Conclusion
Tuber extract of nutgrass, when applied to the growing medium, inhibited the germination and growth of 10 crop species under the laboratory conditions. On the basis of above findings, the presence of some phytotoxic substance(s), however, in nutgrass tubers has been confirmed. Although the germination and growth of all the crops, included in this experiment, was inhibited by the phytotoxins present in nutgrass tubers yet the degree of such inhibition varied with different crop species.
