Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the latest advances concerning symbiotic relationships between plants and microbes, and their applications in plant productivity and agricultural sustainability. Symbiosis is a living phenomenon including dynamic variations in the genome, metabolism and signaling network, and adopting a multidirectional perspective on their interactions is required when studying symbiotic organisms. Although various plant-microbe symbiotic systems are covered in this book, it especially focuses on arbuscular mycorrhiza (AM) symbiosis and root nodule symbiosis, the two most prevalent systems. AM symbiosis involves the most extensive interaction between plants and microbes, in the context of phylogeny and ecology. As more than 90% of all known species of plants have the potential to form mycorrhizal associations, the productivity and species composition, as well as the diversity of natural ecosystems, are frequently dependent upon the presence and activity of mycorrhizas. In turn, root nodule symbiosis includes morphogenesis and is formed by communication between plants and nitrogen-fixing bacteria. The biotechnological application of plant–microbe symbiosis is expected to foster the production of agricultural and horticultural products while maintaining ecologically and economically sustainable production systems. Designed as a hands-on guide, this book offers an essential resource for researchers and students in the areas of agri-biotechnology, soil biology and fungal biology.

Download or read book Efficacy of Herbicides Under Direct Seeded Rice Establishments written by Mandhata Singh and published by LAP Lambert Academic Publishing. This book was released on 2011-12 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Change in method of crop establishment from traditional transplanting of seedlings to direct seeding has occurred in many rice growing countries in response to increasing production cost, especially for labour and water. It also aids in quick rice establishment, early harvest and thus early sowing of wheat. Sowing of pre-germinated rice seeds under puddled condition either manually or drum seeding method reduces the demand of water for puddling and minimized the emergence of weed flora by placing the seed, stems and stolens of weeds into sub-surface. Direct seeded rice is subjected to greater weed competition because both weed and crop seeds emerge at the same time and compete with each other from the germination as a result less grain yield. Uncontrolled weeds reduce the yield by 96 % in dry seeded rice and 61% in wet seeded rice. Control of weeds is important to reduce the weed competition as well as to maximize the efficient utilization of resources. Herbicides are considered to be an economical alternative to manage weeds against age-old practice of hand weeding, which is costlier and also becomes impracticable.
