Manuscript effect of temperature on morpho-physiological traits with respect of grain yield of basmati rice

Abstract

The field experiment was conducted at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.), during kharif season 2016 and 2017. The design in split-plot with three replication and three dates of transplanting i.e., first date of transplanting (D1),second date of transplanting (D2) and third transplanting (D3) conditions were allocated in the main plots and four basmati rice varieties V1 (PB-1), V2 (PB-1509), V3 (PB-6), and V4 (PB-1121), in sub plot. The significantly higher to plant height in cm first date of transplanting i.e., (D1) with 31.35 and 32.87 cm at 30 DAT, 72.79 and 73.36 cm at 60 DAT, 90.80 and 91.04 cm at 90 DAT, 99.20 and 98.46 cm at harvest stage (DAT), while minimum in third transplanting date (D3) with 20.37 and 21.56 cm at 30 DAT, 64.28 and 65.82 cm at 60 DAT, 81.32 and 82.91 cm at 90 DAT, 89.46 and 91.11 cm at harvesting stage of concerning years respectively. observed significantly higher plant height with variety V4 i.e., 28.30 and 29.48 cm at 30 DAT, 74.37 and 75.61 cm at 60 DAT, 91.86 and 92.40 cm at 90 DAT, 102.25 and 103.02 cm at harvest DAT followed by variety V1 with 26.90 and 28.60; 69.12 and 70.43; 87.84 and 89.10; 96.23 and 97.39 cm meanwhile, minimum in variety V2 with 23.17 and 24.08; 63.05 and 63.89; 78.97 and 80.72; 83.89 and 85.10 experimentation, respectively.
