Abstract
A field experiment was conducted at Kumarganj, Ayodhya during Rabi season of 2017-18 to evaluate the effect of irrigation schedules on productivity of late sown varieties of wheat (Triticum aestivum L.). Result revealed that the irrigation schedules significantly affected grain and straw yields as well as most of the growth and their attributes of wheat. 1.0 IW/CPE ratio recorded highest plant height (92.94 cm), number of tillers (389.24 m-2), dry matter accumulation (882.50 g m-2) at harvest stage and LAI (4.98) at 90 DAS as well as higher grain (37.40 q ha-1), straw yield (50.86 q ha-1) and biological yield (88.25 q ha-1) over rest of the irrigation schedules. Among the varieties number of tillers (386.74 m-2), dry matter accumulation (989.93 g m-2), grain yield (42.00 q ha-1), straw yield (56.99 q ha-1) and biological yield (98.99 q ha-1) were significantly recorded maximum with PBW- 373 while plant height (91.20 cm), and LAI (4.88) were recorded maximum with HUW- 234 at harvest stage.
