Turmeric varieties are grown with drip irrigation and fertigation. First, it was found that there is variability in the vigor and yield expression in Turmeric when irrigated and fertigated with drip. In subsequent years (2016 and 2017) two varieties, BSR -2 and Salem local were grown with 3 different levels of fertigation, 75%, 100% and 125% of recommended dose (RDF) of NPK. In both years it was found that Salem local is a better performer and 125% RDF is supporting the highest yield of the crop of both varieties. Of the varieties, Salem local seems to be superior in its response to fertigation. Drip fertigation enhances water and fertilizer use efficiencies and supports efficient precision farming
