“…Loss of water to soil layers beyond the root system effective depth reflects the inefficient use of water and possible nutrient ions losses by leaching. In soils with high sand content, such as those with a sandy loam texture, water and nutrient losses can be even greater due to the low water-holding and cationic exchange capacity of the soil (Santoro et al, 2013;Franco et al ., 2017).…”

“…Irrigation management must be adapted in order to prioritize efficiency in the use of water while focusing on the orchard economic performance. Thereby, it becomes necessary to adapt the irrigation practice to the water availability, soil type, cultivation needs and to adopt management techniques that mitigate water losses through evaporation and percolation (Coelho et al, 2011;Santoro et al, 2013;Franco et al, 2017). Moreover, it is important to choose productive cultivars that tolerate the semi-arid climate and are responsive to irrigation, such as the Tainung No.…”

Irrigated farming enables producing papaya in Iaçu, located in the semiarid region of Bahia. However, water must be used efficiently, as the local availability of irrigation water resources is restricted. This study was conducted with the objective of defining the irrigation depth that provides the best agronomic performance of the Tainung No. 1 papaya cultivar, in a sandy loam soil of Iaçu, in the semiarid of Bahia, under the irrigation management conditions adopted by the producer. The experimental design used was of randomized blocks with four replicates. The experimental plot consisted of a row of plants, containing two border plants and twelve useful plants. Treatments corresponded to the total water depth of 1.103; 1.702; 2226; 2.751; 3.349 mm. Studied variables were height, leaf area, fruit number and yield, water use efficiency, fruit weight, fruit diameter and length, pulp width, pulp water content, pH, soluble solids and titratable acidity. Growth and production of the papaya tree responded positively to the applied water depths, but there was no interference in fruit quality. The yield showed linear adjustment, with a calculated maximum at 123.845 t ha-1 obtained for 3.349 mm. With the increasing water depth applied, there was a reduction in water use efficiency due to percolation water loss.

“…High concentrations of fertilizer may also cause increase in the soil solution electrical conductivity in short periods of time (COELHO et al, 2014). Franco et al (2017) point out that further studies are needed for the dissemination of this method in the management of fertigation, with emphasis mainly on the nutritional status of plants. If excess nitrate in the soil solution persists between crops, it can leach with rainwater.…”

Fertirrigation allows total control of the amount of applied fertilizers to the soil as a function of crop demand. Fertigation relies on monitoring of soil ions to obtain the sustainability of soil chemical conditions. The continuous evaluation of ions in the soil solution also contributes to the estimation of the cycling rate of chemical elements and nutrient leaching in the field. The objective of this work was (i) to evaluate nitrate, potassium, sodium and electrical conductivity in the soil solution submitted to different concentrations of injection solution and fertigation frequency during one cycle of the "Grande Naine" banana in a non-cohesive Yellow Latosol and (ii) to evaluate the effects of concentration and fertigation frequency on yields of banana crop. The experiment was carried out according to a randomized block design with six treatments and four replications in a 3 x 2 factorial scheme with three concentrations of the injection solution (3, 10 and 15 g L-1) x two fertigation frequencies (3 and 7 days). The treatments influenced the values of the ion concentration in the soil solution in the soil profile corresponding to the depths of 0-0.30 e 0.30-0.60 m. The concentration of the injection solution and the interaction frequency x concentration influenced the electrical conductivity and nitrate concentration of the soil solution. There was no significant effect of the injection solution and fertigation frequency on production variables.
