Abstract:

The field experiment was conducted at Agronomy Farm, Anand Agricultural University, Anand (Lat.: 22035’ N, Log.: 72055’ E & 45.1 m above msl) during rabi season in 2011-2012. The treatment comprised of five levels of irrigation schedule Viz., I1 (CRI, TL, BT, FL, ML, SD), I2 (0.4 IW: CPE ratio), I3 (0.6 IW: CPE ratio), I4 (0.8 IW: CPE ratio) and I5 (1.0 IW: CPE ratio) in randomized block design (RBD) within four replications. The main aim is to quantify the agrometeorological indices of wheat crop. The different agrometeorological indices were evaluated i.e. growing degree Days (GDD), Heliothermal Unit (HTU), Photothermal Unit (PTU) and Relative temperature Disparity (RTD). The results revealed that the different irrigation level was found alter the agrometeorological indices and its efficiency at different phenophases of wheat crop. The higher GDD (35320C day), HTU (32759 0C day), and PTU (38652 0C day) were found with I1 (CRI, TL, BT, FL, ML, SD) irrigation level. The relative temperature disparity (RTD) was found higher under I3 (0.6 IW: CPE ratio) irrigation level and photothermal index (PTI) was found varying as fluctuating trend among all irrigation levels.
