Huge losses in wheat yield are attributed to the invasion of various diseases, out of which, rusts, especially stripe rust has caused enormous yield losses in the recent years. Until now, P. striiformis has been controlled partly by growing genetically resistant cultivars and partly by spraying wheat crop with fungicides. However, the option of using fungicides may become even less favourable in the future as a result of restrictions in their use. Consequently, various methods like gene pyramiding, multillines, multivar and gene deployment, were proposed as a means of using race-specific...

The concept of reduced or zero tillage systems is not new. Many developed and developing countries also use these systems, which are often found to generate higher yields, reduce production costs and reduce erosion and other forms of land degradation, with corresponding benefits for the natural resource. A whole system of mechanization has been developed in these countries to ensure good crop establishment, proper placement of fertilizer and handling of crop residues for better yield. These equipments are accompanied by a set of recommended crop management and protection for handling weed,...
