Abstract:
An experiment entitled “Growth parameter and Pest incidences of Chinese cabbage as influenced by different growing conditions and hybrid varieties” was conducted in five different growing conditions viz., 3 different shade nets (35%, 50% and 75%) shade intensity, polyhouse and open condition. Two hybrid varieties viz., Sun-60 & Tropical Highland were used for the experimental research in the season of Rabi 2020-21. The experiment was laid out in split plot design with ten treatment combinations and four replications. The results indicated that among the different growing conditions, polyhouse condition (G₄) recorded maximum number of leaves (20.92) and plant height (34.98 cm) at harvest. While leaf length (34.04 cm) and leaf width (22.96 cm) were at par with G₂ (50% shade intensity), (31.92 cm and 21.39 cm) respectively at harvest. Whereas open condition recorded minimum number of leaves, leaf length, leaf width and plant height (15.06, 26.42 cm, 17.73 cm and 28.16 cm respectively) at harvest. Similarly, among two hybrid varieties V₂ (Tropical Highland) recorded maximum number of leaves, leaf length, leaf width and plant height (17.20, 30.75 cm, 17.29 cm and 31.53 cm respectively) at harvest. When it comes to pest incidence (%), the lowest aphid incidence (4.81%) and caterpillar incidence (9.06%) was recorded in polyhouse while, the highest incidence was found in open condition (17.44% and 27.35%) respectively. Similarly, among the hybrid varieties V₂ (Tropical Highland) recorded the lowest aphid and caterpillar incidence (11.28% and 19.13%) respectively. While V₁ (Sun-60) recorded maximum aphid and caterpillar incidence (11.99% & 20.16%) respectively.
