“…Yield attributes such as stem length, ear height, number kernels row -1 , grain weight, grain yield, biomass yield and harvest index of maize were adversely affected by drought stress (EL Sabagh et al, 2017a). The similar type impacts of water deficit and well-water regimes on the yield traits and grain yield of maize had been reported in several studies (Cakir, 2004;Moser et al, 2006;Rivera-Hernandez et al, 2010). Shoa Hoseini et al (2007) and Golbashy et al (2010) reported that under drought stress, reduction in the total grain yield of maize are attributed to the reductions in number of kernels per row and total number of kernels per ear.…”

Maize is an essential dietary component in human food and in animal feed formulation. With the rising trend of global climate change, grain yield and quality losses of maize are expected to increase, because of various biotic and abiotic stress in all over the world. Among these, drought is most considerable one; it remarkably influences growth and yield traits of maize. Hence, the improvement of drought tolerant maize genotypes has potential to stabilize and even though increases the grain yield of maize. Therefore, developing cultivars tolerant to drought stress is a challenge for breeders. There are two ways to mitigate drought stress in maize production, either by developing and practicing improved drought

“…For many plant species under drip irrigation, there exists a specific SWP irrigation threshold range within which the plant yield varies little, but when the SWP is lower than this range the yield will decrease significantly. For example, the yield of a hybrid poplar (Hansen 1988), sweet corn (Zea mays L.) (Rivera-Hernández et al 2010), Leymus chinensis (Liu et al 2011) and chili pepper (Capsicum annuum L.) (Liu et al 2012) varied insignificantly when the SWP irrigation threshold ranged from −30 to −70 kPa, −5 to −30 kPa, −5 to −10 kPa and −10 to −40 kPa, respectively, whereas as the thresholds declined beyond these ranges their yield could decrease significantly. Our results indicated that, as the SWP irrigation threshold varied between −25 and −75 kPa, the yield of mature P. tomentosa plantations under SDI would not change significantly, although there were apparent or significant differences in soil water availability, irrigation amount and E among the SWP treatments.…”

In order to find the optimal subsurface drip irrigation (SDI) scheduling for mature triploid Populus tomentosa plantations in the North China Plain, a field experiment was conducted in 2010 and 2011 to investigate the effects of SDI at different soil water potential (SWP) thresholds on the growth and transpiration of a P. tomentosa plantation when it was six and seven years old. The experiment included three SWP treatments, which initiated irrigation when the SWP at 20 cm depth and 10 cm distance from a drip emitter reached −25 (T 25 ), −50 (T 50 ) and −75 (T 75 ) kPa, respectively. A control non-irrigation treatment (CK) was also included. Long-term SWP, soil water content (SWC), transpiration, tree growth, meteorological factors and groundwater level were monitored. Results showed that SDI influenced the SWC only in 0-80 cm of soil. From April to July, on average, the cumulative stand-level transpiration on a ground area basis (E) and growth of basal area at breast height accounted for 81% and 93% of their corresponding wholeseason values, while the cumulative reference crop potential evapotranspiration (ET 0 ) was 43% higher than the rainfall. In contrast, from August to October, the growth rate of P. tomentosa was very slow, while the cumulative rainfall was 36% higher than ET 0 and the average groundwater level was relatively high (125 cm). Relative to CK, the E under the SWP treatments was significantly (P < 0.05) increased by 20-73%. Decreasing the SWP irrigation threshold from −25 to −50 kPa significantly reduced E by 31% (P < 0.05), but decreasing the threshold from −50 to −75 kPa did not further reduce P. tomentosa E. Relative to CK, T 25 , T 50 and T 75 increased the annual above-ground dry biomass (ADB) increment by 54% (P < 0.05), 34% (P < 0.05) and 24% (P > 0.05) in 2010, and by 28% (P > 0.05), 29% (P > 0.05) and 32% (P < 0.05) in 2011, respectively. However, no significant difference in ADB increment was detected among the SWP treatments. Based on these results, it can be concluded that when planting P. tomentosa at sites with similar characteristics to ours in the North China Plain: (1) SDI could be promoted in the cultivation of P. tomentosa to improve tree growth; (2) a range of −50 to −75 kPa at a depth of 20 cm and 10 cm distant from a drip emitter is recommended as the irrigation threshold for scheduling SDI in P. tomentosa plantations and (3) irrigation should be applied between April and July, while drainage should be implemented between August and October.

“…Sweet corn yields did not differ between SWT irrigation criteria or irrigation systems, but less water was required and less nitrate was leached with tape. Rivera-Hernandez et al (2010) recommended 30 kPa for sweet corn grown in Mexico; Rhoads and Stanley (1973) recommended 30 kPa for corn grown for grain in Florida. Thomson and Fisher (2006) used a SWT irrigation criterion of 60 kPa for developing evapotranspiration (ET) irrigation scheduling for cotton (Gossypium hirsutum) in Mississippi.…”

A fundamental way to schedule irrigation is through the monitoring and management of soil water tension (SWT). Soil water tension is the force necessary for plant roots to extract water from the soil. With the invention of tensiometers, SWT measurements have been used to schedule irrigation. There are different types of field instruments used to measure SWT, either directly or indirectly. Precise irrigation scheduling by SWT criteria is a powerful method to optimize plant performance. Specific SWT criteria for irrigation scheduling have been developed to optimize the production and quality of vegetable crops, field crops, trees, shrubs, and nursery crops. This review discusses known SWT criteria for irrigation scheduling that vary from 2 to 800 kPa depending on the crop species, plant product to be optimized, environmental conditions, and irrigation system. By using the ideal SWT and adjusting irrigation duration and amount, it is possible to simultaneously achieve high productivity and meet environmental stewardship goals for water use and reduced leaching.
