The final, formatted version of the article will be published soon.

Citrus is considered a highly water and nutrient sapping crop, with several previous efforts focusing on improving water productivity (WP) and nutrient-use-efficiency (NUE). However, such efforts highlighting the performance of subsurface drip irrigation (SDI) versus drip irrigation (DI) in black clay soil (Vertisol) growing Nagpur mandarin are very limited . This study evaluated six treatments: T 1 (SDI with double inline laterals at 100 cm radially from trunk and 30 cm vertically placed into the soil , drippers spaced 30 cm apart), T 2 (SDI with double inline laterals at 100 cm radially from trunk and 30 cm vertically placed into the soil , drippers spaced 40 cm apart), T 3 (SDI with double inline laterals at 100 cm radially from trunk and 30 cm vertically placed into the soil , drippers spaced 50 cm apart ), T 4 (SDI with double inline laterals at 100 cm radially from trunk and 30 cm vertically placed into the soil , drippers spaced 60 cm apart), T 5 (DI with double online laterals at 100 cm from trunk with 6 drippers 60 cm apart , control as farmers practice ), and T 6 (DI with ring type online laterals at 10cm from trunk with 12 drippers tree -1 placed 60 cm apart). These treatments were evaluated studied for their response on growth performance, fruit yield, fruit quality, WP, and leaf nutrients composition . Significantly higher WP and lower water requirement were observed with SDI (7.96-10.73 kg m -³ and 13260 L plant -1 year -1 ) compared to DI treatments (2.79-3.04 kg m -³ and 32670 L plant -1 year -1 ). These observations were associated with 25.29 % higher fruit yield with SDI treatments over DI treatments. Similarly, fruit quality parameters viz., juice content and total soluble solids (TSS) showed 6.65 % and 1.17% 0 Brix , respectively, higher with SDI than DI treatments. Consequently, SDI treatments registered leaf N, P, K,
