The present work phytoconstituents of the seed powder of Sterculia foetidaL. extracted with 98% methanol. The extracted phytochemical compound subjected to qualitative analysis, quantitative analysis, fluorescence analysis and GC-MS analysis. The results of qualitative phytochemical screening confirm that the presence of tannins, phenols, steroids, cardiac glycoside and coumarin. The significant amount of carbohydrate, protein, lipid, tannin and total phenol estimated through quantitative analysis of phytochemicals. The seed powder with the picric acid exhibited fluorescent yellow during fluorescence analysis undertaken with short ultra violet light at 254 nm. There are 13 bioactive compounds were identified through GC-MS analysis of seed powder of S. foetida L. These various bioactive compounds possess a wide range of activities such as disease control, pest control and microbicidal effect.

Soil is the main source of supplying essential nutrients for plant growth. In agricultural practice, when a particular nutrient or a group of nutrients are absent in the soil, it may affect the growth of the plant. Thus, most of the farmers practicing to apply chemical fertilizers to overcome the soil nutrient deficiency. Chemical fertilizers enhance the soil fertility on one hand whereas on the other hand it cause environmental pollution. Therefore alternative methods of soil nutrition practice must be considered. Hence this work focused to prepare fermented liquid fertilizer to enhance the plant growth. In the present study the fermented liquid fertilizer was prepared by fermenting the Portunussanguinolentus (Herbst, 1783) crab wastes with jaggery. After 15 days, the fermented liquid from crab waste was filtered and used for further study. The harvested liquid subjected to physico chemical and microbial analysis. The functional group and active compounds present in the fermented liquid was analyzed through FT-IR and GC-MS study. Phytotoxicity of the fermented liquid was determined through seed germination assay by using TMV-7 ground nut seeds. The result showed that the fermented liquid was diluted in water in the ratio of 1:100 exhibited higher seed germination when compared to other test dilutions and control. Thus the present work strongly supports the view that the traditionally fermented crab waste liquid contain high nutrients and active compounds and that may support the ground nut plant growth.
