Abstract The growth and herbage yield performance of sixteen colocasia (Colocasia esculenta L.) genotypes was evaluated at Central Experiment Station, Wakawali during kharif season of the year, 2016. The genot ypes exhibited highly significant variation for all the growth characters except days to first leaf emergence. The variation studied indicated that the growth characters, viz, the plant height (60.34 cm) and petiole length (57.55 cm) were recorded maximum in AC-20 genotype. The genotype Sree Pallavi showed maximum leaf length (55.86 cm), leaf breadth (42.50 cm) and petiole girth (7.13 cm). Whereas, leaf thickness, leaf area and number of leaves per plant were significantly higher in Mahim (0.538 mm), Khed Shiravali (747.29 cm2) and M-9-111 (17.47 plant−1) genotypes, respectively. The genotype M-9111 found to be the best genotypes for herbage yield in terms of per plant (276.93 g), per plot (2.49 kg) and per ha (10.26 ton) followed by Sanjivini and Sree Pallavi. Whereas, Devakibai Walanga produced lowest herbage yield per plant (158.57 g), per plot (1.43 kg) and per ha (5.87 ton). Top Keywords Colocasia, Growth parameters, Herbage yield. Top |
