Field experiment was carried out at the Department of Horticulture, UAS, Bangalore, in well-drained red sandy loam soils of the experimental block with a pH of 6.2. The soil was low in organic carbon and available nitrogen, whereas available phosphorus and potassium were in medium range. The experiment consisted of two ginger cultivars (Rio-de-Janeiro and Himachal) and 11 fertigation levels which were replicated thrice in the RCBD. Among the eleven fertigation treatments tried on two ginger cultivars, significant variation was observed for growth and yield parameters. Maximum plant height at 30, 60, 90, 120, 150, 180 and 210 DAS was recorded with 200 per cent RDF (200:100:100 N: P205: K,0 kg /ha) through fertigation + FYM 30t/ha, Neem cake 2t/ha inboth the varieties. Maximum leaf area (1387.52 cm2 and 2708.02 cm2) and leaf area index (1.85 and 3.61) at harvest were also recorded in the same treatment for Rio-de- Janeiro and Himachal, respectively. Highest number of primary fingers, secondary fingers per clump, maximum fresh weight and length of mother rhizome, dry matter production at harvest were recorded with the application of 200 per cent RDF + neem cake @ 2 t ha~(-1) which was on par with the 150 per cent RDF along with 30 tons of FYM and 2tof neem cake in both the varieties. Highest growth and yield parameters were recorded in the Himachal variety as compared to Rio-de-Janeiro with respect to the fertigation levels.
