Effect of Irrigation Scheduling Based-IW/CPE Ratio on Soil Qualities, Growth Characteristics and Yield of Wheat (Triticum aestivum L.) Crop in Eastern Uttar Pradesh, India

This study aimed to assess the Effect of irrigation scheduling based on the IW/CPE ratio on soil qualities, growth characteristics and yield of wheat in Eastern Uttar Pradesh. A field experiment was conducted during rabi season of the year 2016-17. In this experiment, the treatment combinations consisting of five irrigation levels viz., CRI stage (I1), 0.6 IW/CPE ratio (I2), 0.8 IW/CPE ratio (I3), 1.0 IW/CPE ratio (I4), and 1.2 IW/CPE ratio (I5) were tried in randomized block design. Whereas the initial irrigation of all treatments is done at the CRI stage (21 DAS), and then, according to the IW/CPE ratio treatments, the crop of the net plot area was harvested from the individual plot for observation. The final seed weight per plot was recorded in kg and converted to q/ha. The result showed the growth attributes, viz., plant height, dry matter accumulation, number of effective shoots per m2, and yield-attributing characters, viz., 1000 grain weight, harvest index, grain, straw, and Biological yield by crop was significantly higher at 1.0 IW/CPE ratio (I4) in the moisture regime, which was at par with 1.2 IW/CPE ratio (I5) in the moisture regime and significantly higher than at the CRI stage (I1), 0.6 IW/CPE ratio (I2), and 0.8 IW/CPE ratio (I3).
