Abstract

Many plants are known for their phytotoxic potential. Such plants tend to suppress the germination and normal growth processes in other plants under their effect. Calotropis procera is one of the most dominant weed plants in Pakistan and is largely known for its insecticidal, pharmacological and phytotoxic properties. It is found abundantly around and inside the agricultural field crops. This study was aimed at investigating the allelepathic effects of C. procera on Triticum aestivm (wheat) which is one of the most important agricultural crops in most of the Asian countries. The allelopathic effects were gauged using different indices for germination behavior and seedling growth. Results indicated that C. procera leaf extracts has such allelopathic compounds which can significantly reduce the germination of and seedling vigor of Triticum aestivum.
