Field experiment was conducted to determine the effects of planting patterns and time of nitrogen (N) application on growth, yield and quality of wheat in a split plot design during Rabi 2011–12 and 2012–13. The treatments consisted of three planting pattern (M1-3 rows at 20 cm inter-row spacing and 40 cm space between two sets of rows, M2-2 rows at 20 cm inter-row spacing and 40 cm space between two sets of rows, M3-Normal sowing at 20cm row spacing) in the main plots and six N scheduling (T1-Control:; T2- 1/2 dose of recommended N basal+ 1/2 dose of recommended N with 1st irrigation; T3- No basal+ 1/2 dose of recommended N with 1st irrigation + 1/2 dose of recommended N with 2nd irrigation ; T4- 3/4 dose of recommended N basal+ 1/4 dose of recommended N with 1st irrigation; T5- 1/4 dose of recommended N basal+ 3/4 dose of recommended N with 1st irrigation; T6- 1/4 dose of recommended N basal+ 1/4 dose of recommended N with 1st irrigation + 1/2 dose of recommended N with 2nd irrigation) in sub- plots. The treatments were replicated three times. Results revealed that M1 and M3 methods produced non-significant (p<0.05) grain yield i.e. 54.2, 51.4 and 52.1, 49.8 q/ha, respectively and significantly lower than M2 during both the years of study. Higher values of crop growth rate (CGR) and leaf area duration (LAD) at 90 days after sowing (DAS) were observed in M1 as compared to M2 and M3. Split applications of nitrogen significantly affect the yield and yield contribution characters. When nitrogen applied as 1/4th as basal+1/4th after 1st irrigation+1/2 after 2nd irrigation (T6), it had 37.2, 4.8, 5.3, 8.7, 3.4 % and 34.8, 5.1, 6.7, 10.7, 7.1% higher grain yield than T1, T2, T3, T4 and T5 treatments during 2011-12 and 2012-13, respectively. Quality parameters of wheat were also better under T6 treatment.
