“…The EC of the irrigation water reduced the SFW, SDW, SWW, and TWW at 20 DAS in 11, 1, 10, and 11 g plant -1 , resulting in decreases of 26%, 21%, 26%, and 24%, respectively (Table 5). These decreases are due to morphological changes during germination and initial development of the plants when salt solutions are used (Saeidi-Sar et al, 2013;Guilhen et al, 2016). --------------------------------------------------------g ---------------------------------------------------- Roots of common bean plants are more tolerant to salinity than their shoots because roots have faster osmotic adjustments and slower turgor loss (Oliveira et al, 2016).…”

When it is said about quality and quantity of water supplied through irrigation, for common bean cultivation, it is considered sensitive to water and saline stress. The objective of this work was to evaluate the biomass accumulation and growth of common bean plants (Phaseolus vulgaris L.) subjected to irrigation with different water depths, using water with different electrical conductivities. The experiment was carried out in pots under a protected environment located in an experimental area of the Federal Institute of Goiás, Rio Verde Campus, in the city of Rio Verde, Goiás. The design was a randomized complete block design in a 4 × 2 factorial scheme with three replications. 25, 50, 75 and 100% of the evapotranspiration of the crop, and two types of electrical conductivity of irrigation water equal to 0.6 and 3.0 dS m-1. All variables were analyzed using the SISVAR® software, whose mean values for the electrical conductivity treatments were compared by Tukey test at 0.05% probability and water replacement by regression analysis, when significant. The use of irrigation water with electrical conductivity of 3 dS m-1 reduces plant height, number of green leaves and stem diameter at 35 days after sowing, thus reducing dry biomass accumulation and aerial part water accumulation at 20 and 70 days after sowing. The deleterious effects under the dry mass of the aerial part at 70 days after sowing, when using an electrical conductivity of 3 dS m-1, are accentuated by the increase of the water dephts.

“…The WUE was expressed in kilograms of dry matter or corn grains per cubic meter of water (kg m -3 ). It is important to note that, due to the nature of this variable, it was not included in the database for statistical analysis, avoiding multicollinearity and redundant results (Guilhen et al, 2016;Lindner and Pitombo, 2016).…”

This study aims to analyze the production components and the water-use efficiency of corn cultivated with irrigation depths, and also to verify the utilization of multivariate analysis is suitable to highlight the relevant information. Hybrid corn AG 7088 was used as plant material. Two experiments were conducted under field conditions at two different experimental periods between the months of April and December 2015 in a randomized block design with six irrigation depths [50, 75, 100 (control), 125, 150, and 175% replacement of evapotranspiration -ET 0 ] and four replications. At 120 days after sowing, the following variables were evaluated: mass of one thousand grains, number of spikes per plot, yield of dry grains, ear length, ear diameter, number of lines per ear, number of grains per line, number of ears grain per spike, grain mass per spike, cob mass, spaghetti mass, and mass of straws. The results showed that production components and water use efficiency of hybrid corn AG 7088 were not affected by the varying water depths in the first experimental period. In the second period, the increase in water depth supported a gain in the mass of a thousand grains, dry grain yield, grain number per row, grain number per ear, corn cob mass and mass of dehusked ear, reducing the efficiency of water use. The use of multivariate analysis was able to reduce the multi-dimensional space of the set of variables in the three Principal Components with relevant information to highlight differences between irrigation depths and experimental periods.
