In the northeast, a series of publications on the life his-tory of several weed species, including nutsedge, was pub Weeds add about 5 to 15 tonnes of green matter per hectare depending upon weed species and their growth. The environment includes climatic, edaphic and biotic factors and it determines the distribution, prevalence, competing ability, behavior and survival of the weeds. Weed ecology is thus concerned with growth characteristics and adaptations that enable weeds to survive changes in the environment.

They release oxygen into the atmosphere, absorb carbon dioxide, provide habitat and food for wildlife and humans, and regulate the water cycle. Nutrient contents of some weeds are given below: Gokhru (Xanthium strumarium) – 3 to 3.5 % N Bavachi ( Psoralea corylifolia)  – 3 to 3.5 % N Leguminous weeds – 1.5 to 6 % N. 2) Weeds Check Wind, Water and Soil Erosion: Weeds growing on desert lands, waste lands and sloppy fields lower wind and water erosion and also help for protection of the environment. of Weeds and Their Impact on the Environment Weeds and invasive plants impact the world around us and our daily lives. The important climatic factors are light, temperature, rainfall, wind & humidity. stream Weeds can also prevent pest insects from finding a crop, because their presence disrupts the incidence of positive cues which pests use Mathur SM, Mathur P (2006) Aquatic weeds and its impact on environment with special reference to water hyacinth. Weeds compete with native plants for light, moisture and nutrients and don’t provide ideal food and shelter for native wildlife. The importance of fisheries and aquaculture to development 355 and canoes, and collecting seaweed, bivalves, molluscs and pearls. An undeniable and expensive consequence of agricultural practices is the adaptation of weeds to agricultural systems. In aquaculture, women feed They can reduce crop yields, choke waterways, trigger allergies, disrupt the natural habitats of plants and Overgrown weeds make our environment bushy and dirty. Roots of weeds tap nutrients from the lower soil depths and return these to the soil surface as litter when the weeds shed their leaves or when the entire plant plants dies and decays. They reduce farm and forest productivity, displace native species and contribute significantly to land and water degradation. Weeds can perform vital ecosystem services such as protecting and restoring exposed or degraded soils. In addition, some weeds provide habitat for beneficial organisms, and thereby contribute significantly to natural and biological control of some insect pests. })(); Farming Systems & Sustainable Agriculture, Breeding of Field and Horticultural Crops agriculture information, Fundamentals to Entomology agriculture information, Production Techniques for Biological Control Agents, Practicals on Technology of Milk & Milk Products agriculture information, Economics of Natural Resources & Farm Management agriculture information.
