Abstract:
A field experiment is conducted in randomized block design with three replications at the Agricultural Research Farm of Lovely Professional University, Phagwara, Punjab. The experiment comprising, ten different treatments viz. T0(control), T1-75% RDN (50% N at Basal + 50% N at CRI stage, T2- 100% RDN (50% N at Basal + 25% N at CRI + 25% N at Tillering stage, T3-125% RDN (50% N at Basal + 25% N at CRI + 25% N at Tillering stage, T4-75% RDN (50% N at Basal + 25% N at CRI + 25% N at Tillering stage, T5-100% RDN (25% N at Basal + 25% N at CRI + 50% N at Tillering stage, T6-125% RDN (25% N at Basal + 25% N at CRI + 50% N at Tillering + 3% Urea solution spray at Late Jointing stage, T7-75% RDN (25% N at Basal + 25% N at CRI + 50% N at Tillering stage, T8-100% RDN (25% N at Basal + 50% N at CRI + 25% N at Tillering stage+ 3% Urea solution spray at Jointing stage, T9-125% RDN(50% N at Basal +50% N at CRI stage + 4% urea solution spray at Flowering stage. The application of 125% RND (25% N at Basal + 25% N at CRI + 50% N at Tillering+ 3% Urea solution spray at Late Jointing stage) recorded significant growth and yield parameters viz. plant height, leaf area index, days to 75% flowering, number of tillers, spike per meter square, length of spike, number of grain per spike, test weight, grain yield (47.7 q/ha) and straw yield (70 q/ha).
