The field experiment was carried out at CRS, Masodha of ANDUA&T, Kumarganj, Ayodhya, India during Rabi Season 2019-20 to study the "Effect of different doses of Nitrogen and Plant growth regulator on growth and yield parameters of wheat (Triticumaestivum L.)"The experiment was laid out in Randomised Block Design with 3 replications. With 10 treatments namely T1- Absolute control (No Nitrogen and no growth regulators spray), T2-50% recommended dose of N, T3-75% recommended dose of N, T4-100% recommended dose of N, T5-125% recommended dose of N, T6-150% recommended dose of N, T7- 75% recommended dose of N with Lihocin spray at first node and boot leaf stage, T8- 100 % recommended dose of N with Lihocin spray at first node and boot leaf stage, T9-125% recommended dose of N with Lihocin spray at first node and boot leaf stage and T10-150% recommended dose of N with Lihocin spray at first node and boot leaf stage.-The scrutiny of data on growth yield attributes and yield clearly reveals that the application of 150% recommended dose of N with Lihocin spray at first node and boot leaf stage gave significantly the high values of growth, yield attributes and yields over rest of all.
