Born Effects on Yield and Yield Components of Cotton (Gossypium hirsutum)

Field experiments were carried out to study the response of yield and yield components of cotton (Gossypium hirsutum) to different rates of boron (B) fertilizer. B was applied as foliar at rates 0, 500 and 1000 g ha . Stat istical results of study indicated that foliar application of B significantly (P ≤ 0.05) increased l 1 number, boll weight, seed cotton yield and lint yield. In addition, leaf blade B concentration was affected by B application rate and increased significantly. Results also demonstrated that the highest seed cotton yield was recorded in case of 1000 g ha foliar application of B and this foliar application rate resulted in 25% 1
