Synthesis of Silver nano particles using different medicinal plant extracts and its characterization.

Abstract

      The environmentally nontoxic, ecofriendly and cost-effective method that has been developed for the synthesis of silver nanoparticles using plant extracts creates the major research interest in the field of nanotechnology. The synthesized silver nanoparticles have been characterized by the UV-VIS spectroscopy, X-ray Diffraction, Atomic force microscopy. Silver nanoparticles exhibit a broad spectrum of anti-bactericidal and anti-fungicidal activities making them extremely popular in a diverse range of consumer products including plastics, soaps, pastes, food and textiles thus increasing their market value. The presence of soluble organics in the plant extracts was mainly responsible for the silver ions reduction to Nano-sized silver particles. Thus it provides information on silver nanoparticles synthesis from various medicinal plants, various methods of characterization and its biological application.

Stimulate effects of Ground nut haulm compost, farm yard manures and bio fertilizers on growth of Ground nut (Arachis hypogaea L.)

Abstract
Ground nut is an important food legumes and oilseed crop in the world. The present research work deals with the effect of Stimulate effects of ground nut haulm compost, bio fertilizers and farm yard manures on growth of ground nut (Arachis hypogaea l.).the field experiment was conducted in the randomized block design with similar environmental condition. The treatment such as T1-control, T2 -1 tonne ha-1 haulm compost only,T3-1 tonnes ha-1 haulm compost + fym,T4-1 tonne ha-1 haulm compost + rhizobium,T5-1 tonnes ha-1 haulm compost + phosphobacteria and T6 – T2+ T3+ T4+ T5 alone. Field experimental season such as experimental period-January 2014 to May 2015, variety- vri 3,experimental design viz., split plot design and the plot size:2.5  2.5 m2. The treatments were allowed in ground nut haulm compost bio fertilizers viz., FYM, Rhizobium, phosphobacteria were treated in similar environmental conditions. The sampling period such as 20, 40 and 60 das respectively. The morphological parameter viz., root length, shoot length, leaf length, leaf area, leaf width, plant height, fresh weight, and dry weight, were measured. The bio chemicals such as total chlorophyll, carbohydrates, and protein contents were measured in various sampling days. The highest growth was measured in treatment six when compared with control.

INFLUENCE OF BIOFERTILIZER, INORGANIC FERTILIZERS AND ORGANIC FERTILIZERS ON GROWTH OF BLACK GRAM (VIGNA MUNGO L.)

ABSTRACT
Biofertilizers are natural and organic products. They help to provide and keep the soil with all the minerals and microorganisms required for plant growth. Their application is easy, cost effective and does not cause any pollution problem. In India, biofertilizers constitute the best renewable source of nutrient supply to plants and as supplement to chemical fertilizers and organic manures. The comparative effects on FYM, Inorganic fertilizers and Biofertilizers on growth ofblack gram (Vigna mungo L.) were studied.The thirteen treatements were studied under this experiments. The highest growth was recorded in combined application of biofertilizers alone. The inorganic fertilizers and organic manures are gradually increased in growth, and biochemical contents.Hence the use of biofertilizers should be encouraged.

EFFECT OF BIOFERTILIZERS ON NITROGENASE ACTIVITIES OF BLACK GRAM (VIGNA MUNGO (L.)Hepper.)VAR. ADT-3

Abstract
Biofertilizers have some micro organisms which convert elements to available nutrients for plant roots. This study was conducted to investigate the effects of biofertilizers chemical fertilizers and organic fertilizers on nodulation effects of biofertilizers. This trial was carried out randomized block design with three replicates t allowed to grow in similar environmental conditions.The treatement such as N,P, and K biofertilizers, N,P, and K inorganic fertilizers,and FYM,CCP and Vermicompost are single and in combinations were allowed treat in thirteen treatements. The nitrogenase activities were abserved in various sampling days. The highest growth was recorded in combined application of biofertilizers treatements when compared with control.

Petrography and Geochemistry of Dolerite Dykes at Gingee Area, Villupuram District, Tamilnadu, India

Abstract
Dykes intrusives of the Gingee area, Villupuram district, Tamilnadu, South India are chiefly composed of the clusters of mafic dykes found emplaced crisscrossing the entire district. They represent a significant phase of basic magmatism in the Southern Granlitic Terrain (SGT), which forms the Precambrian crust of the Southern Indian shield. Precambrian crust of the Earth constitutes nine cratons, namely regions in Asia and Indian subcontinent, Europe, Greenland, North America, South America, Africa, Australia and Antarctica. In this study reveals on dolerites in Gingee area based on petrography and geochemical analyzes. Petrography of the samples relects on ophitic to sub ophitic texture. IUGS classification shows basaltic nature.

Amphibian Activity Influenced by Water and Temperature of Agro Ecosystem in Nagapattinam District

Abstract
As a group amphibians are the vertebrates most affected by anthropic activity water temperature, particularly by agriculture & non agriculture pond, grass land. The rapid advance of the agricultural frontier makes it important to identify the role of agro ecosystems as habitat supply for amphibians. Climate and agriculture are interrelated processes and both of which take place on a global scale. The relationship is four sided. Climate will affect agriculture through rainfall, temperature, activity and other conditions. Since some plants need specific conditions to grow. Nagapattinam district has been choose for the study and it has plain topography. The study area has tropical climate and it is suitable for agriculture. The rainfall is received during the North East monsoon and low rainfall from South west monsoon. The district is predominantly an agricultural region which lies in the Eastern part of Cauvery delta and it is called the Rice Bowl of Tamil Nadu. The present study area lies between. The Nagapattinam district lies on the east coast of the south Cuddalore district and another part of the Nagapattinam district lies to the south of Karaikkal and Tiruvarur districts. It is bordered by the Bay of Bengal. The district lies between 10°25’ and 11°40’ North Longitude and 76°49’ and 80° The climate and its impact on agriculture is analyzed based on the data collected and accordingly the study area and relevant maps for this study were prepared using Geographical information system.
