ELEVATION OF WHEAT CULTIVARS AT VARIOUS LEVELS OF NITROGEN THROUGH FIELD EXPERIMENTATION AND MODELING APPROACH IN PUNJAB, PAKISTAN

Abstract

The present study was conducted to evaluate the growth of wheat cultivars at different nitrogen (N) levels through experimental and crop simulation model in Sialkot District of Punjab, Pakistan. The data was collected from the fields as well as the weather and soil data obtained from the relevant departments. The experiment was conducted for two wheat cultivars with four treatments of N i.e. 0, 55, 110, 220 kg N per hector. Overall, the results indicated that the field level observed data showed significantly positive correlation with the model simulated growth and yield variables. The findings of this study showed that out of the two wheat cultivars i.e. Faisalabad-2008 showed earlier anthesis and maturity as compared to the Sehar-2006, however, the wheat yield, leaf area index, and harvest index was higher for Sehar-2006. From these results, it can be concluded that Sehar-2006 has more productivity and must be encouraged as compared to Faisalabad-2008.
