List of top Agronomy Questions on Weed-Crop Competition and Allelopathy

Given below are two statements:
Statement (I): The combined effect of competition and allelopathy where growth of weeds or crop or both is reduced is called allelomediation.
Statement (II): Allelopathy depends on addition of chemical compounds while competition involves removal of an essential factor from the environment.
In light of the above statements, choose the most appropriate answer from the options given below.
Statement I: C3 weeds such as Avena fatua, Phalaris minor and Chenopodium album are generally more competitive than C4 weeds especially at higher temperature conditions.
Statement II: In C4 weeds photosynthesis occurs via the Calvin-Benson Cycle and the first stable product is phosphoglyceric acid.
In light of the above statements, choose the correct answer from the options given below:
Statement I: Due to lack of mobility the competition between crop and weeds is active being visible in the beginning.
Statement II: A good competitor could be the species with least resource requirement.
