Role of Allelopathy in Irrigated Agriculture

  • Allelopathy is a well-known natural process in ecological systems. Since ancient times, it has been utilized in agriculture.
  • Allelochemicals have the potential to aid or prevent plant germination and development, allowing the growth of crops with low phytotoxic residue amounts in water and soil. This way allelopathy enables wastewater treatment and recycling.
  • Allelopathic chemicals can be seen as suitable alternatives for non-natural herbicides owing to their non-residual effects. However, despite their promising potential as natural herbicides, they suffer certain issues such as low efficacy and specificity of many allelochemicals.

Allelopathy and its Role in Agriculture

Allelopathy and its Role in Agriculture: Allelopathy is a biological phenomenon where certain plants release chemicals into the environment, affecting the growth and development of neighboring plants, either inhibiting or promoting their growth. Allelochemicals possess the capacity to either facilitate or hinder the germination and growth of plants, enabling the cultivation of crops with minimal phytotoxic residues in both water and soil.

In this article, you are going to read about Allelopathy and its Role in Agriculture, its pros, cons, etc.

What is Allelopathy?

It is a sub-domain of chemical ecology that deals with the impact of hazardous chemicals (called allelochemicals or allelochemicals) released by some plants to destroy the plants in their vicinity. These chemicals alter the genetic structure of the neighboring plants to cease their growth which is ultimately fatal for them. This phenomenon is common in plants as well as organisms. It can be observed in plant-plant interaction, plant-microbe interaction, and plant-animal interaction as well....

Why some Plants are Allelopathic?

Allelopathic plants release harmful chemicals to kill their competitor plants. It is a survival game. In doing so, allelopathic plants win the race to get more space and sunlight as well. Allelopathy is very common around us even more than we think. For example, the sunflower is also an allelopathic plant. After harvesting its crop, farmers need to wait for more than two weeks before going for the second crop in the same field in order to save the second crop from the allelopathic effect of the earlier crop....

Allelopathy in News

In 2014, it was pointed out by Himachal Pradesh (HP) Forest Department that a deadly weed “Lantana” which is also called “Phool Lakri” in the regional language has drastically affected the forest biodiversity in more than 1800 square kilometers. Lantana was brought to India in 1809 in the Indian Botanic Garden, Kolkata. It has beautiful flowers which enable it to be an ornamental plant. It flowers throughout the year. It spreads easily and exhibits extensive seed production. It poses serious problems to plantation forestry owing to its dominance over other species. It also acts as a potential fire hazard as it is combustible even in its green form. HP witnesses forest fires each summer season which causes great losses to the state and environment....
