Quality parameters and yield of wheat under variable sowing dates and irrigation levels

Abstract

A field experiment was conducted during 2014-15 and 2015-16 at Research Farm of Department of
Soil Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar to estimate the quality
parameters and grain yield as affected by sowing dates and irrigation levels. The experiment was
laid-out in a strip-plot design with three replications on a sandy loam soil. Treatments comprised
four dates of sowing viz., October last week (D1), November 2nd week (D2) and December last week
(D3) and December last week (D4) and four irrigation levels viz., CRI (I1), CRI + heading (I2) and CRI
+ jointing + milking (I3) and CRI + late tillering + heading + milking (I4). Delay in sowing beyond D2
resulted in significantly lower yield attributes compared to earlier sowing dates. Quality parameters
viz., protein content and sedimentation value increased while hectoliter weight decreased with delay
in sowing during both years. On the other hand, protein content decreased while, sedimentation
value and hectoliter weight increased with increase in the frequency of irrigation during both study
years.
