    Effectiveness of media approach on the academic achievement of class 8th Students in English
    (International Journal of applied Research, 2015) Kaur, Ranjit; Sharma, Kavita; Singh, Shamshir
    The aim of this paper was to find out the Effectiveness of Multimedia approach on the academic achievement of class 8th students in English. The sample consisted of class 8th students in English of Tagore Model School. The data was collected by using an appropriate tool and analyzed by‘t’ test. Pretest-posttest experimental control group design was followed for this study. Means, S.D.s and t-test were used to analyze the data. The multimedia package prepared by researcher for teaching English was found to be more effective for academic achievement of class 8th students in English.

    Utilization of vermi-incorporated feed for the seed production of two freshwater ornamental fish, Xiphophorus helleri and Poecilia sphenops
    (Springer Science and Business Media Deutschland GmbH, 2023-10-18T00:00:00) Sharma, Kavita; Garg, Vinod Kumar
    Integrated ornamental pisciculture and vermiculture is an eco-friendly cleaner technology of resource utilization contributing to the circular economy of a country. The present investigation studied the effect of earthworms, Eisenia fetida, on the seed production of ornamental fishes. Earthworms have a high crude protein and lipid content and are hence utilized as one ingredient for making fish feed, i.e., vermi-incorporated feed. Vermincorporated feed was prepared using different percentages of earthworm powder. Earthworms used for making fish feed were obtained from various vermicomposting experiments. Reproduction of swordtail, Xiphophorus helleri, and black molly, Poecilia sphenops, was assessed at different percentages of vermi-incorporated feed. The results revealed that maximum fry production was at 3% vermi-incorporated feed application in Xiphophorus helleri(293.7�22.7) as well as in Poecilia sphenops�(312.3�4.7). Minimum fry production was when fishes were fed with 1% vermi-incorporated feed. Female biomass was positively correlated (R 2=0.95-0.97) with the mean fry production in different treatments for both species. No mortality or deformities were observed during the experiment. Water quality parameters were in the optimal range for ornamental fish breeding. Results revealed that earthworm protein can be successfully used for the seed production of ornamental fish � 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

    Vermicomposting technology for organic waste management
    (Elsevier, 2022-09-16T00:00:00) Sharma, Kavita; Garg, V.K.
    Present chapter reports vermicomposting technology for the treatment of non-toxic biodegradable wastes. These wastes generated from domestic, commercial, agricultural and industrial activities. Several methods are used for the waste management but still huge quantities of organic wastes remain unattended which is a cause of concern. Therefore, scientific and sustainable interventions are needed for the management of organic wastes. Vermicomposting is one such technique which is economically viable and has manifold advantages over other non-scientific waste disposal techniques. Vermicomposting has been well addressed in recent years and several researchers have investigated the effectiveness of vermitechnology to treat organic wastes. Although organic wastes are heterogeneous in nature but its biodegradable nature offers an immense opportunity for vermicomposting. Combined action of earthworm and microbes mineralize organic waste and transformed it into manure that has potential to solve several soil fertility and pollution related issues. Vermicomposting can also potentially be used as a bioremediation technique. Use of vermicomposting for waste treatment and bioremediation on one hand ensure agricultural and environmental sustainability and on the other hand manure is provided. Earthworms, a product of vermicomposting, can be used as feed in aquaculture and poultry industry. � 2023 Elsevier Inc. All rights reserved.
