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.
Background: Composting is the process of breaking down of organic matter using living organisms which can be used as manure for soil conditioning. Vermicomposting is the rapid decomposition of biowastes using earthworm species which will enhance the growth and yield of plants. Methods: The vermicomposting of vegetable and fruit wastes was carried out during summer season (May-July) and by using the vermicompost a pot culture experiment was conducted in black gram for three months from August to October, 2019. The treatments consist of combinations of vermicomposted wastes and cowdung along with bioinoculants, Soil served as control. The biometric parameters such as root length, shoot length, fresh weight and dry weight on 15, 35, 55 DAS and yield characters like number of pods/plants, number of seeds/pods, pod length, weight of seed/pod, pod fresh weight and pod dry weight were recorded and statistically analysed. The present study has been attempted to convert the vegetables and fruit waste into compost as manure and analyse its effect on vegetative growth and yield parameters of Black gram (Vigna mungo L.). Result: The highest value of shoot length, root length, fresh weigh and dry weight were noted in fruit waste + cow dung + Pleurotus eous (APK1) + Trichoderma asperelloides + Eudrilus eugeniae on 15, 35 and 55 day after sowing (DAS) and the least was reported in control (only soil). The application of T8 treatment reported the highest yield characters which were followed by other treatments and control on 15, 35 and 55 DAS. The study concluded that T8 (F.W + cow dung + P. eous + T. asperelloides + Eudrilus eugeniae) is an effective biocompost for the growth and yield of black gram (Vigna mungo L.) which is eco-friendly.
Background: Amidst of emerging world with the new technologies we are in the dangerous condition regarding the disposal of agro industrial wastes which creates a serious problem. Organic manures can prevent and can enhance the productivity in the plants as well as can reduce the environmental issues. Methods: The study was conducted in the month of September to November 2019 at St. Joseph’s College Campus, Visakhapatnam, A.P. with the bio composting process of paddy and coffee husk along with Pleurotus eous, Pleurotus florida, Trichoderma asperelloides and Eisenia fetida, with 6 treatments. The plants were analyzed for root length, shoot length, number of leaves, number of nodules, fresh weight and dry weight of the plant on 20, 40 and 60 DAS and the yield parameters were analyzed on 90th day of the plant. Result: The results showed a great increase in the treatment 6 (Pre decomposed coffee husk, consortium of Pleurotus eous, P. florida, Trichoderma asperelloides and Eisenia fetida) in root length (8.5, 12.9 and 16.1 cm) shoot length (15.2, 30.3 and 43.2 cm) number of leaves (11, 18 and 49) number of nodules (12, 20 and 9) fresh weight (4.83, 8.98 and 15.47 g) and dry weight (1.11, 3.56 and 4.37 g) when compared with the other treatments and control. The yield parameters also showed significant results in number of pods (27), length of the pod (5.7 cm), number of seeds/pod (6), weight of the seeds/pod (2.89 g), fresh weight of the pod (1.653 g) and dry weight of the pod (0.986 g).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
