Abstract : Increasing water shortages has compelled to adopt the modern and efficient irrigation methods to enhance crop production. This research aimed to assess the performance of bubbler and basin irrigation methods in terms of water use efficiency, water saving and plant growth parameters of Sindhri and Chaunsa mango varieties. The plot area at experimental site in Sindh Agriculture University, Tandojam, Pakistan was divided into two equal parts, each one 889.87 m2 for bubbler and basin irrigation methods. Mango plants of both varieties of one year old were transplanted at 12.2 m spacing. The experiment consists complete Block design (RBC) with 2 treatments of 3 replications under each variety. ANOVA was done by applying Tukey test at p?0.05. The volume of water in both cases was applied as per crop water requirement. The performance of bubbler irrigation system was satisfactory for what it was designed in terms of distribution uniformity. The distribution uniformity varied by 92.6% for laterals and 93.9% for the entire system. The results revealed that about 30.94% water was saved under bubbler irrigation method as compared to the basin irrigation method. The additional amount of saved water can efficiently be utilized to bring the fallow land under cultivation.
