Abstract

Field experiments were carried out to explore the impact of crop geometry and dripper spacing on the growth, yield and water-use-efficiency (WUE) in turmeric (Curcuma longa) raised with single bud transplants at ARS, TNAU, Bhavani Sagar, Erode district, Tamil Nadu, India. The treatment structure includes 2 drippers spacing viz., 60 cm and 40 cm with combination of 4 crop geometry viz., 30 × 15 cm, 30 × 20 cm, 30 × 25 cm and 45 × 15 cm and with conventional (surface) irrigation method as control. The trials were laid out in a randomized block design (RBD) and repeated thrice. The irrigation is being applied once in 3 days through drip at 80 % Pan Evaporation (PE) which is common for all the treatments except the conventional method. The fertigation is being given once in 10 days by following the fertigation schedule developed for turmeric. The findings disclosed that drip irrigation (DI) at 80 % PE with 60 cm spacing of dripper and crop geometry of 30 × 20 cm recorded higher turmeric yield as well as high income and B:C ratio. Significantly the lowest yield was obtained in the control treatment (conventional method). Hence the cultivation of turmeric utilizing the drip irrigation system demonstrated a reduction in water consumption by 48 % in comparison to conventional irrigation method, with a WUE varying from 19.4 - 26.5 kg ha-1 mm-1.
