EXTENT OF CORRELATION COEFFICIENT BETWEEN YIELD AND ITS CONTRIBUTING TRAITS IN ONION (ALLIUM CEPA L.) UNDER DHAMPUR (BIJNOR) CONDITION

摘要

The experiment was conducted at Horticulture Research Farm of RSM PG, College, Dhampur, Bijnor (UP), during winter season 2019-2020. The onion variety Agrifound Light Red was used for the study. The periodical observations on growth yield and yield attributes was recorded to find out the correlation coefficient of different growth and its attributing characters. Plant height showed, positive and highly significant correlations with Diameter of stem (0.766), Fresh Bulb weight (0.828), Dry Bulb weight(0.913), and per plant equal diameter (0.804). Number of leaves/plant showed positive ari'd highly significant correlations with Total soluble sugar (0.802). Height of leaves/plant showed positive and highly significant correlations with Height of stem (0.951). Height of stem/plant showed positive and highly significant correlations with protein (0.918). Diameter of stem /plant showed positive and highly significant correlations with fresh bulb weight (0.932). Fresh bulb/plant weight showed positive andhighly significant correlations with dry bulb weight (0.978). Dry bulb weight showed positive and highly significant correlations with, protein (0.943). Polar diameter showed positive and highly significant correlations with, protein (0.845). Equal diameter showed positive and highly significant correlations with Protein (0.817).Yield /plot showed positive correlations with yield/hectare (1.000).Yield/hectare showed positive correlations withT.S.S (0.401).
