Cadmium Induced Changes in Growth and Biochemical Contents of Tomato <i>(Lycopersicon esculentum </i>L<i>.)</i>

The effects of different concentrations (10,20,30,40 and 50 ppm) of cadmium chloride on seed germination, root length, shoot length, fresh weight, photosynthetic pigments, protein content and peroxidase activity in tomato (Lycopersiconesculentum L.). Higher concentration of Cadmium were reported specially at 40 and 50 μm reduced germination significantly. Leaf chlorosis, wilting and leaf abscission were observed in plants with cadmium. Protein content and sugar content were reduced in higher concentrations of cadmium. However, lower concentrations of CdCl2 resulted in higher peroxidase activity in roots and shoots of tomato.

Response of Fenu-Greek (<i>Trigonella foenum-graecum</i> L.) to Rhizobium Inoculation

Green revolution increased the food production enormously to feed the geometrically growing population. In India, the availability and affordability of fossil fuel based chemical fertilizers at the farm level have been ensured only through imports and subsidies. Dependence on chemical fertilizers for future agricultural growth would mean further loss in soil quality. The possibilities of water contamination and unsustainable burden of the fiscal system. The Government of India has been trying to promote an improved practice involving use of biofertilizers along with fertilizers. These inputs have multiple beneficial impacts on the soil and can be relatively cheap and convenient for use. The agricultural chemicals like pesticide and weedicides were being used to save the standing crop from the attack of pests and to boost crop production. At the same time the excess use of chemical fertilizers degraded the soil properties. In this context, the farmers are expecting for the cheapest and eco-friendly alternative for getting higher yield. Biofertilizers is only the alternative way to get more production without harmful to environment. So the effect of different doses of biofertilizer (Rhizobium) on germination studies of Fenu-greek seed germination percentage, seedling growth, fresh weight and dry weight, chlorophyll, protein and soluble sugar content has been studied in the laboratory condition. There parameters increased to application when biofertilizer compared to control.

Allelopathic effect of <i>Azadirachta indica</i> L. on the germination of <i>Abelmoschus esculentus</i> L

The chemical compounds have been reported to be exuded by plants and their inhibitory effects of other plants. The research work was carried out to study the allelopathic effect of root, bark and leaf extracts of Azadirachta indica L. on the seed germination of Abelmoschus esculentus L. Germination studies were conducted in laboratory, the bhendi seeds treated with the root, bark and leaf extracts of Neem. On the seventh day the morphological parameters, photosynthetic pigment and biochemical contents were analysed. The result showed that the rate of germination of bhendi decreased in all Azadirachta indica L. extracts. The reduction in biochemical contents of bhendi was also noted. The highest rate of germination was observed in control (distilled water) treatment and the highest rate of inhibition was observed in root extract followed by bark and leaf extracts.
