Abstract
The response of wheat (variety Blue Silver) to high soil B (Boron) was studied in a pot experiment by employing 0, 5, 10, 15, and 20 mg B Kg*1 (corresponding to 0.4, 3.5, 5.3, 7.0 and 9.0 mg kg'1 available B) in a clay loam soil. At about 8 3 mg kg'1 available B in soil, wheat straw and grain contained 290 and 15 /Xgg'1 B respectively, which resulted in a 50% reduction in yield. The adverse effect of soil B on yield occurred even at the minimal level of soil B i.e. < 5 mg kg"1 .
