Characterization of Rhizobium strain isolated from the roots of Glycine max (Soybean) (Aprana Alia) CLICK HERE TO ABSTRACT
Glycine max (Soybean) is a species of legume native to East Asia, widely grown for its edible bean which has numerous uses. The plant is classed as an oilseed rather than a pulse by the Food and Agricultural Organization. It is known for its dietary protein source, and symbiotic nitrogen fixation by Rhizobium present in its root nodules. The present study describes the characterization of a Rhizobium strain isolated from root nodules of Soybean. The Rhizobium isolates were rod shaped, gram negative, acid and mucous producing. They were found to be pH sensitive, with optimum values of 7.0°C. The bacteria was sensitive to the antibiotics streptomycin.

Comparative phytochemical evaluation and antimicrobial properties of Pleurotus ostreatus (Manisha Bhardwaj, Aprana Alia) CLICK HERE TO ABSTRACT
This study scientifically examined the photochemistry, antioxidant and antimicrobial potencies of two organic extracts of Pleurotus ostreatus. Generally, both extracts were effective against 89.8% of the isolates tested with Bacillus subtilis and Escherichia coli exhibiting highest gram ± ve and gram -ve susceptibilities by disc diffusion method, respectively. However, petroleum ether extract (PE) exhibited greater anti-gram negative bacterial activity than the acetone extract (AE) and further produced growth inhibition of these isolates in broth. Compared to PE, the acetone extract elicited higher total phenolic content and in vitro antioxidant capacity. Phytochemical analyses of the extracts revealed low to moderate levels of terpenoids, tannins, and carbohydrates, while alkaloids were not detected. The results indicate that P. ostreatus possesses antimicrobial.

Observations on the Physico-Chemical Status In Motia Lake of the Bhopal (Mahima Dixit , Aparna Alia) CLICK HERE TO ABSTRACT
The physio-chemical characteristics of Motia lake were monitored to determine the water quality of the lake. Samples were collected on monthly intervals from the lake. Physico-chemical parameters: temperature, pH, dissolved oxygen, alkalinity, water transparency and nutrients were measured simultaneously. Present investigation shows that status of the Motia Lake is eutrophic in nature.

Allelopathic effects of Datura stramonium on seed germination and seedling vigour of Triticum aestivum (variety GW 273). (Waseem Ahmad, Aparna Alia, Fatima Khan) CLICK HERE TO ABSTRACT
Wheat is cultivated worldwide as a cash crop, it produces a good yield per unit area, grows well in a temperate climate even with a moderately short growing season. Majority of India's population eat food stuffs made from wheat, moreover our country is the second largest wheat producer in the world. Datura stramonium is a naturally fast growing weed containing tropane alkaloids (atropine, hyosyamine, and scopolamine) and its presence has been sighted along the boundaries and hedges of the cultivating fields of wheat. The present study focuses on exploring the allelopathic interactions of Datura stramonuim on Triticum aestivum (variety GW273) seed germination and seedling vigour. Aerial parts of the plant Datura stramonium were dried in the oven at 80 degrees for 24 hours then crushed, mixed with distilled water and allowed to stand for 72 hours in water bath at 25 (±2) degrees followed by filtration using whatman's filter paper no.1.Four dilutions of different ratios were prepared for the ongoing study. The extracts pose significant and varying allelopathic effects on seed germination and seedling vigour of wheat.

Allelopathic effect of Calotropis gigantea on seed germination and seedling vigour of Triticum aestivum variety GW- 273. (Muzafar Akbar, Aprana Alia, Fatima Khan) CLICK HERE TO ABSTRACT
Calotropis gigantea weed belongs to Asclepiadaceae family,is a shrub growing on the wasteland and along the boundaries of wheat fields .It is world widely distributed but mostly abundant in tropical and sub-tropical countries .It contains the (alkaloids,falvanoids,glycosides ,uscharins) the present study is to evolving the allelopathic interaction of Calotropis gigantea on wheat (GW- 273) seed germination and seedling vigor. The wheat (GW-273) variety is obtained from wheat research station Gujarat agricultural university vijapur and is mainly cultivated in central zone (M.P). The whole aerial plant part of calotropis gigantea were collected ,washed ,dried ,crushed and diluted, different concentration of extraction were prepared ,the extraction effected on the seed germination and seedling vigour of the wheat.
