Abstract:
The research experiment was conducted in the Department of Horticulture, RCSM College of Agriculture, Kolhapur during winter 2018. Six promising varieties of Knol-khol viz., KSP-5311, Giant, Early white Vienna, Videshi EWV, Neo and Local were evaluated in factorial randomized block design with three replications for the varietal performance under greenhouse condition and open field condition to explore the possibility of cultivation of Knol-khol in sub-mountain zone of Maharashtra. The results regarding days required for germination and percent germination was found non-significant as all the conditions had no variation for these characters. The earliest germination was found in greenhouse condition for the cultivar Giant (5.33 days) and late germination found in open field condition for Local cultivar (7.67 days). The earliest 50% germination (8.33 days) was found in cv. KSP-531 and Giant in greenhouse condition. The maximum percent of germination was noticed in Greenhouse for Giant (92%) and (83%) for Early white Vienna in open field condition. Maximum plant height 28.94 cm and 23.98cm was found for the cultivar Giant inside greenhouse and open field condition respectively. Minimum stalk length 22.03 cm and 26.89 cm was observed under open field condition and greenhouse condition respectively in the cv. Early white Vienna. Mean plant height in open field condition (23.15 cm) was lower than greenhouse condition (27.60 cm). Maximum number of leaves was observed in cv. Giant (11.67) followed by KSP-5311(10.67), Videshi EWV and local (10.33), Early white Vienna (10.00) and Neo (9.67) in greenhouse condition. Mean number of leaves inside greenhouse was 10.44 and that in open field were 9.00. The maximum leaf length was observed in both conditions in hybrid Giant for greenhouse was 29.33 cm and for Open field 24.67 cm. Mean leaf length inside greenhouse (27.39 cm) was higher than open field (24.00 cm) condition.
