Abstract
The present study was planned to describe the allelopathic effect of Euphorbia hirta (Pig weed) on Cicer arietinum (black gram) The effect of weed extract and powder on different growth parameters were studied on seed germination, velocity of germination, seedling growth, plant height, fresh and dry weight, chlorophyll and protein contents of Cicer arietinum. In Petri plate experiments extract of different concentrations were used such as 3, 5 and 7 % and distilled water used as a control with their five replicates. The 7 % extract of E. hirta showed highest inhibitory effect on germination, velocity of germination, seedling growth and plumule length was more inhibited than the radicle length of test crop. In Pot experiments weed powder were taken in different amount such as 10, 15 and 20 g, mixed with uniform amount of soil (500 g) and control pots were filled only with soil, with their five replicates. Weed powder has non-significant effect on plant height of C. arietinum. Fresh and dry weight also indicates inhibitory effect was proportional to the amount of weed powder. Chlorophyll contents and carotene were gradually decreased in treated plants as compared to the control. The highest % inhibition was observed in 20g. The inhibition may be due to the allelochemicals present in E. hirta.
