Other claims from this paper (11)
- Intervention effect Supplementary irrigation increased yield by 55%.
- Intervention effect Supplementary irrigation increased crop evapotranspiration by 39%.
- Intervention effect Supplementary irrigation maintained water productivity comparable to non-irrigated conditions.
- Observation Greatest supplementary irrigation yield and water-productivity improvements occurred with drip irrigation, moderate fertilizer rates and less than 150 mm irrigation.
- Observation This practice was especially effective in sandy soils with 1.5–2.0% SOC and 200–400 mm annual rainfall.
- Intervention effect Deficit irrigation reduced yield by 25% versus full irrigation.
- Intervention effect Deficit irrigation reduced evapotranspiration by 24% versus full irrigation.
- Intervention effect Deficit irrigation significantly enhanced irrigation water productivity by 28%.
- Intervention effect With 10–20% water saving under drip irrigation and specified fertilizer rates, deficit irrigation improved WP in sandy soils with 600–800 mm annual rainfall.
- Intervention effect Under those conditions, deficit irrigation avoided yield loss versus full irrigation.
- Association Irrigation water productivity increased with SOC levels.
