Growth and yield of ginger (Zingiber officinale Rosc.) as influenced by different seed size and spacing

Abstract

An experiment was carried out during 2016 and 2017 at Horticultural Research Station, Mondouri, BCKV (West Bengal) to identify the optimum size of seed rhizome and spacing of ginger (Zingiber officinale Roscoe) for production of cv. Gorubathan. Growth parameters viz., plant height, tillers per clump and leaves per clump increased with each successive growth stages i.e. 90 and 150 days after plantingDAP. Among different treatment combinations, maximum plant height (74.16 cm) was observed with rhizome size 25 g and spacing of 20 × 20 cm at 150 DAP. However, maximum number of tillers per clump (14.82) was observed with rhizome size 25 g and 20 × 15 cm spacing at 150 DAP. The highest number of leaves per clump (141.38) were noticed with 25 g, 25 × 20 cm at 150 DAP. Maximum weight of clump and length of clump (200.65 and 16.05 g) were recorded with combination of rhizome size 25 g and spacing 25 × 20 cm, respectively. Breadth of clump (12.54) was maximized with 25 g and 20 × 20 cm and projected yield (t ha-1) were recorded highest in planted with mother rhizome pieces directly sowing of 25 g, with the spacing of 20 × 15 cm (29.95 t ha-1).
