Abstract: Field experiments were conducted to study the effect of supplemental irrigation and crop residue mulch on little millet(CO4) cultivated in dryland areas of southern part of Tamil Nadu. The experimental was laid out in randomizedblock design with three treatments viz., T1 – Farmers practice (rainfed cultivation without supplemental), T2 – Supplemental irrigation twice through mini portable sprinkler and T3 – Supplemental irrigation twice through mini portable sprinkler and crop residue mulch 2.5 t/ha with three replications. The yield and economic analysis reveals that, in samai the highest BC ratio (0.67) and RWUE (1.59) was obtained in supplemental irrigation twice through mini portable sprinkler and crop residue mulch 2.5 t/ha treatment (T3). The results of the study showed that farm pond is an effective technology for harvesting andproviding water for supplemental irrigation.
