Boron (B), one of the essential micronutrients, plays vital role in plant growth. Thirty one field experiments were conducted to evaluate the response of wheat, rice and cotton to B application throughout Pakistan during 2005-08. Boron was applied at 1 kg per ha as Borax decahydrate (11.3% B) at different times along with recommended doses of N, P and K. The results revealed that B application at sowing time to wheat increased significantly the number of tillers per plant (15%), number of grains per spike (11%), 1000-grain weight (7%) and grain yield (10%) over control. Among the treatments, B application at sowing time showed best results followed by B application at 1st irrigation and at booting stage. In rice (coarse), B application before transplanting substantially increased number of tillers per hill (21%), plant height (3%), panicle length (10%), and number of paddy grains per panicle (17%), 1000-grain weight (11%) and paddy yield (31%) over control.
