the shoots had accumulated as much as 307 mg B/kg (...)
