Abstract: Direct drilling of wheat in to rice stubbles through zero tillage drill has eliminated the time for land preparation and improved crop stand establishment. In rice-wheat area, the adoption of zero-tillage is growing with the passage of time. The study was performed in Kala Shaha Kaku and Muridkay during 1998-99 to determine the optimum time for first irrigation and nitrogen application in zero tillage wheat in rice-wheat area of Punjab. In the first trial, the treatments included first irrigation at sowing, at emergence, two weeks after emergence and four weeks after emergence. In the second trial, treatments included all nitrogen dressed at sowing, half nitrogen dressed at sowing and half at first irrigation and all nitrogen broadcasted at first irrigation and all nitrogen broadcasted at sowing. The results indicated that emergence, tillering, grain and biological yield was significantly higher when the first irrigation was applied 2 to 4 weeks after emergence. Timing of nitrogen application did not significantly affect the heads per m2, grain yield and biological yield of zero tillage wheat. However, the split application of urea at planting and at first irrigation could improve zero tillage wheat production.
