A field experiment was conducted from 23rd March to 31st May-2019 to evaluate the effect of drip irrigation levels on amaranthus (Amaranthus hybridus L) yield and water use efficiency under shade-net. The experiment was laid out in a randomized block design (RBD) with five treatments (60%, 80%, 100% and 120% of water requirement using drip irrigation and 100% of water requirement using furrow irrigation) and four replications. The findings of the investigation revealed that the highest yields in terms of fresh leaves weight per plant (63.89 g), fresh stem weight per plant (85.44 g), economic yield per plant (149.33 g), fresh shoot weight per plant (164.75 g), fresh root weight per plant (16.75 g), fresh biomass (330.83 g) and economic yield per hectare (22.69 t ha-1) investigated for different irrigation treatments were obtained by irrigating amaranthus crop with 100% of water requirement using drip irrigation and the lowest economic yield per hectare (14.20 t ha-1) was obtained by irrigating the crop with 60% of water requirement using drip irrigation. The maximum and minimum water use efficiency (7.95 kg m-3) and (3.89 kg m-3) were obtained by irrigating the crop with 80% of water requirement using drip irrigation and 100% of water requirement using furrow irrigation.
