| The effects of irrigation water salinity, leaching fraction and its frequency of application on soil salinization were studied. Three water salinities (S1=1.54, S2=3.10 and S3=5.20 dS m-1) and two irrigation water depths associated with their application frequencies (W1=1.00 ETc; W2F1=1.25 ETc in all irrigations and W2F2=1.25 ETc when the irrigation water depth of W1 reached 100 mm where ETc is the crop evapotranspiration), were applied during the growing period of a grafted-cucumber crop in a greenhouse. The experimental design consisted of randomized blocks of 3 x 3 factorial scheme with 3 replications. Soil salinity at 0.1, 0.3 and 0.5 m depths increased linearly with salinity levels of water and the leaching fraction did not have any effect regardless... |

| ABSTRACT This study aimed to evaluate the distribution of salts along the soil profile, the biometric parameters and the yield of beet cultivars under different leaching fractions using saline effluent from fish farming, under the conditions of the Sub-middle São Francisco Valley. An experiment was conducted at the Caatinga Experimental Field of the Embrapa Semi-Arid, in 2013. The treatments were arranged in split plots composed of four leaching fractions (0, 5, 10 and 15%) in the plots, with saline effluent from fish farming, and three table beet cultivars in the subplots: Scarlet Super, Early Wonder 200 and Fortuna. The analysed parameters were: salt distribution along the soil profile, number of leaves, length and width of leaves and petioles, total and... |

| ABSTRACT This study aimed to evaluate the cultivation of forage sorghum subjected to different leaching fractions with saline effluent from fish-farming under semiarid conditions. The experiment was set in a randomized block design, with four blocks, in split plots, composed of four leaching fractions (0; 5; 10 and 15%) and three forage sorghum varieties ('Volumax', 'F305' and 'Sudão'). Irrigation was performed using saline effluent from fish farming with electrical conductivity of 2.5 dS m-1. The analyzed variables were: plant height; stem diameter; width, length and number of leaves; fresh and dry matter yield, and relative contents of potassium and sodium in the shoots. Forage sorghum under saline effluent irrigation and leaching fraction of 15% shows a... |
