Abstract
Ten varieties of ginger were evaluated for yield and quality attributes under hill zone of Karnataka at Department of Plantation, Spices, Medicinal and Aromatic Crops, College of Horticulture Mudigere. Significant differences among the varieties were observed for yield and quality characteristics. Results indicated that variety Maran recorded higher fresh rhizome yield of 29.37 t/ha which was followed by Rio-de-Janeiro (28.04 t/ha) and Karkal Local (25.84 t/ha). The highest crude fibre content was recorded in variety Karkal Local (6.73%) and the lowest was recorded in variety IISR-Varada (3.70%). Essential oil content was maximum in variety Rio-de-Janeiro (2.31%) and minimum was recorded in variety Humanabad Local (1.06%). The oleoresin content was maximum in Rio-de-Janeiro (9.06%) and minimum was recorded in variety Himagiri (4.20%). Among the ginger varieties Maran, Rio-de-Janeiro and Karkal Local showed better performance with respect to yield and quality parameters and found promising suitable varieties for rainfed situations of hilly region of Karnataka.
