Effect of leaf knotting practice in relation to source sink relationship on yield and quality traits in garlic (Allium sativum).

摘要

The impact of knotting of leaves 2 to 4 weeks before harvest on yield, quality and bulb storage life of garlic was investigated. Knotting of leaves was done 4 weeks before harvest in one set of garlic plants and 2 weeks before harvest in another set. The maximum benefits for all criteria were observed for plants knotted 2 weeks before harvest. This treatment increased the bulb fresh and dry weight and advanced maturity than control. Leaf fresh and dry weights were more in control plants. Knotting of leaves 2 weeks before harvest increased both polar and equatorial diameters. The treatment enhanced bulb yield in plants knotted 2 weeks before harvest. It also enhanced the carbohydrates, sulphur, ascorbic acids, carotenoids and anthocyanin pigment of the bulb, which enhanced its marketability. Garlic knotted 2 weeks before harvest showed maximum moisture loss during storage. There were no losses due to rotting or sprouting.
