One of the promising approaches to enhance salt tolerance in crop plants is the proper use of plant growth regulators. The presented work is an effort to investigate the ameliorative role of 5-aminolevulinic acid (ALA) in oilseed rape plants grown under salinity conditions. Chapter 1 of this monograph is a brief introduction about oilseed rape (Brassica napus L.), salinity associated problems and strategies to tackle salinity as well as study s objectives. Chapter 2 highlights the previous studies and achievements regarding the salinity stress and its interference with the different...

Mulching with some organic materials like straw, hay, trashes, dry leaves, etc., have been used for many centuries as natural mulch, which acts as a physical barrier to limit soil water evaporation, to control weeds, to maintain a good soil structure and also to protect crops from soil contamination.Organic mulch if properly used can offer all the benefits of any mulch. However natural materials are not often available in adequate and require more labour for spreading. Organic mulches were reported to reduce soil temperature and evaporation, but did not increase the crop yield. The use of...
