A weed is defined as a plant of its proper place or where it is not required. A weed has more potential than the crop, compete with the crop, seed formation and distribution is before the seed and fruit production from the crop.  Cotton field infested with Cynodon dactylon and other weeds Here are the few characteristics which must be present in any plant to call them infestation and problematic for the crop (because there are some cropping systems such as relay cropping and intercropping where 2,3 crops are in the same field.) IDEAL CHARACTERISTICS OF WEED 1. They have ability to grow well under many environmental conditions. 2. Rapid growth rate both in vegetative and flowering stage. 3. Cross-pollination is very common which enable new genetic recombination better suited to the environment. 4. The seed production continues till the condition remains favorable. 5. Self-compatibility but not complete autogamy or apomixy. 6. Greater longevity of the seeds. 7. Discontinuous germi...

Weeds not only cause problems in our agricultural fields, but they also make the life troublesome for the common man, infesting the home gardens, health issues like allergies due to pollen, polluting the water bodies and so on. The following article is in the continuation of weed science and we will see the troubles caused by weeds. A gardener using sword to eradicate weeds from fallow land 1. Lower Crop Yields Weeds in the agricultural fields provide competition to the crop plants in a number of ways, for example, for nutrients, light, water and allelopathic compounds. This reduces the crop growth and yields. Management of these weeds is an expensive but necessary part of modern day agriculture; hence increasing the cost of production. 2. Lower Animal/ Livestock Yields Livestock yields are also reduced due to weeds. The presence of weeds in the agricultural land reduces fodder crops or range forage additionally presence of poisonous weeds may can health hazards, reduced growth of an...
