A field experiment was conducted during kharif season of 2011-12 to 2016-17 at Main Dry Farming Research Station, JAU, Targhadia to study the rainwater management for sustaining cotton productivity in medium black soil under dry farming condition. Main plot comprised of two tillage practices viz., ploughing every year up to 30 cm in set row(T1) and ploughing alternate year up to 30 cm in set row (T2) and sub plot of five management practices viz., FYM @ 10 t/ha + kaolin @ 4% spray (M1), FYM @ 10 t/ha + guar gum @ 0.3% spray (M2), gypsum@ 1 t/ha + kaolin @ 4% spray (M3), gypsum@1t/ha + guar gum @ 0.3% spray (M4) and control(M5) was evaluated in split plot design with four replications. On the basis of six year pooled results, significantly higher seed cotton and stalk yield was obtained under application of FYM @ 10 t/ha + kaolin @ 4% spray (M1) and it was remained at par with the application of FYM @ 10 t/ha + guar gum @ 0.3% spray (M2) in management practices. Whereas individual effect of tillage practices and interaction effect of tillage and management practices on seed cotton yield and stalk yield were found non-significant. Maximum rain water and crop water use efficiency as well as net returns with B:C ratio were recorded in ploughing every year up to 30 cm in set row (T1) and application of FYM @ 10 t/ha + kaolin 4 % spray(M1) under tillage and management practices, respectively.
