The study was conducted at Agronomy (Forage Production) Section, Ayub Agricultural Research Institute, Faisalabad, Pakistan during 2010-11 and 2011-12. The primary objective was to study effect of foliar application of urea on oat forage productivity and to enhance nitrogen use efficiency. Six foliar applications of urea viz. 0.5%, 1%, 1.5%, 2%, 2.5%, 3% along with 1/2 recommended dose of N (40 kg/ha) were compared with recommended dose of N (80 kg/ha) under Faisalabad conditions. Recommended dose of N as soil application was treated as control as no foliar application of urea was applied in this treatment. Oat variety CK-1 was sown using 80 kg seed/ha during second week of October 2010 and 2011 in RCBD at research area of the section. The crop was sown in 30 cm apart rows in net plot size of 3x6 meter. Maximum plant height (153.5 cm), number of tillers per plant (26.33) and green fodder yield (56.28 t/ha) was observed in T7 where recommended N dose as soil application (1/2 N at sowing and 1/2 N 60 DAS) was applied without foliar application of urea. The yield was statistically at par with treatment T3 (50.85 t/ha) where 1/2 N was applied at sowing along with 1.5% foliar spray of urea 60 DAS. The results showed that 1/2 recommend dose of N along with 1.5% foliar application of urea 60 DAS saved almost 1 bag of urea per hectare without affecting green fodder yield of oat.
