POSSIBLE ALLELOPATHIC EFFECTS OF THREE DIFFERENT WEEDS ON GERMINATION AND GROWTH OF MAIZE (ZEA MAYS) CULTIVARS
NASIRA JABEEN AND MOINUDDIN AHMED
Abstract: The experiment was designed to determine the allelopathic effects of three different weeds viz., Onion weed (Asphodelus tenuifolius Cavase), pill-bearing spurge/Asthma plant (Euphorbia hirta Linn) and Fumitory (Fumaria indica Haussk H.N.) on the growth of maize. The weed powders toxicity and their inhibitory effects on germination and growth of maize crop were observed. It was demonstrated that different weed species responded differently to the maize. It was observed that the Asphodelus tenuifolius and Fumaria indica inhibited % germination and germination index of maize. The growth parameters of maize did not show consistent effects by these weeds. During the present study, allelopathic effects were not revealed and more experiments are suggested before making any conclusion about the allelopathic characteristic considering these weed species.
