Abstract
The article evaluates drip irrigation of cotton (variety S-4727) compared with furrow irrigation on slightly saline light and medium sandy soils of Karakalpakstan with groundwater at a depth of 1.5–2.5 m. The 2025–2026 field experiment had three treatments: furrow irrigation (production control); drip irrigation with pre-irrigation soil moisture of 70–80–65% of field capacity; and drip irrigation at 80–80–65%. Drip irrigation reduced the seasonal irrigation norm by 34–36% on light soils and by 25–28% on medium sandy soils, and raised seed cotton yield by 6.6–11.2 c/ha. Salt accumulation in soil and groundwater was markedly lower under drip irrigation. The 70–80–65% regime proved the most effective (profitability 75%).
