“…On the other hand, a linear relationship has been reported between corn grain yield and evapotranspiration (Gencoglan and Yazar, 1999;Yazar et al, 2002;Cakir, 2004;Payero et al, 2006). Overman and Martin (2002) confirmed the linear relation between grain and silage yield response to irrigation for corn.…”

“…Many researchers found water deficit reduced leaf area (Pandey et al 2000), plant height (Soler et al 2007), shoot growth (Stone et al 2001), and plant yield (Payero et al 2006). However, over-irrigation can increase agricultural salinization and cause the destruction of agriculture lands (Skaggs et al 2006).…”

L. 2015. The effects of different water and nitrogen levels on yield, water and nitrogen utilization efficiencies of spinach (Spinacia oleracea L.). Can. J. Plant Sci. 95: 671Á679. Water and nitrogen (N) are important factors that affect crop yield. The objective of this study was to explore the interactive effect of water and nitrogen on biomass production, yield and growth responses, water and nitrogen use efficiency of winter-grown spinach. A field experiment was grown with treatments of varying water (W) and nitrogen (N) levels near Shanghai, China. Leaf area, shoot biomass and height of spinach increased with the application of N in the well-watered treatment. The highest chlorophyll content was found in spinach treated with N 2 (170 kg ha(1 nitrogen). A response surface analysis was done on plant height, leaf number, leaf weight, and plant yield of each spinach plant at different water and nitrogen levels. The equation for each of the response surfaces was taken and solved for the mathematical optimum of the curves. Abundant water supply resulted in the highest spinach yield. Yield of spinach increased with N application rates but decreased when the N was excessive. Compared with the low water treatment (W 3 ), a higher N leaching ratio was observed in the high water treatment (W 1 ), regardless of N treatment. With the increase of N application, N use efficiency of spinach significantly decreased, while water use efficiency of spinach increased. In conclusion, water levels between 36.15 cm and 42 cm, and nitrogen applications between 86 and 152.74 kg ha(1 could be recommended as the optimal treatment for spinach growth.

“…The ET c was lower in season 1 than in season 2, although no differences were observed in grain yield. PAYERO et al (2006) found an excellent correlation between grain yield and ET c when there was no stress, but this relationship varied from year to year. For GRASSINI et al (2009), high (≈>25°C) and low (≈<21ºC) daily average temperatures at pollination and grain fill reduce grain yield, because of a reduction in the period of the grain fill and an increase in the respiratory rate (in the first case), and a reduction in the photosynthesis rate (in the second case).…”

Simulation of soil water balance and partitioning of evapotranspiration of maize grown in two growing seasons in Southern Brazil

The objective of this study was to simulate the variation of the available soil water during maize crop growth, in two different sowing times (first and second growing season), using a drip irrigation system. The treatments consisted of different irrigation strategies (full to deficit). The SIMDualKc simulation model was used to determine the daily soil water balance and crop evapotranspiration using the dual crop coefficient approach. Soil, climate, crop and irrigation parameters were used as input data. Two experiments were carried out in a rainout shelter composed of two metallic structures (16x10m) in the city of Santa Maria, Rio Grande do Sul, Brazil, during 2010/11 (second crop, season 1) and 2011/12 (first crop, season 2) growing seasons, under no-tillage system. The simulations showed that all the irrigation management strategies used in season 2 resulted in soil water deficit, while only two strategies showed deficit in season 1. Results showed good agreement between observed and simulated soil water data, with an R2 ranging from 0.86 to 0.99 and the root mean square error ranging from 2.7 to 5.6% of the total available water for seasons 1 and 2, respectively. The observed results of water balance showed that maize grown in season 2 presented higher water consumption compared to season 1, due to the higher atmospheric demand of season 2. The SIMDualKc model allowed the partitioning of crop evapotranspiration into soil evaporation and crop transpiration, demonstrating that the vegetative growth subperiod presented the greatest differences between the two seasons compared to the others growth phases.
