Effect of drip irrigation schedules and fertigation levels on growth parameters and yields of wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted during rabi seasons of 2017-18 and 2018-19 to study the effect of drip irrigation schedules and fertigation levels on growth parameters and yields of wheat (Triticum aestivum L.). The trial was laid out in split plot design with four replications, assigning total 16 combinations i.e. four irrigation schedules (0.6, 0.8, 1.0 PEF and surface irrigation at 0.8 IW/CPE ratio) in main plot and four fertigation levels (50%, 75%, 100% RDF through drip fertigation and 100 % RDF through soil application) in sub plots. The revealed that drip irrigation scheduling at 1.0 PEF enhance growth parameters and yields which ultimately resulted in higher grain and straw yields of rabi wheat over drip irrigation scheduling at 0.6 PEF and in fertigation levels 100 % RDF through drip significantly increase growth parameters and yields of rabi wheat over 50% RDF through drip fertigation.
