Subsurface drainage is a prerequisite to grow winter crops in the consolidated paddy fields in Northern Iran. A four-year study (2011)(2012)(2013)(2014)(2015) was conducted to quantify the effects of subsurface drainage on the saturated hydraulic conductivity, water table, drain discharge and winter crop yields. Subsurface drainage systems with two drain depths of 0.65 and 0.90 m and two drain spacings of 15 and 30 m were installed at the consolidated paddy fields of Sari Agricultural Sciences and Natural Resources University, Iran. During four successive winter seasons, the water table depth and drain discharge were measured daily. Soil saturated hydraulic conductivity was measured twice; before drainage system installation and four years following the installation. Canola grain yields were determined at harvest of each cultivation season. During the study period, the soil saturated hydraulic conductivity increased with the highest increase in the top 0-30 cm. The deeper drains were more effective in controlling the water table compared to the shallow, and the daily drain discharge of the deeper drains in the fourth year were higher than those of shallow drains. The canola grain yield of all drainage systems increased significantly by the seasons, and the largest difference in canola grain yield between first and fourth seasons was 2191 kg¨ha´1 (318% increase) in the fields with 0.90 m drain depth and 30 m drain spacing. Totally, it became clear that installation of subsurface drainage systems with 0.90 m depth and 30 m spacing in the paddy fields of Northern Iran can be recommended to achieve high yield of winter crop, soil condition improvement, and multi-purpose land use.

“…Different responses of the water table profile to drainage are related to specific flow patterns in paddy fields. Puddling, a traditional practice in paddy fields for controlling percolation losses, causes the formation of a less conductive soil layer (a hardpan) below a plow pan (Darzi-Naftchali et al, 2013). This layer causes water to horizontally flow from between the drains to the backfilled trench in a surface soil layer and then vertically into the drains (Ogino and Ota, 2007 …”

“…Basal fertilizers were applied before rice transplanting as follows: 140 kg ha −1 triple superphosphate in 2011; 100 kg ha −1 triple superphosphate, 100 kg ha −1 potassium sulfate, and 80 kg ha −1 urea in 2014; and 50 kg ha −1 triple superphosphate, 50 kg ha −1 potassium sulfate, and 100 kg ha While the usual water management practice for local rice fields is continuous flooding as it helps control weeds and pests Âr and s are the residual and saturated water contents, respectively, Ks is the saturated hydraulic conductivity, b is bulk density and ␣, n, and l are the shape factors in the van Genuchten-Mualem model (van Genuchten, 1980). (Darzi-Naftchali et al, 2013), two types of water managements were followed during this experiment: midseason drainage (MSD) and alternative wetting and drying (AWD). Under both managements, the plots were continuously flooded (with about 5 cm of standing water) during 3-4 weeks after transplanting, and suitable conditions for harvesting were created by end-season drainage several days before the harvest.…”

Quantifying the impacts of waterlogging on cotton at different growth stages: A case study in Hubei Province, China

Waterlogging severely restricts cotton (Gossypium hirsutum L.) production worldwide. To assess the impacts of waterlogging on cotton yield, a series of field experiments with multi-form waterlogging were conducted during four cotton growth stages in Hubei Province, China from 2003 to 2011. Moreover, regional waterlogging events were characterized by the sum of excess rainstorm amount index (SER) and the sum of excess standardized precipitation and evapotranspiration index (SESPEI); accordingly, the spatiotemporal variations in waterlogging in Hubei Province during 1961-2019 were analyzed. The results showed that the 1980s was the most waterlogging-prone decade and northeastern Hubei was the most waterlogging-prone region for Hubei. The impact of surface waterlogging on cotton was greater than that of subsurface waterlogging, and the impact of their combined stress was lower than the additive effects of individual stresses. The most waterlogging-sensitive cotton growth stage was the flowering and boll-forming stage, whereas the most waterlogging-proneness growth stage was the budding stage. A normalized waterlogging index integrating both waterlogging sensitivity and proneness indicated that the budding and the flowering and boll-forming stages were the periods when cotton suffered the greatest waterlogging impacts. Both the SESPEI and SER were significantly (p < .05) and negatively related to the detrended cotton yield, and the former was found more efficient in describing the negative effects of waterlogging. In conclusion, different forms of waterlogging should be accounted for in-field drainage schedules, and extra attention should be paid during the budding and the flowering and boll-forming stages of cotton, especially for northeastern Hubei.
