Studies on agrestal diversity in the sugarcane field of Howrah district, West Bengal, India: use as an important bioresource for human welfare

  Agrestals are small plants (weeds) in the agricultural field which have had a huge impact on agriculture through the ages, and they continue to effect agricultural practices today. Generally, weeds are plants said to grow where they are not wanted. They compete with crops for water, nutrients, light and space thus reduce crop yields, but not all weeds are undesirable. In many systems, weeds are useful...
