Abstract
Not AvailableAn attempt was made to study the effect of three different maturity stages (90 days after planting, 140 days after planting and 180 days after planting) on growth, yield and quality of two Curcuma species viz., Curcuma aromatica Salisb. and Curcuma amada Roxb. Plant height, yield and dry recovery showed considerable variation over three growth stages. The two species differed significantly for plant height, dry recovery, yield, oil, curcumin and starch between the species as well as among the growth stages. The Species and growth stage interaction was also found to be significant. Fresh yield, dry recovery and starch gradually increased in both the species. Significant accumulation of photosynthate was evident even after 140 days of planting. Though the two species behaved more or less uniformly for all the aerial growth attributes, yield and starch, differential behavior of the two species was observed for curcumin, essential oil and protein content.Not Availabl
