Effect of Quarry Activities on Some Morphological Parameters of Two Maize Varieties (SWAN 1 and SAMMAZ 52)

The effect of quarry activities on some morphological parameters two maize varieties (swan 1 and sammaz 52) was investigated with the aim determining impact growth under study. seeds were collected from Seed Bank Department Ondo State Ministry Agriculture, Akure, State. They authenticated at Herbarium unit Federal University Technology, voucher deposited. Soil samples 50m, 100m, 150m, 200m, 250m site transferred to laboratory for analysis. A screen house experiment set up pots. Seeds SWAN SAMMAZ 52 sown into perforated plastic pots (30 cm diameter 33 depth) filled 10 kg soil. following determined; shoot height, leaf area, plant dry weight, root root-shoot ratio, determination photosynthetic especially chlorophylls a b. result revealed that 50 meters site, 52, one grown in soil taken had highest height (94 cm). which showed plants growing higher concentrations dust pollution respond nutrient stress by devoting more their available carbon growth, resulting elongated stems, consistent observed daily variations activity rate nitrogen uptake are blame these alterations behavior. efficiency use nutrients determines whether they will survive an area where there is dust. biomass (3.84g) 52's management regime can be attributed best possible rates photosynthesis assimilation, as well presence chlorophyll larger surfaces.
