Abstract: Field experiments were conducted to study the impact of supplemental irrigation and crop residue mulch on Barnyard millet (Kuthiraivali – CO2) cultivated in dryland areas of southern part of Tamil Nadu. The experimental was laid out in randomized block 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, during 2017-18 in barnyard millet (CO2), higher grain yield (1650 kg/ha), gross income (33000 Rs/ha) and B:C ratio (1.65) was recorded in supplemental irrigation twice through mini portable sprinkler and crop residue mulch 2.5 t/ha (T3) followed by supplemental irrigation twice through mini portable sprinkler (T2). The results of the study indicated that farm pond is an effective technology for harvesting andproviding water for supplemental irrigation.
