Lentil (Lens culinaris M.) is a nutritious food legume and is the fourth most important pulse crop in the world.Lentil seed is a rich source of protein, minerals and vitamins for human nutrition and the straw is a valued animal feed. The legumes secrete flavonoids which attract motile rhizobia that attach to the root surface. These bacteria when come in contact with legume roots enhance its growth in a number of ways.Thus integrated use of plant growth promoting rhizobacteria and value-added composted organic waste could be highly effective in improving yield and nodulation of lentil crop.A field study was planned to investigate the integrated effect of plant growth promoting bacteria containing ACC-deaminase, rhizobia and enriched compost on growth, nodulation and yield of lentil. This book provides a vital piece of knowledge for upcoming researchers in field of plant microbiology and nutrition.

This book explores the long-term ageing effects at 475 C on the microstructure and properties of Custom 465(R) alloy. It covers the theoretical aspects of precipitation-hardened stainless steels, including the formation of reverted austenite and its impact on mechanical properties, along with the 475 C embrittlement process in Fe-Cr steels. Experimental findings using TEM and XRD show that proper heat treatment leads to the precipitation of η-Ni3Ti particles and a small amount of reverted austenite in tempered lath martensite. Extended ageing at 475 C for 1000 and 2000 hours results in further precipitation and an increase in reverted austenite, which helps mitigate the hardening effect of the α -Cr rich phase. The study demonstrates that while strength decreases with prolonged ageing, elongation and impact energy remain largely unaffected.
