Evaluating Sub Surface Drip Irrigation in Maize-based Cropping Sequence
Achievements:
The study conducted on sub-surface drip irrigation (SSDI) at different lateral pressures and depths in a maize-based cropping sequence (maize-tomatobaby corn) at Bhubaneswar indicated that the combination of pressure (at 125 kPa) and depth (15 cm) saved 18–19% water and improved yield and water productivity by 12–15% and 33–34%, respectively, when compared with surface drip irrigation (SDI) in tomato and baby corn crops. During kharif season, the yield of maize (Sweet corn) under SSDI at 0.8 m lateral spacing and irrigation at 100% ETc was found statistically at par with that under SDI.
