Phyto-toxicity of Alternanthera species on Germination of Zea mays (Maize) Crop
Alternanthera species is regarded harmful weed. It belongs to family Amaranthaceae. Phytotoxicity involves both inhibitory and biochemical interactions between plants. Alternanthera species toxic effect studies have been done on crops such as Baby corn (Zea mays) in laboratory conditions to determine their phytotoxic potential and its use. In the present study phytotoxic effect of leaf extract (2%, 6% and 10%) of Alternanthera species on percent seed germination of Zea mays crop was studied. it was found that among Zea mays was most affected with zero percent seed germination with 6% and 10% of the Leaf extract. Maximum percent of seed germination (0%) was recorded with Zea mays at 10%. Alternanthera leaf extract was found toxic to Maize seeds at 6% and 10% respectively.
