Research findings and their application in the field is a prerequisite for any improvement in quality and quality of agricultural products. The main objective of this research was to extend and adapt the research findings on salinity in wheat cultivated fields. Based on this, recommendations were made on various management practices including land preparation, irrigation methods and crop variety selection. Execution of these recommendations on a five hectare field for two consecutive years and comparison of the results with that of farmer’s field adjacent to the experimental field showed the following results:
In the first year wheat grain yield obtained from the experimental field was 4890 kg.ha-1. This was 9.6 percent higher than the yield obtained from the farmer’s field. Water productivity (WP) defined as the ratio of crop yield to applied water was 1.1 kg.m-3 in the experimental field showing an increase of 51.7 percents compared to WP calculated for the farmer’s field. In the second year, grain yield from the experimental field was 4870 kg.ha-1. This was 38 percent higher than the yield obtained from the farmer’s field. WP for the experimental field in this year was 0.91 kg.m-3. Considering the significant effect of the recommended practices on WP, it is proposed that the result of this project to be out scaled in fulfilling the objective of the 5th national development plant for increase in water productivity and irrigation efficiency.
