Determination of suitable irrigation schedule for optimum water use efficiency of wheat crop.

Krishna Deo, SR Mishra, AK Singh, AN Mishra, Ashish Singh and Sanjay Kumar

A field experiments was conducted during rabi seasons of 2014-2015 and 2015-2016 at the Agromet Farm, N.D. University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) The treatment comprised of four levels of irrigation schedule Viz., I1 (critical stages), I2 (0.6 IW: CPE ratio), I3 (0.8 IW: CPE ratio), and I4 (1:0 IW: CPE ratio). The findings of present investigation indicated that the grain and straw yields as well as most of the growth and yield attributes of wheat were significantly influence due to different irrigation schedule. The results, further revealed that growth attributes such as plant height (cm), number of shoots m-2 and Leaf area index (LAI) were found significantly higher under I1 (critical stages) treatment during both year 2014-15 and 2015-16. The total number of effective tillers m-2, length of spike (cm), harvest index (%) and test weight (gm) were found higher under I1 (critical stages) and I4 (1.0 IW: CPE ratio) treatment during both years. The highest grain yield (52.3 and 52.2 q/ha) and straw yield (65.8 and 66.9 q/ha) recorded under I1 (critical stages) treatment during the both years of 2014-15 and 2015-16. The lowest grain yield (51.2 and 51.9 q/ha) and straw yield (64.4 and 65.3 q/ha) was recorded under I2 (0.6 IW: CPE ratio) during both years. The highest WUE (16.42 and 16.70 kg ha-1 mm-1) was recorded under I2 (0.6 IW: CPE ratio) treatment and lowest (14.69 and 14.96 kg ha-1 mm-1) under I1 treatment.
