Effect of irrigations on the basis of IW/CPE under sprinkler system on quality, yield and economics of potato

Potato is a one of important crop under North Gujarat condition. Irrigation management is about controlling the rate, amount, and timing of applied irrigation water in a planned and efficient manner. With the best irrigation management practices, a potato crop. The purpose of this experiment is to investigate the effect of levels of sprinkler irrigation on yield and quality of potato. The experiment was undertaken during rabi season of year 2018-19, 2019-20 and 2020-21 at Agricultural Research Station, S. D. Agricultural University, Aseda (Gujarat). The treatments comprised of three levels of irrigation (I₁: 0.8 IW/CPE, I₂: 1.0 IW/CPE and I₃: 1.2 IW/CPE) and four levels of depth of irrigation (D₁: 20 mm, D₂: 30 mm, D₃: 40 mm and D₄: 50 mm. The experiment was laid out in a large plot technique with four quadrate.Higher tuber yield (29.25 t/ha) and net return was recorded under the treatment I₃: 1.2 IW/CPE while lower value 24.84 t/ha found under the treatment I₁:0.8 IW/CPE. In case of depths of irrigation, D₁: 20 mm recorded significantly higher tuber yield (28.87 t/ha) and net return among all treatments while lower value (25.05 t/ha) was recorded under the 50 mm depth of irrigation. The combination of I₃D₁ (1.2 IW/CPE + 20 mm) recorded significantly higher tuber yield 31.92 t/ha, which was statistically at par with the treatment I₃D₂ and lower value was recorded under the treatment I₁D₄ (20.83t/ha).
