Effect of irrigation scheduling on physiological characters and yield of different cultivars of wheat under varying sowing dates

Abstract

A field experiment was conducted under loamy sand soil during two consecutive Rabi seasons of 2016-17 and 2017-18 at Research Farm, Rajasthan Agricultural Research Institute, Sri Karan Narendra Agriculture University, Durgapura, Jobner. The experiment comprises four irrigation scheduling treatments (Irrigation at 0.6 ETc, 0.8 ETc, 1.0 ETc and 1.2 ETc), three cultivars (Raj 4120, Raj 4079 and Raj 4238) and three dates of sowing (15th November, 30th November and 15th December) assigned, respectively to main plot, sub plot and sub-sub plots were replicated three times in split plot design. Results revealed that irrigation scheduling at 1.2 Etc significantly influenced the RWC, MSI, Chlorophyll, Protein content and yield of different cultivars of wheat under varying sowing dates according to pooled analysis.
