Abstract
A field study was carried out during 2012-13 at Sindh Agriculture University, Tandojam, Pakistan, geographically latitude 25？N and longitude 68？E, to assess the effect of foliar applied urea on the growth and yield of sunflower. The experiment was laid out in a three-replicated Randomized Complete Block Design. Five treatments were tested against sunflower variety Hysun-33 which included: T1= Control (no urea), T2 = Recommended urea soil applied (130 kg·ha﹣1) at sowing stage, T3 = 1% urea at 35 days after sowing, T4 = 1% urea at 60 days after sowing and T5 = 1% urea at 85 days after sowing. The results revealed that growth and yield characters as well as oil yield of sunflower were significantly (P 0.05); but differences were significant (P < 0.05) when compared with foliar application after 35 days of sowing and rest of the treatments.
