Water Management - Drip Irrigation
Maize000015
  • Irrigation once in 2 days
  • Irrigation based on climatological approach
Irrigation volume = Pe x Kp x Kc x A x Wp – Re

  • Pe – Pan evaporation rate (mm/day)
  • Kp – Pan co-efficient (0.75 to 0.80)
  • Kc – Crop co-efficient (0.4 – Vegetative stage; 0.75 – Flowering stage; 1.05 – Grain formation stage)
  • A – Area (75 x 30 cm)
  • Wp – Wetted percentage (80% for maize)
  • Re – Effective rainfall (mm)
Irrigation duration = Water requirement per plant once in 2 days
No. of dripper / plant x Discharge rate (lph)
