Abstract: A field experiment on ginger (Zingiber officinale Rose.) was conducted at the Horticulture Experimental Farm, College of Agriculture, Central Agricultural University, Imphal during 2007 and 2008 to study the growth and productivity of four varieties viz., Manipur local, Bhaisey, Gorubathan and Nadia. Among the varieties, Bhaisey showed earliness in sprouting, produced taller plants, recorded greater number of tillers per clump, higher canopy spread, leaf area index, dry matter accumulation, crop growth rate, rhizome bulking rate and yield than those of Nadia and Manipur local; and were closely followed by Gorubathan. The highest rhizome yield (20.46 t ha-1) was produced by Bhaisey followed by Gorubathan (19.13 t ha-1). Bhaisey also produced good quality rhizome having high specific gravity (1.25 g cc-1), dry matter (20.4%), oleoresin content (5.12%) and moderately low crude fiber content (5.71%). Dry matter content in rhizome showed positive relationship with specific gravity and oleoresin content; but crude fibre content was negatively related with dry matter and oleoresin content The results suggest growing of Bhaisey for producing higher yield with good quality of ginger at Manipur.
