Performance evaluation of surface irrigation method was carried out for cotton and wheat fields in village Kirarkot (Sirsa). Water application, storage and distribution efficiency were estimated using measurements of soil moisture, infiltration characteristics, water advance and recession time during different irrigation events. Applied depth of irrigation was estimated based on infiltration opportunity time at different points in the selected border strips. Stratified soil profile (sandy loam: 0-30 cm and sandy clay loam: 30-120 cm) of the selected fields caused the reduction in the infiltration rate to relatively very low value after 10-15 minutes creating favourable condition for uniformity of water application under surface irrigation. The water application efficiency of cotton field was 100 % as applied depth of irrigation was less than the required depth throughout the field plots and in wheat field it varied from 79.37-95.68 % indicating different degree of deep percolation loss. The observed water storage efficiency in different cotton fields varied from 72.92-90.08 % indicating under irrigation, whereas, in wheat field, it was 100 percent as applied depth of irrigation was more than the required depth. For a given field plot (border strip) water application efficiency increased with increasing value of advance ratio suggesting the need to incorporate the concept of advance ratio in the design process of border irrigation. Water distribution efficiency of cotton fields (91.37-98.18 %) and wheat field (82.26-96.13 %) indicated a relatively high degree of uniformity of water application.
