Abstract
Ginger is one of the major spice grown in subtropical hilly regions and ultivation of ginger under coconut ecosystem is gaining popular among the farmers. Coimbatore district, Pollachi region is one of the major coconut growing belt in Tamilandu. With this view an experiment was conducted to evaluate the performance of ginger genotypes under coconut ecosystem at Coconut Research Station, Aliyar Nagar, Tamil Nadu Agricultural University, Coimbatore during 2018- 2020. . Fourteen ginger genotypes/ varieties were collected for this study. The ginger rhizomes were sown in the prepared land all cultural operations as per the TNAU recommendations were followed uniformly. Growth and yield parameters of ginger genotypes were recorded for three seasons. The date collected were pooled and analysed for statistical significance. Among the fourteen varieties of ginger, var. Athira excelled with respect to number of primary fingers (4.8), length of primary fingers (4.4 cm), diameter of primary finger (2.5 cm), number of secondary finger (5.7), days to maturity (248), TSS (10.40 Brix), acidity (0.41%), Dry matter content (18.9%), fibre content (9.6%), Essential oil content (11.2 mg/g of dry ginger), Gingerol content (19.6 mg/g of dry ginger ) and lowest incidence of soft rot (11.4 %). On the basis of good performance Athira is adjudged as the suitable ginger genotype under coconut shade condition of this region.
