Effect of Irrigation and Fertility Levels under Drip Irrigation on Yield and Economics of Mentha (Mentha arvensis)-Okra (Abelmoschus esculentus) -Potato (Solenum tuberosum) Cropping System

摘要

The system productivity of mentha-okra-potatp in terms of mentha equivalent yield was highest with the application of drip irrigation at 100% PE than other treatments which was higher by 73% over the surface irrigation of 6 cm depth. The maximum wateruse efficiency (82.52 kg/ha/mm) was observed from drip irrigation at 60% PE, followed by drip irrigation at 80% PE (76.86 kg/ha/mm). However, lowest water-use-efficiency (32.91 kg/ha/mm) was observed in case of surface irrigation of 6 cm depth. Maximum
