A field experiment was conducted to study the effect of seed rhizome size and plant spacing on growth, yield and quality of ginger (Zingiber officinale Rosc.) cv. Maran under coconut cropping system during Kharif-2014 at Horticultural College and Research Institute Farm, Anantharajupet, Y.S.R. Dist., Andhra Pradesh, India. The study comprised of three seed rhizome sizes viz., 20 g, 30 g and 40 g with five plant spacings viz., 25 cm × 15 cm, 25 cm × 25 cm, 30 cm × 20 cm, 30 cm × 30 cm and 40 cm × 20 cm. The experiment was laid out in a factorial randomized block design with three replications. The rhizome size of 40 g (S3) took least number of days to first sprouting of rhizome (12.73) followed by 30 g (S2). Similarly plant height at harvest (67.87 cm), number of tillers per plant (11.51) and leaf area index (3.59), yield per hectare (27.41 t), essential oil content (1.83%) and starch content (30.27%) were recorded maximum with 40 g seed rhizome size. Regarding plant spacing highest plant height (65.07 cm), leaf area index (5.25) and yield per hectare (26.40 t) was recorded from closest plant spacing of 25 cm × 15 cm (D1). The most satisfactory rhizome yield (38.06 t/ha) was found from the treatment combination of 40 g seed rhizome size with 25 cm × 15 cm plant spacing (S3D1). Source
