Effect of Vermicomposted Vegetable and Fruit Wastes on the Vegetative and Yield Parameters of Lablab [Lablab Purpureus (L.) Sweet

Abstract

Background: Organic farming are degradation of organic materials and less use of chemical fertilizers and pesticides. Vermicomposting is the process of introducing earthworm species into the compost. It behaves as eco-friendly manure and gives good health to soil. Methods: The present study was conducted at Avinashilingam Institute for Home Science and Higher Education for Women, Coimbatore over a period of 3 months from March to May 2019. There are 8 treatments namely T1-T8 and control. The effect of incorporation of vegetable and fruit wastes biocompost on the vegetative parameters such as shoot length, root length, number of leaves, fresh weight and dry weight on 15, 35, 55 DAS and yield characters i.e. number of pods/plants, number of seeds/pods, pod length, weight of the seed, pod fresh weight and dry weight on 75 DAS in Lablab [Lablab purpureus (L.) Sweet] were analysed. Result: The results from study revealed that T8 treatment showed significant increase in shoot length (113.7, 124.5 and 135 cm), root length (13.2, 18.5 and 27 cm), number of leaves (22, 39 and 48), fresh weight (4.911, 15.693 and 21.244 g) and dry weight (0.652, 2.156 and 3.234 g) on 15, 35, 55 DAS and yield parameters such as number of pods/plants (40), number of seeds/pods (6), pod length (13 cm), weight of the seed (4.060 g), pod fresh weight (7.425 g) and dry weight (1.382 g) on 75 DAS in Lablab over control. The study concluded that T8 treatment is an effective manure which can be used to enhance plant growth, provide better yield which will be beneficial for farmers.
