SUMMARY
A field experiment was conducted during Rabi season of 2021-22 at Agronomy Research Farm, Chaudhary Charan Singh Haryana Agricultural University; Hisar to study the growth indices,
straw yield and harvest index of FIRB planted wheat as influenced by varieties and nitrogen sources under alternate furrow irrigation method. The experiment was carried out in split plot design with three replications. The four varieties (WH 1105, HD 3086, HD 2967 and WH 1184) were assisted in main plot and nitrogen sources viz. control, 100% RDN through urea, 50% RDN through urea + 50% RDN through VC and 50% RDN through urea + 25% RDN through VC + 25% RDN through FYM in sub plots on N equivalence basis. Among varieties, higher values of growth indices and straw yield were recorded with variety HD 3086, however, higher value of harvest index was recorded with HD 2967. Among nitrogen sources, 50 per cent RDN through urea + 25 per cent RDN through VC + 25 per cent RDN through FYM was found superior in respect of growth indices and straw yield over other nitrogen sources and control.
Key words: Growth indices, FIRB planted wheat, nitrogen sources, alternate furrow irrigation and straw yield
