Abstract:Various maize irrigation treatments including full and deficit irrigation were used to calibrate and validate the soil water balance and irrigation scheduling model SIMDualKc at Paysandú, western Uruguay. The model adopts the dual crop coefficient approach to partition actual evapotranspiration (ET c act ) into actual transpiration (T c act ) and soil evaporation (E s ). Low errors of estimation were obtained for simulating soil water content (Root mean square errors (RMSE) ď 0.014 cm 3¨c m´3 with calibrated parameters, and RMSE ď 0.023 cm 3¨c m´3 with default parameters). The ratio E s /T c act ranged from 26% to 33% and E s /ET c act varied from 20% to 25%, with higher values when the crop was stressed offering less soil coverage. Due to rainfall regime, runoff and deep percolation were quite large. The Stewarts phasic model was tested and used to predict maize yield from T c act with acceptable errors, in the range of those reported in literature. Water productivity values were high, ranging 1.39 to 2.17 kg¨m´3 and 1.75 to 2.55 kg¨m´3 when considering total water use and crop ET, respectively. Using a 22-year climatic data series, rainfed maize was assessed with poor results for nearly 40% of the years. Differently, alternative supplemental irrigation schedules assessed for the dry and very dry years have shown good results, particularly for mild deficit irrigation. Overall, results show appropriateness for using SIMDualKc to support the irrigation practice.

“…This implies that in this study the soil moisture deficits during vegetative growth and development had only a small effect on internodes elongation, which supports the finding in some studies (Djaman et al, 2013;Elzubeir & Mohamed, 2011). In contrast, some studies reported that water stress significantly affected maize plant height where deficit irrigation typically resulted in shortened plants (Aydinsakir et al, 2013;Çakir, 2004;Karasu et al, 2015).…”

As the challenges toward increasing water for irrigation become more prevalent, knowledge of crop yield response to water can facilitate the development of irrigation strategies for improving agricultural productivity. Experiments were conducted to quantify maize yield response to soil moisture deficits, and assess the effects of deficit irrigation (DI) on water productivity (water and irrigation water use efficiency, WUE and IWUE). Five irrigation treatments were investigated: a full irrigation (I 1 ) with a water application of 60 mm and four deficit treatments with application depths of 50 (I 2 ), 40 (I 3 ), 30 (I 4 ), and 20 mm (I 5 ). On average, the highest grain yield observed was 1008.41 g m −2in I 1 , and water deficits resulted in significant (p < .05) reduction within range of 6 and 33%. This reduction was significantly correlated with a decline in grain number per ear, 1000-grain weight, ear number per plant, and number of grain per row. The highest correlation was found between grain yield and grain number per ear. The WUE and IWUE were within range of 1.52-2.25 kg m , respectively. High water productivity without significant reduction in yield (<13%) for I 2 and I 3 compared to the yield in I 1 indicates that these water depths are viable practices to promote sustainable water development. Also, for assessing the benefits of irrigation practices in the region crop water production functions were established. Maize yield response to water stress was estimated as .92, suggesting the environmental conditions are conducive for implementing DI strategies.

“…In the same way, Aydinsakir et al (2013) found that protein content in maize grain was influenced by water deficit, with a decreasing level around 61.53 and 38.46% in ʽAnt-190ʼ and ʽSafakʼ varieties, respecting to a full irrigation treatment.…”

In México, around 82% of the total production of maize is grown under rainfed conditions leading to a water stress environmen affects physiologic and biochemical process of the plant. Maize bran is a composited plant material consisting mainly in al and pericarp; the cell walls of these tissues are composed of proteins, non potential bioactive substances for human nutrition. In this research the bran of three genotypes of maize phenols and phenolic acids was performed in the bran of development stage increased protein levels of content, water stress increase increased in water stress treatment at levels of 1.28, 2.26 and 3.66% in treatment decreased the levels of total phenols and hydroxycinnamic acids in the three maize hybrids analysed. Reduction of t was 35.34, 5.59 and 31.57% for acids decreased 17. 74, 23.93, 29.83% in
