Abstract

A study was carried out to evaluate the performance of different types of automated drip irrigation system on bhendi during rabi 2019-20 and rabi 2020-21 at the drip automation unit, Tamil Nadu Agricultural University. An approach of irrigation scheduling comprising of 4 different automated drip irrigation systems are time based drip irrigation, volume based drip irrigation, soil moisture sensor based irrigation, switching tensiometer based irrigation which was compared with the surface method of irrigation. The results revealed that tensiometer based drip irrigation recorded higher plant height of 108.29 and 107.58 cm at final harvest stage, dry matter production of 4686 and 4667 kg ha-1 at final harvest stage and fruit yield of 23.86 and 24.05 t ha-1 during rabi 2019-20 and rabi 2020-21 resulting in increment over conventional method of irrigation. However, the above treatment was followed by soil moisture sensor based drip both years of study. Automated drip irrigation using sensors
