Influence of foliar application of zinc (Zn) and boron (B) on seed cotton yield was investigated at Adaptive Research Farm, Vehari, Pakistan during 2007 and 2008. Seven treatments of Zn+B viz. 0.00+0.00, 0.75+0.00, 0.00+1.00, 0.75+1.00, 1.50+0.00, 0.00+2.00 and 1.50+2.00 kg per hectare were applied as zinc sulphate and boric acid, respectively. The results revealed that foliar application of Zn and B @ 0.75+1.00 kg proved as the best balanced fertilizer dose for higher seed cotton yield (2183.68 kg/ha) along with recommended dose of 170-57-62 kg NPK per hectare with higher number of bolls (26.7/plant) and boll weight (2.97g). The value cost ratio was the highest (8.93) when Zn was applied @ 1.50 kg. The data indicated significant relationship (R 2=0.91; 0.97, n=7) among boll number, boll weight and seed cotton yield.
