Yield and quality of ginger (Zingiber officinale Rosc.) varieties grown in Assam

Abstract

Twenty indigenous and exotic varieties of ginger were evaluated for yield and quality. Significant variations in yield were observed among the varieties. Nadia yielded the highest (67.0 q/ha-fresh ginger) followed by Chekerella (57.0 qlha). Growth attributes like leaves per clump, tillers per clump and shoot height were positively correlated with yield. Moran, Jorhat hard, Thinladium and Wynad were fibrous. Moran and Jorhat hard yielded higher volatile oil and acetone extract. The fibrous varieties Moran and Jorhat hard were suitable for extraction of oleoresin and volatile oil.
