A field experiment was conducted at Anbil Dharmalingam Agricultural College and Research Institute, Tiruchirapalli during winter season of 2019 to study the effect of subsurface drip irrigation- fertigation regimes on stalk yield, seed cotton yield and economics of high density cotton cultivation in sodic soil. The experiment was laid out in factorial randomized block design with three replications. The treatments consisted of combination of two factors viz., four subsurface drip irrigation levels (I1 – 0.4 Epan,I2 – 0.6 Epan, I3 – 0.8 Epan and I4– 1.0 Epan) and three fertigation levels (N1 – 100% RDF, N2 – 125%, RDF and N3– 150% RDF). The results revealed that subsurface drip irrigation level of 1.0 Epan registered higher stalk yield as well as seed cotton yield and this was found comparable with 0.8 Epan for seed cotton yield alone. Among fertigation levels 150% RDF registered higher stalk yield but the seed cotton yield was found higher under fertigation of 125% RDF. Among interaction, combination of 1.0 Epan + 125% RDF recorded higher gross return, net return and B:C ratio. The study shows that subsurface drip irrigation-fertigation of 1.0 Epan + 125% RDF may be recommended for compact cotton varieties for better productivity and profitability in sodic soil condition.
