Effect of growth regulators on growth and rhizome production of ginger (Zingiber officinale Rosc.) in the hilly region of Darjeeling district.
Abstract: A field trial was conducted at the Horticultural Research Station, Bidhan Chandra Krishi Viswavidyalaya, Pedong, Darjeeling, West Bengal for two consecutive years to study the effect of growth regulators on growth and rhizome production of ginger cv. Gorubathan. Growth regulators like Ethrel @ 50,100,150ppm, Cycocel @ 100, 200, 500ppm and GA3 @ 50,100,150ppm and control (water spray) were sprayed at 90 and 120 days after planting. The results revealed that spraying with GA3 @ 150 ppm and Ethrel @ 150 ppm showed maximum plant height (103.38 cm.) and maximum number of pseudostem (5.23/clump) respectively. Maximum number of leaves per plant (72.19), maximum leaf length (29.69 cm.) and leaf breadth (2.80 cm.) were recorded in plants treated with Ethrel @ 100 ppm., GA3 @150 ppm and Cycocel @ 200 ppm respectively. The maximum yield (69.86 t/ha) was recorded in the treatment GA3 @150 ppm as compared to 45.60 t/ha in control. From this experiment it can be concluded that the foliar spray of GA3 150 ppm is the best for ginger cultivation.
