Abstract: The field trial was carried out at the Central Experiment Station, Wakawali, Dapoli during kharif season of the year, 2016 to assess the periodic vegetative growth in different genotypes of colocasia. In all sixteen genotypes were evaluated for their growth performance. All the genotypes showed wide range of variation at every fifteen days of interval after planting. Among the sixteen colocasia genotypes evaluated, maximum plant height was recorded in AC-20 (60.34 cm) and minimum plant height was recorded inBCC-11 (45.82 cm). The maximum leaf thickness (0.538 mm) was recorded in genotype Mahim. Whereas, minimum leaf thickness (0.473 mm) was recorded in Kelva genotype. Significantly maximum number of leaves plant^-1 (17.47 plant­^-1) was recorded in genotype M-9-111 followed by Sanjivini (16.00 plant^-1) and SreePallavi (15.13 plant^-1). Whereas, less number of leaves plant^-1 (12.27 plant^-1) was recorded in Khopoli genotype. A higher value of leaf length (55.86 cm) was recorded in genotype Sree Pallavi (G₁₁) and minimum leaf length (43.03 cm) was recorded by NDB-9 genotype. The maximum leaf breadth (42.50 cm) was also recorded in Sree Pallavi genotype. However, minimum leaf length (31.52 cm) was in Kelva genotype. Petiole length (was maximum 57.55 cm) in genotype AC-20 and lowest petiole length (43.14 cm) was observed in Khed Shiravali genotype. Petiole girth (7.13 cm) was highest in Sree Pallavi and lowest petiole girth (4.84 cm) was recorded in NDB-9 genotype. The maximum leaf area (747.29 cm²) was recorded in Khed Shirvali genotype and it was at par with Sree Pallavi (739.72 cm²) M-12-429 recorded minimum leaf area (464.06 cm²).
