Higher atmospheric CO2 concentration may influence positively plant production once the substrate for photosynthesis and gradient increase between the ambient air and mesophyll cells.
The present study was undertaken to know the effect of concentration of lead (Pb) and different organic materials on the maize yield, concentrations of lead on maize plants and diethylene triamine penta-acetic acid (DTPA) extractable lead (Pb) on the post harvested soils.
>> Researchers have unearthed the mummy of a 67-million-year-old hadrosaur from South Dakota in the US. A high-resolution CT scan of the 10-tonne fossil shows that the well-preserved body has much
