Abstract:
A field experiment was conducted during Rabi 2018-19 and 2019-20 at CSK HPKV, Palampur to study the physiological response of wheat at different dates of sowing under various irrigation regimes methods in mid-hills of Himachal Pradesh. Sowing of wheat on different dates recorded significant physiological responses. Crop sown on 25^th October reported significantly higher value of growth indices while lowest values were found in 10^th December sown crop. Irrigation regimes also have significant effect on these parameters which directly contribute to crop yield. Initially growth rates were significantly higher in the treatments having three irrigations remaining at par with two irrigations. But in later stages, regimes of irrigation as per the recommendation of modified Penman-Monteith method and spatial data have recorded significantly higher growth rates remaining statistically similar with three irrigations. It means regimes of irrigation as per recommendation not only saves water but also increases the growth parameters of crop.
