A field experiment was conducted to study the nutrient uptake in turmeric under drip and micro sprinkler fertigation and its effects on fresh rhizome yield during July-February of 2015-16 at Tamil Nadu Agricultural University. The treatments comprised of two micro irrigation systems (drip and micro sprinkler) with three irrigation levels viz., 80, 100 and 120% of evaporation from a Class A Pan evaporimeter and two levels of fertigation viz., 75 and 100% RDF with water soluble fertilizers (WSF) (urea, MAP and MOP). Surface irrigation (5 cm depth) + soil application of fertilizers at 100% RDF was the control. The result indicated that higher turmeric yield was noticed under drip irrigation at 120% PE + fertigation with 100% RDF which is statistically on par with micro sprinkler irrigation at 120% PE + fertigation with 100% RDF. This may be due to maximum uptake of nitrogen, phosphorus and potassium in irrigation at 120% PE + fertigation with 100% RDF in drip and micro sprinkler systems.
