Effect of surface water and underground water drip irrigation on cotton growth and yield under two different irrigation schemes.

ABSTRACT: To investigate the effect of surface water and underground water drip irrigation on cotton yield, dry matter accumulation and nutrients uptake, two consecutive field experiments were conducted. The first experiment (different mixing ratio irrigation) comprised of five ratios of underground water to surface water including; 1:0 (U), 0:1 (S), 1:1 (U:S = 1:1), 1:2 (U:S = 1:2) and 1:3 (U:S = 1:3). Whereas, the second experiment (round irrigation) comprised of eight treatments including: 1:3 (T1), 2:2 (T2), 3:1 (T3), {S:U 3:1 (T4)}, 2:2 {S:U (T5)}, 1:3 {S:U (T6)}, 4:0 (T7) and 0:4 (T8). The average concentration of leaves dry matter after 8th irrigation in different mixing ratio experiment was significantly increased by 131.2% (S), 34.4% (U: S = 1:1), 59.3% (U: S = 1:2), and 93.7% (U: S = 1:3),
