Asian subtropics occupies 21 million hectares of rice-wheat cropping system on their fertile soils. This system carried out on 15 million hectares with highly significant impact for food safety in the area, providing staple food for more than 415 million people.Wheat (Triticum aestivum L.) has the highest position in food grains in Pakistan: 66% of the total area under food grains is wheat and it contributes 74% of the total food grain production.Tillage is done according to the soil types. Delay in wheat sowing is the result of 6-8 ploughing with planking and loss of high energy.Timely wheat planting after rice ensured in 10 percent higher wheat grain yield in a rice-wheat cropping system.Drilling of wheat in to rice residue using zero tillage has eliminated the time for land preparation and improved crop stand establishment.So,this study has, therefore, been planned to achieve the most economical method for sowing wheat in a rice-wheat cropping system and Quantify the nutrient losses to soil fertility of burning rice straw. Mushtaq Ahmad Gill is the founder of zero tillage and laser land leveling technology in Pakistan and contributed a lot for this research and book.
