Weeds are the main biological constraint to crop production throughout the year. Uncontrolled weeds could cause 100% yield loss. In Australia, the overall cost of weeds to Australian grain growers was estimated at AU$ 3.3 billion annually. In terms of yield losses, weeds amounted to 2.7 million tonnes of grains at a national level. In the USA, weeds cost US$ 33 billion in lost crop production annually. In India, these costs were estimated to be much higher (US$ 11 billion). These studies from different economies suggest that weeds cause substantial yield and economic loss. Biology and Management of Problematic Weed Species details the biology of key weed species, providing vital information on seed germination and production, as well as factors affecting weed growth. These species include Chenopodium album, Chloris truncata and C. virgate, Conyza bonariensis and C. canadensis, Cyperus rotundus, and many more. This information is crucial for researchers and growers to develop integrated weed management (IWM) strategies. Written by leading experts across the globe, this book is an essential read to plant biologists and ecologists, crop scientists, and students and researchers interested in weed science. - Provides detailed information on the biology of different key weed species - Covers weed seed germination and emergence - Presents the factors affecting weed growth and seed production

Dry-direct seeded rice (DSR) is an emerging resource-conserving and climate-smart production technologies in the changing climatic condition and the areas where the key resources such as water and labor are the major limiting factors to rice cultivation. The success of DSR largely depends on its proper early establishment and judicious weed management. A uniform stand of adequate rice plants is critical to achieving high yields, therefore seed rate and sowing date are very important for DSR. Due to different methods of land preparation between DSR and transplanted rice, the soil conditions are different in these systems, therefore, nitrogen fertilizer management is very important to DSR. Chemical weed management is a must in DSR to reduce weed management cost, however, considering the negative effect of herbicide on the environment and developing of herbicide resistance biotypes, weed management needs an integrated approach. Inside this book, you'll find the effect of sowing time and seeding rate for the establishment of DSR and the best fertilizer and weed management approaches for its sustainable production.
