Evaluation of Ginger (Zingiber officinale Rosc.) Germplasms for Growth and Yield Attributes in the New Alluvial Zone of West Bengal

Abstract

An experiment was conducted to assess the growth and yield attributes of ginger germplasm at Horticultural Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal during 2019–20 and 2020–21. The experiment was designed in Randomized Block Design with 3 replications. A total of 18 treatments, comprising 15 germplasms and 3 varieties were evaluated. The results of the study revealed that Gorubathan has recorded maximum plant height, number of leaves per tiller, pseudostem girth, and dry yield. Surabhi recorded maximum leaf length, number of tillers per clump, leaf area, leaf area index, number of fingers per clump, number of primary fingers per clump, number of secondary fingers per clump, clump length, rhizome yield per clump, rhizome yield per plot and projected fresh rhizome yield, which was statistically at par with Hui local for rhizome yield per clump, yield per plot and projected rhizome yield, whereas maximum leaf breadth and finger diameter were recorded in genotype Hui Local. The maximum clump breadth was recorded in Thingpuidum Local and the highest finger length was found in Banada Local. In conclusion, the study suggests that var Surabhi, Gorubathan, Nadia and cv Hui Local, Thinglaidum, Thingpuri and Banada Local are found to be promising in terms of growth and yield attributes in new alluvial zone of West Bengal.
