Abstract: A field experiment was conducted at Agronomy Research Area, CCS HAU Hisar to study the influence of nitrogen source and varieties on growth indices and harvest index of wheat cropduring rabi season of 2017-18 in split plot design with three replication. In the main plots there were five wheat varieties (WH 1105, WH 1142, HD 3086, HD 2967 and DBW88) and in sub plots three nitrogen sources viz. 100 RDN through inorganic source (urea), 100 per cent RDN through organic source (vermicompost) and 50 per cent RDN through inorganic + 50 per cent RDN through organic source. Higher leaf area index and leaf area duration was recorded under variety HD 3086and 100 % RDN through inorganic source (urea). Among varieties non significant differences were observed in respect of crop growth rate except at 31-60 days after sowing. Neither the varieties nor the nitrogen sources had any significant effect on relative growth rate, attraction index and harvest index.
