Abstract:
The present investigation entitled “Canopy temperature (^oC) above and below and Relative Water Content (%) of leaves as affected by various treatments for wheat (Triticum aestivum L.)” was conducted at Instructional Farm of Acharya Narendra Deva University of Agriculture and Technology Kumarganj, Ayodhya (U.P.) during rabi season of 2020-2021 and 2021-2022: to study the Canopy temperature (^oC) above and below canopy of wheat as affected by various treatments (2020-21 and 2021-22) Relative Water Content (%) of leaves for wheat as affected by various treatments (2020-21 and 2021-22). Canopy temperature (^oC) of wheat at top and bottom of the canopy as affected by different date of sowing /weather variability and varieties recorded at successive stages during both the years. RWC was significantly influenced due to varieties at all the stages. V₃ recorded significantly RWC at all the stages which was at par with V₂ and significant over V₃ treatment at all the stages during both the years of investigation. RWC was significantly influenced due to seed rates at all the stages except 45 DAS and 90 DAS. PBW-343recorded significantly RWC at all the stages which was at par with HD-2824and significant over HUW -234 at all the stages during both the years of investigation. Experiment was conducted at Students Instructional Farm, Acharya Narendra Deva University of Agriculture and Technology Kumarganj Ayodhya (U.P.), which is geographically situated between 26°.47’N latitude to 82°.12’E longitude and at an altitude of 113 m above mean sea level. Geographically, Ayodhya falls under semi-arid and sub-tropical climate of Indo-Gangatic plains having alluvial calcareous soil. The average annual precipitation is about 1001 mm of which 85-90 per cent received during monsoon period i.e. between June to September. The maximum temperature reaches to its peak (40-45°C) during May while the minimum temperature is quite low (12-15 °C) during December and January. The experiment was carried out in randomized block design with three dates of sowing (15^th Nov 2020, 25^th Nov 2020 and 05^th Dec 2020) and (15^th Nov 2021, 25^th Nov 2021 and 05^th Dec 2021) and three cultivars (HD-2824, PBW-343 and HUW-234) there replicated three time. The experimental field was divided into 27 plots. Each the plot has gross size of 5.0m x 4.0m and row to row space was maintained at 20 cm.
