Allelopathic effects of Parthenium hysterophorus were studied on seed germination and seedling growth of Triticum aestivum, Oryza sativa, Glycine max and Cajanus cajan. The shade dried leaves of Parthenium hysterophorus were soaked in distilled water for 24 hours at room temperature to obtain aqueous extract and sterilized seeds were treated with 2%, 4%, 6%, 8% and 10% concentration of P. hysterophorus leaves aqueous extract. The germinated seeds were counted every day to observe mean germination time. It has been found that significant time is taken to germinate with increasing concentration. It has been also observed that germination percentage, root length, shoot length and seedling vigour value were reduced at >2% as compared to control. The 10 % aqueous extract showed the maximum inhibitory effect on seedling growth. In the present investigation, the leaves aqueous extract of P. hysterophorus had strong inhibiting effects on seed germination and seedling growth. It is necessary to keep this weed under check at the emerging stage at agro crop field so that crop growth constraint may be avoided

The present study aims to identifying seed borne fungi associated with different legumes plants. The seeds of Macrotyloma uniflorum, Vigna radiata, Vigna mungo, Vigna unguiculata, Arachis hypogea, Phaseolus vulgaris, Cicer arietinum, and Glycine max were collected from local market of Hudco, Bhilai. Treated and untreated seeds were used for the screening of seed borne fungi using agar plate method. The untreated seeds were found to be associated with highest number of fungi, while treated seed shows least number of fungi. The fungi isolated from these seeds were Aspergillus niger, A. flavus, A. fumigatus, A. nidulans, Alternaria alternata, Rhizopus sp.1, Rhizopus sp.2, Penicillium sp., Mucor sp., Fusarim sp., Macrophomina sp. and Curvularia sp.

India is rich in medicinal plant diversity, which is distributed in different geographical, environmental conditions and associated tribal and folk knowledge systems. The field study was carried out during November 18, 2015 to December 02, 2015 on the Campus of Pt. Ravishankar Shukla University, Raipur (Chhattisgarh.). A total 78 plant species belongs to 72 genera and 35 families were collected from the study area. All the plant species were identified and their ethnobotanical information was elucidated. Out of 35 families, 02 were monocotyledons (Poaceae and Liliaceae) and the remaining belongs to dicotyledons.
