The field experiment was conducted at experimental farm of Regional Research Sub-Station (Terai Zone), Uttar Banga Krishi Viswavidyalaya, Kharibari, Darjeeling, West Bengal during 2015-16 and 2016-17 to evaluate the response of turmeric to various levels of nitrogen (N) (0, 90, 120, 150 and 180 kg/ha) and potassium (K) (0, 100, 120 and 140 kg/ha). Both nitrogen and potassium, alone or in combination, had a significant effect on growth, yield and yield contributing characters and also quality characters of turmeric. However, the combined effect of N and K increased the growth, yield and other yield parameters up to N180K140 kg/ha and significantly differed over the control (N0K0). The maximum plant height (144.4 cm), number of leaves per plant (9.37), number of tillers per clump (3.65), leaf length (59.7 cm), leaf area (534.4 cm2), number of primary fingers per rhizome (9.25) were recorded with N180K140 treatment. Similarly, mother rhizome length (8.30 cm), primary finger length (8.42 cm), fresh weight of mother rhizome (39.25 g) and fresh weight of primary finger (38.92 g) were also significantly recorded maximum with N180K140 treatment. The highest fresh rhizome weight (432.7 g), fresh yield (25.3 t/ha) and curing percent (21.2%) were recorded with treatment combination of N180K140 treatment, while all the growth as well as yield parameters were found to be lowest with the absolute control (N0K0).
