Abstract

The rhizome seed size and plant spacing is important factor that affects the growth and yield of ginger. Two year an experiment was conducted on seed rhizome size and intra row spacing of ginger cv. Gorubathan to determine the optimum rhizome size and optimum plant spacing for yield enhancement. The experiment was conducted at the Regional Research Station (OAZ), UBKV, Majhian, during 2020-2021. The experiment considered with three different rhizome sizes (20g, 30g and 40g) and five different plant spacing (20 × 20 cm, 25 × 20 cm, 25 × 25 cm, 30 × 25 cm and 30 × 30 cm) combination following randomized block design with three replications. From the pooled data resulted larger size rhizome seed (40g) and 25 cm × 20 cm plant spacing combination resulted significantly increase and maximum value for plant height at harvest (72.08 cm), number of tillers per plant-1 (12), number of leaves plant-1 (134.50), rhizome length (18.16) and rhizome yield plant-1 (249.95 g) whereas 20g seed size significantly reduced yield component traits. The correlation study of yield component traits revealed that positive and significant association of rhizome yield exerted with number of tiller plant-1, number of leaves plant-1 and rhizome length.
